How many “US patent medicines” exist today?
There isn’t a single, universally accepted statistic for “how many US patent medicines are there today” because the count depends on what you mean by “patent medicines” (for example: only drugs protected by at least one active US patent, or any marketed drug still within patent/exclusivity life, or every US-listed NDA/BLA regardless of patent status). Also, different datasets track different coverage dates and update cadences, so totals can vary.
With only the provided context, I can’t produce a reliable, specific number.
What data source usually answers this (and why totals differ)
Companies and databases typically estimate counts using one or more of these building blocks:
- Marketed drug products (NDC-level, label-level, or application-level).
- Patent lists tied to those products (e.g., Orange Book listings for US patents).
- Patent status (active vs. expired, and whether a given product has “at least one” active patent).
Because those filters change, two answers can both be “correct” under different definitions.
If you meant “how many branded drug products still have US patent protection”
A commonly used way to measure this in practice is:
- Start with marketed prescription drug products in the US.
- Filter to those with active US patents (or active US exclusivities).
That yields a “still protected” count, but the exact number depends on which patent code types and what “active” means in the source.
If you meant “how many patents exist on medicines”
That’s a different question entirely: it counts patent documents (often far more than the number of medicines), and a single medicine can have many patents across formulations, methods, and device/combination claims.
Next step: clarify the definition so the number can be computed
If you tell me which definition you want, I can provide a more precise statistic using the right kind of dataset:
1) Number of marketed medicines (drug products) with at least one active US patent
2) Number of active US patents that cover medicines
3) Number of medicines within active patent or exclusivity windows (regulatory exclusivity, not just patents)
Also, do you want prescription-only, or all medicines (including OTC)?

No sources were provided with the prompt, and I don’t have enough information to cite a concrete statistic. If you share your preferred definition (or a link to the dataset you’re using), I can generate the correct, cited number.
