rizzo320 writes "AppleInsider is reporting that an Illinois-based company and its Nevada partner have filed a lawsuit against Apple Inc., alleging that Mac OS X 10.4 'Tiger' infringes an interface patent relating to the OS's nearly universal use of tabs. The suit was filed in the patent troll's and forum shopper's favorite venue: Marshall, TX. The patent in question is 5072412, which was originally issued to Xerox in 1987, but is now owned or licensed to IP Innovation LLC and its parent Technology Licensing Corporation. 'Category dividers triggered by Spotlight searches, as well as page tabs in the Safari web browser, bear the closest similarity to the now 20-year-old description' of the patent, according to the article. IP Innovation is requesting damages in excess of $20 million and an injunction against future sales and distribution of Mac OS X 10.4. Software patent reform can't come soon enough!"
