I went through all the OSI-approved licenses, and all but one either
require contributors to license their patents (typically only as essential
to the implementation) or make no mention of patents. However, Clause
5 of the Frameworx license says:
Except as expressly provided herein, this License Agreement
preserves and respects Your and The Frameworx Companys respective
intellectual property rights, including, in the case of The
Frameworx Company, its copyrights and patent rights relating to
the Frameworx Code Base.
Since this is the only mention of patents, this is in effect an express
reservation of patent rights. Obviously this is not a heavily used
license, being in fact specific to one product of one licensor. But it

anything, you can put the telegram down as a forgery."
