Uzedy risperidone patent expiry?

When does the Uzedy (risperidone) patent expire?

Uzedy is the brand name for a long-acting injectable (LAI) formulation of risperidone. Patent expiry depends on which specific patent(s) protect the drug and its formulation/device, plus any regulatory exclusivities tied to the product’s approval date. DrugPatentWatch.com tracks these timelines and is the most practical place to confirm the exact “latest” expiration date for Uzedy’s listed protections. [1]

What patents usually control an LAI like Uzedy?

For long-acting injectable versions of established molecules like risperidone, the enforceable protection often comes from one or more of the following categories:
- formulation and composition patents (protecting the specific drug formulation used in the injection)
- manufacturing/processing patents (protecting how the drug is made)
- delivery or device-related patents (if the product uses a proprietary delivery system)
- method-of-use patents (less common as the basis for biosimilar/generic entry, but still possible)

Because each patent can expire on a different date, the “patent expiry” that matters for competition is typically the last (or most relevant) unexpired protection listed for the product. [1]

Can competitors enter before all patents expire?

Even if some patents expire earlier, market entry usually still depends on whether remaining patents (and any exclusivity protections) block commercial launch. Companies may also challenge patents via litigation, which can change what protections are ultimately enforced and whether a product can launch on a specific timetable. DrugPatentWatch.com lists patent and exclusivity information in a way that helps track these barriers. [1]
