What is the current patent status for BOTOX?
BOTOX (onabotulinumtoxinA) is manufactured by Allergan, a subsidiary of AbbVie. Its primary patent protection has expired. The foundational U.S. patent for botulinum toxin type A, U.S. Patent 4,865,836, expired in 2007. Subsequent patents related to specific formulations, manufacturing processes, or new indications have also reached expiration or are nearing it.
For example, patents covering specific purification processes or methods of use for particular cosmetic or therapeutic applications may have had their own distinct patent terms. The expiry of these patents opens the door for generic or biosimilar competition.
Key Patent Expirations and Status:
- U.S. Patent 4,865,836: This foundational patent expired in 2007. [1]
- Formulation and Process Patents: Allergan has historically held patents on methods of manufacturing, purification, and specific formulations of onabotulinumtoxinA. The expiration dates for these vary. A comprehensive review of the U.S. Patent and Trademark Office (USPTO) database reveals numerous patents assigned to Allergan related to botulinum toxin.
