Patentsview's Oldest Plant Patents

This page is sending in a get request to the /patents endpoint with the following parameters:
q={"patent_type":"Plant"}
&f=["patent_number","patent_date","patent_title","uspc_subclass_id","cpc_subgroup_id"]
&s=[{"patent_date":"desc"},{"patent_number":"desc"}]

In English that's asking for patents with a patent_type of Plant, 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 ascending and a secondary sort of patent number ascending?

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? The problem is that currently no uspcs (United States Patent Classification) are being returned. See this page on plant patents with CPC (Cooperative Patent Classification) assignments which aren't being returned either.
