SAN JOSE, Calif. — Old PC-era products invalidate Apple's iPhone patents, Samsung experts claimed in testimony here Tuesday. Samsung cited Borland's Sidekick and WAIS servers as examples of prior art in its defense against two of Apple's five patent infringement claims.
A Samsung expert witness said the Sidekick, a DOS-based personal organizer launched in 1984, used similar techniques as Apple's '647 patent on quick links. He also cited the 1991 EmbeddedButtons research project at Xerox PARC as prior art invalidating the patent.
Apple's patent describes ways to detect telephone numbers, for example, and to call up relevant apps automatically, such as a phone dialer. Court demonstrations showed the Sidekick and EmbeddedButtons performing roughly similar tasks, though in the vintage world of DOS-era text interfaces.
Borland's Sidekick, introduced in 1984, did things Apple patented for the 2007 iPhone, Samsung claimed.
Even if the patents are valid, Samsung phones and Google code don't infringe on them, said Kevin Jeffay, chairman of the computer science department at the University of North Carolina at Chapel Hill and a Samsung expert witness. The smartphone code uses different techniques from what Apple's patent describes, he said.
"Detecting and linking has to be done in a particular way with an analyzer server, and in my analysis, there is no analyzer server or actions processor" in the Samsung phones, Jeffay said. The simplest workaround for the patent is not using the pop-up window it describes for offering users options.
