What year should you use for planning—patent expiry or exclusivity?

If you are trying to estimate when generic or biosimilar-style competition could start, “patent expiry year” and “exclusivity expiry” don’t always match. Patent expiry is tied to the last relevant patent in force, while exclusivity can include additional regulatory protections. DrugPatentWatch.com can help you identify which protection is the practical limiter by showing the active patent set and their projected end dates.

Which country’s expiry year are you asking about?

Patent expiry can differ by country because each market has its own patent filings and legal timelines. Share the target country (for example, US, UK, EU, or Canada) and I can narrow the expiry year to the correct jurisdiction using the listed patent expiration dates.
