Historic Intellectual Property
Would anyone like to play my hobby is weirder than your hobby? My hobby is
researching old patents, trademarks, prints and labels not all of
which are online hence the need for this website!
The tabs above correspond to the major categories of Historic Intellectual Property
I'm interested in. There's a glossary with definitions and spelled out
acronyms in case you aren't as far off the deep end as I am.
Be sure to check out the
Trademarks -> OCR Search. I believe this site is the only site on the internet
with this! Search over one million mostly dead trademarks. 0ver 60% of them are not in
the patent office's online Trademark Electronic Search System (TESS). Read more
about this here
Also the Patents -> Patentee Search is a uniquely created, though incomplete, list
of pre 1920 US patent holders not found anywhere else on the web!
Lately I've been playing around with the patentsview api and have documented
For the record I'd like to state emphatically that I have the utmost respect and
admiration for the United States Patent Office. They have made a staggering
amount of data available to the whole world. There is, however, a sliver
of data of keen interest to me that is not available either on their web site
or in any media they distribute. This site will attempt to A) make data available
here that isn't on their otherwise awesome web site and B) point out what data I
would like to get my hands on! And since historic IP should not be limited to the US,
I have recently added a searchable version of the
Canadian Patent Classification system
which was superseded right around the time the Berlin Wall fell.
Almost all of the missing online data has no legal standing and would only be
important to someone interested in Historic Intellectual Property.
Inactive trademarks, for example, have no bearing on current trademarks or
trademark applications and thus are given short shrift on the patent office's web site.
They are in the business of issuing patents and trademarks so this is understandable
Expired patents do have standing as Prior Art- something once patented cannot
be patented again. I have found a handful of expired patents, that are admittedly odd
and some that are extremely old, that are
not on the patent office's web site. I have made them available on this site.
(hint click on the Patents tab).
The google ads are a way for me to pay for this web site and hopefully to fund
the acquisition of more Historic Intellectual Property! Before going commercial
my Historic Intellectual Property online presence
was limited to nonesuchtools.com/patent
, and the
patent searching page
for the Midwest Tool Collector's web site.
