RE: [aspectj-users] AOP patent question

["Donal Lafferty" <laffertd@xxxxxxxxx>]

Does it really matter what the CPL says?  If Xerox decides that it's
going to remove the AOP patent from the CPL, and sue the next person who
goes to 'create derivative works' by recompiling a bug fix, who's going
to pony up the case (US$500,000+) required to fight a patent law case?

fyi, Jim Hugunin's 3/20/2003 reply to "Patent on AOP/AspectJ?" was this:

------
PARC's goal in releasing AspectJ in Open Source form on eclipse.org is 
to ensure that the community can continue to use and develop AspectJ. 
We believe that the Common Public License (CPL) used by eclipse is an 
effective way to do this.  By contributing the AspectJ source code under

the CPL, PARC also licenses any relevant patents under the terms of the
CPL.

If you want a non-legalese description of what the terms of the CPL are,

I'd recommend reading the eclipse legal FAQ 
(http://eclipse.org/legal/legalfaq.html).  Here's what that FAQ says 
about patents, "Under the CPL, each Contributor grants rights to create 
derivative works and for worldwide, royalty-free software redistribution

in accordance with the CPL terms, including a royalty-free license to 
use Contributor's patents as embodied in its contributions."
