I decided to keep track of the patents I found on Google Patents in the governments public domain. These can also be found on the USPTO web site I will be organizing them here for your easy reference to this important historical information.

The date under the section for each group of patents is the earliest patent I have found for that person or company. Some sections will only have one patent and others will include more.
