anti-swpat campaigner seeks pantone patent details

Hi all,

I'm working for FSFE on preventing software patentability in the EU.

The lack of Pantone support in GIMP is a useful example of how software users are harmed by software patents, but to make this claim I need to be able to point out which patents cause this problem.

Can someone tell me the patent number(s) (USA and/or EU and/or any other) that prevent GIMP from implementing pantone? I've done web searches, including searching the archives of this list, but haven't found anything solid.

If no-one minds, I'll submit the information here too: http://www.gnu.org/patent-examp/patent-examples.html#GIMP

I've searched for patents about Pantone, but there are many and it's not clear which ones cover what.

Any other solid info about patent problems in GIMP would also be appreciated. On- or off-list.

Thanks.

Is that really a patent issue? Pantone support need be nothing more complicated than a name -> colour lookup table. (That's how InDesign implements it - an EPS file defining a shedload of CMYKCustomColors).

I would have thought that the issue with Pantone colours would be Trademark and/or Copyright.

Probably best to keep this off-list; Free Software developers are better off keeping themselves entirely ignorant of patent issues, because the penalties for knowingly infringing a patent are generally much harsher than for doing so accidentally.

Publishing any examples you may find could, unfortunately, backfire for the same reason.

All the best, --

Pantone owns the copyright of the "Pantone*" terms and the color names. Googling for "pantone copyright" truns up at least one case where this was used to get a pantone palette off the web.

Does anyone update this site? Right now, it reads like the LZW patent is still being claimed. I thought this went away last year?

Especially if the page is not kept up-to-date - we don't need another source to spread FUD, the holders of trivial patents can dothis on their own.

HTH, Michael
