Microsoft will soon be charging manufacturers of flash memory card devices and those which use them $0.25 per unit or up to $250,000 to use the FAT filesystem. For those who are unaware the FAT file system was developed by Microsoft back in 1976 and has become the standard file system for all digital still cameras. Microsoft owns patents to the FAT File System but for many years hasn't even hinted that it may one day decide to charge for it. These new licenses appear to come into effect immediately and specifically make mention of 'compact flash memory cards' and 'portable digital still cameras'. What a great way for Microsoft to cash in on the most popular consumer products (as if they don't make enough money already).
Phil: Surely flash memory manufacturers can get around this by simply not pre-formatting cards?
FAT File System Technology and Patent License
December 3, 2003
Most operating systems store computer files by dividing the file into smaller pieces and storing those pieces in separate clusters of a hard disk, floppy disk, or flash memory card. The FAT file system allows an operating system to keep track of the location and sequence of each piece of a file, and also allows the operating system to identify which clusters are unassigned and available for new files. When a computer user wants to read a file, the FAT file system also reassembles each piece of the file into one unit for viewing.
The first FAT file system was developed by Microsoft in 1976. That system was based on the BASIC programming language and allowed programs and data to be stored on a floppy disk. Since that time, the FAT file system has been improved upon multiple times to take advantage of advances in computer technology, and to further refine and enrich the FAT file system itself.
Today, the FAT File system has become the ubiquitous format used for interchange of media between computers, and, since the advent of inexpensive, removable flash memory, also between digital devices. The FAT file system is now supported by a wide variety of operating systems running on all sizes of computers, from servers to personal digital assistants. In addition, many digital devices such as still and video cameras, audio recorders, video game systems, scanners, and printers make use of FAT file system technology.
Microsoft is offering to license its FAT file system specification and associated intellectual property. With this license, other companies have the opportunity to standardize the FAT file system implementation in their products, and to improve file system compatibility across a range of computing and consumer electronics devices.
If you are interested in obtaining a license, please contact our Intellectual Property and Licensing Group at firstname.lastname@example.org for more information.
Pricing and Licensing
Microsoft offers a commercially reasonable, nonexclusive license so that other companies can use the FAT file system in their own products. Currently, Microsoft offers two specific types of licenses:
- A license for removable solid state media manufacturers to preformat
the media, such as compact flash memory cards, to the Microsoft FAT
file system format, and to preload data onto such preformatted media
using the Microsoft FAT file system format. Pricing for this license
is US$0.25 per unit with a cap on total royalties of $250,000 per manufacturer.
- A license for manufacturers of certain consumer electronics devices. Pricing for this license is US$0.25 per unit for each of the following types of devices that use removable solid state media to store data: portable digital still cameras; portable digital video cameras; portable digital still/video cameras; portable digital audio players; portable digital video players; portable digital audio/video players; multifunction printers; electronic photo frames; electronic musical instruments; and standard televisions. Pricing for this license is US$0.25 per unit with a cap on total royalties of $250,000 per licensee. Pricing for other device types can be negotiated with Microsoft.
Microsoft's FAT file system license offers limited rights to issued and pending Microsoft patents on FAT file system technology, as well as rights to implement the Microsoft FAT file system specification. In order to ensure interoperability between the licensed media and devices and Microsoft® Windows®-based personal computers and to improve consumer experience, the license requires that licensees' FAT file system implementations in the licensed media and devices be fully compliant with certain required portions of the Microsoft FAT file system specification. To help licensees implement the FAT file system, Microsoft will also provide certain reference source code and test specifications as part of the licensing package in both licenses.
In some cases, companies may wish to negotiate broader or narrower rights than the standard Microsoft license for FAT file systems. In this case, pricing may vary. Microsoft remains flexible to adjust terms to reflect crosslicensing, unit volume, version limitation, geographic scope, and other considerations.

Canon's mirrorless EOS R5 comes with a ton of features and capability stemming from its design inside and out. Come along with us on a guided tour of Canon's new high-end, high-megapixel camera and check it out for yourself.
Announced alongside the EOS R5, the R6 offers a lot of the same technology but in a more affordable, slightly more enthusiast-focused model. Take a closer look.
Alongside the EOS R5 and R6, Canon has announced a brace of lenses, all in the short to long telephoto range. Filling out the 'long' end are one L-series zoom, and two innovative primes.
Alongside a trio of telephoto lenses, Canon also announced a new 85mm this week. The RF 85mm F2 Macro IS STM is a compact, affordable alternative to the pro-oriented 85mm F1.2L.
The EOS R5 has been a long time coming – we knew it had 8K and we knew it had an AF joystick. But now that's it's here, what is it really like to use? Find out in our initial review based on hands-on time with the camera.
The R6 doesn't promise quite such headline-grabbing specs as its big brother, but it still packs a punch, whether you shoot stills, video or both.
Think you've read everything there is to know about the new Canon cameras? Chris and Jordan share eight important things you may have missed from today's Canon EOS R5 and R6 announcements.
We've been shooting around with the new Canon EOS R6. Initial impressions of image quality are positive, and out-of-camera JPEGs appear similar to that of the gold award-winning Canon EOS-1D X III. Have a look for yourself.
Canon has officially released the long-awaited EOS R5, the company's top-end full-frame mirrorless camera. Featuring a new 45MP CMOS sensor, Dual Pixel AF II system, 8K video capture and 20 fps bursts, this is the RF-mount camera we've been waiting for.
Although the Canon EOS R6 doesn't have the 45MP sensor and 8K video capture of the higher-end R5, it's still an incredibly capable camera with specs that outshine similarly priced peers.
The Canon RF 100-500mm F4.5-7.1L IS USM is the company's first super-zoom lens for RF-mount. Despite a relatively slow aperture range, it's very versatile, offering five stops of stabilization, weather-sealing and compatibility with Canon's new teleconverters.
Canon's RF 85mm F2 Macro IS STM is an inexpensive telephoto prime lens with a minimum focus distance of just 0.35m (14") and a 0.5x magnification. When attached to the new R5 and R6, it offers a whopping eight stops of shake reduction.
Canon has announced a pair of super-telephoto fixed-aperture primes. The 600mm and 800mm use diffractive optics to keep their size and weight down. They'll also be compatible with new 1.4x and 2x RF teleconverters.
Canon has announced a new small-footprint inkjet photo printer, the imageProGraf Pro-300. it will produce prints up to 13 x 19" and it goes on sale later this month for $900. A new textured photo paper will also arrive in July.
The new compression standard is set to reduce video file sizes by half to save space and speed-up transmission, paving the way for more portable 8K footage.
Sony recently confirmed plans to launch a successor to the video-centric a7S II. We don't even know the name of the camera, but Jordan already has a feature wish list for the new 'a7S III' – and it doesn't include 8K.
