About this template

What is this template?

This is a statutory filing for the Indian Patent Office and not a private contract. It contains specific fields for declaring the nature of the claim under Section 20 of the Patents Act 1970 and requires details of the instrument or agreement creating the interest.

When should you use it?

Use this form when the ownership of a pending patent application changes due to death or contract. Use a Transfer of Ownership or Assignment Agreement to document the underlying transaction before filing this form.

Who it's for

  • a person claiming a share in a patent application through an assignment or agreement
  • the legal representative of a deceased patent applicant
  • an applicant requesting a name change due to corporate restructuring before grant
