Justin, The UDUNITS package is intended to be FOSS. Both GitHub and a license-person at the Free Software Foundation agree that it is. The anti-software-patent clause in the UDUNITS license is similar in intent to the following (from which it was adopted and adapted): Section 7 of "Common Public License Version 1.0" Section 7 of "Common Public License, version 1.0 (CPL-1.0)" Section 7 of "IBM Public License Version 1.0 (IPL-1.0)" Section 8 of "Lucent Public License Version 1.02 (LPL-1.02)" Section 7 of "Lucent Public License, Plan 9, version 1.0 (LPL-1.0)" Clause 3 of "Apache License, Version 2.0" Clause 3 of "Educational Community License, Version 2.0 (ECL-2.0)" Clause 11(c) of "RealNetworks Public Source License Version 1.0 (RPSL-1.0)" Clause 10 of "The Non-Profit Open Software License version 3.0 (NPOSL-3.0)" Clause 10 of "The Open Software License 2.1 (OSL-2.1)" Clause 10 of "The Open Software License 3.0 (OSL-3.0)" Clause 10 of "Academic Free License 3.0" Clause 13 of "Artistic License 2.0" Section 7 of "Eclipse Public License -v 1.0" Section 7 of "Eclipse Public License 1.0 (EPL-1.0)" Clause 8 of "Computer Associates Trusted Open Source License 1.1 (CATOSL-1.1)" Section 10 of "GNU AFFERO GENERAL PUBLIC LICENSE, Version 3 (AGPL-3.0)" Section 10 of "GNU General Public License, version 3 (GPL-3.0)" Clause 6(E) of "Adaptive Public License 1.0" All the above can be found at the Open Source Initiative <https://opensource.org/search/node/cross-claim>. The bug-report you referenced appears to indicate that we were asked about this before and refused to answer. I don't recall being asked about this (I'm the only developer and support person for the UDUNITS package). Please feel free to continue this interesting conversation. > Dear devs, > > Gentoo Linux  has classified your extension of the BSD license used > for udinits-2.2.20 to be non free.
