Twitter, Inc. v. Voip-Pal.com, Inc.

Background

Twitter sought a declaratory judgment—a court ruling clarifying the parties’ legal rights—that its products do not infringe VoIP-Pal.com’s U.S. Patent No. 9,935,872, titled “Producing Routing Messages for Voice Over IP Communications.” VoIP-Pal.com moved to dismiss under Federal Rules of Civil Procedure 12(b)(1), 12(b)(2), and 12(b)(3), arguing that the court lacked subject-matter jurisdiction, lacked personal jurisdiction over VoIP-Pal.com, and was an improper venue.

The ’872 patent was part of a family of eight related patents with the same title, identical figures, nearly identical specifications, and similar claims. VoIP-Pal.com had previously asserted related patents against Twitter and other telecommunications and internet companies. Several of those cases had been transferred to and litigated in the Northern District of California, where the court had made substantive rulings concerning related patents.

Subject-Matter Jurisdiction

The court held that Twitter plausibly showed an “actual controversy,” meaning a live and sufficiently concrete dispute required for declaratory-judgment jurisdiction. VoIP-Pal.com had previously sued Twitter over the related ’815 and ’005 patents, involving the same Twitter products at issue in this case. The court treated the ’872 patent’s relationship to those patents, the prior litigation, VoIP-Pal.com’s continued enforcement of related patents against other companies, and VoIP-Pal.com’s press release about continuing its intellectual-property enforcement efforts as circumstances supporting a substantial risk of future enforcement against Twitter.

The court rejected VoIP-Pal.com’s argument that the earlier litigation was too old. It explained that the prior case did not end until May 2020, when the Federal Circuit denied VoIP-Pal.com’s rehearing petition, and that precedent recognized the relevance of prior litigation involving related patents. The court also rejected reliance on a Federal Circuit case in which the patent owner had expressly stated that it had no basis to sue and had offered a promise not to sue. VoIP-Pal.com had neither stated that Twitter did not infringe the ’872 patent nor offered Twitter such a promise.

Personal Jurisdiction

The court held that it had specific personal jurisdiction over VoIP-Pal.com. Specific personal jurisdiction applies when the lawsuit arises out of or relates to the defendant’s contacts with the forum. The court found that VoIP-Pal.com purposefully directed patent-enforcement activities toward California by litigating related patent cases in the Northern District of California, including cases transferred there voluntarily from Nevada. The court also considered allegations that VoIP-Pal.com retained a law firm located in Mountain View, California and that its representative met with Apple representatives in the district concerning VoIP-Pal.com’s patent-enforcement campaign. The court said those two contacts were not enough by themselves but supported the conclusion based on VoIP-Pal.com’s litigation in the district.

The court further found that Twitter’s declaratory-judgment claim arose from those enforcement activities because the prior action against Twitter in that court was a principal basis for Twitter’s claim. It also concluded that exercising jurisdiction was reasonable and fair. The court cited VoIP-Pal.com’s prior litigation in the district, California’s interest in protecting its resident from unwarranted patent-infringement claims, Twitter’s interest in obtaining relief in California, the efficiency gained from the court’s familiarity with related patent cases, and the absence of a conflict among state interests.

Venue

The court held that venue was proper. Under the general federal venue statute, a corporate defendant resides in any district where it is subject to personal jurisdiction for the action. Because the court found that it had personal jurisdiction over VoIP-Pal.com, it concluded that venue was proper in the Northern District of California.

Disposition

Judge Lucy H. Koh denied VoIP-Pal.com’s motion to dismiss Twitter’s complaint. The order addressed jurisdiction and venue only; it did not decide whether Twitter infringed the ’872 patent or whether the patent was valid.
