Opinion

WONDERSHARE TECHNOLOGY Case No. 25-cv-07322-JSC GROUP CO., LTD., et al., Plaintiffs, ORDER RE: MOTIONS TO DISMISS v. Re: Dkt. Nos. 38, 39 SUPERACE SOFTWARE TECHNOLOGY CO., LTD, et al., Defendants. Before the Court are Defendants’ motions to dismiss Plaintiffs’ complaint. (Dkt. Nos. 38, 39.)1 Plaintiffs and Defendants are companies who offer competing PDF software products. Plaintiffs allege various federal and California state claims for false advertising and unfair competition. Defendants move to dismiss Plaintiffs’ complaint in its entirety on the grounds of forum non conveniens, lack of personal and subject matter jurisdiction, insufficient service of process, and failure to state a claim. After carefully considering the arguments and briefing submitted, the Court concludes oral argument is unnecessary, see Civ. L.R. 7-1(b), and GRANTS Defendants’ motion, and DISMISSES Plaintiffs’ complaint in its entirety under the doctrine of forum non conveniens.2 Defendants have met their burden of showing China is an adequate forum, and the public and private factors strongly counsel in favor of dismissal. Defendants’ evidence shows China’s false advertising and unfair competition laws give Plaintiffs a potential avenue for redress. Defendants are also amenable to suit and subject to jurisdiction in China. Additionally, there is little public or 1 Record citations are to material in the Electronic Case File (“ECF”); pinpoint citations are to the ECF-generated page numbers at the top of the documents. private interest in litigating in Plaintiffs’ chosen forum because none of the parties are United States residents; Defendants’ software is used globally; Defendants have not purposely directed activities towards the U.S. market; and neither Defendant has employees, executives, offices, or assets in the United States. A. The Parties and the Complaint’s Allegations Plaintiffs Wondershare Technology Group Co. and Wondershare Technology (Hunan) Co., as well as Defendant Superace Technology Co. (“Shanghai Superace”), are companies “organized under the laws of the People’s Republic of China,” each with a principal place of business in China. (Dkt. No. 1 ¶¶ 6-8.) The other Defendant, Hongkong Superace Software Technology Co. (“Hong Kong Superace”), “is a company organized under the laws of … Hong Kong,” with a principal place of business in Hong Kong. (Id. ¶ 9.) Plaintiffs market and sell PDFelement, a software application used “to create, edit, convert, and manage PDF files.” (Id. ¶ 20.) “The software has been adopted by millions of users in more than 200 countries and regions[.]” (Id. ¶ 23.) Plaintiffs allege they have a pending trademark application for PDFelement and have “engaged in continuous commercial use of the PDFELEMENT designation in the United States, giving rise to common-law trademark rights and significant goodwill[.]” (Id. ¶ 19.) Defendants “develop[] and market[ a] competing product known as ‘UPDF,’” which has similar uses and functions to PDFelement. (Id. ¶¶ 25, 31-42.) Plaintiffs allege Defendants “have engaged in an iterative and sustained campaign of false and misleading advertising designed to promote their competing product, UPDF, at the expense of [Plaintiffs’] flagship product, PDFelement.” (Id. ¶ 31.) Specifically, Plaintiffs claim Defendants “repeatedly edited and republished over time” a page on Defendants’ website that compares the two products and misrepresents PDFelement’s capabilities, features, and performance metrics. (Id. ¶ 31-42.) Plaintiffs also allege Defendants have directed activities towards the United States and California; for example: products nationwide through online platforms and app marketplaces, including the Apple App Store and Google Play Store, which are readily accessible to consumers in this District. Their unlawful conduct, including the dissemination of false and misleading comparative charts and accompanying FAQ-style statements, has caused, and continues to cause, injury to Plaintiffs in California.

[…]

Defendants operate official accounts on Instagram, TikTok, and X (formerly Twitter), which they use to promote their products to U.S. consumers, including those located in California. In addition,

Defendants published the challenged comparative materials and narrative claims on their website (http://updf.com/), which is hosted and/or mirrored by CloudFlare Inc. in San Francisco, California, thereby tying the false advertising to infrastructure located in this District. (Id. ¶¶ 12-13.) B. Defendants’ Evidence Defendants’ evidence contextualizes and rebuts Plaintiffs’ allegations. Defendants do not dispute the parties’ citizenship or Plaintiffs’ allegations the UPDF product, website, and advertising are accessible in the United States through the internet. (See generally Dkt. Nos. 38, 39.) Defendants attest, though, they are “distinct entities” with “separate ownership” and do not control each other’s employees. (Dkt. No. 38-1 ¶ 7; Dkt. No. 39-14 ¶ 6.) Additionally, Defendants clarify UPDF is a product of Shanghai Superace, not Hong Kong Superace: the latter “did not in any way develop, operate, control, manage, or direct” the updf.com website, the website’s contents, or the UPDF application. (Dkt. No. 39-14 ¶¶ 6, 7.) Additionally, UPDF users live and work across “236 countries and regions,” with “less than 6%” of users being in the United States. (Dkt. No. 38-1 ¶ 11.) The updf.com website, too, “is available globally and in countless languages.” (Id. ¶ 12.) Defendants also explain, with hyperlinks to CloudFlare’s website, the technical process behind how CloudFlare’s servers host the updf.com website:

The website https://updf.com is not deployed in California. Shanghai Superace subscribes only to CloudFlare’s Business Plan, using only its Content Delivery Network (“CDN”) service. Shanghai Superace did not purchase any server hosting or mirroring services from CloudFlare.
