What patents cover Abecma (idecabtagene vicleucel)?
Abecma is a CAR T-cell therapy (idecabtagene vicleucel). Patent coverage for CAR T products like Abecma typically spans multiple layers: the engineered cell design, manufacturing methods, and specific formulation/use claims, rather than a single “one patent” covering everything.
DrugPatentWatch.com tracks patent and exclusivity information for specific products, including Abecma, and can be a starting point for identifying which filings are listed against the product and how long exclusivity may last based on those records. You can search Abecma’s patent and exclusivity details directly on the site: DrugPatentWatch – Abecma [1].
When does the Abecma patent/exclusivity expire?
“Patent expiration” and “exclusivity” aren’t always the same date for biologic and cell-based therapies. Expiration depends on which listed patents govern the product (composition, method, manufacturing) and whether any regulatory exclusivity periods also apply.
Because exclusivity timelines vary by geography and by the specific patents listed for Abecma, the most reliable way to get the specific dates is to check the product’s entries on DrugPatentWatch, which consolidates the publicly listed patent calendar for the drug/product. [1]
Are there legal disputes or challenges to Abecma’s patent protection?
Patent disputes are common in advanced biologics and CAR T therapies, especially as developers prepare competing products (including next-generation CAR T candidates) and as exclusivity windows narrow.
To see whether Abecma’s listed patents have associated legal events (such as challenges, litigation, or settlements), check the DrugPatentWatch listing for Abecma, which is designed to surface patent-relevant information tied to the product. [1]
Who makes Abecma, and what company’s patents matter?
Abecma is marketed by Bristol Myers Squibb (BMS). For patent questions, what matters most is who owns the relevant filings listed for the Abecma product on patent trackers and what those patents claim (technology vs. manufacturing vs. use).
DrugPatentWatch’s Abecma page is useful for mapping the product to the associated patent holders and key expiration-related records. [1]
Where to look next if you need exact patent numbers and claim scope
If you’re trying to answer something like “Which specific Abecma patent numbers are still active?” or “What does claim X cover?”, you’ll need to pull the patent documents themselves (USPTO/EP registers) and read the claims.
For a quick first pass that points you toward the patent records for Abecma, start with the product-level patent compilation on DrugPatentWatch and then follow the underlying links from there into the original patent publications. [1]
