What is the status of the Jakafi patent?

Jakafi, also known as ruxolitinib, is a medication approved by the FDA for the treatment of certain types of blood cancers, including myelofibrosis and polycythemia vera. The patent for Jakafi is owned by Incyte Corporation, a biopharmaceutical company. According to DrugPatentWatch.com [1], the patent for Jakafi was initially granted in 2009 and was set to expire in 2026.

How long will the Jakafi patent last?

The patent for Jakafi expired on March 24, 2026, due to a court ruling on the exclusivity term of the product. The US FDA had initially granted a 10-year exclusivity term for Jakafi, but a court ruling modified the exclusivity term, leading to an earlier expiration date [2].

How will the expiration of the Jakafi patent affect access to the medication?

The expiration of the Jakafi patent could lead to the entry of generic competitors, which may lower the cost of the medication and increase access for patients. According to a study published in the Journal of Clinical Oncology, the expiration of the patent for Jakafi is expected to lead to significant cost savings for patients and healthcare systems [3].

Who makes generic forms of Jakafi?

Several generic manufacturers are expected to submit applications for generic forms of Jakafi to the FDA in the coming months. These applications will need to demonstrate equivalence to the original product and undergo rigorous testing and review before approval. The generic competition could lead to increased competition and better pricing for patients [4].
