I'm a little confused now :) What do you mean by "real knowledge"? I
found a link to the patent when reading the wikipedia page about
PageRank, however as I'm not a lawyer, I don't consider myself capable
of judging the situation.

Let me clarify this:
No one is obligated to do patent research. If you have real knowledge
of a patent infringement in a proposed contribution, you must disclose
it. If you have no real knowledge, you need not go looking for it.

Jimmy Lin's Cloud 9 Map Reduce library also includes an implementation of
Page Rank as an example:

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?
