Firewall, Components, Working, Types, Challenges

indiafreenotesby indiafreenotes1

Firewall is a network security system that monitors, filters, and controls incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between trusted internal networks and untrusted external networks, such as the internet, to prevent unauthorized access and potential cyberattacks. Firewalls can be hardware-based, software-based, or a combination of both. They examine data packets, allowing only legitimate traffic while blocking malicious or suspicious activity. By enforcing access policies, firewalls protect systems from hackers, malware, and unauthorized users, ensuring data confidentiality, integrity, and availability within networks and computer systems.

Components of Firewall:

  • Packet Filtering

Packet filtering is a fundamental firewall component that examines data packets entering or leaving the network. It analyzes packet headers, such as IP addresses, port numbers, and protocols, to determine whether to allow or block the traffic based on predefined rules. This method is fast and efficient, but it cannot inspect the actual data content, making it vulnerable to advanced threats. Packet filtering works as the first line of defense, ensuring only traffic matching the organization’s security policies is permitted. While simple, it provides essential control over basic network traffic flow.

  • Proxy Service

A proxy service acts as an intermediary between users and the internet. Instead of direct communication, the firewall’s proxy server fetches requests on behalf of the user, providing an additional security layer. It hides the internal network structure, preventing attackers from identifying devices within the system. Proxies can also perform deep packet inspection, cache frequently accessed content, and filter requests based on content or user behavior. By breaking direct connections, proxies reduce exposure to threats, enhance privacy, and enforce security policies, making them essential for controlling application-level communication.

  • Stateful Inspection

Stateful inspection, also called dynamic packet filtering, monitors the state and context of active network connections. Unlike basic packet filtering, which checks packets in isolation, stateful inspection analyzes the entire traffic session, ensuring packets are part of a legitimate, established connection. It maintains a state table to track sessions and validates whether incoming packets match expected patterns. This prevents unauthorized attempts like spoofing or session hijacking. Stateful inspection provides a balance of strong security and performance, offering a more robust solution for modern networks compared to simple filtering techniques.

  • Network Address Translation (NAT)

NAT is a firewall component that conceals internal IP addresses by translating them into a single public IP address for external communication. This masking improves security by hiding the network’s internal structure from outsiders. NAT also helps conserve limited IPv4 addresses by allowing multiple devices to share one public IP. In addition to protecting devices from direct external exposure, NAT ensures efficient traffic management. Combined with firewall rules, NAT minimizes the risk of attacks on internal systems, making it a critical function in safeguarding organizational networks from potential cyber intrusions.

  • Virtual Private Network (VPN) Support

Many firewalls include VPN support to establish secure, encrypted tunnels for remote access. VPN-enabled firewalls allow employees or authorized users to connect to the organization’s internal network safely over the internet. By encrypting traffic, VPNs ensure confidentiality, integrity, and authentication, protecting sensitive data from interception. They also enforce access control by verifying user credentials before granting entry. VPN integration in firewalls is especially important for organizations with remote workers, branch offices, or cloud-based operations, as it ensures safe communication and resource sharing while maintaining the network’s security perimeter.

  • Intrusion Detection and Prevention (IDPS)

Intrusion Detection and Prevention Systems (IDPS) in firewalls monitor network traffic for suspicious activity or policy violations. They use signature-based, anomaly-based, or behavioral techniques to identify threats like malware, denial-of-service attacks, or unauthorized access attempts. An IDS alerts administrators about suspicious events, while an IPS actively blocks or mitigates malicious traffic in real-time. Integrating IDPS with firewalls provides layered defense against both known and emerging cyber threats. This proactive security feature ensures threats are detected early, reducing damage and maintaining network integrity.

  • Logging and Monitoring

Logging and monitoring are essential firewall components that record details of all traffic and activities passing through the firewall. Logs include information such as source and destination IPs, ports, protocols, and timestamps of network events. These records help administrators analyze traffic patterns, detect anomalies, and investigate security incidents. Real-time monitoring enables quick response to attacks, while historical logs support audits and compliance requirements. By offering visibility into network behavior, logging and monitoring strengthen overall security posture, enabling organizations to improve firewall policies and anticipate potential threats more effectively.

  • Content Filtering

Content filtering in firewalls controls access to inappropriate, harmful, or non-business-related websites and online resources. By inspecting web traffic, the firewall blocks access to sites containing malware, phishing, or offensive content, ensuring employee productivity and organizational safety. Content filtering can also restrict access based on categories like social media, streaming platforms, or gaming. It often integrates with URL filtering databases or keyword-based restrictions. Beyond security, content filtering helps organizations comply with regulations, maintain bandwidth efficiency, and protect users from harmful online material.

How does a Firewall Work?

  • Traffic Monitoring and Filtering

A firewall works by continuously monitoring all incoming and outgoing network traffic. It acts as a security guard, examining data packets that travel between a private network and external sources like the internet. Each packet is inspected based on pre-set rules such as IP addresses, port numbers, and protocols. If a packet meets the allowed criteria, it is permitted to pass; otherwise, it is blocked. This packet-filtering process ensures that only safe and authorized communication enters or leaves the network, providing a first line of defense against unauthorized access.

  • Access Control

Firewalls enforce access control by defining which users, devices, or applications can interact with the network. Administrators configure policies that specify permitted services, such as web browsing or email, while restricting unwanted ones. By applying these rules, the firewall creates barriers between trusted and untrusted zones, ensuring critical systems are shielded. Access control may be based on IP addresses, domain names, or authentication credentials. This mechanism helps prevent attackers, malware, or unauthorized users from exploiting the network. Essentially, firewalls limit exposure by ensuring that only approved communication is allowed, maintaining both privacy and system integrity.

  • Stateful Inspection

Modern firewalls use stateful inspection, a method that not only checks packet headers but also tracks the state of active connections. Instead of treating each packet independently, the firewall records session details in a state table. It verifies whether a packet belongs to an established, legitimate connection or is suspicious. For example, if a packet claims to be a response to a request but no such request was sent, the firewall will block it. This deeper inspection provides more accuracy and security than simple packet filtering, helping to detect and stop sophisticated cyberattacks effectively.

  • Protection Against Threats

A firewall acts as a defense mechanism by blocking malicious traffic, viruses, worms, and hacking attempts before they reach the network. Many firewalls integrate intrusion detection, intrusion prevention, and content filtering to strengthen security. They can identify unusual patterns, such as port scanning or denial-of-service (DoS) attempts, and take immediate action. By controlling both inbound and outbound traffic, firewalls prevent sensitive data from being leaked or stolen. This multi-layered protection reduces vulnerabilities and ensures the confidentiality, integrity, and availability of network resources, making firewalls a critical safeguard in cybersecurity.

Types of Firewalls:

  • Packet-Filtering Firewall

A packet-filtering firewall is the most basic type, which examines data packets moving across a network. It checks source and destination IP addresses, port numbers, and protocols against predefined rules. If the packet matches the rules, it is allowed; otherwise, it is blocked. This firewall works at the network layer and is efficient but limited because it does not inspect the content of packets. While it provides quick filtering, it is vulnerable to sophisticated attacks that disguise malicious data. It is best suited for small networks requiring simple, cost-effective protection without complex monitoring.

  • Stateful Inspection Firewall

A stateful inspection firewall, also known as a dynamic packet filter, goes beyond simple packet filtering. It monitors active connections and keeps track of the state of network sessions using a state table. Instead of only checking packet headers, it verifies whether the packet belongs to an existing, legitimate session. This makes it more secure than basic firewalls, as it prevents malicious or unsolicited traffic. Stateful firewalls are commonly used in modern networks because they balance performance and security. They are effective in protecting against unauthorized access and attacks while still maintaining efficient traffic flow.

  • Proxy Firewall (Application-Level Gateway)

A proxy firewall acts as an intermediary between users and the internet by filtering requests at the application layer. Instead of allowing direct communication, it processes requests and forwards them to the destination on behalf of the user. This hides the internal network, offering strong anonymity and protection. Proxy firewalls can inspect data deeply, block harmful content, and prevent direct exposure to threats. However, they may slow down network performance due to heavy traffic inspection. They are useful in organizations needing strict security and monitoring, especially for web browsing, email filtering, and application-level access control.

  • Next-Generation Firewall (NGFW)

Next-Generation Firewalls combine traditional firewall features with advanced capabilities like intrusion prevention systems (IPS), deep packet inspection, and application awareness. Unlike standard firewalls, NGFWs can identify and control applications regardless of port, protocol, or encryption. They also integrate features like malware protection, URL filtering, and threat intelligence. This makes them highly effective against sophisticated cyber threats. NGFWs provide greater visibility into network traffic, enabling organizations to enforce more granular security policies. Although costlier, they are widely adopted by enterprises that require robust, multi-layered security to protect against modern attacks and evolving cyber risks.

Challenges of Firewalls:

  • Limited Protection Scope

Firewalls are effective at blocking unauthorized access, but they cannot detect or prevent all types of cyber threats. They mainly monitor incoming and outgoing traffic, which means attacks like phishing, malware hidden in encrypted traffic, or insider threats may bypass them. Additionally, firewalls do not provide full protection against social engineering or sophisticated zero-day attacks. Relying solely on a firewall without other security measures creates vulnerabilities. To overcome this limitation, organizations must use firewalls in combination with intrusion detection systems, antivirus software, and strong user awareness programs to ensure a multi-layered defense strategy.

  • Performance and Latency Issues

Firewalls, especially advanced ones like next-generation firewalls (NGFWs), can introduce latency by analyzing packets, inspecting content, and filtering applications. High traffic volumes may slow down network performance, causing delays for users and critical business applications. In environments with heavy data flow, this can impact productivity. To address this, organizations need robust hardware, proper configuration, and network optimization strategies. However, upgrading infrastructure increases costs. Balancing strong security with optimal performance remains a challenge, as overloading the firewall or misconfiguring rules may lead to bottlenecks, service disruptions, or even security gaps if traffic inspection is reduced to improve speed.

  • Complex Configuration and Management

Setting up and maintaining a firewall requires skilled administrators to configure rules, policies, and filters correctly. Misconfigured firewalls may either block legitimate traffic, causing disruptions, or allow malicious traffic, creating security holes. Large organizations with complex networks face challenges in managing multiple firewalls across different locations. Regular updates and monitoring are necessary to keep policies aligned with evolving security threats. Inadequate documentation or improper rule prioritization may result in conflicts and vulnerabilities. To overcome this, organizations must invest in trained professionals, automation tools, and consistent auditing practices to ensure firewalls function effectively without compromising usability or security.

  • Cost and Resource Requirements

While basic firewalls are affordable, advanced solutions like next-generation firewalls (NGFWs) come with high costs for acquisition, deployment, and maintenance. Additionally, they require powerful hardware, constant updates, and skilled IT staff for monitoring. Smaller organizations often struggle with these expenses, making them more vulnerable to cyberattacks. Furthermore, as threats evolve, firewalls need regular upgrades, which add to long-term costs. Cloud-based firewalls may reduce infrastructure expenses but still involve subscription fees. Balancing cost-effectiveness and strong security remains a major challenge, especially for businesses with limited budgets that cannot afford enterprise-grade firewall solutions with advanced threat protection.

E-commerce: Business Models and Concepts

indiafreenotesby indiafreenotes0

E-commerce (electronic commerce) refers to the buying and selling of goods and services over the internet. With the rapid growth of technology and internet connectivity, e-commerce has transformed business operations, customer behavior, and market dynamics. There are various business models and concepts that define the structure and functioning of e-commerce.

E-commerce Business Models:

  • Business to Consumer (B2C):

B2C model is one of the most commonly known e-commerce models. It refers to transactions between businesses and individual consumers. Online retailing is the most popular form of B2C commerce. Companies such as Amazon, Alibaba, and Walmart operate in this space, where consumers purchase products or services from businesses directly via websites or mobile apps. In B2C, the transaction process involves browsing, ordering, payment, and delivery, with a focus on providing a user-friendly shopping experience.

  • Business to Business (B2B):

B2B e-commerce involves transactions between two or more businesses. These transactions often include wholesale trade, raw materials, or bulk product purchases. The buyers are typically other companies, rather than individual consumers. Platforms such as Alibaba, ThomasNet, and Indiamart serve as intermediaries for B2B transactions. This model is more complex compared to B2C due to the larger scale of transactions, longer sales cycles, and the need for more robust systems to manage relationships, orders, and logistics.

  • Consumer to Consumer (C2C):

C2C e-commerce refers to transactions between consumers, often facilitated by a third-party platform. Online marketplaces such as eBay, Craigslist, and Poshmark serve as intermediaries, allowing individuals to buy and sell goods or services to one another. The C2C model benefits from low overhead costs as it typically involves no large inventory or physical stores. It’s highly popular for second-hand goods, auctioned items, and peer-to-peer services.

  • Consumer to Business (C2B):

C2B is a less common but growing model where individual consumers offer products or services to businesses. This model has evolved with the rise of freelance work, crowdsourcing, and influencers. Websites like Fiverr, Upwork, and Shutterstock facilitate these transactions by allowing individuals to sell their skills, content, or products to businesses. This model highlights how consumers can generate value for businesses, especially in the context of creative services or product feedback.

  • Business to Government (B2G):

In this model, businesses provide goods and services to governments or government agencies. B2G transactions typically involve government contracts for procurement, consulting, and other services. E-commerce platforms that facilitate B2G exchanges often require complex bidding processes and compliance with governmental regulations. Examples of B2G platforms include government procurement websites and e-tendering portals.

  • Subscription-Based E-commerce:

The subscription model has gained immense popularity, especially in digital content and software services. Under this model, consumers pay a recurring fee for access to products or services over a specified period. Netflix, Spotify, and Amazon Prime are some of the most recognized subscription-based services. Subscription e-commerce also extends to physical goods, such as beauty boxes (e.g., Ipsy), meal kits (e.g., Blue Apron), and even pet supplies (e.g., BarkBox).

  • Marketplace Model:

In a marketplace business model, the platform owner (like Amazon, Etsy, or eBay) acts as an intermediary between sellers and buyers, facilitating transactions without directly selling products. The platform typically charges a fee or commission on each sale. The marketplace model offers businesses the opportunity to reach a larger audience while consumers benefit from a variety of choices and competitive pricing. This model emphasizes scalability, where the platform owner earns revenue without needing to maintain inventory.

Concepts in E-commerce:

  • Digital Payment Systems:

A core aspect of e-commerce is the ability to conduct secure online transactions. Payment gateways such as PayPal, Stripe, and credit card processors facilitate online payments by providing a secure method for transferring money. Digital wallets like Apple Pay and Google Pay have simplified the payment process for consumers, enabling faster transactions with minimal friction.

  • Online Security and Privacy:

With the increasing prevalence of e-commerce, ensuring the safety of consumer data is crucial. Security protocols like Secure Sockets Layer (SSL) and encryption technologies protect sensitive data during online transactions. Additionally, privacy concerns have led to stricter regulations such as the General Data Protection Regulation (GDPR) in Europe, ensuring businesses handle customer data responsibly.

  • Logistics and Supply Chain Management:

Efficient logistics and supply chain management are essential for e-commerce businesses to ensure timely delivery of products. Companies must invest in warehousing, inventory management, and shipping systems to meet consumer expectations. Technologies like dropshipping and fulfillment by Amazon (FBA) have simplified supply chain processes, allowing businesses to focus on sales and customer experience.

  • Customer Relationship Management (CRM):

Successful e-commerce businesses emphasize customer engagement and retention. CRM tools and software help companies track customer interactions, personalize marketing efforts, and improve customer service. Through customer data, businesses can better understand preferences and behavior, enabling tailored marketing campaigns and more efficient sales strategies.

  • Digital Marketing:

E-commerce businesses rely heavily on digital marketing strategies to attract and retain customers. Search Engine Optimization (SEO), Pay-Per-Click (PPC) advertising, email marketing, and social media engagement are some of the common tactics used. Social proof, such as customer reviews and influencer endorsements, plays a critical role in influencing purchasing decisions in the online marketplace.

  • Mobile Commerce (M-commerce):

Mobile commerce, or m-commerce, is another important concept in e-commerce. With the rise of smartphones and mobile apps, many consumers now shop on-the-go. Optimizing websites for mobile devices and creating user-friendly mobile apps are critical strategies for businesses to cater to mobile shoppers. Features like push notifications and location-based promotions also contribute to enhancing the mobile shopping experience.

Patent

indiafreenotesby indiafreenotes1

A patent is a form of intellectual property that gives the owner the legal right to exclude others from making, using, selling and importing an invention for a limited period of years, in exchange for publishing an enabling public disclosure of the invention. In most countries patent rights fall under civil law and the patent holder needs to sue someone infringing the patent in order to enforce his or her rights. In some industries patents are an essential form of competitive advantage; in others they are irrelevant.

The procedure for granting patents, requirements placed on the patentee, and the extent of the exclusive rights vary widely between countries according to national laws and international agreements. Typically, however, a patent application must include one or more claims that define the invention. A patent may include many claims, each of which defines a specific property right. These claims must meet relevant patentability requirements, such as novelty, usefulness, and non-obviousness.

Under the World Trade Organization’s (WTO) TRIPS Agreement, patents should be available in WTO member states for any invention, in all fields of technology, provided they are new, involve an inventive step, and are capable of industrial application. Nevertheless, there are variations on what is patentable subject matter from country to country, also among WTO member states. TRIPS also provides that the term of protection available should be a minimum of twenty years.

The word patent originates from the Latin patere, which means “to lay open” (i.e., to make available for public inspection). It is a shortened version of the term letters patent, which was an open document or instrument issued by a monarch or government granting exclusive rights to a person, predating the modern patent system. Similar grants included land patents, which were land grants by early state governments in the USA, and printing patents, a precursor of modern copyright.

In modern usage, the term patent usually refers to the right granted to anyone who invents something new, useful and non-obvious. Some other types of intellectual property rights are also called patents in some jurisdictions: industrial design rights are called design patents in the US, plant breeders’ rights are sometimes called plant patents, and utility models and Gebrauchsmuster are sometimes called petty patents or innovation patents.

The additional qualification utility patent is sometimes used (primarily in the US) to distinguish the primary meaning from these other types of patents. Particular species of patents for inventions include biological patents, business method patents, chemical patents and software patents.

  • Patentable

To qualify for a patent, the invention must meet three basic tests. First, it must be novel, meaning that the invention did not previously exist. Second, the invention must be non-obvious, which means that the invention must be a significant improvement to existing technology. Simple changes to previously known devices do not comprise a patentable invention. Finally, the proposed invention must be useful. Legal experts commonly interpret this to mean that no patent will be granted for inventions that can only be used for an illegal or immoral purpose.

Some types of discoveries are not patentable. No one can obtain a patent on a law of nature or a scientific principle even if he or she is the first one to discover it. For example, Isaac Newton could not have obtained a patent on the laws of gravity, and Albert Einstein could not have patented his formula for relativity, E=mc2.

Under the law of the European Patent Convention (EPC), patents are only granted for inventions which are capable of industrial application, which are new and which involve an inventive step. An invention may be defined as a proposal for the practical implementation of an idea for solving a technical problem. An invention is capable of industrial application if it can be made or used in any kind of industry, including agriculture, as distinct from purely intellectual or aesthetic activity.

An invention is said to be new if, prior to the date of filing or to the priority date accorded to the application from an earlier application for the same invention, it was not already known to the public in any form (written, oral or through use), ie it did not form part of the state of the art. An invention is said to involve an inventive step if, in the light of what is already known to the public, it is not obvious to a so-called skilled person, i.e someone with good knowledge and experience of the field.

Under the Indian patent law a patent can be obtained only for an invention which is new and useful. The invention must relate to a machine, article or substance produced by manufacture, or the process of manufacture of an article. A patent may also be obtained for an improvement of an article or of a process of manufacture. In regard to medicine or drug and certain classes of chemicals no patent is granted for the substance itself even if new, but a process of manufacturing and substance is patentable. The application for a patent must be true and the first inventor or the person who has derived title from him, the right to apply for a patent being assignable.

  • Non Patentable

Some inventions cannot be patented. Under the law of the European Patent Convention (EPC) the list of non-patentable subject-matter includes methods of medical treatment or diagnosis, and new plant or animal varieties. Further information on such fields can be obtained from a patent attorney. Nor may patents be granted for inventions whose exploitation would be contrary to public order or morality (obvious examples being land-mines or letter-bombs).The following are not regarded as inventions: discoveries; scientific theories and mathematical methods; aesthetic creations, such as works of art or literature; schemes, rules and methods for performing mental acts, playing games or doing business; presentations of information; computer software.

Under the Indian law the following are non patentable (as mentioned under section 3 and 5 of Indian Patents Act, 1970):

An invention which is frivolous or which claims anything obvious contrary to well established natural laws. An invention the primary or intended use of which would be contrary to law or morality or injurious to public heath. The mere discovery of a scientific principle or the formulation of an abstract theory.

The mere discovery of any new property or new use for a known substance or of the mere use of a known process, machine or apparatus unless such known process results in a new product or employs at least one new reactant.

A substance obtained by a mere admixture resulting only in the aggregation of the properties of the components thereof or a process for producing such substance The mere arrangement or re-arrangement or duplication of known devices each functioning independently of one another in a known way. A method or a process of testing applicable during the process of manufacture for rendering the machine, apparatus or other equipment more efficient or for the improvement or restoration of the existing machine, apparatus or other equipment or for the improvement or control of manufacture.

A method of agriculture or horticulture. Any process for the medicinal, surgical, curative, prophylactic or other treatment of human being or any process for a similar treatment of animals or plants to render them free of disease or to increase their economic value or that of their products.

No Patent shall be granted in respect of an invention relating to Atomic energy. Claiming substances intended for use, or capable of being used, as food or as medicine or drug Relating to substance prepared or produced by chemical processes (including Alloys, optical glass, semiconductor and inter-metallic compounds), no patent shall be granted in respect of claims for the substances themselves, but claims for the methods or processes of manufacture shall be patentable. The criteria under the US laws are also quite similar as above. Books, movies, and works of art cannot be patented, but protection is available for such items under the law of copyright.

  • Rights in a Patent

Patent registrations confers on the rightful owner a right capable of protection under the Act i.e. the right to exclude others from using the invention for a limited period of time. The monopoly over patented right can be exercised by the owner for a period of 20 years after which it is open to exploitation by others.

Patent confers the right to manufacture, use, offer for sale, sell or import the invention for the prescribed period.

Time Period for which Patent is granted:

Initially, the Act provided for a shorter term pf protection for medicine or drug substances. However, vide the Amendment Act of 2005 uniform period of 20 years was provided for all the Patents. Thus, once the prescribed period of 20 years is over, then any person can exploit the patented invention. Here it would be relevant to mention that similar to a trademark even the term of a patent begins from the date of application of patent.

Requirements for Grant of Patent:

  1. The application for Patent shall be made at the Indian Patent Office.
  2. Any person i.e. Indian or a Foreigner, individual, company or the Government can file a Patent Application.
  • The person applying for Patent shall be the true and first inventor of the invention proposed to be patented.
  1. The patent application can also be made jointly.
  2. The patent application shall primarily disclose the best method of performing the invention known to the applicant for which he is entitled to claim protection.
  3. The applicant shall also define the scope of invention.
  • The invention desired to be patented shall be- new, should involve an inventive step and must be capable of industrial application.
  • A patent application can be made for a single invention only.
  1. An international application made under the PCT (Patent Co-operation Treaty) designating India shall be deemed as an application made under the Patents Act with the priority date accruing from the date of the international filing date accorded under the PCT.

Invention under the Patent Act:

The Act under Section 2(1)(j) defines “invention” as a new product or process involving an inventive step capable of industrial application.

The term “industrial application” refers to capable of industrial application in relation to an invention means that the invention is capable of being made or used in an industry. One of the pre-requisite of invention is that it should be new i.e. the invention proposed to be patented has not been in the public domain or that it does not form part of the state of the art.

Under the Patent Act, both processes and products are entitled to qualify as inventions if they are new, involve an inventive step and are capable of industrial application.

Requirements to Qualify as Invention:

  1. The Invention must be new
  2. Invention must involve an inventive step
  • The invention must be capable of industrial application or utility;
  1. The invention shouldn’t come under the inventions which are not patentable under Section 3 and 4 of the Patent Act, 1970;

Non-patentable inventions are enumerated under Section 3 and 4 of the Patent Act. Such inventions are delineated below:

  • Any Invention which is frivolous or which claims anything obviously contrary to well established natural laws is not patentable.
  • Inventions which are contrary to public order or morality is not patentable.
  • An idea or discovery cannot be a subject matter of a patent application.
  • Inventions pertaining to known substances and known processes are not patentable i.e. mere discovery of a new form of a known substance which does not enhance the known efficacy of that substance is not patentable.
  • An invention obtained through a mere admixture or arrangement is not patentable.
  • A method of agriculture or horticulture cannot be subject matter of patent.
  • A process involving medical treatment of human and animals or to increase their economic value cannot be subject matter of a patent.
  • Plants and animals in whole or in part are not patentable.
  • A mathematical or business method or a computer program per se or algorithms is excluded from patent protection.
  • Matters that are subject matter of copyright protection like literary, dramatic, musical or artistic work is not patentable.
  • Any scheme or rule.
  • Presentation of information
  • Topography of integrated circuits.
  • Traditional knowledge.
  • Inventions relating to atomic energy.

Infringement of Patent:

Infringement of Patent primarily refers to intrusion or violation of the rights of a Patentee against which the Patentee has statutory rights under the Act.

The factors that are essential in determining infringement of a Patent are as under:

  1. While determining infringement it has to be assessed whether the infringing activity fell within the scope of the invention. Thus, the infringement has to be determined with regard to what has been claimed as invention under the Patent Act by applying the principles or standards of construction.
  2. To determine whether the infringing activity violated any statutory rights conferred to the Patentee under the Act. In this respect reference can be made to Section 48 of the Act which enumerates the rights of the Patentee with respect to a product patent and process patent.
  3. To determine the infringer i.e. the person liable for the infringement.
  4. To determine whether the infringing act fell within the acts which do not amount to infringement under the Patents Act i.e. excluded acts of Government use, use of patented product or process for experiment or research, import of medicine or drug by Government and patents in foreign vessels and aircrafts.

Key differences between Traditional Commerce and E- Commerce

indiafreenotesby indiafreenotes2

Traditional Commerce refers to the conventional method of buying and selling goods and services through physical, face-to-face transactions. In this system, businesses operate through brick-and-mortar stores, shops, or marketplaces, where customers can inspect, touch, and try products before purchasing. Transactions are typically conducted using cash, cheques, or other offline payment methods. Traditional commerce relies on local or regional markets, personal interactions, and established trade relationships. While it provides a personal shopping experience and immediate product availability, it is limited by geography, time, and scale. Despite the growth of e-commerce, traditional commerce remains important for goods requiring physical inspection.

Features of Traditional Commerce:

  • Physical Presence

Traditional commerce requires a physical location where buyers and sellers interact directly. Shops, stores, markets, or showrooms serve as venues for conducting transactions. Customers can physically examine products, assess quality, and make informed purchasing decisions. This face-to-face interaction builds trust and provides immediate feedback. The physical presence also allows businesses to display merchandise attractively, engage with customers personally, and offer on-the-spot services. However, this feature limits market reach to local or regional areas and requires higher operational costs for maintaining physical infrastructure, staffing, and utilities.

  • Face-to-Face Transactions

A defining feature of traditional commerce is direct interaction between buyers and sellers. Customers can negotiate prices, ask questions, and clarify doubts before making a purchase. Sellers can provide personalized advice and build relationships through communication, creating loyalty and trust. This immediate interaction reduces misunderstandings regarding product quality, specifications, or pricing. Face-to-face transactions also allow businesses to offer instant problem resolution, refunds, or exchanges. While this fosters a strong personal connection, it limits the speed and scalability of business compared to digital methods, as each transaction depends on physical presence and direct communication.

  • Limited Market Reach

Traditional commerce is primarily restricted by geographical boundaries. Businesses can attract customers mainly from the local community or nearby regions. Expansion requires opening additional physical outlets, which increases costs and logistical challenges. Unlike e-commerce, products and services cannot be marketed globally without physical infrastructure. This limitation affects revenue potential and scalability. Customers also have fewer options compared to online platforms, reducing competition. Despite these restrictions, traditional commerce benefits from personal trust, loyalty, and immediate product availability. Local marketing strategies, word-of-mouth promotion, and community engagement are critical to sustaining a traditional business within its limited market.

  • Dependence on Operating Hours

Traditional commerce operates within fixed business hours, restricting when customers can make purchases. Stores and markets open and close at specific times, limiting accessibility compared to 24/7 online platforms. Holidays, weekends, and local regulations further influence operational hours. Customers must plan visits, which can be inconvenient for busy individuals. Businesses also need staff to manage operations during these hours, increasing labor costs. While this allows controlled management of operations, it reduces flexibility and limits sales opportunities. In contrast, e-commerce provides round-the-clock access, catering to customers’ schedules and maximizing revenue potential without time constraints.

  • Cash-Based Transactions

Traditional commerce predominantly relies on cash or offline payment methods, including cheques, money orders, or debit/credit cards in physical stores. Transactions are immediate and tangible, which simplifies record-keeping for small businesses. This feature reduces dependence on digital infrastructure but may pose risks such as theft, counterfeit currency, or errors in manual bookkeeping. Cash transactions require physical handling and banking processes, which can be time-consuming. Unlike e-commerce, which offers multiple digital payment options, traditional commerce is limited in convenience and speed of financial transactions. Nonetheless, cash-based dealings are trusted by many customers, especially in areas with low digital penetration.

  • Personal Customer Service

Traditional commerce emphasizes direct, personal service, enhancing the shopping experience. Sellers can guide customers, recommend products, and resolve queries instantly. Personal attention builds strong relationships, loyalty, and customer satisfaction. Businesses can tailor services based on individual preferences, ensuring a customized experience. This personal touch is particularly valuable for products requiring demonstration, fitting, or explanation. However, providing consistent service requires trained staff and adequate resources. While this feature fosters trust and repeat business, it limits scalability, as businesses can only serve as many customers as physical space and staff allow.

E-Commerce

E-Commerce (Electronic Commerce) refers to the buying and selling of goods and services over the internet. It enables businesses and consumers to conduct transactions digitally without relying on physical stores. E-commerce includes various models such as B2B (business-to-business), B2C (business-to-consumer), C2C (consumer-to-consumer), and C2B (consumer-to-business). It relies on technologies like secure online payments, digital marketing, and web or mobile platforms to provide convenience, speed, and broader market access. E-commerce allows 24/7 shopping, personalized experiences, global reach, and cost efficiency, transforming traditional trade and making commerce faster, more accessible, and highly scalable.

Type of Databases

indiafreenotesby indiafreenotes1

Databases are structured collections of data used to store, retrieve, and manage information efficiently. They are essential in modern computing, supporting applications in business, healthcare, finance, and more. Different types of databases cater to various needs, ranging from structured tabular data to unstructured multimedia content.

  • Relational Database (RDBMS)

Relational Database stores data in structured tables with predefined relationships between them. Each table consists of rows (records) and columns (attributes), and data is accessed using Structured Query Language (SQL). Relational databases ensure data integrity, normalization, and consistency, making them ideal for applications requiring structured data storage, such as banking, inventory management, and enterprise resource planning (ERP) systems. Popular relational databases include MySQL, PostgreSQL, Microsoft SQL Server, and Oracle Database. However, they may struggle with handling unstructured or semi-structured data, requiring additional tools for scalability and performance optimization.

  • NoSQL Database

NoSQL (Not Only SQL) databases are designed for scalability and flexibility, handling unstructured and semi-structured data. NoSQL databases do not use fixed schemas or tables; instead, they follow different data models such as key-value stores, document stores, column-family stores, and graph databases. These databases are widely used in big data applications, real-time analytics, social media platforms, and IoT. Popular NoSQL databases include MongoDB (document-based), Cassandra (column-family), Redis (key-value), and Neo4j (graph-based). They offer high availability and horizontal scalability but may lack ACID (Atomicity, Consistency, Isolation, Durability) compliance found in relational databases.

  • Hierarchical Database

Hierarchical Database organizes data in a tree-like structure, where each record has a parent-child relationship. This model is efficient for fast data retrieval but can be rigid due to its strict hierarchy. Commonly used in legacy systems, telecommunications, and geographical information systems (GIS), hierarchical databases work well when data relationships are well-defined. IBM’s Information Management System (IMS) is a well-known hierarchical database. However, its inflexibility and difficulty in modifying hierarchical structures make it less suitable for modern, dynamic applications. Navigating complex relationships in hierarchical models can be challenging, requiring specific querying techniques like XPath in XML databases.

  • Network Database

Network Database extends the hierarchical model by allowing multiple parent-child relationships, forming a graph-like structure. This improves flexibility by enabling many-to-many relationships between records. Network databases are used in supply chain management, airline reservation systems, and financial record-keeping. The CODASYL (Conference on Data Systems Languages) database model is a well-known implementation. While faster than relational databases in certain scenarios, network databases require complex navigation methods like pointers and set relationships. Modern graph databases, such as Neo4j, have largely replaced traditional network databases, offering better querying capabilities using graph traversal algorithms.

  • Object-Oriented Database (OODBMS)

An Object-Oriented Database (OODBMS) integrates database capabilities with object-oriented programming (OOP) principles, allowing data to be stored as objects. This model is ideal for applications that use complex data types, multimedia files, and real-world objects, such as computer-aided design (CAD), engineering simulations, and AI-driven applications. Unlike relational databases, OODBMS supports inheritance, encapsulation, and polymorphism, making it more aligned with modern programming paradigms. Popular object-oriented databases include db4o and ObjectDB. However, OODBMS adoption is lower due to its complexity, lack of standardization, and limited compatibility with SQL-based systems.

  • Graph Database

Graph Database is designed to handle data with complex relationships using nodes (entities) and edges (connections). Unlike traditional relational databases, graph databases efficiently represent and query interconnected data, making them ideal for social networks, fraud detection, recommendation engines, and knowledge graphs. Neo4j, Amazon Neptune, and ArangoDB are popular graph databases that support graph traversal algorithms like Dijkstra’s shortest path. They excel at handling dynamic and interconnected datasets but may require specialized query languages like Cypher instead of standard SQL. Their scalability depends on graph size, and managing large graphs can be computationally expensive.

  • Time-Series Database

Time-Series Database (TSDB) is optimized for storing and analyzing time-stamped data, such as sensor readings, financial market data, and IoT device logs. Unlike relational databases, TSDBs efficiently handle high-ingestion rates and time-based queries, enabling real-time analytics and anomaly detection. Popular time-series databases include InfluxDB, TimescaleDB, and OpenTSDB. They offer fast retrieval of historical data, downsampling, and efficient indexing mechanisms. However, their focus on time-stamped data limits their use in general-purpose applications. They are widely used in stock market analysis, predictive maintenance, climate monitoring, and healthcare (e.g., ECG data storage and analysis).

  • Cloud Database

Cloud Database is hosted on a cloud computing platform, offering on-demand scalability, high availability, and managed infrastructure. Cloud databases eliminate the need for on-premise hardware, reducing maintenance costs and operational complexity. They can be relational (SQL-based) or NoSQL-based, depending on the application’s needs. Examples include Amazon RDS (Relational), Google Cloud Spanner (Hybrid SQL-NoSQL), and Firebase (NoSQL Document Store). Cloud databases enable global accessibility, automated backups, and seamless integration with AI and analytics tools. However, concerns about data security, vendor lock-in, and latency exist, especially when handling sensitive enterprise data.
