Fwd: Bug#837666: udunits: license change

[Alastair McKinstry <mckinstry@debian.org>]

Hi,

As indicated below, the license on a package I maintain has changed, adding a new clause to the 3-clause BSD license.

Can debian-legal please review and comment on the clause:

   4) This license shall terminate automatically and you may no longer exercise
      any of the rights granted to you by this license as of the date you
      commence an action, including a cross-claim or counterclaim, against
      the copyright holder or any contributor alleging that this software
      infringes a patent. This termination provision shall not apply for an
      action alleging patent infringement by combinations of this software with
      other software or hardware.

Thanks
Alastair McKinstry

Source: udunits
Severity: normal

Dear Maintainer,

on packaging a different, new package that uses excerpts from udunits,
I noticed that the copyright information in debian/copyright does not
agree with that in (upstream) COPYRIGHT.
This seems to go back to upstream commit

https://github.com/Unidata/UDUNITS-2/commit/b362869285b629fa52b3fc464c58d74b9d6e362b

The new license is very close to a 3-clause bsd license, but adds a
fourth clause; therefore discussion on debian-legal might be indicated.

Regards,
 Klaus Zimmermann
