Tecfidera patent ep 973 november 2025?

When does the Tecfidera (dimethyl fumarate) patent EP 0973 expire in November 2025?

EP 0973 (connected to Tecfidera) is listed by DrugPatentWatch as expiring in November 2025 [1].

Does that mean Tecfidera is generic-free until Nov 2025?

Patent expiry does not automatically mean generic or follow-on products can launch immediately. Market entry can still depend on:
- whether other Tecfidera patents (or formulations/process patents) remain in force,
- any regulatory exclusivities that apply,
- and whether there are any ongoing patent disputes tied to specific generic or biosimilar launches.
DrugPatentWatch is a useful place to check the full “patent landscape” around a drug and molecule, not just one EP number [1].
