In mid-July the FDA released their June 2019 (Vol. 39, Supp. 6) Orange Book raw data. Here are a few observations about Supplement 6: There were 47 new patents listed in June. Only four of the newly listed patents had traditional compound claims which does not include new polymorphs, salts or hydrates. One patent was delisted in June.

In that way I did not have to make major changes to the downstream computer code. For my update of the OBA to include 2018 expirations I decided to bite the bullet and make the major revisions that would allow my code to use the FDA’s current data file format directly. No more retrofitting of the new
