What amounts to Infringement of Patent?

In India, the provisions relating to infringement of patents are governed by the Indian Patents Act of 1970. The Act fails list to list what activities constitute infringement under the Act, however, a violation of any exclusive rights given to the patent holder by any person without the permission of the patent holder would constitute infringement under the Act. This article in brief describes the acts that constitute infringing acts and certain acts that do not.

A patent is an invention registered under the Indian Patents Act, 1970 which gives the holder of a patent the exclusive right to prohibit/restrain any person from manufacturing, distributing, or selling such invention as more particularly mentioned in Section 48 of the Act. Commission of any such act by any person without the permission of the patent holder shall deem to be an infringement of the said patent.

What amounts to infringement under the Act?

The Patent Act does not specify the instances in which infringement would occur, however under Section 48 of the Act lists down 2 kinds of activities which, if done without the consent of the patent holder, would amount to infringement under the Act, namely:

  • Making, selling, using, offering for sale or importing the patented product; or
  • Using the patented process or selling, using, offering for sale, or importing any product directly obtained from such patented products.

In other words, if any person without the consent of the patent holder, uses, sells, imports, or offers to sell any patented product or process, then such action would constitute infringement under the provisions of the Act.

In Novartis AG and Another vs. Cipla Limited (I.A. No.24863/2014 IN CS(OS) 3812/2014), the Delhi High Court held that the act of making and selling a generic copy of the Plaintiff’s drug amounted to infringement and granted an injunction restricting Cipla from making and selling such generic copy of the Plaintiff’s patented drug.

In this case, Novartis had filed a suit against Cipla seeking damages for infringement of its patents covering Onbrez (an indacaterol-drug used to treat chronic obstructive pulmonary disease) before the Delhi High Court.

1. Use by the Government:
