“In its lawsuits against the three leading Android device makers, Apple asserts a variety of patents ranging from mid-1990s Macintosh patents (such as the two HTC was found, on a preliminary basis, to infringe) to more recent technologies,” Florian Mueller reports. “Apple’s number one priority clearly is to ensure that consumers will perceive the iPhone and iPad user experience as unique. That, in turn, means that Apple shoots for a substantial degradation of the Android user experience.”
“One patent stands out because Apple appears to be extremely convinced of its validity and enforceability,” Mueller reports. “U.S. Patent No. 7,469,381 on ‘list scrolling and document translation, scaling, and rotation on a touch-screen display.'”
Mueller reports, “I found two YouTube videos (out of presumably many) of demos of mobile devices that happen to show what list scrolling on a touch screen is like with and without the invention claimed by the ‘381 patent.”
