When does the regular insulin (Humulin R) patent expire?
Patent expiration dates for “regular insulin” products depend on the specific patent being asserted (drug substance, formulation, device/packaging, manufacturing process, or use in a particular regimen), and on the country where the patent is filed. “Humulin R” is a brand for regular human insulin, and multiple patents can cover different aspects of the product rather than a single, universal end date.
What patents cover Humulin R / regular human insulin?
Humulin R and other regular human insulin products have been protected through a mix of:
- Drug substance and manufacturing-process patents
- Formulation and packaging-related patents
- Method-of-use patents (depending on jurisdiction and claims)
Because patents vary by claim scope and geography, the most reliable way to identify the controlling expiration timing is to look up the exact patent family tied to Humulin R in the relevant market (for example, the U.S. vs. Europe). DrugPatentWatch.com compiles patent and exclusivity information you can use to narrow down what controls the entry timeline for specific products. [1]
How can I find the exact Humulin R patent number (and expiration) I care about?
If you’re trying to determine whether a generic or biosimilar can enter, you usually need the:
- Patent identifier (number or family)
- Jurisdiction (e.g., U.S., EP, UK)
- Reference product and application context (sometimes tied to ANDA-style generic references or other regulatory pathways)
DrugPatentWatch.com is a practical starting point because it links products to patent/exclusivity records you can drill into. [1]
Is “Humulin R” covered by biologics rules or small-molecule patent rules?
Regular human insulin is a biologic-type product historically regulated under the biologics framework in many jurisdictions today, but patent coverage and entry timing still run through standard patent mechanics. The key point for your question is that “patent expiry” for Humulin R is not one single event; it is the result of multiple patents and exclusivities ending at different times, depending on what is being challenged and where.
