  2. An application for registration of such document should be filed in the prescribed manner in Form-16 within the time prescribed under section 68. The document when registered will have effect from the date of execution.

Why and where is this patent agreement necessary?

A patent is important because it helps to safeguard your invention. It protects any product design that meets a certain identification according to its originality, practicality, suitability, and utility. The patent owner has the right to stop others from commercially utilizing the patented invention. A patent contract can protect an invention for 20 years. This time period starts as you file a patent application. Patent protection means that the invention cannot be commercially made, used, imported and sold by others without the patent owner’s consent. Only the owner of a patent has the complete right to utilize its value to the exclusion of all other parties. Therefore, protecting ownership of a patent and its accompanying rights can be very important to a company. A patent license agreement typically gives an assignee exclusive right to manufacture, sell, and use a patented invention, subject to terms and conditions. A patent license agreement will also define the number of royalties the assignee owes the assignor.

Forms/Nature of Transfer of Patent Rights:

Grant of a Patent confers to a patentee the right to prevent others from making, using, exercising or selling the invention without his permission. The following are the ways in which a patentee can deal with the patent:

  1. Assignment
  2. Licenses
  3. Transmission of patent by operation of law

1. Assignment

The term ‘assignment’ is not defined in the Indian Patents Act. Assignment is an act by which the patentee assigns whole or part of his patent rights to the assignee who acquires the right to prevent others from making, using, exercising or vending the invention. There are three kinds of assignments

  • Legal Assignment
  • Equitable Assignment
  • Mortgage

2. Licenses:

The Patents Act allows a patentee to grant a License by the way of agreement under section 70 of the Act. A patentee by the way of granting a license may permit a licensee to make, use, or exercise the invention. A license granted is not valid unless it is in writing. The license is contract signed by the licensor and the licensee in writing and the terms agreed upon by them including the payment of royalties at a rate mentioned for all articles made under the patent. Licenses are of the following types,

  • Voluntary License
  • Statutory License(such as compulsory License)
  • Exclusive/Limited License
  • Express/Implied License

3. Transmission of Patent by Operation of law

When a patentee dies, his interest in the patent passes to his legal representative; in case of dissolution or winding up of a company or bankruptcy transmission of patent by operation of law occurs.
