Thank you very much for the advice, I'll try to contact Stanford then.

As a contributor, you could submit a patch noting the existence of the
patent, *If you know that a patent reads on it*. As a PMC member, I'm
advised by legal-discuss@ to reject the patch, unless you can get a
grant from Stanford.

However, 'having heard' is not the same thing as *knowing*. A vague
rumor does not trigger any of this.

The fact that CMU has chosen to distribute an implementation is
neither here nor there.

Hello everyone,

I have a question regarding legal issues.

I have one of my students implement PageRank in MapReduce, would it be
possible to contribute this to Mahout or are there any legal issues
prohibiting this?

I read that Stanford is holding a patent on PageRank but I've seen a
PageRank implementation already included in the Pegasus Framework from
Carnegie Mellon University which is Apache licensed.

Can someone help here with advice?
