Answer 2

Patent owned by Stanford from Wikipedia.

The name "PageRank" is a trademark of Google, and the PageRank process has been patented.

However, patents are employed at Stanford University but not from Google. Google has exclusive licensing rights at Stanford University patent Instead of using patents.
