• Jurisdiction: U.S. District Court for the Northern District of California
• Plaintiff(s): Applied Optoelectronics Inc.
• Defendant(s): Eoptolink Technology USA Inc.
• Filing Date: November 19, 2024. (Note: One source also indicates a "Complaint Filing Date" of March 7, 2025, possibly referring to a first amended complaint.)
• Current Status: The case was stayed until June 5, 2026, by an order entered on January 13, 2026. The operative pleading is a First Amended Complaint.

3. District Court Case (Northern District of California):

• Case Number: 3:24-cv-08165
• Jurisdiction: U.S. District Court for the Northern District of California
• Plaintiff(s): Applied Optoelectronics, Inc.
• Defendant(s): Eoptolink Technology USA Inc.
• Filing Date: November 19, 2024.
• Current Status: This appears to be the same case as 5:24-cv-08165-NW, with different case numbering variations provided by search results. For instance, Unified Patents lists "3:24-cv-08165" and "5:24-CV-08165" in close proximity, and some sources explicitly link 3:24-cv-08165 to the Northern District of California and the same parties. Given the information, it is highly likely these are references to the same underlying case. The status is a stay until June 5, 2026, with Applied Optoelectronics Inc. alleging infringement of multiple patents, including US10714890.

Note on Case Numbers 5:24-cv-08165 and 3:24-cv-08165: The search results indicate that these likely refer to the same case. The Northern District of California often uses different divisions (San Jose (5), San Francisco (3), Oakland (4)), and sometimes the internal case number reference might vary slightly across different reporting systems or initial filings versus subsequent amendments. The parties, filing dates, and patent in suit consistently align for both numbers, pointing to a single litigation event. The case 5:24-cv-08165-NW has a judge suffix "-NW" for Judge Noël Wise, further supporting it as the primary identifier.
