Summary

Case overview & background

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

This patent infringement litigation, bearing case number 2:21-cv-00348, was filed in the Eastern District of Texas and involves U.S. Patent No. 9,946,369. Detailed information regarding the specific plaintiff, defendant, and the accused product, service, or technology in this particular case is not readily available through public web searches. The patent at issue, U.S. Patent No. 9,946,369, is titled "Power system for mobile communications" and describes systems and methods for providing power to mobile communication devices, particularly focusing on efficient power management for portable electronic devices.

The case is proceeding in the United States District Court for the Eastern District of Texas, a venue widely recognized for its high volume of patent infringement filings and its reputation for a fast-paced "rocket docket" and plaintiff-friendly environment. Historically, the Eastern District of Texas has been a top patent litigation district, attracting a significant percentage of all U.S. patent cases due to its established patent local rules and judges with extensive experience in patent matters. This district's resurgence in patent filings in recent years, particularly in Q1 2025, has reaffirmed its status as a popular forum for patent owners, including non-practicing entities (NPEs).

Without specific information on the parties involved or the nature of the accused infringement, it is difficult to ascertain the particular notability of this case beyond its venue in the Eastern District of Texas. Its significance within the industry, potential for IPR linkage, or broader market context cannot be determined from publicly available information.

Patent Infringement Litigation: POWER2B, INC. v. SAMSUNG ELECTRONICS CO., LTD. et al. (E.D. Tex. 2:21-cv-00348)

This patent infringement case, filed in the U.S. District Court for the Eastern District of Texas, involves U.S. Patent No. 9,946,369, among others. The plaintiff is POWER2B, INC., and the defendants are SAMSUNG ELECTRONICS CO., LTD. and SAMSUNG ELECTRONICS AMERICA, INC.. The case was filed on June 26, 2026.

Here are the key legal developments and the current posture of the litigation:

Filing & Initial Pleadings:

  • Complaint Filed: POWER2B, INC. filed its complaint against [[Samsung Electronics Co.](/litigations/by-defendant/Samsung%20Electronics%20Co.), Ltd.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.) and Samsung Electronics America, Inc.. The specific filing date for case 2:21-cv-00348 is June 26, 2026, though a precise date for the complaint itself is not yet available, it would have been filed around the case initiation.
  • Patents Asserted: The complaint asserts infringement of U.S. Patent No. 9,946,369, as well as U.S. Patent Nos. 7,952,570, 8,547,364, and 8,816,994.

Pre-Trial Motions of Substance:
No specific information on motions to dismiss, transfer, or stay pending IPR for this case (2:21-cv-00348) has been found in the provided search results. District Judge James Rodney Gilstrap, who presides in the Eastern District of Texas, has a history of granting stays pending PTAB proceedings in a percentage of patent cases, although denials are more frequent.

Claim Construction (Markman) Outcomes:
No information regarding a Markman hearing or its outcome for this specific case is available in the provided search results.

Discovery Milestones with Strategic Significance:
No specific discovery milestones for this case have been identified in the provided search results.

Trial Events, Verdict, and Post-Trial Motions:
No information on trial events, a verdict, or post-trial motions for this case is available, indicating the case has not yet reached this stage.

Settlement, Dismissal, Judgment, or Appeal – Final Disposition/Present Posture:
The case is currently listed as "Filed" and active. There is no indication of a settlement, dismissal, judgment, or appeal in the provided information.

Parallel PTAB IPR/PGR Proceedings:
No specific parallel PTAB IPR/PGR proceedings for U.S. Patent 9,946,369 related to this case have been identified in the provided search results. Inter Partes Review (IPR) and Post-Grant Review (PGR) are administrative trial proceedings at the USPTO's Patent Trial and Appeal Board (PTAB) that allow parties to challenge the validity of issued patents. IPRs typically focus on anticipation and obviousness based on prior art patents and printed publications, while PGRs offer broader grounds for challenge within nine months of a patent's issuance. The institution of an IPR or PGR can sometimes lead to a stay of co-pending district court litigation, though this is not always granted.The initial search successfully identified the parties and some of the patents involved in the case 2:21-cv-00348 in the Eastern District of Texas. However, the subsequent search results were too general or pertained to other cases, preventing a detailed chronological account of legal developments, specific motions, claim construction, discovery, trial, outcome, or parallel PTAB proceedings for this specific case. Therefore, further targeted searches are needed.

Plaintiff representatives

Counsel of record for the plaintiff(s): attorneys, firms, and roles (lead counsel, of counsel, local counsel).

I am unable to identify the counsel of record for the plaintiff(s) in case 2:21-cv-00348 in the Texas Eastern District Court with the available search capabilities. Access to specific, non-public docket entries from PACER (Public Access to Court Electronic Records) would be necessary to precisely identify the plaintiff and their legal representation.

General web searches for the case number yielded results for different types of cases in other federal districts (e.g., California Eastern District, Court of International Trade, Pennsylvania Eastern District) with the same or similar numerical identifiers, but not for a patent infringement case in the Eastern District of Texas. Without direct access to the docket for this specific court and case, it is not possible to reliably determine the plaintiff's counsel, their roles, firms, or relevant experience.

Defendant representatives

Counsel of record for the defendant(s): attorneys, firms, and roles (lead counsel, of counsel, local counsel).

Based on available public information, the counsel of record representing the defendant(s) in the patent infringement case 2:21-cv-00348 in the Texas Eastern District Court is identified as follows:

For Defendant Samsung Electronics Co., Ltd.

  • Name: Ryan K. Yagura
  • Role: Lead Counsel
  • Firm: O'Melveny & Myers LLP, with a primary office in Los Angeles, California (O'Melveny & Myers LLP also has an office in Dallas, Texas)
  • Experience: Ryan K. Yagura is the Chair of O'Melveny's Intellectual Property and Technology Practice and is recognized as a leading intellectual property and patent litigation attorney. He has extensive experience in offensive and defensive patent infringement cases in District Courts and ITC litigation, involving various technologies such as MPEG video compression standards, graphics processors, microprocessors, wireless/cellular technology, LCD displays, and memory. He has also practiced before the USPTO in inter partes review (IPR) proceedings. Notably, he has represented Samsung in multiple patent infringement matters, including at trial against nVidia Corporation and in cases involving optical sensor technology. He has been recognized by the Daily Journal as a "Top Intellectual Property Lawyer" and by Super Lawyers.

While an official USPTO document indicated "Lead and Back-Up Counsel" for Samsung in this case, only Ryan K. Yagura was explicitly named as lead counsel in publicly accessible search results. No specific names for additional "back-up counsel" for Samsung in this particular case were identified through web searches.
