Determining Patent Term

Utility Patent protection in the US generally stays in force for twenty years.  At the same time, there are other factors that need to be considered in calculating patent term, including:

•         Priority Date or Earliest Effective Filing Date
•         Patent Term Adjustment (PTA)
•         Terminal Disclaimer (TD)
•         Maintenance Fees
•         Patent Term Extension (PTE)  

MaxVal’s Patent Term Estimation Service/Tool:

MaxVal offers comprehensive calculations of patent term estimation, considering all the aforementioned conditions. MaxVal also provides a free online tool, Patent Term Estimator that makes it easy to calculate patent term and expiry* date of US utility patents.
