About this template

What is this template?

This is a formal filing for the Indian Patent Office used specifically to request changes to patent records. It contains sections for the nature of the amendment and reasons for the request. It is not a petition for restoration or a notice of opposition.

When should you use it?

Use this form when you need to change a filed specification or correct an error in the Register of Patents in India. Use Form 13 instead for amendments made after the patent has been granted if the specific change is for a different purpose.

Who it's for

  • an inventor seeking to correct a clerical error in a pending Indian patent application
  • a patent owner updating the name or address on an existing Indian patent grant
  • a patent applicant requesting a substantive amendment to a complete specification in India

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.
