Various modes of transfer of Patent Rights.

 In India, the transfer of patent rights is a legal process that allows a patentee to commercialize their invention by either selling it or allowing others to use it. Under the Patents Act, 1970 (Sections 68, 69, and 70), there are three primary modes of transfer:

1. Assignment

Assignment is the permanent transfer of ownership. The original patentee (the assignor) sells their entire interest or a portion of it to another party (the assignee).

• Legal Assignment: The transfer of an existing patent through a formal deed. The assignee becomes the new owner and can sue for infringement in their own name.

• Equitable Assignment: An agreement to assign in the future or an agreement to share a portion of the patent rights. Unlike a legal assignment, the assignee’s name is recorded in the register as an interested party, not the proprietor.

• Mortgage: A transfer where rights are given to a creditor as security for a loan. Once the loan is repaid, the rights revert to the original patentee.

2. Licensing

Licensing is a temporary transfer where the patentee (licensor) retains ownership but gives another party (licensee) permission to make, use, or sell the invention under specific conditions.

• Voluntary License: A mutual agreement between the owner and a third party, usually in exchange for royalties.

• Statutory / Compulsory License: Granted by the Controller of Patents without the owner's consent under specific circumstances (e.g., if the invention is not available to the public at an affordable price or if it's a national emergency).

• Exclusive vs. Non-Exclusive: An exclusive license prevents even the owner from using the patent, while a non-exclusive license allows the owner to grant rights to multiple parties simultaneously.

3. Transmission by Operation of Law

This mode occurs automatically without a formal contract. Rights are transferred due to specific legal events:

• Death: If the patentee dies, the rights are transmitted to their legal heirs or executors.

• Insolvency: If the patentee is declared bankrupt, the rights may pass to an official receiver to settle debts.

• Dissolution: If a company holding a patent is dissolved, the rights are transferred as part of the liquidation process.

Legal Requirements for a Valid Transfer

For an assignment or license to be legally binding in India, it must fulfill these criteria:

1. Written Form: Oral agreements are invalid. All terms and conditions must be documented.

2. Duly Executed: The document must be signed by both parties.

3. Registration: Under Section 69, the transfer must be registered with the Controller of Patents (typically via Form 16) within 6 months of execution to be recognized as proof of title.
