Litigation summary

The patent text itself provides initial leads for litigation. I've noted two specific cases: a PTAB IPR and a US District Court case.

1. PTAB Case:

• Case Number: IPR2025-01553
• Status noted in patent: Not Instituted - Procedural

2. US District Court Case:

• Jurisdiction: Texas Eastern District Court
• Case Number: 2:25-cv-00334
• Status noted in patent: "US case filed in Texas Eastern District Court"

Now I will use the search results to populate the missing details and verify the information.

From the search results:

• For case 2:25-cv-00334 (Texas Eastern District Court):
  • Plaintiff(s): PayGeo, LLC
  • Defendant(s): [[[Samsung Electronics Co.](/litigations/by-defendant/Samsung%20Electronics%20Co.), Ltd.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.) et al.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.%20et%20al.) (specifically mentioning Samsung Electronics America, Inc. and Samsung Electronics Co., Ltd.)
  • Jurisdiction: Texas Eastern District Court
  • Case Number: 2:25-cv-00334
  • Filing Date: April 1, 2025 or April 2, 2025 (There's a slight discrepancy in filing date between the snippets, with one saying April 1, 2025 and others April 2, 2025. I will list April 2, 2025 as it appears in multiple sources).
  • Outcome or Current Status: The case involves patent infringement claims. It appears to be an active case with scheduled events including a Claim Construction Hearing on October 21, 2026, and a Case Management Conference on March 15, 2027. One source indicates "Status Closed" for this case, which contradicts the upcoming event information. Given the mention of future hearing dates from multiple sources, it is more likely that the case is active or ongoing rather than closed, and the "Status Closed" might refer to a specific docket entry or an error. I will prioritize the information about future hearings as indicating an ongoing status.

I will explicitly state the conflict regarding the status. I don't have enough information from the provided snippets to determine the plaintiff/defendant for the PTAB IPR case IPR2025-01553 from the search results, only that the status is "Not Instituted - Procedural" as mentioned in the patent text itself. The searches for the IPR mostly confirm the case number but do not provide plaintiff/defendant in the snippets.
The Darts-IP link ("First worldwide family litigation filed") from the patent text requires further investigation to extract specific case details. I will mention it as a general family litigation without specific details as the snippets do not provide them.

Here's the compilation of the known litigation:

Known Litigation Involving US Patent 10937018:

   • Case Number: 2:25-cv-00334

It is currently ongoing with upcoming events, including a Claim Construction Hearing scheduled for October 21, 2026, and a Case Management Conference for March 15, 2027.

   • Jurisdiction: Patent Trial and Appeal Board (PTAB)
   • Case Number: IPR2025-01553
   • Filing Date: Not specified in the provided snippets, but the case number implies a 2025 filing.

3. Worldwide Family Litigation:

   • Outcome or Current Status: The patent family is noted as having "First worldwide family litigation filed" with a link to Darts-IP. Specific details (plaintiff, defendant, jurisdiction, case number, filing date, and outcome) for this general family litigation are not available in the provided search snippets.The user wants to know about litigation involving US patent 10937018. I have already identified two specific cases from the provided patent text and confirmed/extracted details for one of them (the district court case) using the search results. I also noted the PTAB case directly from the patent text.

Here's what I have so far:

1. US District Court Case:

   • Plaintiff(s): PayGeo, LLC
   • Defendant(s): Samsung Electronics Co., Ltd. et al. (Samsung Electronics America, Inc. and Samsung Electronics Co., Ltd.)
   • Jurisdiction: Texas Eastern District Court
   • Case Number: 2:25-cv-00334
   • Filing Date: April 2, 2025
   • Outcome or Current Status: Ongoing, patent infringement claims, with a Claim Construction Hearing on 10/21/2026 and Case Management Conference on 03/15/2027. There's a conflicting "Status Closed" in one snippet which seems incorrect given the scheduled future events.

2. PTAB Case:

   • Jurisdiction: PTAB
   • Case Number: IPR2025-01553
   • Filing Date: Not explicitly stated in the provided snippets, but the IPR number suggests 2025.
   • Outcome/Status: Not Instituted - Procedural

3. General "Family has litigation" / "First worldwide family litigation filed":

   • This is a general statement from the patent text, with a link to Darts-IP. The search results did not provide specific details (plaintiff, defendant, case number, filing date, outcome) for this broad category beyond what's already covered by the specific cases. I will mention that specific details are not readily available from the current search for this "family litigation".

I believe I have sufficient information to answer the user's request based on the provided patent text and the search results. I will structure the answer clearly, listing each known litigation and its details.Known litigation involving US patent 10937018 as of April 26, 2026, includes the following:

1. PayGeo, LLC v. Samsung Electronics Co., Ltd. et al.

   • Plaintiff(s): PayGeo, LLC
   • Defendant(s): Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc.
   • Jurisdiction: U.S. District Court for the Eastern District of Texas
   • Case Number: 2:25-cv-00334
   • Filing Date: April 2, 2025
   • Outcome or Current Status: This case involves patent infringement claims and is currently ongoing. Scheduled events include a Claim Construction Hearing on October 21, 2026, and a Case Management Conference on March 15, 2027. While one snippet indicates a "Closed" status, this appears to be contradicted by the confirmed future hearing dates, suggesting the case is active.

2. Inter Partes Review (IPR) Proceeding

   • Jurisdiction: Patent Trial and Appeal Board (PTAB)
   • Case Number: IPR2025-01553
   • Filing Date: Not explicitly stated in the provided snippets, but the case number suggests a 2025 filing.

The patent document also broadly mentions "Family has litigation" and "First worldwide family litigation filed" linking to Darts-IP; however, specific details such as plaintiff(s), defendant(s), case number, filing date, and outcome for this broader category were not detailed in the provided search results beyond the specific cases listed above.
