Patent Law FAQ

Joint ownership in patents and patent applications occurs when two or more parties share ownership rights. According to MPEP 301:

“Joint inventors are treated as joint owners of the invention unless there is an assignment.”

Key aspects of joint ownership include:

• Each joint owner has the right to make, use, sell, and license the invention without consent from other owners.
• Profits do not need to be shared unless there’s a specific agreement.
• All joint owners must agree to sell or assign the entire patent to a third party.
• In infringement suits, all joint owners must be joined as plaintiffs.

It’s important for joint owners to have clear agreements in place to avoid potential conflicts and ensure proper management of the patent rights.

Patent assignment records can be accessed online through the USPTO’s Assignment Search database. The MPEP states: Assignment records that affect the title of patents and patent applications are recorded in the USPTO’s Assignment Recordation Branch. To access these records:

• Visit the USPTO Assignment Search website
• Enter the relevant patent or application number, assignee name, or other search criteria
• Review the search results for assignment information

This online database provides public access to assignment records, allowing for easy verification of patent ownership.

To record an assignment of a patent or patent application, the following requirements must be met:

• The assignment must be in writing.
• It must be signed by the assignor (the person or entity transferring ownership).
• The document must identify the patent or application by number.
• The assignment must be submitted to the USPTO along with the required fee.

According to MPEP 301: “An assignment relating to a patent must be submitted to the USPTO for recordation as an absolute requirement for enforcing the patent or application against third parties.” This recordation provides constructive notice to the public of the assignment.

What information is available in the USPTO’s assignment database?

The USPTO’s assignment database contains a wealth of information related to patent ownership. According to MPEP 301.01:

‘The USPTO maintains a database containing the assignment records of patents and patent applications. The USPTO also maintains a cumulative index of number of assignments recorded on the day in which they are recorded.’

The database typically includes:

• Patent or application numbers
• Names of assignors and assignees
• Dates of assignment execution and recording
• Brief descriptions of the interests conveyed
• Reel and frame numbers for locating documents

This information is crucial for determining the current ownership status of patents and applications, which is essential for various legal and business purposes.

How are historical patent assignment records maintained?

The USPTO maintains historical patent assignment records separately from more recent records. MPEP 301.01 explains:

‘The historical database of assignments is maintained separate and apart from the database of assignments affecting title recorded since 1980.’

This means that:

• Records prior to August 1980 are kept in a separate historical database
• These older records may not be available through the online Patent Assignment Search
• Accessing historical records may require different procedures or direct contact with the USPTO

For researchers or legal professionals needing access to pre-1980 assignment records, it’s advisable to contact the USPTO’s Patent and Trademark Resource Centers or the Assignment Recordation Branch for assistance.

Joint owners of a patent have specific rights as outlined in 35 U.S.C. 262, which states:

‘In the absence of any agreement to the contrary, each of the joint owners of a patent may make, use, offer to sell, or sell the patented invention within the United States, or import the patented invention into the United States, without the consent of and without accounting to the other owners.’

This means that each joint owner can independently exercise the full rights of the patent without needing permission from or owing compensation to the other joint owners, unless they have a separate agreement stating otherwise.

Recording a patent assignment with the USPTO is crucial for several reasons:

1. Legal Notice: It provides public notice of the assignment, which is important for establishing priority against subsequent purchasers or mortgagees.
2. Prima Facie Evidence: As stated in MPEP 301.01, ‘The recording of an assignment with the USPTO is prima facie evidence of its execution.’
3. Chain of Title: It helps maintain a clear chain of title for the patent or application.
4. Enforcement Rights: Proper recording can affect the ability to enforce patent rights or collect damages in infringement cases.

The MPEP emphasizes the importance of recording by stating, ‘An assignment must be recorded in the USPTO within three months from its date or prior to the date of a subsequent purchase or mortgage to be valid against a subsequent purchaser or mortgagee.’ This underscores the time-sensitive nature of recording assignments to protect legal rights.

The USPTO provides an online database for searching patent assignment records. According to MPEP 301.01, ‘Assignment records, digests, and indexes are available in the public search room of the USPTO.’ To search online:

• Visit the USPTO Patent Assignment Search page
• Enter relevant information such as patent number, assignee name, or assignor name
• Review the search results for the desired assignment information

The MPEP states, ‘The assignment records of patents and applications are open to public inspection and copies of these records may be obtained upon request and payment of the fee set forth in 37 CFR 1.19(b)(3).’
