Untitled case

A patent infringement lawsuit, SnapAid, Ltd. v. Samsung Electronics Co., Ltd. et al., is currently active in the U.S. District Court for the Eastern District of Texas, Marshall Division, under case number 2:25-cv-00378. The plaintiff, SnapAid, Ltd., has asserted U.S. Patent No. 12,250,452, along with seven other closely related patents, all generally titled "Real Time Assessment of Picture Quality." These patents pertain to systems and methods designed to perform real-time image quality analysis and provide immediate feedback to users during photo and video capture. The defendants are Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc.. The litigation arose after SnapAid engaged in discussions with Samsung regarding a potential partnership to enhance cell-phone picture quality, sharing proprietary technical materials under a Non-Disclosure Agreement. SnapAid alleges that after these discussions concluded without an agreement, Samsung subsequently released products incorporating the very capabilities SnapAid had disclosed, leading to the infringement claims. This suggests that Samsung's mobile phone camera technology or related features are the accused products. While one source identifies SnapAid as a "Patent Owner" and "Operating Company," Samsung's motion to stay describes SnapAid as having "no apparent business operations other than asserting its patent portfolio," implying it may function as a Non-Practicing Entity (NPE) or Patent Assertion Entity (PAE).

The case is presided over by District Judge Robert W. Schroeder III, with Magistrate Judge Roy S. Payne handling pretrial matters. The Eastern District of Texas is a frequent venue for patent litigation, often referred to as a "rocket docket" due to its rapid litigation timetables, and is perceived by many patentees as a favorable forum due to its local rules and a jury pool believed to be sympathetic to plaintiffs. This preference has contributed to its historical popularity, and the district has recently seen a resurgence in patent filings, partly attributed to judges' extensive experience with patent cases and commitment to swift trials.

The litigation is notable for its parallel proceedings at the Patent Trial and Appeal Board (PTAB), where Samsung has filed Post-Grant Review (PGR) petitions challenging the validity of five of the eight asserted patents, including patent 12,250,452. Samsung's petitions specifically target patents issued within the last six years, which are eligible for PGR. SnapAid has requested the PTAB to deny institution of these reviews, arguing that the district court trial, scheduled for April 2027, will address similar issues, and a PTAB final written decision would offer only a marginal timing benefit. The PTAB proceedings have also involved disputes over the effective filing date of patent 12,250,452 and its eligibility for post-grant review. The ongoing debate about the nature of SnapAid's business operations and the IPR challenges against a major electronics company like Samsung in a plaintiff-friendly venue like the Eastern District of Texas highlight common patterns in modern patent litigation.

SnapAid, Ltd. v. Samsung Electronics Co., Ltd. et al (2:25-cv-00378) is an active patent infringement case in the Eastern District of Texas concerning U.S. Patent 12,250,452, among others. The lawsuit was filed by SnapAid, Ltd. against Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc.

Here's a breakdown of the key legal developments:

1. Filing & Initial Pleadings:

• Complaint Filed: SnapAid, Ltd. filed its complaint on April 10, 2025, asserting infringement of eight related U.S. patents, including 12,250,452. All asserted patents share a common specification and relate to real-time assessment of picture quality.
• Docket Control Order: On September 24, 2025, the court issued an Agreed Docket Control Order and a Discovery Order.

2. Pre-trial Motions of Substance:

• Motion for Extension of Deadlines: An order granting a motion for extension of deadlines was signed on August 27, 2025.
• Motion to Stay Pending Ex Parte Reexamination: On May 12, 2026, Samsung Electronics America, Inc. and Samsung Electronics Co., Ltd. filed a motion to stay the case pending ex parte reexamination of certain patents. This motion argued that reexamination of patents like '226, '537, and '682 had been ordered based on significant new questions of patentability (SNQs) in light of prior art not considered during original prosecution. Samsung highlighted that the Markman hearing was still several months away, and other significant events like expert discovery and summary judgment briefing were also distant, with trial scheduled for April 2027.
• Motion to Amend Infringement Contentions: On May 13, 2026, the court granted SnapAid's unopposed motion for leave to amend its infringement contentions to supplement P.R. 3-2 disclosures. SnapAid stated it had uncovered previously undiscovered documents relevant to the reduction to practice and conception of the patents-in-suit.

3. Claim Construction (Markman) Outcomes:

• A Markman Hearing is scheduled for October 22, 2026, before Magistrate Judge Roy S. Payne. Markman briefing on indefiniteness is due in September 2026.

4. Discovery Milestones:

• A Discovery Order was signed on September 24, 2025.
• Fact discovery in this case is set to close on November 16, 2026.

5. Parallel PTAB IPR/PGR Proceedings:

• Samsung initiated several Post-Grant Review (PGR) and Inter Partes Review (IPR) proceedings at the USPTO against patents related to the litigation.
• Specifically, a PGR proceeding (PGR2025-00083) was initiated for U.S. Patent 12,250,452. Samsung has also challenged patents 9,661,226 ('226 Patent), 10,659,682 ('682 Patent), and 11,671,702 ('702 Patent) in IPR/PGR proceedings. Patents 9,338,348 ('348 Patent), 9,661,226 ('226 Patent), and 10,009,537 ('537 Patent) were not challenged in post-grant proceedings.
• In November 2025, SnapAid filed a Patent Owner's Request for Discretionary Denial in PGR2025-00083, arguing against institution of the PGR. SnapAid argued that the district court case involves eight closely related patents, and the Eastern District of Texas would resolve infringement, validity, and damages for all of them in April 2027. SnapAid contended that a Final Written Decision from the PTAB, if review were instituted on some patents, would only issue one month before trial, offering no meaningful efficiency gains and risking inconsistent outcomes.
• In January 2026, SnapAid filed a Patent Owner's Sur-Reply in PGR2025-00083, addressing Samsung's allegedly inconsistent positions on claim indefiniteness in the district court versus the PGR.
• Reexamination of the '226, '537, and '682 patents has been ordered due to findings of SNQs based on prior art not initially considered.

Present Posture:

• The case is active. A Pretrial Conference is set for March 15, 2027, and a Jury Selection is set for April 19, 2027, before District Judge Robert W. Schroeder III. The Markman Hearing is scheduled for October 22, 2026.
