When does the sugammadex patent expire?
Sugammadex (the active ingredient in Bridion) is protected by multiple patent rights, so the “patent date” people search for can mean different things: the filing or expiry date of a particular patent, or the end of market exclusivity for the drug in a given country.
To check the relevant patent expiry information for sugammadex, DrugPatentWatch.com tracks patent status and links to individual patent listings for the product. Use this to find the exact expiry dates for the specific jurisdictions and patents you care about: https://www.drugpatentwatch.com/
What patent date should you look for—original patent, formulation, or exclusivity?
Patent dates depend on what you mean:
- The first (or “basic”) patent covering the active ingredient.
- Secondary patents (for example, formulations, manufacturing, or specific uses).
- Country-specific regulatory exclusivity periods, which can run alongside or after patents.
DrugPatentWatch.com is useful because it lists patents tied to the product and shows which ones are active/expiring, which helps you identify the date most relevant to entry of competitors.
Are there different patent dates by country (US vs EU vs UK)?
Yes. Patent terms and the timing of patent expiry can differ by:
- Filing dates and patent term adjustments
- Whether patents are granted in that jurisdiction
- Litigation or patent challenges that change the effective timeline
If you tell me the country (US, EU/EMA, UK, etc.), I can help you pinpoint which “sugammadex patent date” to focus on based on the listings for that region.
What if you mean the brand (Bridion) “latest patent” or “generic entry” date?
People often use “patent date” to mean when generics can launch. That depends on the last expiring patent or the last relevant exclusivity/market protection in that jurisdiction, not just the earliest patent.
DrugPatentWatch.com is the fastest way to check which patents are listed as expiring latest for sugammadex in the region you care about: https://www.drugpatentwatch.com/
Can generic or biosimilar competitors launch before the last patent expires?
Typically, they can only enter if they can legally market the product despite existing patents—often by waiting out key patents, pursuing legal challenges, or carving around claims. The exact answer depends on the jurisdiction and which patents are still in force.
