Litigation summary

I have reviewed the provided patent text and executed searches for litigation involving US patent 11621360.

Here is a list of known litigation involving US patent 11621360:

1. District Court Litigation: W&Wsens Devices Inc. v. [[[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.)

   • Plaintiff(s): W&Wsens Devices Inc.
   • Defendant(s): Samsung Electronics Co., Ltd., Samsung Electronics America, Inc., Samsung Semiconductor, Inc., and Samsung Austin Semiconductor LLC
   • Jurisdiction: United States District Court for the Eastern District of Texas, Marshall Division
   • Case Number: 2:24-cv-00854-JRG
   • Filing Date: The Second Amended Complaint for Patent Infringement was filed on April 16, 2025. The initial filing date for the case is indicated as 2024 by the case number, though the specific date for the initial complaint is not in the search results provided.
   • Current Status/Outcome:
     • On November 3, 2025, the Defendants' motion to stay pending Inter Partes Review (IPR) and Post Grant Review (PGR) for the asserted patents (including US11621360) was denied without prejudice to refiling after the PTAB's institution decisions. The PTAB had not yet instituted review for any of the asserted patents at that time.
     • On November 25, 2025, Samsung's Renewed Motion to Transfer the case to the United States District Court for the Northern District of California was denied.
     • On February 23, 2026, the Court granted Samsung leave to amend its Invalidity Contentions to include evidence supporting an alleged priority date of November 22, 2021, for the asserted patents, which could potentially render them invalid.

2. PTAB Litigation: IPR2025-00994

   • Plaintiff(s) (Petitioner): Samsung Semiconductor Inc., Samsung Austin Semiconductor LLC, Samsung Electronics Co Ltd, Samsung Electronics America Inc.
   • Defendant(s) (Patent Owner): W&W Sens Devices Inc.
   • Jurisdiction: Patent Trial and Appeal Board (PTAB)
   • Case Number: IPR2025-00994
   • Filing Date: June 20, 2025
   • Current Status/Outcome: Not Instituted - Procedural

It's important to note that the PTAB case IPR2025-00994 for US11621360 was "Not Instituted - Procedural". This means the PTAB did not proceed with an inter partes review on procedural grounds. The District Court in Texas Eastern District, in case 2:24-cv-00854-JRG, had previously denied a motion to stay pending IPR/PGR because the PTAB had not yet instituted review.
