US Patent 6,266,674 Subject of Widespread Litigation Campaign, Ultimately Declared Invalid

US Patent No. 6,266,674, titled "Random access information retrieval utilizing user-defined labels," has been at the center of a prolific litigation campaign initiated by the non-practicing entity (NPE) eDekka LLC. This campaign, which began in 2013, targeted a vast number of online retailers, alleging that their website's "shopping cart" functionality infringed upon the patent. The overwhelming majority of these lawsuits were filed in the U.S. District Court for the Eastern District of Texas.

The litigation campaign ultimately concluded with the patent being declared invalid. In a pivotal ruling, Judge Rodney Gilstrap of the Eastern District of Texas found the patent to be invalid under 35 U.S.C. § 101, which pertains to patentable subject matter. This decision had a cascading effect, leading to the dismissal of all pending cases in the consolidated litigation.

Below is a summary of the known litigation involving US patent 6,266,674:
