What Is Patent Assignment?
A quick, plain-language explanation before the details.
A patent assignment is the legal transfer of ownership of a patent (or a patent application) from one party to another, done through a written assignment deed and then recorded with the Patent Office.
Under Sections 68–69 of the Patents Act, 1970, an assignment, mortgage, licence or the creation of any interest in a patent is valid only if it is in writing, reduced to a document embodying all the terms and conditions, and duly executed. The person becoming entitled must apply to have the transaction recorded in the register of patents; until then the document is generally not admitted as evidence of title.
Recorded by the Office of the Controller General of Patents, Designs & Trade Marks (CGPDTM) through the Indian Patent Office, via the e-filing portal at ipindia.gov.in using Form 16.
Once recorded, the assignee's title continues for the remaining term of the patent — up to 20 years from the original date of filing, subject to payment of annual renewal (annuity) fees.

Talk to an Expert →Why Record a Patent Assignment?
An assignment is only as strong as its paperwork and its recordal. Here is why owners and buyers formalise and register the transfer.
-
01
Transfer Ownership Cleanly
A written, executed assignment deed transfers all rights in the patent or application to the assignee, with the scope, consideration and terms clearly set out.
-
02
Title Valid Against Third Parties
Recording the assignment in the register of patents (Form 16) makes the assignee the recognised proprietor — until recorded, the transfer is generally not valid against third parties.
-
03
Admissible as Evidence
An unrecorded assignment is generally not admitted as evidence of title in court. Recordal protects the assignee's ability to enforce the patent.
-
04
Monetise the Asset
Assignment lets an owner realise value by selling the patent outright; licensing lets the owner earn royalties while keeping ownership.
-
05
Support Deals & Fundraising
Clean, recorded ownership of patents is essential during acquisitions, investment due diligence and technology-transfer deals.
-
06
Cover Transmission by Law
Where a patent passes by inheritance or merger, the same recordal route establishes the new owner's title on the register.

What You’ll Receive
What Documents Are Required to Record a Patent Assignment?
Requirements depend on whether you are recording an assignment, a licence or a transmission by operation of law. Keep clear scans (PDF) of the executed deed and identity proofs ready — everything is collected securely online.
Parties (Assignor & Assignee)
For each party to the transfer- Full name, address & nationality of the assignor and assignee
- Identity proof of both parties
- Applicant / entity type — individual, startup, small entity or others
- Power of authority (Form 26) for the patent agent
Patent Details
The subject of the transfer- Patent number or patent application number
- Title of the invention and current status
- Details of the existing proprietor on the register
- Whether the transfer is full or partial (share)
Assignment / Transmission
The instrument of transfer- Executed assignment deed embodying all terms & consideration
- Licence agreement (if recording a licence instead)
- Proof of transmission — probate, will or succession document (if by inheritance)
- Merger / amalgamation order (if transfer by operation of law)
Writing is mandatory
An assignment is valid only if it is in writing and reduced to a document that embodies all the terms and conditions — an oral or informal transfer will not do.
Record it to protect title
Until the assignment is recorded in the register via Form 16, it is generally not admitted as evidence of title and the assignee's rights are not valid against third parties.
Due execution required
The deed must be duly executed by both the assignor and the assignee, with proper stamping and witnessing, before it is filed for recordal.
Licence & transmission too
A licence or a transmission by operation of law (inheritance or merger) is recorded through the same Form 16 route, with the relevant supporting document.

We’ll identify what your case needs →How Patent Assignment & Recordal Works (Step by Step)
The recordal is filed online through the Indian Patent Office e-filing portal at ipindia.gov.in.
Review the transaction
Confirm the patent details, ownership and the nature of the transfer — assignment, licence or transmission — and what rights pass.
Draft the assignment deed
Prepare a written deed embodying all terms, scope, consideration and conditions, tailored to a full or partial transfer.
Execute the deed
Both parties duly execute the deed with proper stamping and witnessing, so it is ready to be produced before the Controller.
Prepare Form 16
The person becoming entitled prepares the application to record the assignment, licence or transmission in the register of patents.
File with the IPO
File Form 16 with the executed deed and supporting documents on the IPO e-filing portal and obtain the acknowledgement.
Recordal & confirmation
Respond to any objection, and once accepted the transaction is entered in the register — the assignee's title is now recorded.
How Long Does Patent Assignment Take?
| Stage | Expected Time |
|---|---|
| Deed drafting & execution by both parties | Depends on the transaction |
| Filing Form 16 acknowledgement | On filing |
| Examination of the recordal application | Varies with IPO workload |
| Entry in the register of patents | On acceptance |
The assignment itself takes effect between the parties on due execution of the deed; the recordal step establishes the assignee's title on the register. Overall recordal time depends on the IPO workload and how quickly any objection or query is resolved.
