Chris Baker, data scientist at the Virginia Tech Applied Research Corporation, developed the patentsview R package that is a wrapper around the PatentsView API. It contains a function that acts as a client to the API (search_pv()) as well as several supporting functions. Full documentation of the package can be found on its website.

The library offers ways to query the API, process the data, and develop visualizations to track interesting patterns in patenting activity. For analysis examples that go into a little more depth, check out the data applications vignettes on the package's website.
