I’m not particularly a fan of software patents. Apple have just been sued by a company called IP Innovation over their use of tabbed interfaces in Mac OS X. Yes, that’s right, over tabbed interfaces.
“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!”
The patent filing dates back from 1987 and if you take a look at it, clearly describes something which isn’t exactly considered amazingly innovative nowadays. I’m struggling to think of a single graphical application that doesn’t make use of some form of multiple ‘workspaces’ as they are referred to in the filing. IP Innovation simply bought the intellectual property rights from Xerox, who pretty much invented most of the concepts of the graphical user interface as we know it today.
