Patent Can Be Involved in Interference Proceeding During Ex Parte Reexamination
Note:
A patent being reexamined may be involved in an interference proceeding if it and another application claim the same invention, and at least one of the application’s claims are patentable.

A patent being reexamined in an ex parte reexamination proceeding may be involved in an interference proceeding with at least one application, where the patent and the application are claiming the same patentable invention, and at least one of the application’s claims to that invention are patentable to the applicant. See MPEP Chapter 2300.

Interference Decisions Must Align with Reexamination Status
Note:
Decisions in interference proceedings must consider and align with the status of concurrent reexamination proceedings.

The general policy of the Office is that a reexamination proceeding will not be delayed, or stayed, because of an interference or the possibility of an interference. The reason for this policy is the requirement of 35 U.S.C. 305 that all reexamination proceedings be conducted with “special dispatch” within the Office. In general, the Office will follow the practice of making the required and necessary decisions in the reexamination proceeding and, at the same time, going forward with the interference to the extent desirable. It is noted that 37 CFR 41.103 provides the Board with the flexibility to tailor a specific solution to occurrences where reexamination and interference proceedings for the same patent are copending, as such occurrences may arise. Decisions in the interference will take into consideration the status of the reexamination proceeding and what is occurring therein. The decision as to what actions are taken in the interference will, in general, be taken in accordance with normal interference practice.

Reexamination Proceeding Cannot Be Involved in Interference
Note:
A reexamination proceeding cannot be involved in an interference proceeding even if a patent being reexamined might become involved.

Although a patent being reexamined via a reexamination proceeding may become involved in an interference proceeding, the reexamination proceeding itself can never be involved in an interference proceeding. See 35 U.S.C. 135 subsection (a) which states that “[w]henever an application is made for a patent which, in the opinion of the Director, would interfere with any pending application, or with any unexpired patent, an interference may be declared” (emphasis added). The reexamination proceeding is neither an application nor a patent.

Continued Prosecution of Application During Interference
Note:
The application must continue prosecution even if claims interfere with a patent under reexamination, subject to OPLA authorization.

When an amendment is filed in a pending application seeking to provoke an interference with a patent involved in a reexamination proceeding, the applicant must comply with 37 CFR 41.202(a), including identifying the patent under reexamination with which interference is sought. The corresponding application claims may be rejected on any applicable ground including, if appropriate, the prior art cited in the reexamination proceeding. See MPEP Chapter 2300. Prosecution of the application should continue as far as possible. If the application is placed in condition for allowance and still contains claims which interfere with claims of the patent under reexamination, then an interference should ordinarily be proposed between the application and the patent. The examiner must notify the Office of Patent Legal Administration (OPLA) before proposing the interference, and such an interference may not be proposed unless authorized by OPLA.

Examiner Must Propose Interference If Claims Interfere
Note:
If patent claims in reexamination interfere with application claims, the examiner must propose an interference.

Once the reexamination certificate has issued and published, the examiner should review the certificate to see if it makes any changes in the patent claims and then evaluate whether the patent still contains claims which interfere with claims of the application. If the claims do interfere, then the examiner should propose an interference. See MPEP Chapter 2300.

Motion for Suspension Must Be Presented to Administrative Patent Judge
Note:
A motion to suspend an interference pending reexamination must be presented to the administrative patent judge, who will decide based on specific facts. Suspension is not favored and typically considered only after a reexamination order is issued.

A miscellaneous motion under 37 CFR 41.121(a)(3) to suspend an interference pending the outcome of a reexamination proceeding may be made at any time during the interference by any party thereto. See 37 CFR 41.123(b) for the procedure. The motion must be presented to the administrative patent judge who will decide the motion based on the particular fact situation. However, suspension is not favored. Normally, no consideration will be given such a motion unless and until a reexamination order is issued, nor will suspension of the interference normally be permitted until after any motions have been disposed of in the interference proceeding. If the motion under 37 CFR 41.121(a)(3) is denied by the administrative patent judge, a request to stay the interference may be made to the Director of the USPTO under 37 CFR 1.565(e).

Patent Owner Must Notify Office of Interference Involvement During Reexamination
Note:
The patent owner must file a notice in the reexamination proceeding when their patent becomes involved in an interference to keep the Office informed and avoid procedural surprise.

Under 37 CFR 1.565, the patent owner in a reexamination proceeding before the Office is required to notify the Office when the patent being reexamined becomes involved in an interference. To do so, the patent owner must file in the reexamination proceeding a paper giving notice of the interference proceeding. The requirements of 37 CFR 1.565, and of 37 CFR 41.8(a) (see the preceding paragraph), are designed to keep the Office and the appropriate parties informed of activity which is relevant to reexamination and interference proceedings and, to the extent possible, to eliminate procedural surprise.

Premature Petitions to Stay Reexamination Will Be Returned
Note:
Petitions filed before the order to reexamine will not be considered and will be returned without a copy being retained by the Office.

Any petition to stay a reexamination proceeding, because of an interference, which is filed prior to the determination (37 CFR 1.515) and order to reexamine (37 CFR 1.525) will not be considered, but will be returned to the party submitting the same. The decision returning such a premature petition will be made of record in the reexamination file, but no copy of the petition will be retained by the Office. A petition to stay the reexamination proceeding because of the interference may be filed by the patent owner as a part of the patent owner’s statement under 37 CFR 1.530 or subsequent thereto. If a party to the interference, other than the patent owner, is a requester of the reexamination, that party may petition to stay the reexamination proceeding as a part of a reply pursuant to 37 CFR 1.535. If the other party to the interference is not the requester, any petition by that party is improper under 37 CFR 1.550(g) and will not be considered. Any such improper petitions will be returned to the party submitting the same. Premature petitions to stay the reexamination proceedings, i.e., those filed prior to the determination (37 CFR 1.515) and order to reexamine (37 CFR 1.525), will be returned by the Central Reexamination Unit (CRU) or Technology Center (TC) Director as premature. Petitions to stay filed subsequent to the date of the order for reexamination will be referred to OPLA for decision. All decisions on the merits of petitions to stay a reexamination proceeding because of an interference will be made in OPLA.

Premature Petitions to Stay Reexamination Will Be Returned
Note:
A petition to stay a reexamination proceeding due to an interference filed before the determination and order to reexamine will not be considered but returned to the submitter.

Any petition to stay a reexamination proceeding, because of an interference, which is filed prior to the determination (37 CFR 1.515) and order to reexamine (37 CFR 1.525) will not be considered, but will be returned to the party submitting the same. The decision returning such a premature petition will be made of record in the reexamination file, but no copy of the petition will be retained by the Office. A petition to stay the reexamination proceeding because of the interference may be filed by the patent owner as a part of the patent owner’s statement under 37 CFR 1.530 or subsequent thereto. If a party to the interference, other than the patent owner, is a requester of the reexamination, that party may petition to stay the reexamination proceeding as a part of a reply pursuant to 37 CFR 1.535. If the other party to the interference is not the requester, any petition by that party is improper under 37 CFR 1.550(g) and will not be considered. Any such improper petitions will be returned to the party submitting the same. Premature petitions to stay the reexamination proceedings, i.e., those filed prior to the determination (37 CFR 1.515) and order to reexamine (37 CFR 1.525), will be returned by the Central Reexamination Unit (CRU) or Technology Center (TC) Director as premature. Petitions to stay filed subsequent to the date of the order for reexamination will be referred to OPLA for decision. All decisions on the merits of petitions to stay a reexamination proceeding because of an interference will be made in OPLA.

Reexamination and Interference Proceedings for Same Patent Copending
Note:
The Office will make necessary decisions in reexamination while proceeding with interference, as allowed by 37 CFR 41.103.

The general policy of the Office is that a reexamination proceeding will not be delayed, or stayed, because of an interference or the possibility of an interference. The reason for this policy is the requirement of 35 U.S.C. 305 that all reexamination proceedings be conducted with “special dispatch” within the Office. In general, the Office will follow the practice of making the required and necessary decisions in the reexamination proceeding and, at the same time, going forward with the interference to the extent desirable. It is noted that 37 CFR 41.103 provides the Board with the flexibility to tailor a specific solution to occurrences where reexamination and interference proceedings for the same patent are copending, as such occurrences may arise. Decisions in the interference will take into consideration the status of the reexamination proceeding and what is occurring therein. The decision as to what actions are taken in the interference will, in general, be taken in accordance with normal interference practice.

Interference Proposed for Interfering Claims After Allowance
Note:
An interference must be proposed if the application, after being placed in condition for allowance, still contains claims that interfere with those of a patent under reexamination.

When an amendment is filed in a pending application seeking to provoke an interference with a patent involved in a reexamination proceeding, the applicant must comply with 37 CFR 41.202(a), including identifying the patent under reexamination with which interference is sought. The corresponding application claims may be rejected on any applicable ground including, if appropriate, the prior art cited in the reexamination proceeding. See MPEP Chapter 2300. Prosecution of the application should continue as far as possible. If the application is placed in condition for allowance and still contains claims which interfere with claims of the patent under reexamination, then an interference should ordinarily be proposed between the application and the patent. The examiner must notify the Office of Patent Legal Administration (OPLA) before proposing the interference, and such an interference may not be proposed unless authorized by OPLA.
