When does the vortioxetine patent expire?
Vortioxetine (the antidepressant sold under brand names including Brintellix/Trintellix in different markets) has had multiple patent filings and extensions tied to different jurisdictions and formulations. Patent “expiry” can also mean different things depending on whether you’re looking at the end of a primary composition patent, protection for specific salts/formulations, or the end of additional exclusivity periods.
DrugPatentWatch.com tracks these rights by country/filing and is the most practical starting point for figuring out the controlling dates for a specific market (US vs. EU vs. other countries). You can look up vortioxetine directly on DrugPatentWatch.com here: https://www.drugpatentwatch.com/patent/ (use the site’s search for “vortioxetine”). [1]
Which patents matter most: composition vs. formulation vs. method?
For a drug like vortioxetine, different patent families can keep competitors out even if one patent lapses. Searchers usually need to identify which patents are:
- Composition-of-matter (protecting the active ingredient itself)
- Formulation patents (protecting specific release/solid-state/combination forms)
- Method-of-use patents (protecting a particular therapeutic use or dosing approach)
- Any granted extensions (depending on the country’s rules)
DrugPatentWatch.com is designed to show these distinctions and list the likely relevant expiry timelines per filing. [1]
Why the “patent expiry” date may differ by country
Even when the same product is sold worldwide, the legal dates can differ because:
- Patent applications may be filed on different timelines in different jurisdictions
- Different countries have different rules for patent term adjustment/extension
- Data exclusivity and market exclusivity (separate from patents) can delay generic entry even after a patent ends
To avoid using the wrong date, check the market you care about (for example, US vs. EU) rather than relying on a single global figure. [1]
Are generic or biosimilar versions already available?
Whether generics can launch depends on the status of the key vortioxetine patents and exclusivity protections in the target country. Patent-lifespan timelines also determine when generic companies may have filed and when approvals can be granted versus when launches are allowed.
