Patents and Retaliation
With regard to the issue of patents, Stallman again conceded that the GPL could not make them go away. "There is literally nothing that software developers can do to protect themselves against the dangers of patents, except not allow patents in their country. We have just found out that the European Union is going to make another attempt to impose software patents," he said.But what it does is make the GPL compatible with a larger subset of those. If a free software license allowed a modified version to be distributed under the GPL, then it was compatible with the GPL, he said. "We have artificially changed the GPL so that a larger range of those licenses will be compatible. The incompatibility is always unfortunate in itself, but the whole point of the GPL was to ensure that other restrictions could not be added," Stallman said. Linux vendors and distributors like Red Hat and Novell were calling for GPL 3.0 to address the issues of patents and license compatibility. Click here to read more. Asked about the fundamental basis for the previous incompatibility of some free licenses with the GPL, Stallman said that in some cases the licenses mentioned certain trademarks, had the requirement that the command to download the source code could not be removed, or contained aggressive patent retaliation clauses. The kinds of patent retaliation that the current draft of the license would allow are limited and directed only against things that are clearly wrong. Stallman said the FSF was also hoping that, in the future, some of those license drafters would decide to make their patent retaliations compatible with the GPL so that their licenses could be compatible. Asked about what he wanted to see come from the discussion process now that the first discussion draft was public, Stallman said he hoped that a lot of people would be checking it carefully to find instances where the current words would not have the right effect, so that the wording could be fixed at the draft stage. "This is just a discussion draft and is not yet a version of the GPL, and so does not apply to any programs. But we want any problems to be found before we make an official release of GPL version 3.0 and, so, we need lots of people looking for problems," he said.

The draft license also does not, in any way, change the criteria for licenses to qualify as free software licenses, he said.
