An anonymous reader writes "In an addendum to the recent noises by Microsoft about Linux, InformationWeek blogger Alexander Wolfe has turned up an interesting list of who owns U.S. trademarks on the word "Linux." Yes, Linus Torvalds does indeed have the trademark as far as software is concerned. But Swiss company Rosch owns "Linux" for use with laundry detergents. Interestingly, both Pogo Linux and United Linux have abandoned their trademarks (Wolfe speculates that's because of Linus's lawyers). But Finite State Machines of New Mexico owns RTLinux and Linux Networx Inc. owns "Linux Supercomputing." You can also read the full list of all 204 Linux trademarks"
