About this template

What is this template?

This is a formal statutory filing used by the Indian Patent Office for substituting the claimant as the rightful patent applicant. It is not an initial patent application or a transfer of ownership deed, but a procedural step following a legal determination of entitlement.

When should you use it?

Use this form when the Controller or a Court has ruled that you are the rightful owner of an invention currently filed by another. Use Form 1 for a standard initial patent application instead.

What's inside

Mostly US and UK law. Some templates use general commercial terms that work across jurisdictions, and many note which law they're written for.

It depends on the situation. Templates work well for routine business agreements. For anything involving significant money, complex IP, employment, or areas you're unsure about, it's worth getting professional advice before you sign. GitLaw provides templates and tools, not legal advice.

Open any template in GitLaw and describe the change you want in the chat — 'make clause 4 mutual' or 'add a 30-day notice period', for example. GitLaw drafts the revised language and shows it as a suggested edit. You accept, reject, or keep editing from there.
