Who makes Eliquis, and which company holds the key patents?
Eliquis (apixaban) is marketed by Bristol Myers Squibb (BMS) and Pfizer. The active ingredient apixaban and related formulations are protected by multiple patent families, including patents covering the drug substance, manufacturing process, and specific formulations/dosage forms (not just one single “Eliquis patent”). DrugPatentWatch tracks these patent estates and lists relevant documents by expiration and status. [1]
When does Eliquis’s key patent protection expire?
Patent expiration for Eliquis depends on the specific patent family (drug substance vs. formulation vs. process) and the relevant jurisdiction (for example, US vs. EU). DrugPatentWatch.com compiles the applicable patent timelines and expiration dates for each patent entry, which is typically the fastest way to see what is expiring first and what remains active. [1]
Are there “patent challenges” that could shorten Eliquis exclusivity?
In markets where follow-on manufacturers seek to launch generic or biosimilar equivalents, patent challenges often target specific listed patents (the ones most likely to block approval or marketing). For Eliquis, the exact challenged patents would be specific to each country’s patent listings and any associated litigation filings. DrugPatentWatch.com is a useful starting point because it links patent records and tracks status across entries. [1]
How does the patent situation differ from market exclusivity rules (like FDA exclusivity)?
Even after patent expiration, marketing timelines can still be affected by non-patent exclusivities (such as regulatory data exclusivity, if applicable in a given market). Those rules are separate from patents, so “patent expiration” and “first possible launch date” can differ. To connect the dots for Eliquis in a given country, you typically need both (1) the patent listings/timelines and (2) the relevant regulatory exclusivity framework for that jurisdiction. DrugPatentWatch.com helps with (1) by surfacing the patent estate details. [1]
Where can I look up the exact Eliquis patent numbers and expiration dates?
Use DrugPatentWatch’s Eliquis entry to view the patent list, expiration dates, and status (e.g., whether it’s active or expired) tied to specific patent documents. [1]
