LBT IP II LLC v. Uber Technologies, Inc.

Background

LBT sued Uber for allegedly infringing four patents: U.S. Patent Nos. 7,728,724; 7,598,855; 8,531,289; and 8,224,355. The case was initially filed in the Western District of Texas and was transferred to the Northern District of California in July 2022. Uber later filed petitions for inter partes review, an administrative patent-review process conducted by the Patent Trial and Appeal Board (PTAB), covering claims involved in the lawsuit. The PTAB instituted review proceedings, and Uber moved to stay, or pause, the district-court case until those proceedings were finally resolved. LBT opposed the motion.

Legal standard

The court considered three factors commonly used in the district: the stage of the case, whether a stay would simplify the issues, and whether the stay would unfairly prejudice or create a tactical disadvantage for the party opposing it. The decision was made without oral argument, and the scheduled hearing was vacated.

Analysis

The early stage of the case favored a stay. Discovery was incomplete, no trial date had been set, and claim construction was not yet complete; only the opening brief had been filed.

The court found that the PTAB proceedings would likely simplify the case. The PTAB could cancel claims, which could eliminate the need to decide infringement for those claims. Even if claims survived, statutory estoppel could limit Uber’s ability to raise in the lawsuit invalidity arguments that it raised or reasonably could have raised during the inter partes review. The court also found enough overlap among all four patents—including shared subject matter, similar claim limitations and elements, and the same accused products—to conclude that the review would simplify issues involving the two patents not yet subject to instituted review proceedings. The court emphasized that simplification, rather than complete elimination of the lawsuit, was the relevant inquiry.

The prejudice factor also favored a stay. Uber filed its review petitions and stay motion promptly. The court noted that LBT and Uber appeared not to be direct competitors, although they disputed the nature of their relationship. The court was not persuaded that LBT’s licensing of the patented inventions established undue prejudice, reasoning that courts generally find monetary damages an adequate remedy for infringement by a patent licensee.

Disposition

Judge William H. Orrick granted Uber’s motion to stay the case pending final resolution of the pending inter partes review proceedings. The stay applies to the entire case. The parties must notify the court within one week after the proceedings conclude or by December 14, 2023, whichever occurs first, and request that the matter be reopened and a case-management conference scheduled.
