Another day, another lawsuit. As pointed out by “AppleInsider” (, “non-practicing” entity WhitServe on Friday filed a complaint against Apple, claiming that the Mac OS X’s Quick Look function infringes on its file viewing patent from 2011.

Quick Look lets you browse files– photos, Pages documents, Keynote presentations, QuickTime movies, Microsoft Word and Excel files — without having to open an application.

In its claim, filed with the U.S. District Court for the District of Connecticut, WhitServe alleges that Quick Look violates the company’s U.S. Patent No. 7,921,139 for a “System for sequentially opening and displaying files in a directory,” which was applied for in 2006 and granted in April of 2011.
