Shanghai Jinko v. Abalance: Judge Corley dismissed WWB’s claims for lack of personal jurisdiction, without prejudice.
WWB Corporation was dismissed from the case for lack of personal jurisdiction, without prejudice. The court did not decide the alternative failure-to-state-a-claim argument or the merits of the patent-infringement allegations against WWB.
What happened
In Shanghai Jinko Green Energy Enterprise Management Co., Ltd. v. Abalance Corporation, the plaintiffs accused several defendants of infringing two U.S. patents involving solar-panel technology. Defendant WWB Corporation asked the court to dismiss the claims against it because WWB was not subject to the court’s authority and, alternatively, because the complaint did not state a valid claim.
The plaintiffs argued that the court had authority over WWB because WWB controlled another company and because WWB’s products entered the supply chain with an expected destination in the United States and California. The court rejected both arguments, finding that the evidence did not show enough control by WWB over the other company or enough connection between WWB and the accused products sold in the United States. The court also declined to allow jurisdiction-related discovery.
Judge Jacqueline Scott Corley granted WWB’s motion to dismiss for lack of personal jurisdiction without prejudice. The court did not decide WWB’s alternative argument that the complaint failed to state a claim, and it said the plaintiffs could seek permission to amend if later discovery revealed a basis for jurisdiction.

Background
Shanghai Jinko Green Energy Enterprise Management Co., Ltd. and other plaintiffs sued Abalance Corporation and other defendants for allegedly infringing U.S. Patent Nos. 11,581,454 and 11,824,136. The plaintiffs alleged that the defendants made, used, sold, offered to sell, or imported infringing solar panels and that the accused panels used the plaintiffs’ patented technology without authorization.
WWB Corporation moved to dismiss the first amended complaint under Federal Rule of Civil Procedure 12(b)(2) for lack of personal jurisdiction. Personal jurisdiction is a court’s authority to decide a case involving a particular defendant. WWB alternatively moved under Rule 12(b)(6) for failure to state a claim, but the court reached only the jurisdiction issue.
Personal Jurisdiction
The court analyzed whether WWB had sufficient contacts with California to satisfy due process. The plaintiffs did not claim that WWB was generally subject to jurisdiction in California. Instead, they relied on specific personal jurisdiction, which applies when the lawsuit arises from a defendant’s purposeful activities directed at the forum state.
The plaintiffs advanced two theories. First, they argued that WWB’s control over Toyo Co. Ltd. created an agency relationship allowing Toyo’s contacts to be attributed to WWB. Under California law, ordinary parent-company oversight, shared officers, shared offices, and majority ownership are not enough; the parent must exercise control beyond what is normally expected in a parent-subsidiary relationship.
The court found that WWB’s president submitted evidence stating that WWB did not control the operations or decisions of the relevant subsidiaries and did not provide engineering, design, research, development, or technical support for the accused products. The plaintiffs submitted evidence that WWB was Toyo Co. Ltd.’s controlling shareholder, that the companies shared a chief executive officer and an address, and that WWB substantially controlled corporate actions requiring shareholder approval. The court held that this evidence did not show the degree of control necessary to establish an agency relationship for jurisdictional purposes.
Second, the plaintiffs relied on a stream-of-commerce theory. Under that theory, jurisdiction may exist when a company places products into the stream of commerce expecting them to be purchased in the forum state. WWB’s president stated that WWB sold solar panels under the Maxar brand only in Japan, did not sell or advertise products in the United States, and did not solicit U.S. business. He also stated that WWB did not provide support for the VSUN or TOYO groups, did not sell products to those groups, and did not control sales of the accused VSUN solar modules. A VSUN executive similarly stated that some accused products had not been sold in the United States and that none were sold by WWB.
The plaintiffs pointed to website statements describing VSUN products as “Engineered in Japan” and describing VSUN as Japanese-invested, as well as a WWB website that referred to VSUN’s achievements using the word “we.” The court found that these statements did not establish that WWB engineered, sold, controlled, or otherwise connected itself to the accused products sold in the United States. The plaintiffs therefore failed to make the required preliminary showing that WWB purposefully availed itself of California or had minimum contacts with the state.
Jurisdictional Discovery and Disposition
The plaintiffs requested jurisdictional discovery, which is discovery directed at facts relevant to whether the court has authority over a defendant. The court declined the request because the plaintiffs offered no evidence suggesting that WWB’s or the VSUN Group’s sworn statements were false or inaccurate. The court stated that, if discovery relevant to the parties and claims later revealed a basis for jurisdiction, the plaintiffs could move for permission to amend.
Judge Jacqueline Scott Corley granted WWB’s motion to dismiss under Rule 12(b)(2) for lack of personal jurisdiction without prejudice. Because the court resolved the case against WWB on jurisdictional grounds, it did not decide WWB’s alternative Rule 12(b)(6) motion. The order disposed of Docket No. 44.
