Licenses and patents

That sounded a bit like completely missing the point. While only the "GPL family of licenses" have clauses dealing with patents, all free software licenses are incompatible with software patents, in that software patents prohibit the kinds of use free software licenses want to allow (unless you get licenses to all software patents in the affected software, which quite probably is either impossible or prohibitively expensive).

And even if you get all the software patent licenses for the affected software, you will still almost always be unable to exercise some of the freedoms the free software license tries to give you, in particular the freedom to release the software, together with any improvements you made to it, so that everyone can use it. That is a freedom copyright would usually prevent, and which free software licenses explicitly try to give you back, so it is their intent that you have it again. Software patents undo that for the affected software.
