"I agree, especially when MS fires many employees, and needs to present good financial results. They may think it's time to get their return on investment out of all these pattents (cash cows). Sueing all companies that sell devices that use MS patents would yield a fortune for MS. Imagine all MP3 players, all USB flash keys, mobile phones, memory sticks, digital video recorders, digital cameras, etc… They all use FAT32. Imagine all other patents that we don't think about. MS has hundreds of thousands of patents in their sleeves. There are billions of electronic devices around, not to mention software patents and commercial applications sold every minute…This represents a lot of money Microsoft could suck in in a period of economic downturn."
