Untitled case

This is an active patent infringement lawsuit, case number 2:25-cv-00430, filed in the Eastern District of Texas, involving prominent display technology companies. The plaintiff is Samsung Display Co. Ltd., a major South Korean manufacturer of display panels, while the defendants are BOE Technology Group Co., Ltd., a Chinese multinational electronics company, and potentially its affiliates. Both parties are operating companies, making this a dispute between competitors in the display industry.

The patent at issue is US Patent 11,081,503. A search for this patent reveals that it is titled "Cooling of weapons with graphite foam" and describes an apparatus for passively cooling a firearm barrel using a graphite foam shell. This technical area, related to firearms, appears to be an unusual subject matter for a dispute between two major display manufacturers. This suggests either a highly unconventional application of the patent or a potential discrepancy in the provided patent number for this specific case context. Further information would be needed to clarify the relevance of this patent to the display technology companies. The accused products or technology, if related to display manufacturing, would logically diverge significantly from the literal interpretation of the patent's subject matter.

The case is proceeding in the United States District Court for the Eastern District of Texas. While the specific division and assigned judge are not immediately available in general search results for this case number, the Eastern District of Texas has historically been a significant venue for patent litigation. It is known for its perceived plaintiff-friendly rules and a judiciary experienced in patent cases, which often leads to quicker trials compared to other districts. This court's active patent docket, which saw it as the top patent district for overall litigation in Q1 2026, often makes it a strategic choice for patent assertions. The notability of this specific case would stem from the competitive nature of the parties involved in the global display market, particularly if the allegations indeed pertain to core display technologies despite the patent's seemingly unrelated subject matter.

Based on the authoritative case metadata provided and current web search capabilities, pinpointing detailed developments for "2:25-cv-00430" in the Texas Eastern District Court, specifically identified as a patent infringement case concerning US patent 11081503, presents challenges. Many search results for the case number "2:25-cv-00430" point to unrelated cases in various other district courts (e.g., Maine, Maryland, Oregon, Southern District of Indiana, Middle District of Pennsylvania) concerning different legal matters such as immigration, social security, government actions, and foreclosure.

However, a Lex Machina listing does indicate the existence of a case numbered "2:25-cv-00430" in the Eastern District of Texas, filed on April 23, 2025, with the last docket activity recorded on August 15, 2025. This entry does not, however, specify the parties involved or confirm it as a patent infringement case related to patent 11081503. Given the explicit instruction to treat the provided metadata as authoritative, we proceed with the understanding that this is the correct case in the correct court, and concerns patent 11081503, even if specific docket details are not broadly available through public web searches.

Regarding parallel proceedings, a significant development has occurred at the Patent Trial and Appeal Board (PTAB):

• PTAB IPR Proceeding: An Inter Partes Review (IPR) proceeding, IPR2025-00430, has been identified. For this IPR, a "Judgment Granting Request for Adverse Judgment After Institution of Trial" was issued. This indicates that a request for adverse judgment was granted after the IPR trial was instituted, suggesting an unfavorable outcome for the patent owner in that proceeding. The specific patent number involved in IPR2025-00430 is not explicitly stated in the readily available snippets, nor is its direct link to the district court case 2:25-cv-00430, but the IPR number is highly suggestive of a related matter given the numerical correlation. An IPR can challenge the validity of a patent based on novelty and obviousness, offering a faster and cheaper alternative to district court litigation for validity challenges. Once instituted, a final written decision in an IPR is typically due within 12 to 18 months.

Without specific docket entries and party names for the 2:25-cv-00430 case in the Eastern District of Texas related to patent 11081503, a detailed chronological summary of filings, motions, discovery, and trial events for the district court litigation cannot be provided. The current information suggests the case was filed on April 23, 2025, and was active as of August 15, 2025. The existence of IPR2025-00430 indicates a challenge to a patent's validity, which could impact the district court litigation, potentially leading to a stay, settlement, or influencing claim construction and validity defenses.
