BackWeb files patent infringement lawsuit against Microsoft

Backweb, an Israeli company which creates communications acceleration software based on Push technology for the Web, intranets and extranets has filed a lawsuit against Microsoft claiming that the Microsoft Windows Update feature infringes on Backweb's 1999 patent titled Method and apparatus for transmitting and displaying information between a remote network and a local computer.

BackWeb alleges that Microsoft's Background Intelligent Transfer Service (BITS), Windows Update and other products infringe four U.S. patents owned by BackWeb, covering methods for transmitting information between a remote network and a local computer (U.S Patent No: 5,913,040 ) and distributed client-based data caching systems. The Microsoft products at issue are used regularly for Windows updates, IE, and Office applications. Additionally, the BITS product is used by other companies developing applications on Windows OS.
