Intellectual property protection is crucial in promoting innovation and creativity in India. Patents are an essential aspect of intellectual property rights that provide inventors with exclusive rights to prevent others from making, using, or selling their inventions. However, patent infringement is common in India, and inventors must understand the various defences available to protect their patents. This article will discuss the six most common defences against patent infringement in India.
Prior Use defence
The prior use defence is a defence against patent infringement, which allows the defendant to continue using the invention if they can prove that they had been using it before filing the patent. Under this defence, the defendant must prove that they had been using the invention in good faith and that their use was not secret or confidential.
The prior use defence is available only to those who had been using the invention before the patent filing. Additionally, the prior use must have been in good faith and not to copy or steal the invention. This defence can be tricky to prove, and the burden of proof lies with the defendant.
Independent Creation defence
The independent creation defence is a defence that the defendant can raise if they can prove that they had independently created the invention and that they had no knowledge of the existence of the patent. Under this defence, the defendant must show that their invention was not derived from the patent holder’s invention.
The independent creation defence is available only to those who had created the invention independently of the patent holder. The defendant must also prove that they did not know of the existence of the patent. Proving the independent creation defence can be challenging, and the burden of proof lies with the defendant.
Obviousness defence
The obviousness defence is a defence that the defendant can raise if they can prove that the patent is obvious and lacks novelty. Under this defence, the defendant must show that the invention is not a significant improvement over existing technology and is merely an obvious combination of known elements.
The obviousness defence is available only if the invention is deemed to be obvious and lacks novelty. The defendant must provide evidence to support their claim that the invention is obvious. The burden of proof lies with the defendant; proving this defence can be challenging.
Non-Infringement defence
The non-infringement defence is a defence that the defendant can raise if they can prove that their product or service does not infringe on any of the patent holder’s exclusive rights. Under this defence, the defendant must show that their product or service does not fall within the scope of the patent claims.
The non-infringement defence is available only if the defendant can prove that their product or service does not fall within the scope of the patent claims. The burden of proof lies with the defendant; proving this defence can be challenging.
Experimental Use defence
The experimental use defence is a defence that the defendant can raise if they can prove that they had been using the invention for experimentation or research purposes only. Under this defence, the defendant must show that their use of the invention was not for commercial purposes and that it was necessary for experimentation or research.
The experimental use defence is available only if the defendant can prove that their use of the invention was for experimentation or research purposes only and not for commercial purposes. The burden of proof lies with the defendant; proving this defence can be challenging.
Invalidity defence
The invalidity defence is a defence that the defendant can raise if they can prove that the patent is invalid. Under this defence, the defendant must show that the patent does not meet the legal requirements for patentability, such as novelty, non-obviousness, and industrial applicability.
The invalidity defence is available only if the defendant can provide evidence to support their claim that the patent is invalid. The burden of proof lies with the defendant, and proving this defence can be challenging.
