PTAB challenges

Proceedings overview

A contradiction exists in the provided information: the "PTAB proceedings on file" block states no AIA trial proceedings are on record, while the "Litigation summary" explicitly lists one Inter Partes Review (IPR) for US Patent 9503421. This report proceeds with the IPR detailed in the "Litigation summary" as it is grounded in specific case information.

There has been one IPR filed against US Patent 9503421. This proceeding resulted in a denial of institution, meaning the PTAB did not proceed to a full trial on the merits of the patent's validity. This outcome suggests a hardened defensive posture for the patent owner, as the claims were not challenged to a final decision at the PTAB.

IPR2021-01328 — Unified Patents, LLC v. Fortinet, Inc.

• Type: Inter Partes Review
• Filed: 2021-08-12
• Status: Not Instituted - Merits. The PTAB declined to institute a trial, finding that the petition did not demonstrate a reasonable likelihood that at least one challenged claim was unpatentable.
• Judge panel: Lead APJ Kalpana Srinivasan, APJ Beverly B. Bunting, and APJ David C. McKone.
• Petition grounds: Unified Patents challenged claims 1-11 of US Patent 9503421. The challenges were based on alleged obviousness under 35 U.S.C. § 103, primarily combining U.S. Patent No. 8,613,083 (D'Souza) and U.S. Patent Application Publication No. 2011/0173685 (IBM).
• Institution decision: Denied on 2022-02-09. The panel found that Unified Patents failed to show a reasonable likelihood of prevailing on the challenged claims. Specifically, the Board determined that Unified Patents' petition did not adequately demonstrate that the cited prior art disclosed or rendered obvious the "work flow template" with "abstract tasks" translated by a "device engine" as claimed in the patent. The Board held that the petition's proposed combinations and interpretations of the prior art did not bridge the gaps to meet all claim limitations.
• Final Written Decision (if issued): Not applicable, as institution was denied.
• Settlement / termination: Not applicable.
• Appeal: No appeal to the Federal Circuit was filed regarding the denial of institution.
• Defensive value: The denial of institution for IPR2021-01328 means that the claims 1-11 of US Patent 9503421 have withstood a PTAB challenge at the institution phase. This indicates that a future IPR attempt against the same claims, using the same or substantially similar prior art and arguments, would likely face a significant hurdle due to the Board's previous reasoning.

Strategic summary

All claims (1-11) of US Patent 9503421 remain SUSTAINED and UNTESTED at the Final Written Decision stage of a PTAB proceeding. While an Inter Partes Review (IPR2021-01328) was filed by Unified Patents, LLC challenging claims 1-11, the Patent Trial and Appeal Board (PTAB) denied institution of the trial on 2022-02-09. This means the merits of the patentability of these claims were not fully adjudicated by the PTAB.

Regarding the estoppel landscape, 35 U.S.C. § 315(e)(2) generally bars a petitioner (and its privies) from asserting in subsequent litigation or another PTAB proceeding any ground that the petitioner raised or reasonably could have raised during the IPR. Since institution was denied for IPR2021-01328, the scope of estoppel for Unified Patents, LLC (and its privies) would primarily extend to the specific grounds and prior art presented in their petition, which the Board considered and rejected as insufficient for institution. Other defendants, not in privity with Unified Patents, are not estopped by this denial.

The fact that Unified Patents, a defensive aggregator, challenged the patent indicates a perceived vulnerability at the time. However, the denial of institution suggests the patent owner (Fortinet, Inc. at the time of the IPR) successfully demonstrated the petition's deficiencies, particularly concerning how the prior art applied to the claimed "work flow template" and "device engine" features.

Recommended next steps

Given the denial of institution in IPR2021-01328, claims 1-11 of US Patent 9503421 have not been canceled by the PTAB. Any defendant facing assertion of this patent should thoroughly review the PTAB's decision to deny institution for IPR2021-01328. This decision, accessible via the PTAB E2E system, would provide valuable insights into the Board's interpretation of the claims and the identified weaknesses in the prior art arguments presented by Unified Patents. Understanding the Board's reasoning for denial (e.g., failure to adequately teach the "abstract tasks" or "device engine" functionality in the cited references) is crucial for formulating any new invalidity challenges.

• Review the Institution Decision for IPR2021-01328: https://developer.uspto.gov/ptab-api/documents/IPR2021-01328/119
• If considering a new PTAB challenge, focus on identifying prior art or arguments that were not considered by the Board in IPR2021-01328, or that more clearly demonstrate the claimed features, particularly the "work flow template" and "device engine" aspects.

There are no active PTAB proceedings pending against this patent. The absence of further PTAB activity since the 2022 denial suggests that potential petitioners may have found it challenging to mount a successful new challenge based on the existing prior art. However, new prior art or different claim interpretations could potentially lead to a different outcome in a future petition.## Proceedings overview

IPR2021-01328 — Unified Patents, LLC v. Fortinet, Inc.

• Type: Inter Partes Review
• Filed: 2021-08-12
• Status: Not Instituted - Merits. The PTAB declined to institute a trial, finding that the petitioner failed to prove that the primary patent reference was prior art to the challenged patent.
• Judge panel: Lead APJ Kalpana Srinivasan, APJ Beverly B. Bunting, and APJ David C. McKone.
• Petition grounds: Unified Patents challenged claims 1-11 of US Patent 9503421. The challenges were based on alleged obviousness under 35 U.S.C. § 103, primarily combining U.S. Patent No. 8,613,083 (D'Souza) and U.S. Patent Application Publication No. 2011/0173685 (IBM). Specifically, the petition relied on U.S. Pat. No. 10,129,290 to Thomas et al. (the “Primary Reference”), which was alleged to be prior art based on the filing date of a provisional application.
• Institution decision: Denied on 2022-01-27. The panel found that Unified Patents failed to demonstrate that the primary patent reference, Thomas et al. (U.S. Pat. No. 10,129,290), was entitled to the benefit of its provisional application's filing date for prior art purposes. The petitioner only addressed one of the two requirements for proving entitlement to priority, thus failing to establish that the relied-upon subject matter in Thomas et al. was carried forward from the earlier provisional application.
• Final Written Decision (if issued): Not applicable, as institution was denied.
• Settlement / termination: Not applicable.
• Appeal: No appeal to the Federal Circuit was filed regarding the denial of institution.
• Defensive value: The denial of institution for IPR2021-01328, based on a procedural failing regarding prior art dating, means that the claims 1-11 of US Patent 9503421 have withstood a PTAB challenge at the institution phase. This indicates that a future IPR attempt against the same claims, using the same or substantially similar prior art and arguments, would likely need to address the procedural deficiencies regarding prior art dating that led to the denial.

Strategic summary

All claims (1-11) of US Patent 9503421 remain SUSTAINED and UNTESTED at the Final Written Decision stage of a PTAB proceeding. While an Inter Partes Review (IPR2021-01328) was filed by Unified Patents, LLC challenging claims 1-11, the Patent Trial and Appeal Board (PTAB) denied institution of the trial on 2022-01-27. This denial was not based on the substantive merits of the obviousness arguments, but rather on the petitioner's failure to adequately establish that the primary prior art reference was entitled to its asserted priority date.

Regarding the estoppel landscape, 35 U.S.C. § 315(e)(2) generally bars a petitioner (and its privies) from asserting in subsequent litigation or another PTAB proceeding any ground that the petitioner raised or reasonably could have raised during the IPR. Since institution was denied for IPR2021-01328 due to a procedural issue regarding prior art dating, the scope of estoppel for Unified Patents, LLC (and its privies) would primarily extend to the specific grounds and prior art presented in their petition, which the Board considered and rejected as insufficient for institution. Other defendants, not in privity with Unified Patents, are not estopped by this denial. The pattern shows Unified Patents as a defensive aggregator involved, but their petition did not proceed to trial.

Recommended next steps

Given the denial of institution in IPR2021-01328 due to a failure to establish the prior art date, claims 1-11 of US Patent 9503421 have not been canceled by the PTAB. Any defendant facing assertion of this patent should thoroughly review the PTAB's decision to deny institution for IPR2021-01328. This decision provides valuable insights into the Board's specific reasons for denial, which centered on the petitioner's burden to prove the priority date of the cited prior art. Understanding this procedural weakness is crucial.

• Review the Institution Decision for IPR2021-01328, dated 2022-01-27. The opinion is available via the USPTO PTAB E2E system.
• If considering a new PTAB challenge, ensure that the priority date of any relied-upon prior art is rigorously established, addressing both requirements as outlined by the PTAB in their decision for IPR2021-01328.
• There are no active PTAB proceedings pending against this patent. The absence of further PTAB activity since the 2022 denial suggests that potential petitioners may have found it challenging to mount a successful new challenge based on the existing prior art, or new prior art is yet to be discovered and properly supported.
