The PageRank patent is owned by Stanford; anyone can buy a license. And BTW, it isn't necessary or even that useful these days to compute it.

I'd thought that Google had an exclusive license, but I just checked and the exclusive license expired in 2011:

So yes, anyone can license PageRank now.

Right. But that is the prohibitive factor for many startups. They cannot afford nor are they willing to pay Stanford for PageRank.
