How is the period of patent term adjustment calculated?

The period of patent term adjustment is calculated based on various factors outlined in 37 CFR 1.703. The calculation includes:

  • Delays due to the USPTO failing to meet certain deadlines
  • Delays beyond three years from the actual filing date
  • Delays due to interferences, secrecy orders, and successful appeals

The MPEP states, “37 CFR 1.703 specifies the period of adjustment if a patent is entitled to patent term adjustment under 35 U.S.C. 154(b)(1) and 37 CFR 1.702.” The specific calculations are detailed in paragraphs (a) through (e) of the regulation.
