MPEP 106-Control of Inspection by Assignee (1)

When the USPTO receives conflicting instructions from multiple assignees or co-inventors regarding a patent application, it follows a specific protocol to ensure fair treatment of all parties. According to MPEP 106, the USPTO will not arbitrate disputes between the parties.

In such cases, the USPTO typically:

  • Suspends action on the application until the conflict is resolved
  • Notifies all parties of the conflicting instructions
  • Advises the parties to resolve the dispute among themselves or through the courts
  • Resumes prosecution only when clear, consistent instructions are received from all interested parties or when a court order is issued

This approach ensures that the USPTO remains neutral and that the rights of all assignees and inventors are protected throughout the patent prosecution process.

MPEP 300 - Ownership and Assignment (6)

When there are multiple assignees or a combination of partial assignees and inventors, establishing ownership for patent applications becomes more complex. According to MPEP 325 and 37 CFR 3.73(c)(2), each owner must submit a statement that either:

  1. Specifies the percentage of their ownership interest, accounting for the entire right, title, and interest in the application or patent, or
  2. Identifies all parties, including inventors, who together own the entire right, title, and interest, and states that all identified parties own the entire right, title, and interest.

The MPEP states: “Where there is more than one assignee (i.e., partial assignees) or a combination of partial assignees and inventors who have not assigned away their right, title and interest in the application, each owner must submit a statement under 37 CFR 3.73(c) that either:

(A) Specifies (by percentage) the extent of its ownership interest, so as to account for the entire right, title and interest in the application or patent by all parties. 37 CFR 3.73(c)(2)(i); or

(B) Identifies the parties including inventors who together own the entire right, title and interest and state that all the identified parties own the entire right, title and interest. 37 CFR 3.73(c)(2)(ii).”

If the extent of ownership is not clearly set forth, the USPTO may refuse to accept the submission as an establishment of ownership interest.

When there are multiple assignees for a patent application, patent, or reexamination proceeding, each partial assignee must provide a submission under pre-AIA 37 CFR 3.73(b) to take action before the USPTO. The process is as follows:

  1. Each partial assignee must submit their own pre-AIA 37 CFR 3.73(b) statement.
  2. In each submission, the extent of the assignee’s ownership interest must be clearly stated.
  3. The USPTO needs to determine if it has obtained action by all of the right, title, and interest holders (owners).
  4. If the extent of ownership is not clearly set forth, the USPTO may refuse to accept the submission.

This is outlined in MPEP 324, section VIII, which states:

“When an assignee seeks to take action in a matter before the Office with respect to a patent application, patent, or reexamination proceeding and the right, title, and interest therein is held by more than one assignee, each partial assignee must provide a submission under pre-AIA 37 CFR 3.73(b). In each submission, the extent of each assignee’s interest must be set forth so that the Office can determine whether it has obtained action by the entirety of the right, title and interest holders (owners).”

The MPEP further notes: “If the extent of the partial assignee’s ownership interest is not set forth in the submission under pre-AIA 37 CFR 3.73(b), the Office may refuse to accept the submission as an establishment of ownership interest.”

When multiple assignees seek to take action in a patent matter, each partial assignee must provide a submission under 37 CFR 3.73(c). According to the MPEP:

In each submission, the extent of each assignee’s interest must be set forth so that the Office can determine whether it has obtained action by the entirety of the right, title and interest holders (owners). 37 CFR 3.73(c)(2)(i).

Assignees have two options:

  1. Specify the percentage of ownership interest for each assignee, accounting for 100% of ownership.
  2. Identify all parties (including inventors) who together own the entire right, title, and interest, and state that all identified parties own the entire right, title, and interest.

The MPEP warns: “If the extent of the partial assignee’s ownership interest is not set forth in the submission under 37 CFR 3.73(c), the Office may refuse to accept the submission as an establishment of ownership interest.”

The USPTO has specific provisions for handling partial assignees in patent issuance:

  1. If one or more assignees, together with one or more inventors, hold the entire right, title, and interest in the application, the patent may issue in the names of both the assignee(s) and the inventor(s).
  2. If multiple assignees hold the entire right, title, and interest to the exclusion of all inventors, the patent may issue in the names of the multiple assignees.

This is outlined in 37 CFR 3.81(c): (1) If one or more assignee, together with one or more inventor, holds the entire right, title, and interest in the application, the patent may issue in the names of the assignee and the inventor. (2) If multiple assignees hold the entire right, title, and interest to the exclusion of all the inventors, the patent may issue in the names of the multiple assignees.

Can multiple assignees take action in a patent application?

Yes, multiple assignees can take action in a patent application, but there are specific requirements they must meet. The MPEP 325 states:

“Where multiple assignees are named in the statement under 37 CFR 3.73(c) and/or the Form PTO/AIA/96, and they are not named as joint owners in a single statement or form, the statement or form must be modified accordingly.”

This means that:

  • Multiple assignees can be named in a single statement or form if they are joint owners
  • If they are not joint owners, separate statements or forms must be submitted for each assignee
  • Each assignee must establish their right to take action as per 37 CFR 3.71 and 37 CFR 3.73

It’s important to note that the USPTO will not mediate disputes between assignees. If there are conflicting instructions from multiple assignees, the USPTO may suspend action on the application.

Yes, a patent can be issued to multiple assignees or a combination of assignees and inventors. According to MPEP 307, there are two scenarios:

  1. Partial assignees and inventors: “If one or more assignee, together with one or more inventor, holds the entire right, title, and interest in the application, the patent may issue in the names of the assignee and the inventor.”
  2. Multiple assignees: “If multiple assignees hold the entire right, title, and interest to the exclusion of all the inventors, the patent may issue in the names of the multiple assignees.”

These provisions allow for flexibility in patent issuance when ownership is shared among multiple parties.

MPEP 307 - Issue to Non - Applicant Assignee (2)

The USPTO has specific provisions for handling partial assignees in patent issuance:

  1. If one or more assignees, together with one or more inventors, hold the entire right, title, and interest in the application, the patent may issue in the names of both the assignee(s) and the inventor(s).
  2. If multiple assignees hold the entire right, title, and interest to the exclusion of all inventors, the patent may issue in the names of the multiple assignees.

This is outlined in 37 CFR 3.81(c): (1) If one or more assignee, together with one or more inventor, holds the entire right, title, and interest in the application, the patent may issue in the names of the assignee and the inventor. (2) If multiple assignees hold the entire right, title, and interest to the exclusion of all the inventors, the patent may issue in the names of the multiple assignees.

Yes, a patent can be issued to multiple assignees or a combination of assignees and inventors. According to MPEP 307, there are two scenarios:

  1. Partial assignees and inventors: “If one or more assignee, together with one or more inventor, holds the entire right, title, and interest in the application, the patent may issue in the names of the assignee and the inventor.”
  2. Multiple assignees: “If multiple assignees hold the entire right, title, and interest to the exclusion of all the inventors, the patent may issue in the names of the multiple assignees.”
