Microsoft Corp has given the most detailed description to date of the number of open-source computer programs it says infringe on its patents, but the company says it still prefers licensing deals with open-source developers, software distributors and users instead of legal action against them.
"There is no reason why any segment of the industry needs to be exempt from intellectual property rules," Horacio Gutierrez, a Microsoft vice president for intellectual property and licensing, said in an interview on May 15.
At the most basic level, open-source software is distributed free of charge to consumers or businesses to use on their computers, and to programmers to modify, build on, and distribute again also for free.
Open-source programs step on 235 Microsoft patents, the company said. Free Linux software violates 42 patents. Graphical user interfaces the way menus and windows look on the screen, breach 65. E-mail programs step on 15, and other programs touch 68 other patents, the company said.
