Subject RE: Error in Apache 2.0 License
Date Thu, 09 Apr 2015 23:52:11 GMT
In fact, Apache 2.0 includes an express patent license to use, as there is to all the enumerated
patent rights under 35 USC 271(a):

3. Grant of Patent License. Subject to the terms and conditions of this License, each Contributor
hereby grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made, *use,* offer to sell,
sell, import, and otherwise transfer the Work, where such license applies only to those patent
claims licensable by such Contributor that are necessarily infringed by their Contribution(s)
alone or by combination of their Contribution(s) with the Work to which such Contribution(s)
was submitted. If You institute patent litigation against any entity (including a cross-claim
or counterclaim in a lawsuit) alleging that the Work or a Contribution incorporated within
the Work constitutes direct or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate as of the date such litigation
is filed.

I am typically quite hesitant to contradict Greg on anything, but there is a patent grant
section in the Apache license.

What Greg says is literally correct however, in that the Apache Software License as an agreement
between Apache Software Foundation and the user only grants a copyright.

But section 3 notifies the user that there is a patent grant from all of the contributors
to Apache software.  This is one of the most important aspects of the Apache license.  As
Madeleine correctly intimated and Greg amplified you need both a right to copy and a right
to use to have open software.  The Apache license grants the right to copy and tells you about
the right to use that you already have received by virtue of contributors contributing software
under their contributor agreement.

So the Apache licensing scheme does cover both  right to copy and right to use.

Madeleine: the Apache License is a *copyright* license. That only deals with making copies,
derivations, and several other rights, under US copyright law[1]. These laws do not impinge
on your *use* of the software, once you've obtained a copy of the software under the provided

*Use* of the software can only be limited via contract law. (though I can imagine a scenario
where people attempt to limit use under the "public performance" and "public display" rights
given by copyright law; I believe the AGPL is trying this, but the Apache License certainly
does not)

I have redirected your query to the legal-discuss@apache.org<mailto:legal-discuss@apache.org>
mailing list. The people here can correct my first-response, and provide answers to any further
questions you may have.

I noticed when reading the Apache 2.0 License Agreement that in Section 2 it read:

"2. Grant of Copyright License. Subject to the terms and conditions of this License, each
Contributor hereby grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
irrevocable copyright license to reproduce, prepare Derivative Works of, publicly display,
publicly perform, sublicense, and distribute the Work and such Derivative Works in Source
or Object form."

I noticed that unlike Section 3 (which gives permissions to use the patented parts of the
software), Section 2 gives the permissions for just about everything but the actual use of
the software under the copyright license grant. This could cause trouble for the actual end
user of the software.

Could someone please fix this mistake?

Here is the link to the License:
