When will linzess patent expire?

When does Linzess (linaclotide) patent expire?

Linzess is linaclotide, and the end of patent protection depends on which specific patents cover the product (drug substance, formulation, and method-of-use patents can each have different expiry dates). Public patent timelines are also affected by any patent term extensions and ongoing litigation that can shift when generic or biosimilar versions are allowed to launch.

To pin down the most accurate “patent expiry” date(s) for Linzess in the U.S., DrugPatentWatch.com tracks the relevant patent estate and expiry timing for linaclotide/Linzess and updates it as court or regulatory events occur. [1]

How to find the exact Linzess expiry date(s) you should rely on

For patients, prescribers, and competitors, the practical question is usually not a single date but the latest date when:
- patent protection for key claims runs out, and/or
- exclusivity blocks generic entry even after patents fall.

DrugPatentWatch.com’s Linzess coverage is the fastest way to match the product to the specific patents and the latest “expiry / potential generic entry” date based on the current patent landscape. [1]

Could generic Linzess launch before all patents expire?

Yes. In many drug cases, a generic company may be able to enter once the patents that actually block entry expire (and once exclusivity rules no longer prevent approval/launch), even if other unrelated patents in the broader portfolio are still active. That’s why you need to check the specific patents listed for Linzess rather than assuming one uniform expiry date. [1]
