MPEP 2300 – Interference And Derivation Proceedings (9)
An interference in patent law is a proceeding to determine which party has the right to a patent when two or more parties claim the same invention. The Manual of Patent Examining Procedure (MPEP) Chapter 2300 covers interference and derivation proceedings.
According to MPEP 2304, “The suggestion for an interference may come from an applicant or from an examiner.” This process is crucial in determining priority of invention when multiple parties claim the same or similar inventions.

Filing a divisional application during an interference can serve as a strategic move to manage claims that may be affected by the interference while allowing other claims to proceed. The MPEP 2307.03 suggests this approach as a way to minimize the impact of suspension on patent term adjustment:
“The applicant may then file a divisional application with the interfering claims, which may be suspended.”
The purpose of filing a divisional application in this context includes:
- Separating interfering claims from non-interfering claims
- Allowing non-interfering claims to proceed to issuance
- Preserving patent term for non-interfering claims
- Maintaining the option to pursue interfering claims later
This strategy aligns with the MPEP’s guidance on using restriction requirements:
“For instance, the examiner could require restriction in accordance with 35 U.S.C. 121, of the application to only the claims that do not interfere so that they can be issued.”
By filing a divisional application, applicants can effectively manage their patent portfolio while navigating the complexities of an interference proceeding.

No, once a patent application becomes involved in a derivation proceeding, the examiner cannot continue regular examination. According to MPEP 2313:
“The examiner may not act on an involved patent or application except as the Board may authorize.”
This means that all examination activities are suspended unless the Patent Trial and Appeal Board (PTAB) specifically authorizes an action. The PTAB has exclusive jurisdiction over the application during the proceeding.

How does access to files under 37 CFR 41.109 differ from public access under 37 CFR 1.11 and 1.14?
Access to files under 37 CFR 41.109 is distinct from public access under 37 CFR 1.11 and 1.14. The key differences are:
- 37 CFR 41.109 specifically applies to opposing parties in contested cases.
- It allows access to involved patents, applications, and accorded benefit applications.
- This access is independent of public availability under 37 CFR 1.11 and 1.14.
As stated in MPEP 2307.02: “The availability of a file to an opposing party under 37 CFR 41.109 has no bearing on whether a file is otherwise available under 37 CFR 1.11 or 1.14.” This means that even if a file is not publicly available, it may still be accessible to an opposing party in a contested case under 37 CFR 41.109.
To learn more:
Yes, there are limitations on the types of files an opposing party can access in a contested case. According to MPEP 2307.02, access is ordinarily limited to specific categories of records:
- The application file for an involved patent
- An involved application
- An application for which a party has been accorded benefit under subpart E of 37 CFR 41
The MPEP explicitly states: “Access and copies will ordinarily only be authorized for the following records: (1) The application file for an involved patent; (2) An involved application; and (3) An application for which a party has been accorded benefit under subpart E of this part.”
It’s important to note that this access is distinct from public access and is specifically granted for the purposes of the contested case. Access to other types of records may be more restricted and would likely require additional justification or special authorization from the Board.

According to MPEP 2308.01, there are multiple types of judgments in an interference that can lead to the final disposal of claims. The section states: “Judgment against a claim in an interference, including any judgment on priority or patentability, finally disposes of the claim.” This means that the following types of judgments can result in final disposal:
- Priority judgments: Determining which party was the first to invent
- Patentability judgments: Deciding if the claim meets the requirements for patentability
- Other adverse judgments: Any other judgment that goes against the claim in question
Each of these judgments, when rendered against a claim, results in the final disposal of that claim, preventing further prosecution in its current form.
To learn more:
After a final decision in an interference proceeding, the claims are handled as follows:
- Claims that were not involved in the interference remain pending in the application.
- Claims that were involved in the interference are disposed of according to the judgment.
- Claims that correspond to the count(s) of the interference are disposed of in accordance with the judgment.
As stated in MPEP 2308.01: “The claims of an application or patent which correspond to the count or counts of an interference will be disposed of in accordance with the judgment in the interference.”
To learn more:
According to MPEP 2304.01(d), finally refused or canceled claims are generally excluded from an interference proceeding. The MPEP states:
“Claims which have been finally refused or canceled are generally excluded from the interference.”
This treatment of finally refused or canceled claims serves several purposes:
- It streamlines the interference process by focusing on active, potentially patentable claims.
- It prevents the reintroduction of claims that have already been determined to be unpatentable.
- It helps maintain the efficiency and clarity of the interference proceeding.
However, it’s important to note that the word “generally” in the MPEP indicates that there might be rare exceptions to this rule, which would be determined by the administrative patent judge (APJ) based on the specific circumstances of the case.
To learn more:
According to MPEP 2307.02, any request for access to or copies of Office records directly related to a contested case must adhere to the following requirements:
- The request must be filed with the Board.
- It must precisely identify the records being requested.
- For copies, the appropriate fee set under 37 CFR 1.19(b) must be included.
As stated in the MPEP: “Any request from a party for access to or copies of Office records directly related to a contested case must be filed with the Board. The request must precisely identify the records and in the case of copies include the appropriate fee set under § 1.19(b) of this title.”
