Supernus: Delays Out of the Applicant’s Hands Are Not Applicant Delays

The term of a U.S. patent is typically twenty years.  However, the patent term can be altered as a result of certain Patent Office delays (patent term adjustment) and certain regulatory delays (patent term extensions).  For the former, the Patent Office will adjust the term on a day‑for‑day basis: one day of delay results in one day of adjustment.  » Read More
