Challenging a Granted Patent in India: Legal Guide

INTRODUCTION:
India is a rapidly developing country, with new inventions occurring every second and hour. Businesses compete with each other in a multi-dimensional form to improve themselves and gain profits. Businesses not just focus on their growth but also keep a watch and pay close attention to their rivals. Businesses focus on the inventions made by their rival to ensure that their consumer market is not lost. In this context, the Patents Act, 1970, plays a major role. The Patents Act provides the opportunity for businesses to rebut and oppose the inventions against them made by their rivals. Patents play a significant role in granting exclusive rights to the inventors, along with fostering technology. Every invention, in this fast-paced and rapidly evolving world, is patented to protect its novelty and to provide rights to the inventor. However, patents often lead and tend to create monopolies. One of the significant tools to strike the balance between protecting innovation and preventing an unjust monopoly is the ability of businesses to challenge patents filed by competitors. This ability ensures that weak, frivolous, or strategically abusive patents do not hinder fair competition. The Patents Act of 1970 governs these challenges by providing a detailed mechanism for opposition and revocation.

PATENT CHALLENGE:
A patent challenge refers to a legal process wherein a third party opposes the validity and enforceability of a patent. These challenges are maintaining the integrity of the patent system in India by preventing frivolous and deceptive patents. Patent challenges serve important functions. Patents often a tend to monopolise the markets by the unjustly restricting a market access. Businesses may challenge such patents to prevent monopolistic practices.
There are often risks of infringement litigation proceedings against businesses that tend to innovate goods or services that are frivolously registered as patents. The Businesses can avoid such litigation by taking pre-emptive and informed decisions on the challenging patents of the competitors. Furthermore, weak and invalid patents can be eradicated from the market, promoting competition and innovation. Patent challenges not just act as a defensive mechanism but can also be used as a proactive tool for ensuring fair competition in the market.

STATUTORY RIGHT TO OPPOSE ANY PATENT:
The Patents Act of 1970 provides a comprehensive structure to challenge patents at various stages. The provisions of the Act not just apply to individuals but also to businesses and proprietors.
Opposition Proceedings: Section 25 of the Patents Act of 1970 provides for a detailed method to challenge patents. These opposition proceedings can be challenged in two forms, one as a pre-grant opposition and the other as a post-grant opposition.
1. Pre-grant opposition: Clause 1 of Section 25 deals with pre-grant opposition, which allows ‘any person’ to oppose a patent application after its publication but before it is granted. The term ‘any person’ includes individuals as well as corporations, which opens up opportunities to businesses to oppose patents of their rivals. It works as an early filter to prevent the grant of invalid and frivolous patents. The grounds include lack of novelty, lack of inventive step, non-patentable subject matter, insufficient disclosure or any wrongful obtaining.

2. Post-grant opposition: Clause 2 of Section 25 deals with post-grant opposition, which allows any ‘interested person’ to raise an opposition within one year of the grant of the patent. The term interested person generally includes competitors, businesses operating in the same field or any entities that are likely to be affected by the patent.

Revocation of Patents:
Section 64 of the Patents Act of 1970 provides for the revocation of patents by the High Court. The revocation can be sought independently before a High Court or as a counterclaim in infringement proceedings. The grounds include lack of novelty, lack of inventive step, non-patentable subject matter, fraud or misrepresentation, insufficient disclosure or failure to disclose information. Any Revocation of patents works as a complete invalidation of the patent, making it unenforceable. Thus, filing a revocation works as a powerful and important tool for businesses to keep a check on the patents of their competitors.

POSSIBLE REASONS TO CHALLENGE THE PATENTS:
Challenging the patents of the competing businesses is not just a business strategy but is a method adopted to prevent the monopolisation of an idea A patent grants exclusive rights to an inventor for a period of 20 years. Such a granttends to monopolise the market. If a non-novel invention, a trivial modification or an An obvious improvement is patented, it would lead to an unjust monopoly. Businesses face challenges in these circumstances to prevent corporations from unfairly dominating the market and to ensure that only genuine investments are protected. Such incidents usually take place in the pharma industry, where patenting a drug formula could monopolise it and affect the drug prices and accessibility. Another reason is the barriers to entering the market. If a competitor holds a patent, other businesses cannot manufacture, sell or use the invention and entry into the market becomes restricted. Such barriers can be invalidated, and businesses can gain freedom to operate. Patent infringement lawsuits often lead to heavy damages, injunctions, and loss of reputation. Businesses often challenge as a defensive strategy that is legal as per Section 107 of the Patents Act of 1970.

CONCLUSION:
To conclude, businesses challenge rival patents to ensure fair competition, reduce litigation costs and let freedom to operate within the market. These challenges by businesses act as preventive measures to prevent unjust monopolies, curtail evergreening practices and promote genuine innovation. The mechanisms provided under the Patents Act of 1950, which include opposition and revocation, allow businesses to challenge invalid patents filed by competitors at various stages of registration. These challenges not just serve as business strategies, but they also uphold public interest by improving access to essential products. Patent challenges are a vital component of a well-balanced intellectual property system, which fosters innovation while maintaining fairness and competition.
