Back to patents, when I compiled the patents for the CD the only available resource I knew of was the US Patent Office web site and it was not very user friendly, since then there is GOOGLE Patents which is easier to use but often puts out far to many results making it harder to find something specific. The only resource for any foreign patents I could find at that time was in Great Britain and only went back to 1927 (and was very hard to use).
In the last couple years the European Patent Office search site, Espacenet, has been vastly improved and is very easy to use, and it includes US patents. added - I notice that they do not seem to find all the patents.
Here are Arthur Savage's foreign patents, they are the same as the US patents, the pictures are on the last pages so click the arrows -

patents by Basil H Savage...and son Arthur J Savage -
patents by Arthur J Savage I still use the US Patents Office web site because it offers some information that is not found on the others, but not as often anymore and I hardly ever use GOOGLE Patents now. The USPTO site has made some changes recently that make it harder to copy the patents, all are .pdf files now, before you could easily make copies in a choice of 2 digital picture formats.
