OnPoint patent damages expert witness, Dr. Gareth Macartney, testified as Amazon’s damages expert in TrackTime v. Amazon at a jury trial held in September, 2023 in the U.S. District Court for the District of Delaware. The case involved allegations that Amazon and its subsidiary Audible, incorporated technology patented by TrackTime’s founder Curt Evans into its products and services. TrackTime alleged that Amazon Music’s X-Ray Lyrics feature, which displays synchronized music lyrics while a song plays, as well as Audible’s Immersion Reading “page turn” feature, which allows readers to manually turn the page in an eBook while simultaneously listening to the synchronized audiobook, infringe U.S. Patent No. 8,856,638 B2, “Methods and System for Remote Control for Multimedia Syncing,” assigned to TrackTime. Dr. Macartney provided testimony on damages under an assumption of patent validity and infringement. Following a five-day trial, the eight-person jury found for Amazon in concluding that Amazon did not infringe TrackTime’s patent, which the jury found to be invalid.
