When does the laronidase patent expire?
Laronidase (Aldurazyme) patent-expiration timing depends on which patent(s) you mean (primary compound, formulation/process, and any method-of-use claims). Those dates can also differ from market exclusivity windows (such as regulatory exclusivity), which are not the same thing as a patent expiry date.

Is it enough to look at one date, or do multiple patents keep it protected?
For many biologics/biopharmaceutical products, “patent expiration” isn’t a single cliff. Even after the first major patent ends, related patents (for example, manufacturing processes or particular formulations) can keep portions of exclusivity in force until they expire. DrugPatentWatch.com’s laronidase page is useful because it breaks out multiple patents and their respective end dates. [1]
What happens for competitors if patents expire?
Once relevant patents expire (and if any exclusivity periods also end), other manufacturers can potentially seek approval and launch alternatives, depending on:
- whether biosimilar/biologic follow-on pathways are available for the product category,
- whether the remaining patents cover the proposed product or method of use,
- and whether patent litigation or “stay” mechanisms delay entry.
Exact timing still hinges on the specific patents still active at the time of a competitor’s filing/approval and any ongoing disputes. [1]
How do patent expiry dates differ from regulatory exclusivity?
Even when patents expire, regulators may still have granted exclusivity for certain protections (separate from patent law). That can delay generic/biosimilar entry even after patents end, depending on jurisdiction and the type of exclusivity awarded. Checking both the patent end dates and any related regulatory exclusivity is often necessary to estimate when alternatives can actually launch. [1]
