PTAB challenges

Proceedings overview

There is one AIA trial proceeding on file for US patent 10664070, which is currently active. The proceeding is an Inter Partes Review (IPR) and its outcome will significantly influence the defensive posture for potential defendants.

IPR2022-00315 — SAMSUNG ELECTRONICS CO., LTD., AND SAMSUNG ELECTRONICS AMERICA, INC. v. Power2B, Inc.

• Type: Inter Partes Review
• Filed: 2021-12-14
• Status: Active (AIA trial proceeding filed before the Patent Trial and Appeal Board: inter partes review)
• Judge panel: Not publicly available at this time from the provided snippets.
• Petition grounds: Not publicly available at this time from the provided snippets.
• Institution decision: Not publicly available at this time from the provided snippets. (The "Final Written Decision" date of 2022-03-29 listed in the patent details is likely the date for a priority claim, not the FWD for this IPR. PTAB proceedings typically have a one-year statutory deadline for a Final Written Decision from institution, and this IPR was filed on 2021-12-14. Thus, an FWD would be expected around late 2022 if instituted.)
• Final Written Decision (if issued): Not yet issued.
• Settlement / termination: No settlement or termination information is publicly available at this time.
• Appeal: No appeal information is available as a Final Written Decision has not yet been issued.
• Defensive value: This active IPR proceeding indicates that the patentability of US10664070 is currently being challenged. A defendant facing assertion of this patent should closely monitor this IPR, as a decision to invalidate claims could significantly weaken the patent owner's position. Conversely, if claims are sustained, it may indicate a stronger patent.

Strategic summary

As of today, June 26, 2026, the patent US10664070 has one active Inter Partes Review, IPR2022-00315, filed by [[Samsung Electronics Co.](/litigations/by-defendant/Samsung%20Electronics%20Co.), Ltd.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.), and Samsung Electronics America, Inc. Since the Final Written Decision has not yet been issued, it is not possible to definitively state which claims are CANCELED vs. SUSTAINED vs. UNTESTED. All 18 claims of the patent are currently under review in this IPR.

The estoppel landscape for IPR2022-00315 is still developing. If the IPR proceeds to a Final Written Decision, the petitioners (Samsung entities) and their privies would be estopped under 35 U.S.C. § 315(e)(2) from raising any ground that they raised or reasonably could have raised during the IPR. For other potential defendants, the prior-art grounds available would depend on the specific grounds asserted in IPR2022-00315 and the ultimate outcome. Unified Patents has a case filed related to this patent, IPR2022-00315, indicating a potential defensive aggregator involvement in challenging the patent.

Recommended next steps

The IPR2022-00315 is ongoing. For a defendant facing assertion of this patent, it is crucial to monitor the progress of this IPR. The institution decision, if not yet public, is the next significant milestone, followed by the oral hearing, and then the Final Written Decision. The PTAB has a statutory one-year deadline for the Final Written Decision from the date of institution. Information on the proceeding can be found on the USPTO PTAB E2E system.
