Copyrights protect expressions of ideas. Patents protect "ideas". I guess, it's reasonable to expect that copyrights will end up "protecting" things forever -- law makers constantly extend the "deadline". The protection period for patents is rather limited (vs copyrights). Patent rights are "negative" -- the patent owner can "exclude others". The patent owner himself may not be able to practice the invention if it's subject to other patents needed to practice the invention. <quote> Sometimes one patent blocks practicing (making or using) a second patent, while that second patent blocks practicing the first patent. In that case, neither patent owner can practice his invention until the other patent expires, and so it is likely that the two patent owners will cross-license their patents, giving each the ability to practice their patents. </quote> > > Maybe you saw nonsense in disallowing the boost developers ourselves > to issue a pantent on our own software.

You aren't really forced to "prove" anything. Committers aside, that is the problem (risk) of the Recipient. For example, the CPL states: "c) Recipient understands that although each Contributor grants the licenses to its Contributions set forth herein, no assurances are provided by any Contributor that the Program does not infringe the patent or other intellectual property rights of any other entity. Each Contributor disclaims any liability to Recipient for claims brought by any other entity based on infringement of intellectual property rights or otherwise. As a condition to exercising the rights and licenses granted hereunder, each Recipient hereby assumes sole responsibility to secure any other intellectual property rights needed, if any. For example, if a third party patent license is required to allow Recipient to distribute the Program, it is Recipient's responsibility to acquire that license before distributing the Program. d) Each Contributor represents that to its knowledge it has sufficient copyright rights in its Contribution, if any, to grant the copyright license set forth in this Agreement.
