What happened
In Robert Bosch Semiconductor LLC v. Aumos Technology, Inc., Robert Bosch renewed a request for the court to issue letters rogatory, which are formal requests for help from a foreign court or judicial authority. The court had previously denied an earlier request as incomplete.
Bosch asked the court to sign and seal its request for international judicial assistance. It provided English and Mandarin copies of the complaint and service documents and confirmed that it would pay related costs. The documents would be sent to the U.S. Department of State for transmission to Taiwan.
Judge Haywood S. Gilliam, Jr. granted both motions and directed the clerk to sign and seal the forms. Bosch must file proof that Aumos was served, or a status report about its service efforts and the additional time needed, by November 17, 2025.

Background
Robert Bosch Semiconductor LLC previously moved for issuance of letters rogatory. The court found that earlier motion deficient because it did not ask the court to take a specific action or provide a basis for that action, did not explain why certain certificates were attached, and did not include related documents for certification. The court denied that motion and allowed Bosch to renew it by August 11, 2025.
Bosch timely renewed its motion. It asked the court to sign and seal its Request for International Judicial Assistance. Bosch stated that it would transmit the signed documents to the U.S. Department of State, which would oversee their transmission to Taiwan. Bosch also confirmed that it would reimburse the court, the courts of Taiwan, and the Department of State for costs and would deposit the required check with the Department of State. It attached English and Mandarin versions of the operative complaint and the documents needed for service.
Court's reasoning
The court stated that issuing letters rogatory is discretionary. It noted that the Northern District of California had previously granted letters rogatory in cases involving Taiwanese defendants. The court found that Bosch had complied with the directions given for refiling the motion and saw no reason not to exercise its discretion to grant the request.
Ruling and next step
The court granted both motions and directed the clerk to affix the court's signature and seal to the forms. By November 17, 2025, Bosch must file a declaration and supporting proof confirming that Aumos has been served, or file a status report describing the status of its efforts to serve Aumos and how much additional time it needs. The order does not decide the merits of the underlying dispute.
