Shandong Yunxiang Century Intelligent Technology Co., Ltd. et al. v. Yannan Huang

Shandong Yunxiang v. Huang · United States District Court for the Northern District of California · November 13, 2025 · No. 25-cv-01298-JST

Summary

The United States District Court for the Northern District of California grants Defendant Yannan Huang’s motion to dismiss claims arising from an alleged patent-infringement complaint submitted to Amazon. The Court concludes that it lacks both general and specific personal jurisdiction over Huang and grants Plaintiffs leave to amend solely to add jurisdictional allegations within 21 days.

Holdings

  1. The court lacked general personal jurisdiction over Huang because he was a resident of China and Plaintiffs did not allege facts establishing the exacting contacts required for general jurisdiction in California.
  2. The court lacked specific personal jurisdiction over Huang because Plaintiffs failed to allege that Huang purposefully directed his activities at California residents or otherwise had sufficient California contacts.
  3. Plaintiffs were granted leave to amend solely to add new jurisdictional allegations, with the amended complaint due within 21 days.

Questions Presented

  1. Whether the court had general personal jurisdiction over Huang.
  2. Whether the court had specific personal jurisdiction over Huang based on his submission of intellectual-property complaints through Amazon and the alleged resulting harm.
  3. Whether dismissal should be granted for lack of personal jurisdiction and, if so, whether Plaintiffs should receive leave to amend solely to add jurisdictional allegations.

Disposition

dismissed
