X Gets Backup In Fed. Circ. Fight Against $175M Patent Loss
Law360, Adam Lidgett, March 30, 2026
Patent quality advocacy group Askeladden LLC has backed X Corp.'s Federal Circuit challenge to a loss of more than $175 million that it saw in a patent infringement suit, saying the patented claims at issue should have been found invalid to begin with. In an amicus brief, Askeladden — a subsidiary of Clearing House Payments Co., which is run by the major banks — threw its support behind Elon Musk's X precursor, Twitter Inc., stating the patents should be found invalid under the test established by the U.S. Supreme Court in the 2014 case Alice Corp. v. CLS Bank International . That standard directs courts to ask whether the claims are directed to a patent-ineligible concept, like a law of nature, and says that if so, a court must then ask whether the claims have an inventive concept.
