Excalibur IP, LLC

Excalibur IP, LLC is a New York-headquartered company that operates as a non-practicing entity (NPE), primarily focused on patent assertion and licensing. The company was initially a subsidiary of Altaba Inc. (formerly Yahoo, Inc.) following the sale of Yahoo's operating businesses to Verizon in 2017. In March 2020, Excalibur IP, LLC was acquired by Acacia Research. No employee count or revenue figures are publicly available.

Excalibur IP, LLC does not offer operating products or services. Instead, it manages a substantial patent portfolio, largely originating from Yahoo. This portfolio consists of over 2,000 patents, with some sources indicating nearly 4,000, focusing on technologies such as data analysis, targeted advertising, social networking, mobile advertising, online advertisement delivery, and AI modeling. Specific patent examples include social network site functionality, systems for mobile advertisement actions, and online advertisement push delivery. In February 2020, RPX Corporation announced it had secured license rights to a significant portion of Excalibur IP's patent portfolio for a syndicate of its members.

The company's patent litigation posture is that of a pure patent assertion entity, evidenced by its record of two cases as plaintiff and zero as defendant in the provided data. These cases were filed in the United States District Court for the District of Delaware, a venue frequently utilized for patent litigation.

Notable cases include Excalibur IP, LLC v. Lyft, Inc. and Excalibur IP, LLC v. Uber Technologies, Inc., both filed on July 27, 2020. The assertion of these patents is consistent with the portfolio's focus on advertising and data analysis, relevant to ride-sharing platforms. Following its acquisition by Acacia Research, subsidiaries like R2 Solutions LLC have also asserted patents from this former Yahoo portfolio in other litigation campaigns.
