Enovsys LLC v. Uber Technologies, Inc.

Background

Enovsys alleged that Uber infringed claims of three patents: U.S. Patent Nos. 6,441,752, 6,756,918, and 7,199,726. Enovsys’s complaint referred broadly to infringement of “one or more claims” and identified at least certain claims of each patent.

Uber moved to dismiss. On June 17, 2024, the court dismissed the complaint without leave to amend, holding that the asserted patents were ineligible for patent protection under 35 U.S.C. § 101. Enovsys later sought reconsideration and clarification regarding which claims the dismissal covered. The court had previously denied part of Enovsys’s first reconsideration motion but deferred resolving the scope of the dismissal.

Scope of the Earlier Dismissal

The parties treated the scope question as jurisdictional. In patent cases, whether a case or controversy exists must be assessed claim by claim. Enovsys argued that its February 8, 2024 infringement contentions narrowed the claims at issue to specified claims of the three patents.

The court rejected that argument. The contentions omitted some claims originally identified in the complaint but added other claims that the complaint had not specifically identified. Enovsys also declined to agree that it had withdrawn all claims other than those listed in the contentions. The court therefore found that the contentions did not clearly narrow or clarify which claims remained at issue.

The court concluded that Enovsys’s open-ended complaint left open the possibility that it could assert any claims of the three patents. Uber’s motion to dismiss challenged all claims, and the court had jurisdiction over all claims when it entered the earlier dismissal. The court therefore ruled that the earlier dismissal applied to all claims of the asserted patents.

Second Motion for Reconsideration

Enovsys sought permission to file a second motion for reconsideration based on the Patent Trial and Appeal Board’s November 22, 2024 decisions declining to institute inter partes review of the patents. Enovsys argued that those decisions showed that claim 15 of the ’918 patent was not representative of all the claims and that the patents contained technical improvements over prior technology.

The court disagreed. It found that claim 15 of the ’918 patent covered both categories identified by Enovsys: claims involving tracking proximity between mobile units and claims involving geographic boundaries and location information. The court therefore maintained its earlier conclusion that claim 15 was substantially similar to, and linked to the same abstract idea as, the other claims.

The court also held that the Patent Trial and Appeal Board’s findings about nonobviousness did not undermine its separate patent-eligibility analysis. The court continued to find that the claims were directed to abstract ideas involving the collection and analysis of location or proximity information, and that they used generic telecommunications components rather than a specific improvement in computing or telecommunications technology.

Disposition

The court found that the earlier motion-to-dismiss order applied to all claims of the three asserted patents and DENIED Enovsys’s Second Motion for Reconsideration. The opinion does not state a separate disposition of the remaining scope-related portion of Enovsys’s First Motion for Reconsideration in its conclusion.
