Forward Citations

Is this data available?  That is, can I query a patent number and ask for all of its forward citations?

http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=7654321.PN.&OS=PN/7654321&RS=PN/7654321

Click on "Referenced By"

Obviously, "backward citations" are static and "forward citations" are dynamic (could update weekly).  But the mapping is a link-type map, so should be easy to implement.

Is it currently available?  Will it be available soon?

RE: FORWARD CITATIONS

Hello,

Thanks for reaching out! You can use the "cited_patent_id" field to query the API and get back a list of the forward citations. For example: http://www.patentsview.org/api/patents/query?q={"cited_patent_number":"7861317"} will return the forward citations to patent 7861317. On the website there is a list of different fields you can query for forward citations by (for example, you can get forward patent citations by patent category). That information is here: http://www.patentsview.org/api/patent.html#field_list.

This will give you the forward citation data up to the latest update date (in this case 12/26/2017) and will be updated every time the data gets updated (which will be about quarterly).

Best,

PVTeam
