On coverage of Design Patents (US)
Posted: Mon Sep 26, 2016 8:10 pm
Hello,
First of all, thank you for OPS and Espacenet. These are great services and extremely useful.
So, my problem is that I've been searching some specific Design Patents from USPTO without success.
For instance:
http://patft.uspto.gov/netacgi/nph-Pars ... er=D267676
http://patft.uspto.gov/netacgi/nph-Pars ... er=D271895
http://patft.uspto.gov/netacgi/nph-Pars ... er=D311138
http://patft.uspto.gov/netacgi/nph-Pars ... er=D375756
http://patft.uspto.gov/netacgi/nph-Pars ... er=D401820
(please note that these patents are in patft, then corresponding to granted patents)
Unlike other granted design patents, I'm unable to find those using OPS (neither Espacenet). Each of the following requests return "status: not found":
http://ops.epo.org/3.1/rest-services/pu ... 76S/biblio
http://ops.epo.org/3.1/rest-services/pu ... 95S/biblio
http://ops.epo.org/3.1/rest-services/pu ... 38S/biblio
http://ops.epo.org/3.1/rest-services/pu ... 56S/biblio
http://ops.epo.org/3.1/rest-services/pu ... 20S/biblio
So, I digged into it a little and found something interesting.
According to this report [1] there are more than 500k granted Design Patents (summing column "Design Patent Grants" from 1976 to 2015).
However, according to bibliographic coverage [2], there are ~330k Design Patents (row where IDs contain "USD"). Also according to information on this page, data ranges from 1865 to 2016.
There are, indeed, pretty old and pretty recent Design Patents, as can be seen in the following endpoints:
http://ops.epo.org/3.1/rest-services/pu ... 67S/biblio
http://ops.epo.org/3.1/rest-services/pu ... 40S/biblio
So, my question is: what is the reason for the (apparently relevant) number of missing USPTO Design Patents? Is there something in common on these cases?
