Google PageRank Patent Expiring

It “appears” they first lose exclusivity in 2011 and then the patent expires in 2017.

Interesting. :slight_smile:

I wonder what “exclusivity” would mean. Could it mean that other sites could publicly display pagerank? (which you alread see). Could it mean other sites could use the word pagerank or have their own ranking system?

It means they can have what Google uses as “PageRank”- the original pagerank algorithm/code thats was patented by Stanford University.

Stanford can give a license of use to anyone it wants. Google doesnt own the coding, or the name.

For a “hefty” sum (your probably talking over a million dollars), Bing can aquire a “license” to Pagerank, and then call their version “Bing Pagerank”

Look at it like this:

say you create a Forum or video/gaming script. You then “license” it, and someone says “hey, Ill give you 5 thousand dollars if you license it to me exclusively for 5 years” For the next 5 years you cannot give a license to anyone else to use your created script.

When that 5 years expire, you can give/sell a licensed copy of your script to whomever you want, and they can install/run it just as the first guy did that had an “exclusive” 5 year license.

No - Google founder Larry owns the name as it was named after him.

Presumably when other sites start using it they will name their copy after one of their founders. Perhaps Microsoft will call their version GatesRank.

That is incorrect

Stanford owns the name, and the patent to “PageRank” and Stanford is officially credited as the “inventor” of the technology. Page and Sergey of Google just “lease” PageRank" and the name from the university, and aquired a “license” of Use. They own no rights to it at all. Stanford owns the technology, and they own the name. They can license the name “PageRank” to anyone they choose, and Google has no say so at all as they [Google] have no other claim to the patented technology other than a perpetual “license” of use- which is rendered a non-exclusive license in 2011.

All rights belong to Stanford including the Patent for “PageRank” itself.

Form 10-k (2009) filed with United States Securities and Exchange Commission

Page 15

The first version of the PageRank technology was created while Larry and Sergey attended Stanford University, which owns a patent to PageRank. The PageRank patent expires in 2017. We hold a perpetual license to this patent. In October 2003, we extended our exclusivity period to this patent through 2011, at which point our license will become non-exclusive.

A patent under US Law:

A patent for an invention is the grant of a property right to the inventor.

Since this “PageRank” was done at Stanford, under their grants, with their money they automatically obtained full rights to the “patent” in question- that means they control full rights, as well as the name to the patented technology (which is in this case called “PageRank”).

Hope that clears up your evident confusion regarding the name “PageRank” and who owns it.

I am certain that Larry was using the name Page for many years before it was applied to that ranking algorithm. So he can easily claim prior use regardless of anything else since it is simply a ranking algorithm named after him.

Stanford may own some rights to the single word version of the name but most people usually make it two words “Page Rank” and the second of those words is being used for its normal meaning while the first of them is a reference to Larry and so Stanford can’t claim any rights at all to that version of the name.

That is why Larry calls it “Google PageRank”

Under the patent, the technology (owned exclusively by Stanford) is named “PageRank”

With any patents done in universities, and funded exclusively by them, the technology (and its name) is aquired by them.

Since in this case the technology is called “Pagerank”, and Stanford holds the patent to said technology, they also have full rights to the name of the technology.

Its the same as any person’s name that is also part of a company’s name or the name of a patented product, when they sell/or otherwise lose the rights to the patent/company they also lose the rights to the company/patented name-larry Page has no legal rights to the patented technology called “PageRank”, and as i have said before, Stanford can license “PageRank” to anyone it wants- and they can use the name “PageRank”

For example, “Hershey’s Chocolate” is the name of a person (Hershey) it is patented as a confectionary, and as the name of the confectinary company. If that patent/company is aquired by another, then they have full rights to use the name “Hershey’s” as they see fit. Hershey himself (the person) loses the right to that name as a patented commercial name…in other words, he cannot turn around and start another company called “Hershey’s Chocolate” just because Hershey is his name, and “chocolate” is a kind of food, and unpatentable.

Hershey’s (company) can then turn around and release “Marshmellows”, and they have every legal legal right to call it “Hershey’s marshmellows” because they own the confectionary patent and its name.

If Bing, purchased a license to the PageRank technology from Stanford, they have every right to call it “Bing PageRank”, or even “Bing Page Rank”, “PageRank”, or just “Page Rank” if they so desire.
