I'll try and explain the patent in it's most basic form. I think the only thing being patented is the 225 ranking component which consists of 2 things (405,410).
1.) The set location component (405) - This is the equation used to classify websites affiliation with each other and organizing the search results based on affiliation (I'm guessing it's how Google knows which sites to show in it's results when you do a search). The only thing mentioned on how they will actually identify affiliation between documents (websites) is in FIG. 4
This is what it says: "the determination of affiliation can be based on the link graph structure of the documents, traffic patterns to the documents, or similarity of features such as the hostname or the IP address of the documents. (
http://en.wikipedia.org/wiki/Graph_theory )
As another example, in the context of the web, the link graph structure of the documents can be used to measure affiliation between web documents based on the strength of the linkage between web sites hosting the documents.
Additionally, traffic patterns on the web can be used to detect affiliation between web documents that are visited by many users in the same session. Still further, the IP addresses of two web servers can be compared and if the leading two or three components (octets) of the ID address are identical, affiliation can be inferred."
2.) Rank Computation Component (410) - This is the actual equation that is applied to Google's databases of search results to determine how to order the affiliated documents (search results).
It looks like the rankings given for a set of affiliated documents is done in 3 phases utilizing different equations and be done in any order and as many times needed. Refer to FIG 6-8 to see the equations.
Even though we know the equations we don't know all the variables Google takes into account. (They wouldn't share that anyways because it would give others an unfair advantage)
Everything else mentioned in the patent is just to demonstrate how Google's 225 ranking components will work. It has nothing to do with what you do on your computer or anything else this video talks about.
I believe Google just had to properly demonstrate how their software operates in a real world situation for it to be applicable. This goes for any patent.
There is absolutely nothing to worry about based on my thorough investigation into this patent.
If the creators of this video want to release the other patent they mention I will be more than happy to go through it.
