Water-from-Air Patent Links

Patents sorted by year of issue
Patents issued by the U.S. Patent and Trademark Office (USPTO), can be downloaded by clicking on the link. A new tab (or page, depending on your browser settings) will open in your browser for the URL www.pat2pdf.org. Please follow their simple instructions. They stated on their site, "pat2pdf.org exists thanks to the support of volunteer programmers that have kept the site free and running (as much as possible) over several years." I encourage users of their service to donate to pat2pdf.org periodically (at the URL www.pat2pdf.org) to ensure that their valuable service continues making it easy to access USPTO patent information. Atmoswater Research has no financial interest or connection with pat2pdf.org but is simply recommending its services to the water-from-air community.

At this time, there is no similar easy method to make links for downloading pdf's of non-USPTO patents.
