      To be truly open source, code needs to be usable without requiring
      further permissions, including spending money acquiring patent
      licenses. As someone who has been a member of the board at the
      Open Source Initiative for many years, I can tell you that these
      sorts of patent clauses are considered to be a feature of
      all modern open source licenses. The patent clauses in the EPL,
      ALv2 and similar licenses have been carefully constructed, and are
      broadly accepted by industry. The ALv2 in particular is very
      popular precisely because of its patent license (which is almost
      identical to the EPL's), coupled with permissive copyright terms.

      Well, in fairness, I hear complaints from nonmembers
        about the patent clause in the EPL all the time. Our attorney at
        ORNL wrestled with it for awhile before he was comfortable with
        it too. In the end he decided it was fine.  
      UCB had previously objected to a request from someone
        on my team on ground of the EPL patent clause, so I think they
        just really don't like it.

            From the analysis by Christopher
              below, it would seem that a rather small
              addition/modification in the standard EPL could enable
              academic/research institutions to actively participate in
              Eclipse open-source projects. Whereas the current EPL
              patent clause seems to prohibit that. 
             
            
            Changing open source license terms is an extremely
            time-consuming and difficult thing to do. However, for those
            who are interested in such things there are on-going (but
            currently dormant) discussions about revising the EPL at  epl-discuss@xxxxxxxxxxx
            
             Personally I don't understand such
              legal details, but the issue encountered for UC Berkeley
              is probably widely applicable to many more US institutions
              (and European ones as well I guess). And it would seem
              that the Science IWG is specifically impacted by this as
              we're targeting research/academic instutions a.o. 
            
            UC Berkley is the first institution in 12 years to raise
            these concerns. I would not rush to any assumptions about
            their conclusions.
