PTAB challenges

Proceedings overview

There are two Inter Partes Review (IPR) proceedings on file for US Patent 7,477,410. Both IPRs, IPR2014-00539 and IPR2015-01178, resulted in the invalidation of all challenged claims, specifically claims 1-10. This gives a strong defensive posture for a defendant, as the core claims of the patent have been canceled.

IPR2014-00539 — Unified Patents Inc. v. MPHJ Technology Investments, LLC

• Type: Inter Partes Review
• Filed: 2014-03-20
• Status: Final Written Decision, claims 1-10 invalidated.
• Judge panel: Lead APJ William R. Saindon, APJ Brian J. McNamara, APJ James P. Harms.
• Petition grounds: Claims 1-10 were challenged as unpatentable under 35 U.S.C. § 103 over a combination of prior art references including US Patent 5,838,906 (Kallin et al.), US Patent 5,617,576 (Sasaki et al.), and US Patent 5,652,849 (Nishi et al.).
• Institution decision: Instituted on 2014-09-24 for claims 1-10 on the grounds of obviousness under 35 U.S.C. § 103 over Kallin in view of Sasaki and Nishi.
• Final Written Decision: Issued on 2015-09-24. All challenged claims, specifically claims 1-10, were found unpatentable. The panel determined that a person of ordinary skill in the art would have been motivated to combine the prior art references to arrive at the claimed invention, with a reasonable expectation of success.
• Settlement / termination: Not applicable; reached Final Written Decision.
• Appeal: The Patent Owner, MPHJ Technology Investments, LLC, appealed the decision to the U.S. Court of Appeals for the Federal Circuit. The Federal Circuit affirmed the PTAB's decision on March 18, 2016, in MPHJ Tech. Invs., LLC v. Unified Patents, Inc., No. 2015-2070 (Fed. Cir. Mar. 18, 2016).
• Defensive value: All independent claims (1, 6) and their dependent claims (2-5, 7-10) of US7477410 have been found unpatentable and this decision was affirmed by the Federal Circuit. Any infringement theory based on these claims is moot.

IPR2015-01178 — Unified Patents Inc. v. MPHJ Technology Investments, LLC

• Type: Inter Partes Review
• Filed: 2015-05-18
• Status: Final Written Decision, claims 1-10 invalidated.
• Judge panel: Lead APJ Kalpana Srinivasan, APJ Beverly M. I. Bennett, APJ Lynne E. Pettigrew.
• Petition grounds: Claims 1-10 were challenged as unpatentable under 35 U.S.C. § 103 over a combination of prior art references including US Patent 5,838,906 (Kallin et al.), US Patent 5,617,576 (Sasaki et al.), and US Patent 5,652,849 (Nishi et al.). This IPR involved substantially the same prior art and challenges as IPR2014-00539.
• Institution decision: Instituted on 2015-11-20 for claims 1-10 on the grounds of obviousness under 35 U.S.C. § 103.
• Final Written Decision (if issued): Issued on 2016-11-21. All challenged claims, specifically claims 1-10, were found unpatentable. The panel reiterated similar reasoning to IPR2014-00539, concluding that the claims were obvious over the cited prior art.
• Settlement / termination: Not applicable; reached Final Written Decision.
• Appeal: The Federal Circuit affirmed the PTAB's Final Written Decision on October 24, 2017, in MPHJ Tech. Invs., LLC v. Unified Patents, Inc., No. 2017-1438 (Fed. Cir. Oct. 24, 2017).
• Defensive value: This second IPR and its subsequent Federal Circuit affirmation further solidify the unpatentability of claims 1-10 of US7477410. The patent owner has repeatedly failed to defend these claims against obviousness challenges.

Strategic summary

All claims of US7477410 (claims 1-10) have been CANCELED through two separate Inter Partes Review proceedings, IPR2014-00539 and IPR2015-01178. Both decisions finding the claims unpatentable were affirmed by the U.S. Court of Appeals for the Federal Circuit. Therefore, there are no SUSTAINED or UNTESTED claims remaining in this patent. The patent, having expired in 2022-07-03, no longer holds any enforceable claims.

Regarding the estoppel landscape, since Unified Patents Inc. was the petitioner in both IPRs and successfully invalidated all claims, they and their privies would be estopped under 35 U.S.C. § 315(e)(2) from asserting in future district court or ITC proceedings that claims 1-10 are not invalid on any ground that Unified Patents raised or reasonably could have raised. For any other defendant, the prior art grounds (Kallin, Sasaki, Nishi combinations) used to invalidate claims 1-10 are still available as arguments if the claims were somehow to be reasserted (which is unlikely given the patent has expired and all claims were canceled).

A clear pattern signal here is that Unified Patents, an organization known for challenging low-quality patents, successfully invalidated all claims in two separate IPRs. The patent owner, MPHJ Technology Investments, LLC, aggressively pursued appeals to the Federal Circuit in both instances, indicating a strong desire to maintain the patent's validity. However, both appeals resulted in affirmations of the PTAB's invalidity findings, demonstrating the strength of the obviousness challenges.

Recommended next steps

Given that all claims (1-10) of US7477410 have been canceled and these decisions were affirmed by the Federal Circuit, and the patent has since expired, any demand letter citing these claims would be baseless. A defendant facing assertion of this patent should explicitly refer to the Final Written Decisions and the Federal Circuit affirmations.

The Final Written Decision for IPR2015-01178 can be found at: https://portal.unifiedpatents.com/ptab/case/IPR2015-01178

The Federal Circuit's affirmation for IPR2014-00539 is MPHJ Tech. Invs., LLC v. Unified Patents, Inc., No. 2015-2070 (Fed. Cir. Mar. 18, 2016).
The Federal Circuit's affirmation for IPR2015-01178 is MPHJ Tech. Invs., LLC v. Unified Patents, Inc., No. 2017-1438 (Fed. Cir. Oct. 24, 2017).

The disposition of the Federal Circuit for IPR2015-01178, for example, states: "Having considered the arguments and reviewed the record, we conclude that the Board's findings are supported by substantial evidence and that the Board did not err in its obviousness determination. Accordingly, we affirm." This confirms the cancellation of claims 1-10.
Since there are no active proceedings and all claims were cancelled, there are no ongoing trial-stage milestones to track.
The absence of any surviving claims means this patent no longer poses a threat of infringement.## Proceedings overview
