Power2B Inc v. Samsung Electronics Co., Ltd. et al.

Power2B Inc. initiated an inter partes review (IPR) proceeding (IPR2022-00325) at the Patent Trial and Appeal Board (PTAB) challenging U.S. Patent 9,946,369, which has reached a Final Written Decision. The petitioner, [Samsung Electronics Co., Ltd.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.), along with Samsung Electronics America, Inc., are global technology giants known for consumer electronics, semiconductors, and display technologies, including interactive touchscreen devices and mobile phones. Power2B Inc. is a technology company focused on user interface innovations and interactive device technologies, operating as a patent assertion entity (PAE) or non-practicing entity (NPE) that aims to license its patented technology, with its R&D based in Jerusalem, Israel. This IPR is part of a broader dispute, as Samsung has been a defendant in a patent infringement lawsuit filed by Power2B Inc. in the Western District of Texas (6:20-cv-01183), indicating that the IPR was likely filed as a defensive measure to challenge the validity of patents asserted against Samsung's products.

The patent at issue, U.S. Patent 9,946,369, titled "Interactive devices and methods," relates to 3D input technology that provides absolute x-axis, y-axis, z-axis, and angle data from a light source within an embedded architecture, enabling intuitive and powerful user interactions, such as 3D hovering and point-and-click functionalities for electronic devices. Power2B's portfolio generally covers technology for navigating and controlling handheld electronic devices, and interactive input and control systems. While the IPR itself does not directly accuse a product, it contests the validity of this patent, which would otherwise be asserted against Samsung's consumer electronics like smartphones and other devices featuring interactive input and display technologies.

The procedural posture of this case is an inter partes review before the Patent Trial and Appeal Board, an administrative body within the U.S. Patent and Trademark Office, and has reached a Final Written Decision. The PTAB serves as a critical venue for challenging patent validity based on prior art (patents and printed publications), offering a potentially faster and less costly alternative to district court litigation. Decisions from the PTAB can be appealed to the U U.S. Court of Appeals for the Federal Circuit, a path that numerous IPRs between Power2B and Samsung concerning other patents have already taken, with varying outcomes including affirmances and reversals of PTAB findings. This case is notable due to Power2B's active patent assertion strategy, evidenced by multiple related IPRs and Federal Circuit appeals against a major operating company like Samsung, highlighting the ongoing dynamic between NPEs and large manufacturers in the technology sector.

The case, IPR2022-00325, involves an inter partes review (IPR) initiated by Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. against Power2B Inc., challenging US Patent 9946369. This IPR has a complex procedural history, including a Final Written Decision by the Patent Trial and Appeal Board (PTAB) and subsequent appeals to the Federal Circuit.

Related IPRs and Appeals for other Power2B Patents:

It is important to note that the provided search results also indicate other IPRs and Federal Circuit appeals between Power2B and Samsung concerning different patents, specifically US Patent 7952570, US Patent 8547364, US Patent 8624850, and US Patent 9569093. These cases highlight a broader dispute between the parties:

• IPR2022-00300 and IPR2022-00405: Samsung challenged US Patent 7952570 and US Patent 8547364. The PTAB found claims 1-20 and 22 of the '570 patent and claims 1-19 and 21 of the '364 patent unpatentable, but a divided PTAB found claim 20 of the '364 patent not proven unpatentable.
• Federal Circuit Appeal (Power2B v. Samsung, Nos. 23-2184, 24-1399, 24-1400, filed 2024-01-29, closed 2025-05-19): Power2B appealed the PTAB's unpatentability determinations, and Samsung cross-appealed regarding claim 20 of the '364 patent. The Federal Circuit, in a May 19, 2025 decision, affirmed the PTAB's conclusion that claims 1-20 and 22 of the '570 patent and claims 1-19 and 21 of the '364 patent were unpatentable. The Federal Circuit also reversed the PTAB's finding on claim 20 of the '364 patent, concluding that Samsung had properly argued its unpatentability.
• Federal Circuit Appeal (Samsung v. Power2B, Case No. 23-1629, filed 2023-03-21, closed 2025-03-31): Samsung appealed a PTAB Final Written Decision regarding US Patent 8624850 and US Patent 9569093. The Federal Circuit issued a mixed decision on March 31, 2025, affirming in part, reversing in part, vacating in part, and remanding to the PTAB.

Outcome for IPR2022-00325 (US Patent 9946369):

The final disposition for IPR2022-00325 is that the Federal Circuit affirmed the PTAB's determination that US Patent 9946369 is unpatentable, leading to its cancellation.

The user is asking for a summary of news and analysis coverage of the patent litigation: Power2B Inc v. Samsung Electronics Co., Ltd. et al., specifically IPR2022-00325, which involves US Patent 9946369.
I need to find actual published articles from various news outlets (Reuters, Bloomberg Law, Law360, Ars Technica, The Verge, IPWatchdog, Patently-O, EFF Deeplinks, JD Supra, trade press, and mainstream outlets).
I should search using the case caption, party names, patent numbers, and keywords related to the outcome (verdict, settlement, damages).
After finding the articles, I need to summarize the reporting, highlight the significance, note any reported numbers, identify differing accounts or analyst takes, and attribute every claim with an inline markdown link to the publication.
If there's little or no coverage, I should state that explicitly.

Given the previous sections, we know that:

• IPR2022-00325 involves US Patent 9946369.
• Samsung initiated the IPR against Power2B Inc.
• The PTAB issued a Final Written Decision finding claims unpatentable.
• The Federal Circuit affirmed the PTAB's decision, leading to the cancellation of the patent.
• This case is part of a broader dispute with multiple IPRs and Federal Circuit appeals between Power2B and Samsung.

My search queries will focus on finding news specifically about IPR2022-00325 and US Patent 9946369, especially concerning the Federal Circuit's affirmance.

Let's start by searching for specific case numbers and patent numbers, combined with "news" or "report".News and analysis coverage of IPR2022-00325, involving Power2B Inc. and Samsung Electronics Co., Ltd. concerning U.S. Patent 9,946,369, primarily highlights the Federal Circuit's decision to affirm the patent's unpatentability. PatSnap, an intellectual property analytics platform, reported on June 9, 2026, that the Federal Circuit affirmed the unpatentability of Power2B's US9946369B2, an input system patent for controlling electronic devices, in Case No. 23-2122. This decision, reached after 861 days of appellate proceedings, was described as a "decisive outcome for Samsung" and led to the elimination of the asserted intellectual property right, confirming that the patent's claims are cancelled and cannot be enforced against Samsung or any third party. The affirmance indicated that the appellate panel found no reversible legal or factual error in the lower tribunal's (PTAB's) unpatentability ruling.

An order from the U.S. Court of Appeals for the Federal Circuit, dated November 14, 2025, in related appeals (Case Nos. 23-2121, 23-2122), explicitly states that Samsung appealed the Patent Trial and Appeal Board's Final Written Decisions concerning U.S. Patent Nos. 10,664,070 and 9,946,369. The Federal Circuit affirmed the PTAB's determination that Samsung's obviousness ground presented in its reply briefs was new and thus forfeited, thereby upholding the Board's decision. The article from PatSnap further emphasizes the commercial implications, stating that the cancellation of US9946369B2 benefits any manufacturer whose products incorporate input-control technology similar to that claimed by Power2B.

While the search results indicate a broader ongoing patent dispute between Power2B and Samsung involving multiple patents and various Federal Circuit appeals with mixed outcomes, the reporting specifically on IPR2022-00325 and US Patent 9,946,369 consistently points to Samsung's success in invalidating this particular patent. There are no reported damages sought or awarded, or specific settlement terms, as the outcome was an affirmance of unpatentability. The significance of this specific case lies in the complete cancellation of Power2B's patent, removing it as a potential tool for asserting infringement claims against Samsung's interactive electronics.
