S3TC patent situation #15

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Hello Simon Brown (and others),

I have written several DXTn texture conversion patches for the Wine project 
(http://www.winehq.org/), however, the project's maintainer will not merge my 
patches into HEAD because of patent fears. 
Currently the patent to DXT (de)compression is held by VIA (and its satellite 
brand S3 Inc.). Someone pointed me to libsquish, an open source project 
implementing DXT algorithms.
My question is this: did VIA or S3 indemnify you or did they provide a waiver 
stating they will not sue you for implementing a DXT (de)compression algorithm? 
If so, could you advise me on how to procure such indemnification for the Wine 
project? If not, did you find a way to break the patent?

Thanks in advance,

Itzamna

Sorry for the long delay, I have rather neglected this project for a while.

The purpose of squish is to provide graphics developers with a compressor so 
that they may create texture data for GPUs that license DXT/S3TC decompression. 
 Decompression code exists only as necessary component of the code for 
compression.

As stated in MIT license that squish is provided under, the library does not 
come with any warranty.
