Re: [aspectj-users] AOP patent question 
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."

I asked this same question a while ago. Search the mailing list for the

Does anyone have any guidelines as to how one can reasonably use AspectJ
or AOP?
