Good news for those who love Atom and AtomPub as Google announced that they are removing any patent implications to help further adoption.
We've always encouraged other developers to adopt Atom, the Atom Publishing Protocol, and the extensions that Google has created on top of those standards, but we realized the issue of patents may have held back some adopters. Well, those concerns end today as we are giving a no-charge, royalty-free license to any patents we have that you would need to implement Atom, AtomPub, or any of those extensions.
I'm a fan of the AtomPub API and we (MuleSource) use it for Mule Galaxy. I had been a bit concerned about how Google would treat companies that were using it in products but this certainly alleviates any anxiety.
Microsoft should take a lesson from Google (as is often the case) and not just show the APIs but actually allow developers to use them without risk.Google's license text.
