Patentsview's Plant Patents with non PLT classifications
This page used to work until the patentsview service stopped returning
uspc (uspto classifications). This error has been pointed out to them and
it's supposed to be fixed at some point. Until then you'll see "No longer published"
below. (The "No longer published" only applies to utility patents issued after
May 2015 and should not apply to plant patents or design patents). cpc's are also now being assigned
to plant patents but the service does not return them (more information
Here we send in a get request to the /patents endpoint with the following parameters:
&f=["cpc_subgroup_id", "patent_number", "patent_date", "patent_type", "patent_title", "uspc_subclass_id"]
In English that's asking for patents with a patent_type of Plant and a uspc_mainclass_id of
something other than PLT (categorized as something outside the PLT class), specifying a list of fields
to return please, and if it's not too much bother could the patents come back
with a primary sort by patent date descending and a secondary sort of patent number descending?
To make a spreadsheet analogy, we're asking for rows of sorted patent data where the columns are the ones specified in the "f" parameter. Pretty cool, huh?
Click a patent number below to bring up the patent at uspto.gov to see the USPC classification(s)
that the service should be returning!

When I originally wrote this patent 4356066 came back with G9B/5.288 which is particularly amusing as
it looks like that is a cpc!
