On Petition for Writ of Mandamus to the United States District Court for the Eastern District of Texas in No. 4:23- cv-00508-ALM, Judge Amos L. Mazzant, III. ______________________

ON PETITION ______________________

Before DYK, BRYSON, and TARANTO, Circuit Judges. PER CURIAM. ORDER Aputure Imaging Industries Co., Ltd. petitions for a writ of mandamus directing the United States District Court for the Eastern District of Texas to vacate its October 16, 2023, order and deny Rotolight Limited’s motion for substituted service. Rotolight opposes. In June 2023, Rotolight filed a complaint in the East- ern District of Texas against Aputure alleging patent in- fringement. In September 2023, Rotolight moved for substituted service pursuant to Texas Rule of Civil Case: 24-103 Document: 12 Page: 2 Filed: 01/26/2024

2 IN RE: APUTURE IMAGING INDUSTRIES CO., LTD.

Procedure 106(b), which provides for court-authorized ser- vice in any “manner, including electronically . . . that . . . evidence shows will be reasonably effective” if service via registered or certified mail or delivery “has not been suc- cessful.” * Specifically, Rotolight sought permission to serve Aputure, which is based in China, by emailing a copy of the summons and complaint to Aputure’s legal counsel. In its motion and supporting affidavit, Rotolight stated that it made several unsuccessful attempts to serve Apu- ture at a California address obtained from multiple online business databases that had the same zip code as an office listed on Aputure’s own website. In its opposition, Aputure argued that Rotolight had not shown that the California address “is actually the address of Aputure,” and asserted that Rotolight should be required to provide service that comports with the Hague Convention on the Service Abroad of Judicial and Extrajudicial Documents in Civil and Commercial Matters. On October 16, 2023, the court issued an order permit- ting substituted service on Aputure’s attorney. The court found that “service has been attempted unsuccessfully for a sufficient number of times upon Defendant at locations reported to be” its “places of residence” in California, Appx1. And the court found that delivering a copy of the complaint and summons on the specified email address “will be effective to give notice to Defendant of this suit and an opportunity to answer and defend.” Id. Aputure then filed this petition seeking to vacate that order and deny the request for substituted service. We have jurisdiction under 28 U.S.C. §§ 1651 and 1295.

* Under Federal Rule Civil Procedure 4(e)(1), service may be performed by “following state law for serving a summons in an action brought in courts of general jurisdic- tion in the state where the district court is located.” Case: 24-103 Document: 12 Page: 3 Filed: 01/26/2024

IN RE: APUTURE IMAGING INDUSTRIES CO., LTD. 3

To obtain an extraordinary writ of mandamus, a peti- tioner must satisfy three conditions: (1) the petitioner must have “no other adequate means to attain the relief [it] de- sires,” (2) the petitioner must show that the “right to issu- ance of the writ is clear and indisputable,” and (3) the court “in the exercise of its discretion, must be satisfied that the writ is appropriate under the circumstances.” Cheney v. U.S. Dist. Ct. for D.C., 542 U.S. 367, 380–81 (2004) (inter- nal quotation marks and citations omitted). Aputure has not met that demanding standard. As an initial matter, Aputure has not shown that a post-judgment appeal would be inadequate to address the alleged violation. See In re Realtek Semiconductor Corp., No. 2023-132, 2023 WL 5274627, at *1 (Fed. Cir. Aug. 16, 2023). Nor has Aputure demonstrated a clear and indisputa- ble right to relief. Aputure argues that the district court indisputably erred in refusing to require Rotolight to first attempt service of process in China in compliance with Fed- eral Rule of Civil Procedure 4(h)(2) and 4(f)(2). But that argument faces several obstacles. First, those provisions govern only service “at a place not within any judicial dis- trict of the United States,” and the district court appears to have concluded Aputure could be served in California. Sec- ond, even putting aside that finding, Rule 4(f)(2) does not displace Rule 4(f)(3), which permits service by “other court- ordered means not prohibited by international agreement.” See Nuance Commc'ns, Inc. v. Abbyy Software House, 626 F.3d 1222, 1239 (Fed. Cir. 2010) (holding that Rule 4(f)(3) “stands independently” and “on equal footing” with Rule 4(f)(2) (internal quotation marks and citation omitted)); In re OnePlus Tech. (Shenzhen) Co., No. 2021-165, 2021 WL 4130643, at *3 (Fed. Cir. Sept. 10, 2021) (noting that a showing that the plaintiff has reasonably attempted to ef- fectuate service by conventional means is not an exhaus- tion requirement for service under Rule 4(f)(3)). And finally, district courts are generally accorded broad discre- tion in determining whether to allow alternative means of Case: 24-103 Document: 12 Page: 4 Filed: 01/26/2024

service. See Nuance, 626 F.3d at 1239–41. On this record, we are not prepared to say that granting Rotolight’s motion was a clear abuse of discretion that would warrant manda- mus relief. Accordingly, IT IS ORDERED THAT: The petition is denied.
