On August 29, Multimedia Patent Trust (“MPT”) filed a patent infringement lawsuit against Apple in the U.S. District Court for the Southern District of California. The patent at issue is U.S. Patent No. 5,500,678, entitled “Optimized Scanning of Transform Coefficients in Video Coding.” In essence, the patent describes a method of digital video compression.
The complaint first alleges that several of Apple’s products, including the iPhone 4S, iPad 2, and the “new iPad” encode video in a way that infringes on MPT’s ‘678 patent. Second, MPT alleges that a handful of Apple software uses the patented methodology “by virtue of the manner in which they encode video.” The third allegation of infringement focuses on the Apple computers as a whole, naming the virtually all current and recent lines of the company’s computers, including the Mac Mini, Mac Pro, MacBook, MacBook Pro, and MacBook Air.
