About this template

What is this template?

This document is a formal deed for the permanent transfer of patent rights in India. It contains specific warranties regarding the patent being free from encumbrances and includes a schedule to describe the patented article. It is not a licensing agreement, as it transfers absolute ownership rather than granting a temporary right to use.

When should you use it?

Use this document when a partnership is transferring its business and intellectual property to a corporate entity and needs to comply with the Patents Act 1970. If you only want to grant someone permission to use the patent while retaining ownership, use a Patent License Agreement instead.

Templates in our curated library are professionally drafted for US or UK law. The wider library comes from the GitLaw community and public sources - a solid starting point, but check any template fits your situation before you rely on it.

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.

Yes. Upload a Word, PDF, or Markdown file and GitLaw will open it in the editor. You can review, edit, or chat with GitLaw about it the same way you would with any template from the library.
