On August 6th, Google announced that https was becoming a ranking signal for Google Search.
I’m not completely sure of the implications of a discovery I made earlier today yet, but I noticed at the USPTO assignment database that Google had been assigned a patent from AT&T in June, which was officially recorded on August 8th, 2014.

The patent is:
Method for content distribution in a network supporting a security protocol
Abstract
Invented by Frederick Douglis, Michael Rabinovich, Aviel D. Rubin, Oliver Spatscheck Assigned to: AT&T Corp. US Patent 7,149,803 Granted December 12, 2006 Filed: June 8, 2001
The abstract from the patent is fairly simple, and tells us:
The present invention is directed to a method of providing content distribution services while minimizing the processing time required for security protocols such as the Secure Sockets Layer.
In short, it appears that there has been a cost in speed-related to the use of Secure Socket Layers security that the process described in this patent helps to speed up.
Is Google’s acquisition of this patent a matter of dotting all i’s and crossing all t’s?
I don’t suspect a profit motive in the purchase of the patent, but the nearness of the acquisition and the announcement of https becoming a ranking signal is interesting.
It is a sign of how careful Google has become when they consider whether or not something should play a role in the ranking of pages on the Web.
