Liam Cromar writes "Philippe Gildas, a French television presenter is suing Microsoft for 'violation of intellectual property' — in particular the use of the 'Vista' trademark. It appears that Gildas registered the trademark two years prior to Microsoft's application, planning to use the trademark for a new television channel, Télé Vista, which was to be launched later this year. Apparently, Gildas believes that Microsoft's 'hogging of the limelight' presents an 'obstacle to the launch'. Gildas has not, however, registered the Vista trademark in categories of activity 9 and 42, which cover software. With this in mind, his case might be hard to prove."
