Samsung Electronics Co., Ltd. et al. v. Staton Techiya, LLC

Samsung Electronics Co., Ltd. and its subsidiary, Samsung Electronics America, Inc., are global operating companies recognized as leaders in consumer electronics, mobile devices, home appliances, and technology solutions. Samsung Electronics Co., Ltd. is a South Korean multinational corporation, and Samsung Electronics America, Inc. serves as its major U.S. subsidiary, specializing in a wide range of products including smartphones, TVs, and IT solutions. On the other side of this dispute is Staton Techiya, LLC, identified as a patent assertion entity (PAE) or non-practicing entity (NPE). Staton Techiya was formed in Delaware in June 2017 and is connected with Staton Capital, a private equity investment firm, which advertises investments in Techiya, describing the company as having developed "hands-free, error-free communication through its patented micro-balloon SmartBud earpiece technology" and owning a portfolio of patents supporting this technology.

This case, IPR2022-00282, is an Inter Partes Review (IPR) filed by Samsung against Staton Techiya concerning U.S. Patent 8,315,400. The procedural posture places this dispute before the Patent Trial and Appeal Board (PTAB) of the U.S. Patent and Trademark Office (USPTO). The PTAB provides an administrative forum for challenging the patentability of claims in an issued patent, offering a quicker and potentially more cost-effective alternative to district court litigation for resolving patent validity disputes. This venue is significant as it allows parties to address validity outside of lengthy and expensive court proceedings, potentially influencing ongoing or future patent infringement assertions.

While specific details regarding the accused products in relation to IPR2022-00282 and the '400 patent are not explicitly detailed in the provided search results, Staton Techiya has previously asserted patents against Samsung relating to audio processing, voice-based AI, and personalized sound technologies, targeting a broad range of Samsung's consumer electronics, including Galaxy smartphones, Galaxy Buds earphones, tablets, watches, and smart TVs in related district court litigation. The '400 patent itself is generally directed to aspects of personalized hearing. The case is notable as it represents Samsung's active use of the IPR process to challenge the validity of patents asserted by NPEs like Staton Techiya, a common strategy by operating companies to mitigate patent infringement risks. This IPR, culminating in a Final Written Decision, highlights the ongoing efforts of technology companies to leverage administrative patent challenges against entities primarily engaged in patent assertion.

The initial search has yielded comprehensive details about the district court litigation (2:21-cv-00413) and the Federal Circuit appeals (23-2292 and 23-2290) related to IPR2022-00282, which involves patent 8315400.

Here's a breakdown of what has been confirmed and what remains to be found:

District Court Litigation (Staton Techiya, LLC v. Samsung Electronics Co., Ltd., 2:21-cv-00413 E.D. Tex.)

• Filing & Initial Pleadings: Staton Techiya, LLC and Synergy IP Corporation filed a patent infringement lawsuit against Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. on November 5, 2021. Patent 8,315,400 ("the '400 patent") was among the ten patents initially asserted in this complaint. A second related lawsuit (2:22-cv-00053) asserting four additional patents was also filed on February 14, 2022, and later consolidated with the lead case.
• Pre-trial Motions/Discovery: Samsung asserted an "unclean hands" defense, alleging that Staton Techiya's litigation partner, Synergy IP Corporation (controlled by former Samsung employees Dr. Seungho Ahn and Mr. Sungil Cho), had used stolen Samsung privileged information concerning the asserted patents. This defense was adjudicated in a bench trial.
• Trial Events, Verdict, and Post-trial Motions: A bench trial on Samsung's equitable defenses and non-patent counterclaims was held on March 26 and 27, 2024. On May 9, 2024, the Court issued its Findings of Fact and Conclusions of Law, finding that Staton Techiya's asserted patent claims, including potentially 8315400, were unenforceable against Samsung based on unclean hands. The Court dismissed Techiya's patent claims with prejudice and entered a Final Judgment, awarding Samsung its costs as the prevailing party. On August 29, 2024, the Court issued a Memorandum Opinion and Order addressing Samsung's motion for a Bill of Costs. This outcome effectively ended the infringement litigation on the asserted patents in district court, not on the merits of infringement or invalidity, but due to Staton Techiya's misconduct.

Parallel PTAB IPR Proceedings (IPR2022-00282 for Patent 8315400)

• Filing & Institution: Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. filed a petition for Inter Partes Review (IPR2022-00282) challenging U.S. Patent No. 8,315,400. The IPR was instituted on July 14, 2022.
• Final Written Decision: The prompt indicates "Status: Final Written Decision." However, the exact date and, more importantly, the outcome of the Final Written Decision for IPR2022-00282 regarding the patentability of claims of U.S. Patent No. 8,315,400 have not been explicitly found. While some sources note that the PTAB's decision became the "last substantive ruling of record" after the Federal Circuit appeals, the details of that decision (e.g., which claims were found unpatentable, which survived) are not yet available.

Federal Circuit Appeals

• Appeal No. 23-2292 (Samsung's cross-appeal from IPR2022-00282): Samsung filed this appeal on August 17, 2023. It was voluntarily dismissed via a joint stipulation with Staton Techiya on January 29, 2025. No merits ruling was issued by the Federal Circuit, and each side bore its own costs.
• Appeal No. 23-2290 (Staton Techiya's appeal from IPR2022-00282): This appeal was also initiated from the PTAB's decision in IPR2022-00282. After Samsung's cross-appeal (23-2292) was dismissed, Appeal No. 23-2290 remained active, with Staton Techiya's principal brief being transmitted to the merits panel. The final disposition of this appeal is still needed.

The critical missing pieces are the specific outcome of the Final Written Decision for IPR2022-00282 and the ultimate disposition of Federal Circuit Appeal No. 23-2290.

Since P-TACTS is the USPTO's system for tracking PTAB cases and decisions, a direct search there, if possible, would be the most effective way to get the Final Written Decision details. However, direct P-TACTS links are usually not provided in general web searches, and direct access often requires a sign-in. Given I cannot directly interact with a system that requires a sign-in, I will attempt to find published summaries or legal updates that report the FWD outcome for IPR2022-00282 and the final disposition of CAFC 23-2290.

I will conduct one more search to try and pin down these remaining details.I have gathered most of the requested information, but the specific outcome of the Final Written Decision for IPR2022-00282 is still missing details beyond it being "the last substantive determination of record on US8315400B2's validity". I also need the final disposition of Federal Circuit Appeal No. 23-2290.

Direct access to PTAB documents via P-TACTS is not available through web search, and general search results often summarize or refer to the existence of decisions rather than providing their full content or detailed claim-by-claim outcomes.

Let me try one more specific search for the IPR2022-00282 Final Written Decision outcome and the CAFC 23-2290 disposition. If I still cannot find the precise claim-by-claim outcome of the FWD, I will state that the exact details are not publicly available in the search results but that the PTAB's decision is the operative one.## Samsung Prevails in Patent Disputes Against Staton Techiya, Marked by "Unclean Hands" Defense and IPR Challenges

Washington, D.C. – June 19, 2026 – Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. successfully defended against patent infringement claims brought by Staton Techiya, LLC, primarily through an "unclean hands" defense in district court litigation and Inter Partes Review (IPR) proceedings at the Patent Trial and Appeal Board (PTAB) concerning U.S. Patent No. 8,315,400. While the IPR concluded with a Final Written Decision and spawned Federal Circuit appeals, the underlying district court case resulted in a decisive judgment for Samsung based on equitable grounds.

Key Legal Developments and Outcome:

1. District Court Litigation: Staton Techiya, LLC v. Samsung Electronics Co., Ltd. et al. (E.D. Tex., Case No. 2:21-cv-00413)

• Filing & Initial Pleadings (2021-11-05): Staton Techiya, LLC and Synergy IP Corporation initiated a patent infringement lawsuit against Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. in the U.S. District Court for the Eastern District of Texas. U.S. Patent No. 8,315,400 ("the '400 patent") was among the ten patents asserted in this initial complaint. A second, related lawsuit (Case No. 2:22-cv-00053), asserting four additional patents, was filed on February 14, 2022, and subsequently consolidated with the lead case.
• Pre-Trial Motions & Discovery (Leading to "Unclean Hands"): Samsung raised an "unclean hands" affirmative defense, alleging that Staton Techiya's litigation partner, Synergy IP Corporation, controlled by former Samsung employees Dr. Seungho Ahn and Mr. Sungil Cho, had improperly used privileged Samsung information related to the asserted patents. This discovery became a central focus of the litigation.
• Trial Events & Verdict (2024-05-09): A bench trial addressing Samsung's equitable defenses and non-patent counterclaims took place on March 26 and 27, 2024. On May 9, 2024, the Court issued its Findings of Fact and Conclusions of Law, determining that Staton Techiya's asserted patent claims were unenforceable against Samsung based on unclean hands. The Court dismissed Techiya's patent claims with prejudice.
• Post-Trial Motions & Judgment (2024-08-29): A Final Judgment was entered awarding Samsung its costs as the prevailing party. On August 29, 2024, the Court issued a Memorandum Opinion and Order addressing Samsung's motion for a Bill of Costs. The outcome in the district court did not hinge on a merits-based finding of infringement or validity, but rather on Staton Techiya's and its partner's misconduct.

2. Parallel PTAB IPR Proceedings: Samsung Electronics Co., Ltd. et al. v. Staton Techiya, LLC (IPR2022-00282)

• Filing (2021-12-20): Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. filed a petition for Inter Partes Review (IPR2022-00282) challenging the patentability of claims in U.S. Patent No. 8,315,400.
• Institution (2022-07-14): The PTAB instituted review of the '400 patent.
• Final Written Decision (FWD): The PTAB issued its Final Written Decision for IPR2022-00282. While the exact date and specific claim-by-claim outcome were not readily available in public summaries, this decision became the "last substantive determination of record on US8315400B2's validity" following the subsequent dismissal of appeals. It is understood that the IPR process typically concludes with a decision confirming, canceling, or allowing amended claims based on anticipation or obviousness.

3. Federal Circuit Appeals from IPR2022-00282

• Samsung's Cross-Appeal (CAFC No. 23-2292): Samsung filed Appeal No. 23-2292 at the Court of Appeals for the Federal Circuit on August 17, 2023, stemming from the PTAB's decision in IPR2022-00282. This appeal was voluntarily dismissed via a joint stipulation with Staton Techiya on January 29, 2025. No merits ruling on the patentability was issued by the Federal Circuit, and each side bore its own costs.
• Staton Techiya's Appeal (CAFC No. 23-2290): Staton Techiya also filed an appeal (Appeal No. 23-2290) from the PTAB's Final Written Decision in IPR2022-00282. After Samsung's cross-appeal (23-2292) was dismissed, Appeal No. 23-2290 remained active, with Staton Techiya's principal brief transmitted to the merits panel. However, public records do not indicate a final merits decision for this appeal. Given the comprehensive dismissal of infringement claims due to "unclean hands" in the district court and the voluntary dismissal of Samsung's cross-appeal, it is likely that Staton Techiya's appeal may have also been resolved through a non-merits disposition or became moot, though specific details of its final outcome are not publicly available in the provided search results.

Final Disposition:

The primary patent infringement litigation (2:21-cv-00413) concluded with a judgment in favor of Samsung, finding Staton Techiya's asserted patents, including 8,315,400, unenforceable due to unclean hands. The parallel IPR (IPR2022-00282) resulted in a Final Written Decision by the PTAB regarding the patentability of claims of U.S. Patent No. 8,315,400, which, despite appeals, stands as the operative determination on validity. Samsung's related Federal Circuit cross-appeal was voluntarily dismissed.

Based on available information from related proceedings and firm profiles, the following counsel are likely to have represented Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. as plaintiff(s) in IPR2022-00282. While a specific docket entry directly listing "Lead and Back-up Counsel" for this exact IPR and naming them was not fully extracted in the search snippets, strong inferences can be made from related cases and general firm representation of Samsung in PTAB matters.

Identifying the counsel of record for Staton Techiya, LLC in IPR2022-00282 proved challenging through direct searches for that specific IPR. However, information from related cases and appeals involving Staton Techiya and Samsung provides insight into their typical legal representation in patent disputes.

While a definitive list of counsel for this specific IPR was not immediately available in the search results, information from other related PTAB proceedings and Federal Circuit appeals involving Staton Techiya and Samsung offers strong indications. One related IPR, IPR2022-00281, lists "Snodgrass, Jacob et al." as Respondent Counsel (for Staton Techiya). Jacob Snodgrass is a patent litigation attorney. Given the close nature of the IPRs (IPR2022-00281 and IPR2022-00282, both filed by Samsung against Staton Techiya around the same time and concerning related technologies), it is highly probable that similar counsel represented Staton Techiya in IPR2022-00282.

In other Federal Circuit appeals related to PTAB decisions involving Staton Techiya and Samsung (e.g., Case No. 23-2290 and 23-2292 for IPR2022-00282, and Case No. 23-2294 for IPR2022-00234), Staton Techiya appeared as the appellant or appellee. These appellate filings would necessitate legal representation.

Additionally, Staton Techiya has been involved in district court litigation against Samsung, where they were represented by counsel. In one such case (2:21-cv-00413 in the Eastern District of Texas), Staton Techiya, alongside Synergy IP Corporation, was represented by attorneys. Synergy IP, founded by former Samsung lawyers Seungho Ahn and Sungil Cho, acted as a litigation agent for Staton Techiya and was involved in lawsuits against Samsung. While Ahn and Cho were named as additional defendants in counterclaims by Samsung in a related district court case, alleging trade secret misappropriation, their specific role as counsel of record in the IPRs is not explicitly stated.

Based on the available information, while specific roles (lead, of counsel, local) for IPR2022-00282 are not detailed, it is highly likely that Jacob Snodgrass was among the counsel representing Staton Techiya at the PTAB. His firm and specific experience would require further investigation beyond the immediate search results.

It is worth noting that a district court case (2:21-cv-00413) brought by Staton Techiya against Samsung was dismissed due to "unclean hands" based on evidence of former Samsung lawyers (Seungho Ahn and Sungil Cho, who later founded Synergy IP) obtaining privileged information for use in the suit. This, while a separate district court matter, highlights the broader litigation landscape surrounding Staton Techiya's patent assertions and the involvement of various legal entities.
