How long is a pharmaceutical patent good for?
20 years
In most cases, the patent is issued by the USPTO an average of 3.4 years after filing for a conventional drug and 4.4 years after filing for a biologic. According to statute, the granting of a pharmaceutical patent includes protection on that patent for a period of 20 years from time of patent filing.
What does it mean when a drug patent expires?
When a drug’s U.S. patent expires, manufacturers other than the initial developer may take advantage of an abbreviated approval process to introduce lower-priced generic versions. In most uses, generics are clinically equivalent to the original branded drug.
How do you extend a drug patent?
New Formulations, Administration Techniques, or Uses Another relatively straightforward way drug companies can extend a patent is by reformulating a drug – often to simplify dosing or how it’s administered. Extended-release versions of drugs are common ways companies reformulate products, for example.
How long until a drug becomes generic?
Once a new drug is approved, the FDA provides a guaranteed period during which a generic version cannot be approved, regardless of the time remaining on the new drug’s patent. This regulatory exclusivity typically runs for at least six years for new drugs.
What happens if patent expires?
An expired patent no longer affords the inventor or patent owner any protection. When the patent expires, the concept becomes available for any organization or individual to freely use, redesign, and market without the original patent owner’s permission.
Should drug patents be extended?

Are expired patents worth anything?
Expired, public domain U.S. patents can be a valuable tool for individuals and companies to learn what technology is available for use without fear of an infringement suit or licensing fees.
Why do drug patents last 20 years?
Due to the rigorous amount of testing that goes into a drug patent, many larger pharmaceutical companies file several patents on the same drug, aiming to extend the 20-year period and block generic competitors from producing the same drug.
Do drug patents increase innovation?
In fact, patents touch nearly every facet of biopharmaceutical innovation from initial drug discovery to new uses identified after Food and Drug Administration (FDA) approval, and most medicines are associated with multiple patents.
