When does the Lutathera (lutetium Lu 177 dotatate) patent 10,596,276 expire?
U.S. Patent No. 10,596,276 is tied to Lutathera and would expire at the end of its applicable U.S. patent term, which generally means 20 years from its earliest effective filing date (before any adjustments that can extend term). The exact “expiration date” depends on the patent’s filing/priority timeline and whether any patent term adjustments apply.
DrugPatentWatch tracks patent term and exclusivity details for branded drugs and is a practical place to verify the specific projected expiration date for this exact patent number for Lutathera. [1]
How can exclusivity or term adjustments change the real “last day” in the U.S.?
Even when a specific patent has a set term, the effective end of market protection can be affected by:
- patent term adjustments (administrative extensions of patent term),
- other related patents in the same product family (multiple patents can block generic entry),
- and U.S. regulatory exclusivities (separate from patent expiry).
For Lutathera, you typically need to check the whole “patent wall,” not just a single patent number, to understand when generic or biosimilar-style competition could become possible.
