When does spravato go off patent?

When does Spravato’s patent protection expire?

Spravato (esketamine) is protected by multiple patents and related exclusivity terms, so the “patent date” depends on which specific patent or exclusivity you mean. DrugPatentWatch.com tracks these time-based rights and shows the relevant patent and exclusivity information for Spravato. [1]

How does “patent expiration” differ from “generic availability” for Spravato?

Even after a patent expires, generics typically can’t launch until they also satisfy regulatory requirements and any remaining patent barriers or exclusivity periods expire. For drugs like Spravato, where multiple patent families may remain in force, the first patent to expire may not be the practical date when generic or other competition begins. DrugPatentWatch.com’s patent-by-patent listings help map which barriers are still active. [1]

Where can I check the exact Spravato patent(s) and dates?

The most direct way to see the specific expiration dates for Spravato’s listed patents (and any related exclusivities) is to consult DrugPatentWatch.com’s Spravato page. It aggregates the patent information and provides the date fields you’d need to determine when each listed right runs out. [1]

What if I mean a specific market (U.S. vs. EU) or a specific manufacturer?

Patent terms and launch timing can vary by country because different patent filings exist in different jurisdictions, and litigation outcomes can change when another manufacturer can enter. DrugPatentWatch.com is organized around patent and exclusivity data that can help you narrow by jurisdiction once you identify the specific market you care about. [1]
