Several technology and photography websites, including Slashdot, Imaging Resource and BytePhoto, are reporting that Microsoft are going to enforce patents that it holds for the FAT file system. In effect this mean that Microsoft will charge a fee for use of a technology that was first developed way back in 1976.

The fee applies to any company that uses the FAT system, which includes manufacturers of solid state media cards and digital still and video cameras. Apparently the patents have been around for over 10 years, and only now when the use of the FAT system is widespread have Microsoft decided to enforce them and start charging a fee. There are two types of license, one for removable solid state media manufacturers (e.g. compact flash) and one for consumer electronics devices. Pricing for both licenses is US$0.25 per unit with a cap on total royalties of $250,000 per manufacturer. How generous of Microsoft to cap the total amount…

What does this mean for consumers? Well, the price of digital memory cards and cameras themselves may go up slightly. Alternatively, Imaging Resource editor Michael R. Tomkins suggests that “flash manufacturers could avoid paying the fees by simply offering their flash cards for sale unformatted - and we’d not be surprised to seem them do so, in a business where violent price wars have driven profits down to a bare minimum.” Hopefully most companies will choose to absorb this sudden new cost and not pass on any increase to the general public.
