Muvox v. Netaktion: Judge Koeltl stayed the patent case while the USPTO reexamines the patent, finding the stay could simplify litigation without undue prejudice.
Muvox LLC and Netaktion LLC; the patent-infringement action is paused while the USPTO reexamines U.S. Patent No. 11,899,713.
What happened
Muvox LLC sued Netaktion LLC for allegedly infringing a patent covering a system for categorizing streamed music and creating personalized playlists. A third party asked the U.S. Patent and Trademark Office (USPTO) to reexamine the patent, and the USPTO granted that request.
Netaktion asked the court to pause the lawsuit until the USPTO finishes its review. Muvox opposed the request, arguing that a stay would substantially delay the case and make it harder to enforce its patent rights.
Judge John G. Koeltl granted Netaktion’s motion to stay. He concluded that the reexamination could eliminate or narrow the lawsuit, the case was still at an early stage, and Muvox would not suffer undue prejudice from the temporary stay. The parties must submit a status report within 14 days after the reexamination ends.

Background
Muvox LLC brought a patent-infringement action against Netaktion LLC concerning U.S. Patent No. 11,899,713, which covers a system for categorizing music. The complaint alleges that Netaktion’s technology infringes one or more claims of the patent.
On February 11, 2025, Unified Patents, LLC, a non-party, requested an ex parte reexamination of the patent. The USPTO granted the request, and the reexamination challenges the validity of all claims of the patent.
When Netaktion moved to stay the case, it had not filed an answer. Discovery had not begun, and the court had not held a Rule 16 conference or issued a scheduling order. There had been no substantive motions or proceedings. Muvox opposed the stay, principally arguing that it would significantly delay the case and hinder enforcement of its patent rights.
Legal standard
The court explained that district courts have inherent authority to pause proceedings to promote judicial economy and efficient case management. Courts considering a stay pending patent reexamination generally examine three factors: whether the reexamination will simplify the issues and trial, how far the case has progressed, and whether the stay will prejudice the party opposing it.
Court’s analysis
The court found that the USPTO proceeding could substantially simplify the case or eliminate the need for it. The reexamination covers the core patent claims asserted in the lawsuit. If claims are amended or canceled, the scope of the litigation could be reduced or the case could become moot. Even if the patent remains valid, the reexamination record could assist with interpreting the patent claims and resolving other issues.
The court also found that the case’s early stage strongly supported a stay. Netaktion had not answered, no trial date had been set, and continuing the case during the reexamination could lead to duplicative work, wasted resources, or inconsistent outcomes.
Finally, the court concluded that Muvox would not suffer undue prejudice. Netaktion requested the stay before answering and within three months after the case began. The USPTO had already granted the reexamination request, and the record contained no evidence that Netaktion was seeking an unfair tactical advantage. The court also found nothing showing that the parties were direct competitors, which weighed against finding competitive prejudice.
Disposition
Judge John G. Koeltl granted Netaktion’s motion to stay. The action is stayed pending the conclusion of the USPTO’s ex parte reexamination of the patent. The parties must provide a status report within 14 days after the reexamination proceeding concludes.
