MfA,

GPL says, in general terms:
"you can use/distribute this code as much as you like subject to conditions x, y, z"
Non of x, y, z says you must respect patent law.[/i]

For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program.

This does not say that I must respect the patent licensor. It is just pointing out to me that I have a choice:

1. don't use the code at all
2. violate GPL by buying a patent license for my product
3. violate the patent by releasing my product under GPL
4. do both 2 and 3

and that the only way to be completely legal is option 1.

Is this true?

Darn, i didn't download the latest build :(


I have exams, and don'thave time to read all the posts, but Patents expire in 17 years don't they? Maybe this piece of info could be of help.


I enjoyed the ride while it lasted,

ja.

The XviD-land engineers discovered some bubblegum on the tracks and had to stop the ride temporarily to get rid of it ... or something.
