What are Patent Assignments?
What is a patent assignment? In general, a Patent Assignment transfers ownership of the entire patent right, title, and interest owned by one party to a second party.
Patent Assignments are a type of contract between the Assignor (current holder) of Patent rights and the Assignee (new owner) of Patent rights. Recording an executed Assignment in the Patent Offices gives notice of the change in the Patent owner.
Recording ownership of a Patent is similar to recording a deed for real property — like your house. The recording of the deed to your house gives notice of your current ownership and specifies the location of that home in the State. Recording a Patent Assignment gives notice of ownership and the location of your intangible Patent rights.
National and Regional Patent Offices
The European Patent Office is a regional Patent Office and the Japanese and United States Patent Offices are national Patent Offices.
Each national or regional jurisdiction has specific formats and rules associated with recording the ownership of Patent rights. European, Japanese, and United States Patent Offices have required wording and procedures for recording an Assignment in the European, Japanese, or United States Patent Office.
- For an English language Assignment of Patent Rights, the Japanese Patent Office will accept a Japanese/English bilingual Assignment to record.
- The European Patent Office will accept an English, French, or German language Assignment. After the European Patent is granted, assignments of the Validations of the European Patent are required in most member states’ Patent Offices where the current owner asserts the European Patent’s rights.
- The USPTO accepts English language Assignments. (Non-English Assignments must be translated/transliterated into English.)
Assignments of Patent Applications can also be recorded in Patent Offices. Each jurisdiction will have different rules for recording ownership of Patent Applications. In the United States, when the US Patent Application issues as a US Patent, the ownership of the Patent Application applies to the US Patent until the ownership is assigned to another person/entity.
35 United States Code (U.S.C) 261 Ownership; assignment, reads:
“Subject to the provisions of this title, patents shall have the attributes of personal property. The Patent and Trademark Office shall maintain a register of interests in patents and applications for patents and shall record any document related thereto upon request, and may require a fee therefor.
Applications for patent, patents, or any interest therein, shall be assignable in law by an instrument in writing. The applicant, patentee, or his assigns or legal representatives may in like manner grant and convey an exclusive right under his application for patent, or patents, to the whole or any specified part of the United States.
A certificate of acknowledgment under the hand and official seal of a person authorized to administer oaths within the United States, or, in a foreign country, of a diplomatic or consular officer of the United States or an officer authorized to administer oaths whose authority is proved by a certificate of a diplomatic or consular officer of the United States, or apostille of an official designated by a foreign country which, by treaty or convention, accords like effect to apostilles of designated officials in the United States, shall be prima facie evidence of the execution of an assignment, grant, or conveyance of a patent or application for patent.
An interest that constitutes an assignment, grant, or conveyance shall be void as against any subsequent purchaser or mortgagee for valuable consideration, without notice, unless it is recorded in the Patent and Trademark Office within three months from its date or prior to the date of such subsequent purchase or mortgage.”
For Assignments of US Patents and US Patent Applications – because of 35 U.S.C. (U.S.C) 261, Business Patent Law, PLLC advises its clients:
- In the United States to execute Assignments of Patents or Patent Applications before a notary public.
- In a jurisdiction other than the United States, to execute the Assignments before the appropriate apostille.
