How to Sell or Transfer Your Patent Rights in India (Step-by-Step)

A patent, as a form of intellectual property, is a valuable asset. It grants its owner a legal monopoly to an invention for a specified period, typically 20 years. This exclusivity can be a significant source of revenue, but its full potential is often unlocked through commercialization. In India, a patentee can transfer their rights to another party in one of two principal ways: by outright sale (assignment) or by granting a temporary right to use (licensing).

This article provides a comprehensive, step-by-step guide to the legal and procedural requirements for selling or transferring patent rights in India, as governed by the Patents Act, 1970, and related rules.

Understanding the Forms of Patent Transfer

Before embarking on the transfer process, it is crucial to understand the distinction between the two primary methods: assignment and licensing.

• Patent Assignment: This is a permanent and complete transfer of ownership. When a patent is assigned, the original patentee (the assignor) sells all their rights, title, and interest in the patent to another party (the assignee). The assignee then becomes the new proprietor of the patent and is entitled to all the rights and responsibilities that come with it. An assignment can be a full legal assignment or an equitable one, where a party agrees to share ownership. It can also be done through a mortgage, where rights are transferred as security for a loan.

• Patent Licensing: This is a temporary transfer of a limited set of rights. A license allows a licensee to make, use, sell, or exercise the patented invention for a specific period, within a particular territory, and under agreed-upon conditions. The ownership of the patent remains with the original patentee (the licensor). The licensee typically pays a fee or royalties in exchange for these rights. Licenses can be exclusive, granting rights to only one licensee, or non-exclusive, allowing the licensor to grant the same rights to multiple parties.

Step-by-Step Guide to the Transfer Process

The process of transferring a patent, whether through assignment or licensing, is governed by Sections 68 and 69 of the Patents Act, 1970. It requires a written agreement and subsequent registration with the Indian Patent Office (IPO) to be legally valid.

Step 1: Preliminary Considerations and Negotiation

Before drafting any legal document, the patent holder must take several key actions:

• Determine Ownership: The first and most critical step is to confirm that you are the sole and legitimate owner of the patent or have the authority to transfer it. If the invention was made during employment, the company may hold the rights. If there are co-owners, all parties must consent to the transfer.

• Patent Valuation: Assess the commercial value of the patent. This involves considering the market potential of the invention, the existing competition, and the remaining term of the patent. This valuation will form the basis for negotiation of the sale price or royalty rates.

• Identify the Right Partner: Whether it's a potential buyer (for assignment) or a company to manufacture and market the product (for licensing), identify a party that aligns with your commercial goals.

• Negotiate the Terms: Thoroughly negotiate all terms of the agreement. For an assignment, this includes the sale price and any warranties. For a license, this includes the duration, territory, scope of use, royalty payment structure, and a sub-licensing clause, if applicable.

Step 2: Drafting the Legal Agreement

The transfer must be documented in a formal, written agreement. This is a crucial step as per Section 68 of the Patents Act, which states that any transfer is not valid unless it is in writing and duly executed.

• For an Assignment Deed: The agreement should clearly state the transfer of all rights, title, and interest in the patent from the assignor to the assignee. It must include:

  • Full details of the parties involved (assignor and assignee).

  • Complete bibliographic information of the patent (patent number, title, date of grant).

  • The total consideration (amount of money) for the transfer.

  • An undertaking that the assignor has not created any other interests in the patent.

  • A dispute resolution clause.

• For a License Agreement: The agreement should be more detailed and specify the terms of the license. It should include:

  • Identification of the parties (licensor and licensee).

  • Precise description of the patented invention.

  • The type of license (exclusive, non-exclusive, etc.).

  • The scope of rights granted to the licensee (e.g., manufacturing, selling, importing).

  • The duration and territorial limitations of the license.

  • The financial terms, including royalty rates, payment schedule, and any upfront fees.

  • Provisions for sub-licensing, if permitted.

  • Termination clauses.

Step 3: Registration with the Indian Patent Office (IPO)

This is a mandatory step for the transfer to be legally effective and enforceable against third parties. As per Section 69 of the Patents Act, all assignments and licenses must be registered with the Controller of Patents.

• File the Prescribed Form: The application for registration of the transfer is to be filed using Form 16. This form must be filed jointly by the patentee and the person to whom the interest is being transferred, or by either party if the other consents.

• Required Documents: The application must be accompanied by a copy of the original deed or agreement that documents the transfer. It is recommended that this document be notarized or attested by witnesses for added credibility.

• Timeline: The application for registration should be filed within six months from the date of execution of the assignment or license deed. An extension of up to six months may be sought by paying the prescribed fee.

• Controller's Role: The Controller of Patents will review the application and the submitted documents. Once satisfied, the Controller will enter the details of the transfer in the Register of Patents. The registration is a public record and serves as official notice of the change in ownership or interest.

Step 4: Post-Registration Formalities

Once the transfer is officially recorded, the new owner or licensee assumes the corresponding rights and obligations.

• Enforcement of Rights: The assignee, now the proprietor, can sue for infringement of the patent. A registered exclusive licensee can also initiate infringement proceedings in their own name, subject to certain conditions.

• Maintenance: The new patentee is responsible for paying all future renewal fees to maintain the patent in force for its full term.

Key Legal Provisions to Remember

• Section 68 of the Patents Act, 1970: Mandates that any transfer of a patent or an interest therein, including assignments and licenses, must be in writing.

• Section 69 of the Patents Act, 1970: Requires the registration of all such transfers with the Controller of Patents to be valid. The non-registration of a transfer could render it unenforceable in a court of law.

• Form 16: The official form for the application to register a title or interest in a patent.

Conclusion

The sale or transfer of a patent in India is a significant legal and financial transaction. While it can be a lucrative way to commercialize an invention, it requires meticulous attention to detail and strict adherence to legal procedures. By following a structured approach—from negotiation and careful drafting of the legal agreement to the mandatory registration with the Indian Patent Office—a patent holder can ensure a smooth, legally compliant, and secure transfer of their valuable intellectual property. Given the complexities involved, it is highly recommended to seek the counsel of an experienced patent attorney or legal professional at every step of the process.
