About this template

What is this template?

This is a statutory filing used by the Indian Patent Office to process formal changes to patent records. It is not an agreement between parties but a petition to a regulator that must include a declaration regarding the absence of litigation. It specifically requires a highlighted copy of the proposed changes to be annexed to the filing.

When should you use it?

Use this form when you need to modify a patent application or specification already on file with the Indian authorities. Use Form 1 instead if you are making the initial application for a patent.
