A drug patent is a patent issued by the patent and trademark often on the drug or some aspect of it.
Patents and exclusivity apply to drugs in different ways. Patents can be issued or expire at any time regardless of the drug's approval status and are issued by the patent and trademark office. Exclusivity attaches upon approval of a drug product if the statutory requirements are met and is granted by the FDA. Some drugs have both patent and exclusivity protection while others have just one or neither. Review the list of drug patents and drug exlcusivitis on our site to learn more.
Patents are typically 20 years from the date of filing. Based on the filing date and the drug approval date the patent life left after drug approval is much shorter than the 20 years.Search FDA exclusivity
