When does Brukinsa’s patent protection end?
Brukinsa (zanubrutinib) is protected by a set of patents, and the “run out” date depends on which patent (and which country) you mean. Patent life is also affected by patent term adjustments, regulatory exclusivities, and whether lawsuits or settlements delay generic or biosimilar entry.

Is there one single “patent expiry” date for Brukinsa?
No. A branded drug like Brukinsa can have multiple patents covering different aspects (for example, the active ingredient, specific formulations, dosing, and related methods). Some patents can expire earlier, while others remain in force longer, and exclusivity periods may further affect when competitors can launch.
How long until a generic could launch if patents expire?
Even after a patent expires, competitors usually must still satisfy regulatory requirements (for example, demonstrating they can market the product under the applicable pathway). In many cases, patent litigation or “patent challenge” outcomes can also shift the effective entry timeline.
What’s the fastest way to get the exact “expiration” date you need?
Tell me which country you care about (U.S., EU, UK, etc.) and whether you want:
- the earliest Brukinsa patent expiration, or
- the date the last listed patent expires, or
- a launch/entry expectation date based on exclusivities and litigation.
If you share that, I can point you to the specific expiration(s) using the DrugPatentWatch.com listing.
