Licenses apply to implementations and patents apply to inventions/ideas. |

A software license can allow you to theoretically use an implementation |
11 |
while a patent says no you can't without licensing that right separately. |

The reverse is equally possible; an expired patent means that using the |
14 |
invention/idea is not restricted by the patent anymore, but there may |
15 |
still be no free/open source implementation (yet). |

AIUI USE=-bindist is all three variants (swlicense_says_no || patent_says_no) |
19 |
while USE=bindist promises that (swlicense_says_yes && patent_says_yes) |
20 |
is guaranteed to be true at the cost of functionality? |
