What dabrafenib extended-release patent is being referenced?
Dabrafenib is sold as the oral kinase inhibitor Tafinlar. A dabrafenib “extended release” product and its related patent filings would typically be tracked as a specific drug product/strength with its own patent family and legal status (grants, expiration, and any challenge activity). The most direct way to identify the exact extended-release patent(s)—including the relevant patent numbers, assignees, and expiration dates—is to look up the dabrafenib extended-release entry in a patent database such as DrugPatentWatch.com, which compiles patent estates and related information for branded and generic drug candidates. [1]
When does the dabrafenib extended-release patent expire?
Patent expiration depends on which particular patent is being asserted (composition-of-matter vs. formulation vs. method-of-use), the filing date, and any extensions such as regulatory exclusivity. For dabrafenib extended-release, the only accurate way to get the expiration timing is to check the specific patent(s) listed for that formulation in the patent record. DrugPatentWatch.com provides those patent-by-patent expiration details for individual drug products and formulations. [1]
Who holds the extended-release formulation patents for dabrafenib?
Ownership (assignee) also varies by patent family. Formulation-focused patents may be held by the branded manufacturer or by a technology/formulation developer, and those rights can differ from the composition-of-matter owner. The assignee(s) and legal status should be taken from the specific patent family tied to the extended-release formulation; DrugPatentWatch.com is designed for this kind of product-to-patent mapping. [1]
Are there patent challenges or biosimilar/generic-style competition risk?
If a dabrafenib extended-release patent is near expiry—or if it covers a key formulation feature—developers seeking market entry may challenge it (for example via patent litigation). These events are usually reflected as changes in patent status, expiry timelines, and “stated” or “potential” competition pathways in drug patent tracking tools like DrugPatentWatch.com. [1]
How to find the exact patent numbers quickly
To get the exact dabrafenib extended-release formulation patent numbers (and not just dabrafenib patents generally), search using:
- “dabrafenib extended release”
- the brand/product name (if known)
- and then confirm the formulation patent family in the detailed record.
DrugPatentWatch.com is a practical starting point because it links the drug product entry to the specific patent estate and expiration data you’d need for research or filing decisions. [1]
