Summary

An Inter Partes Review (IPR) case at the PTAB, resulting in a Final Written Decision.

Case overview & background

Plain-language overview of the case: parties, accused product, patents at issue, and why the suit matters.

The case IPR2021-01257, Petitioner v. Power2B Inc., is an Inter Partes Review (IPR) proceeding before the Patent Trial and Appeal Board (PTAB) concerning the validity of U.S. Patent No. 9,317,170 (the '170 patent).

The patent owner, Power2B Inc., describes itself as a "creative workshop dedicated to generating radical innovations in human experience" through advancements in user interface, products, and information technology, focusing on 3D input technology and interactive device technologies. They hold a portfolio of patents related to touchscreen interactions, electromagnetic sensors, and light-based input detection systems for electronic devices. The petitioner in this specific IPR was [[Samsung Electronics Co.](/litigations/by-defendant/Samsung%20Electronics%20Co.), Ltd.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.), a multinational technology company specializing in consumer electronics, semiconductors, and display technologies. Although the initial prompt stated "Petitioner," further search reveals Samsung's involvement, indicating that the original Petitioner in IPR2021-01257 was Samsung Electronics Co., Ltd..

The '170 patent is titled "Interactive Devices" and covers methods and devices for user interaction with touch-sensitive screens, particularly those relying on light-based sensing technologies. This technology provides absolute x-axis, y-axis, z-axis, and angle data from a light source for 3D input and hover capabilities, enabling advanced user interfaces for mobile devices, home entertainment, and presentation systems without requiring a physical touch-sensitive display.

This case's procedural posture is significant as it involves an IPR at the PTAB, a specialized administrative court for challenging patent validity. The PTAB's Final Written Decision regarding the '170 patent was subsequently appealed to the U.S. Court of Appeals for the Federal Circuit. In a February 12, 2025, decision, the Federal Circuit vacated and remanded the PTAB's initial decision, finding that the PTAB had improperly construed a key claim term: "impingement of an electromagnetic radiation spot." This misconstruction led to an erroneous determination that Samsung's cited prior art did not disclose the limitation, thereby reviving Samsung's obviousness challenge. More recently, a June 26, 2026 order from the Federal Circuit indicates that the proceeding, identified as Appeal No. 26-1654 originating from IPR2021-01257, was dismissed by agreement of the parties. This IPR is notable due to Power2B Inc.'s ongoing patent assertion activities, particularly against major technology companies like Samsung, and the Federal Circuit's involvement in clarifying claim construction standards in PTAB reviews.

Key legal developments & outcome

Major rulings, motions, claim construction, settlements, and the present posture or final disposition.

This case, IPR2021-01257, involved an Inter Partes Review (IPR) proceeding at the Patent Trial and Appeal Board (PTAB) challenging U.S. Patent No. 9,317,170, owned by Power2B Inc. Samsung Electronics Co., Ltd. acted as the Petitioner against Power2B Inc.

Key Legal Developments and Outcome:

  • IPR Petition Filing: Samsung Electronics Co., Ltd. filed a petition for inter partes review (IPR) against U.S. Patent No. 9,317,170, titled “Interactive Devices,” which is owned by Power2B Inc. The specific filing date of the petition could not be determined from public searches.
  • PTAB Institution Decision: The PTAB instituted the IPR proceeding. The exact date of the institution decision is not available through the conducted public searches. Typically, the PTAB issues an institution decision within approximately six months of the petition's filing.
  • PTAB Final Written Decision: Following institution, the PTAB issued a Final Written Decision. The precise date of this decision is not publicly available from the searches. This decision included a claim construction for the term “impingement of an electromagnetic radiation spot.”
  • Federal Circuit Appeal and Remand (2025-02-12): Samsung Electronics Co., Ltd. appealed the PTAB's Final Written Decision to the U.S. Court of Appeals for the Federal Circuit (Case No. 23-1630, Samsung Electronics Co., Ltd. v. Power2B, Inc.). On February 12, 2025, the Federal Circuit vacated and remanded the PTAB's decision. The appellate court determined that the PTAB had improperly construed the claim term “impingement of an electromagnetic radiation spot.” This erroneous construction led to an incorrect finding that Samsung’s cited prior art did not disclose the limitation at issue, necessitating a reevaluation of Samsung’s obviousness challenge under a corrected claim construction. [cite: 4 (previous search result)]
  • Subsequent Federal Circuit Dismissal (2026-06-26): After the Federal Circuit's remand, the case eventually returned to the Federal Circuit under a new appeal number, Appeal No. 2026-1654 (Power2B, Inc. v. Samsung Electronics Co., Ltd.). On June 26, 2026, the Federal Circuit issued an order dismissing the proceeding under Fed. R. App. P. 42(b). This dismissal was by agreement of the parties, with each side bearing its own costs. This indicates that Power2B and Samsung reached a settlement or another form of resolution following the remand, leading to the termination of the appeal.
