Patent Assignment Agreement in India – Legal Framework & Fees
Patent Assignment in India refers to the transfer of ownership rights in a patent or a part-interest in a patent from one party to another. Although the term “patent assignment” is not expressly defined in the Indian Patent Act, 1970, the Act and Rules mandate that any assignment — whether transferring full ownership, a share, mortgage, or other interests — must be effected through a written deed executed between the parties. The deed of assignment must clearly set out the rights and obligations of the assignor and assignee and be documented properly for legal validity.
Once executed, the deed of assignment and supporting evidence of title must be registered with the Indian Patent Office by filing Form-16 with the Controller General of Patents, Designs and Trademarks (CGPDTM). Upon satisfactory proof of title, the Controller will record the assignment in the Patent Register.
Registration of Patent Assignment –Steps
- Form-16 Submission
An application in Form-16 is filed with the Indian Patent Office to record the assignment or transfer of patent rights.
- Deed of Assignment
A properly drafted deed of assignment executed by the assignor and assignee must accompany the application.
- Title Evidence
Documents evidencing transfer, sale, assignment, or any change affecting patent proprietary rights should be enclosed.
- Copies of Assignment Deed
Two copies of the signed assignment deed are typically submitted along with Form-16.
Official Fees for Patent Assignment in India
The official fee for recording a patent assignment in India varies depending on the category of the applicant filing the Form-16, as prescribed under the First Schedule of the Patent Rules:
| Applicant Category | E-filing Fee per Patent | Physical Filing Fee per Patent |
| Natural person(s)/Startup(s) | ₹1,600 | ₹1,750 |
| Small entity (alone or with natural person/startup) | ₹4,000 | ₹4,400 |
| Other entities (including large companies) | ₹8,000 | ₹8,800 |
Note: These statutory fees relate solely to the Government charges payable for recording the assignment. Professional fees, drafting costs, and legal advisory charges, if engaged, are additional and separate.
Importance of Patent Assignment Registration
Recording an assignment with the Patent Office is crucial for ensuring:
- Legal recognition of ownership over patent rights
- Public notice of title affecting enforceability and licensing
- Clear chain of title for due diligence in investments and transactions
- Protection against disputes relating to proprietary rights
Such formal registration enables startups, MSMEs, and global businesses to manage intellectual property reliably — whether for commercialisation, licensing, mergers, or strategic partnerships.
Documents Typically Required
To effect a patent assignment recordal, the following are generally submitted:
- Completed Form-16 for recording the assignment
- The deed of assignment duly executed
- Evidence of transfer/sale/assignment affecting the patent title
- Copies of supporting documents proving rights, transfer, or assignment
Ensuring accuracy and completeness is important to avoid delays or queries from the Patent Office during recordal.
