ClaraBow writes with this excerpt from MacWorld: "A small Indiana company has sued tech heavyweights Microsoft, Apple, and Google, claiming that it holds the patent on a common file preview feature used by browsers and operating systems to show users small snapshots of the files before they are opened. ... Cygnus's owner and president Gregory Swartz developed the technology laid out in the patent while working on IT consulting projects, McAndrews said. The company is looking for 'a reasonable royalty' as well as a court injunction preventing further infringement, he said. ... Cygnus applied for its patent (#7346850) in 2001. It covers a 'System and method for iconic software environment management' and was granted by the US Patent and Trademark Office in March of this year."
