BindingDB Data Curation

BindingDB curates US Patents. We have scanned patents back to 2013 for suitable data and are currently up to date as of mid-2020. However, we cannot be sure of capturing all relevant patents, so if you know of a useful one we have missed, please let us know and we will try to curate it. As of September 18, 2021, BindingDB's patent dataset comprises:

  1. Patents: 5,025
  2. Binding measurements: 748,866
  3. Compounds: 375,047
  4. Target proteins: 2,118
  5. Assays: 7,278
  6. Average Number of Targets per Patent: 1.92

BindingDB curates a set of journals not covered by other public databases. As of September 18, 2021, the status of this curation effort is as follows:
