Case Overview and Background for Network-1 Technologies, Inc. v. Samsung Electronics Co., Ltd. et al.

This patent infringement litigation, Case No. 2:25-cv-00667, is currently pending in the U.S. District Court for the Eastern District of Texas, Marshall Division, before District Judge Rodney Gilstrap. The plaintiff, Network-1 Technologies, Inc., is a publicly traded patent licensing entity (NPE) focused on the acquisition, development, licensing, and protection of intellectual property assets. Network-1 Technologies acquires patent portfolios from various sources, including individual inventors and other companies, to monetize them through licensing and litigation. The defendants are Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc., global technology companies known for manufacturing a wide range of electronic products, including semiconductor memory products.

The case concerns alleged infringement of intellectual property related to technology from the M2M/IoT patent portfolio, which Network-1 acquired through a series of transactions from M2M and IoT Technologies, LLC, an IP development company. The accused products or technologies are generally related to Samsung's semiconductor memory products and DRAM devices. While the case metadata provided specifies patent 11916893 as at issue, public court records and legal news for case 2:25-cv-00667 consistently indicate that Network-1 Technologies is asserting other patents against Samsung, specifically referencing patent 12166869 and a portfolio of six patents from M2M and IoT Technologies, LLC. Given the instruction to prioritize the provided metadata, the patent at issue for this overview is U.S. Patent No. 11916893, which generally relates to [A one-line technical sketch of 11916893 will be inserted here after a USPTO search for the patent abstract].

The procedural posture of the case shows it was filed on June 27, 2025, and is actively progressing through the Eastern District of Texas, a well-known venue for patent litigation due to its specialized docket and perceived plaintiff-friendly reputation. Judge Rodney Gilstrap, a highly experienced patent judge, is presiding over the case, with a Markman hearing scheduled for December 14, 2026, and jury selection for June 7, 2027. This litigation is notable as part of Network-1's ongoing strategy to monetize its acquired patent portfolios and reflects a pattern of NPE assertion in the technology sector. Samsung, as a major player in the memory market, is a frequent target in patent disputes, and has faced significant patent infringement verdicts in the Eastern District of Texas in related cases involving memory technology, such as those brought by Netlist (a distinct plaintiff from Network-1).

Note on Patent 11916893: A direct search for U.S. Patent No. 11916893 on the USPTO website and other patent databases (such as Justia Patents) does not yield an active or issued patent with this number as of May 29, 2026. This suggests that the provided patent number may be incorrect, or it might refer to a pending application or an international patent that is not easily identifiable through standard U.S. patent search tools. Without an active or published U.S. patent with this number, a one-line technical sketch cannot be provided based on public records. Therefore, I must explicitly state that the technical sketch for patent 11916893 cannot be provided as the patent does not appear to be publicly available via USPTO search.

Given the strong contradiction, I must explicitly state this.

Revised Sentence for Patent:
While the case metadata provided specifies U.S. Patent No. 11916893 as at issue, publicly available records for this case consistently identify U.S. Patent No. 12166869 and other patents from the M2M/IoT portfolio as being asserted. As of May 29, 2026, U.S. Patent No. 11916893 does not appear to be an issued or published patent in the United States Patent and Trademark Office (USPTO) database, therefore a technical sketch cannot be provided.This patent infringement litigation, case number 2:25-cv-00667, is pending in the U.S. District Court for the Eastern District of Texas, Marshall Division, before District Judge Rodney Gilstrap. The plaintiff, Network-1 Technologies, Inc., is a publicly traded patent licensing entity (NPE) whose business model involves the acquisition, development, licensing, and protection of intellectual property assets.

The dispute centers on alleged infringement of technology related to semiconductor memory products and DRAM devices, specifically memory modules. While the case metadata provided for this analysis specifies U.S. Patent No. 11916893 as at issue, publicly available court records and legal news for case 2:25-cv-00667 consistently indicate that Network-1 Technologies is asserting other patents from its M2M/IoT portfolio against Samsung, notably U.S. Patent No. 12166869. As of May 29, 2026, U.S. Patent No. 11916893 does not appear as an issued or published patent in the United States Patent and Trademark Office (USPTO) database, and therefore, a specific one-line technical sketch cannot be provided based on public records.
