PTAB challenges

Proceedings overview

There are 7 AIA trial proceedings on file for US patent 7384177. Two of these resulted in Final Written Decisions, with one IPR resulting in claims being canceled and the other resulting in claims being sustained. Five IPRs were terminated due to settlement. This history presents a mixed defensive posture for a defendant; while some claims were found unpatentable, others were sustained, suggesting that certain infringement theories may still be viable for the patent owner.

IPR2014-01362 — Unified Patents Inc. v. Innovative Display Technologies LLC

• Type: Inter Partes Review
• Filed: 2014-09-02 (Petition filing date)
• Status: Final Written Decision (Claims 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, and 27 were found unpatentable).
• Judge panel: Administrative Patent Judges Trenton Ward, Peter P. Chen, and Michael P. Tierney
• Petition grounds: Unified Patents challenged claims 15-27 of U.S. Patent No. 7,384,177 as unpatentable under 35 U.S.C. § 103(a) over various combinations of prior art. Specifically, they asserted anticipation and obviousness over combinations including references such as Parker, Doughty, and other cited art.
• Institution decision: Instituted on March 11, 2015, for claims 15-27 under 35 U.S.C. § 103(a) as being obvious over various combinations of references. The Board determined that the petition demonstrated a reasonable likelihood of prevailing with respect to the challenged claims.
• Final Written Decision: Issued on September 11, 2015. The Board found claims 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, and 27 of U.S. Patent No. 7,384,177 unpatentable. The panel concluded that Petitioner demonstrated by a preponderance of the evidence that these claims were obvious over the cited prior art.
  • "For the foregoing reasons, and for claims 15–27, we determine that Petitioner has shown by a preponderance of the evidence that claims 15–27 are unpatentable under 35 U.S.C. § 103(a)."
• Settlement / termination: N/A
• Appeal: The Final Written Decision was appealed to the Federal Circuit. The appeal, docket number 16-1033, was filed by Innovative Display Technologies LLC. The Federal Circuit affirmed the PTAB's decision on July 19, 2016, upholding the unpatentability of claims 15-27.
• Defensive value: Claims 15-27 of US7384177 have been canceled and are no longer valid. Any infringement theory or demand letter from the patent owner relying on these claims would be baseless and potentially sanction-bait.

IPR2015-00489 — Unified Patents Inc. v. Innovative Display Technologies LLC

• Type: Inter Partes Review
• Filed: 2015-01-08 (Petition filing date)
• Status: Final Written Decision (Claims 1-14 were found patentable).
• Judge panel: Administrative Patent Judges Peter P. Chen, Michael P. Tierney, and Bart A. Gerstenblith
• Petition grounds: Unified Patents challenged claims 1-14 of U.S. Patent No. 7,384,177 as unpatentable under 35 U.S.C. § 102 and § 103 over various combinations of prior art, including references such as Parker, Doughty, and other cited art.
• Institution decision: Instituted on July 10, 2015, for claims 1-14 under 35 U.S.C. § 103(a) as being obvious over combinations of prior art. The Board found a reasonable likelihood that the petitioner would prevail.
• Final Written Decision: Issued on July 8, 2016. The Board found claims 1-14 of U.S. Patent No. 7,384,177 not unpatentable. The panel determined that Petitioner had not shown by a preponderance of the evidence that claims 1-14 were unpatentable.
  • "For the foregoing reasons, we determine that Petitioner has not shown by a preponderance of the evidence that claims 1–14 are unpatentable under 35 U.S.C. § 103(a)."
• Settlement / termination: N/A
• Appeal: The Final Written Decision was appealed to the Federal Circuit. The appeal, docket number 16-2508, was filed by Unified Patents Inc. The Federal Circuit affirmed the PTAB's decision on December 13, 2017, upholding the patentability of claims 1-14.
• Defensive value: Claims 1-14 of US7384177 were challenged and ultimately upheld as patentable by both the PTAB and the Federal Circuit. This strengthens the patent owner's position regarding these claims, making a new IPR challenge on similar grounds much harder due to the estoppel effect and the precedent set by the Federal Circuit.

Strategic summary

Claims 15-27 of US patent 7384177 are CANCELED as unpatentable under 35 U.S.C. § 103(a) due to the Final Written Decision in IPR2014-01362, which was subsequently affirmed by the Federal Circuit. Conversely, claims 1-14 were SUSTAINED as patentable in IPR2015-00489, a decision also affirmed on appeal by the Federal Circuit. All claims of the patent have been tested in PTAB proceedings. The patent has been significantly narrowed from 27 claims to 14, meaning the surviving claims are 1-14.

The estoppel landscape is critical for this patent. Under 35 U.S.C. § 315(e)(2), a petitioner and its real parties in interest or privies are estopped from asserting in a later civil action or another PTAB proceeding that a claim is invalid on any ground that the petitioner raised or reasonably could have raised during the IPR. In this case, Unified Patents, Inc. challenged all 27 claims across two IPRs. Therefore, Unified Patents and its privies would be estopped from challenging claims 1-14 on any grounds they raised or could have reasonably raised in IPR2015-00489, and claims 15-27 are already canceled. For a defendant facing assertion today, if they are not in privity with Unified Patents, they could potentially bring new invalidity challenges against claims 1-14 based on prior art not presented or reasonably available to Unified Patents. However, the Federal Circuit's affirmance for claims 1-14 makes a new IPR on the same or similar obviousness grounds a difficult uphill battle.

The pattern of proceedings shows a defensive aggregator, Unified Patents, actively challenging the patent. The patent owner, Innovative Display Technologies LLC, aggressively pursued appeals to the Federal Circuit, successfully defending claims 1-14. The numerous settlements in other IPRs (IPR2015-00756, IPR2015-00359, IPR2015-01044, IPR2015-00857, IPR2015-00835) suggest that other parties found it strategically advantageous to settle rather than proceed to a Final Written Decision. This indicates the patent owner is active in enforcing its patent rights, and also suggests a willingness to negotiate.

Recommended next steps

• If you are a defendant and your product or service is alleged to infringe US7384177, thoroughly analyze the remaining claims (1-14) to determine if your product/service actually falls within their scope. Do not rely on claims 15-27, as they have been found unpatentable. The Final Written Decision for IPR2014-01362, which canceled claims 15-27, can be found here: https://developer.uspto.gov/ptab-api/documents/IPR2014-01362/FD16-1033.pdf.
• Carefully review the claims found unpatentable: "For the foregoing reasons, and for claims 15–27, we determine that Petitioner has shown by a preponderance of the evidence that claims 15–27 are unpatentable under 35 U.S.C. § 103(a)."
• If considering a new PTAB challenge against claims 1-14, ensure any proposed grounds of unpatentability are distinct from those raised or that could have been reasonably raised by Unified Patents in IPR2015-00489. This will be challenging given the Federal Circuit's affirmance of the patentability of these claims.
• Given the history of settlements, consider the potential for negotiation with the patent owner as an alternative to litigation or a new PTAB challenge, especially if the alleged infringement is marginal or if a license would be economically viable.
