Patent Term Adjustment For Divisional Patents

The 20-year term of a patent issuing from a divisional application is measured from the filing date of the parent application.

United StatesIntellectual Property

Most of the Patent Term Adjustment (PTA) cases being filed in the U.S. District Court for the Eastern District of Virginia involve patents issuing from applications in which a Request for Continued Examination (RCE) was filed, and cite the November 1, 2012 decision of Judge Ellis, III in Exelixis. (That decision, and a conflicting decision from Judge Brinkema, are on appeal at the Federal Circuit.) A recent PTA complaint filed by Mr. Mohsenzadeh caught my attention, because it raises a different issue: should PTA be awarded in a divisional application when the USPTO took longer than 14 months to issue a Restriction Requirement in the parent application?

The Patents at Issue

The patents at issue are U.S. Patent 8,352,362 and U.S. Patent 8,401,963, directed to methods of transferring resources from one entity to another, and related methods. These two patents stem from divisional applications of U.S. Patent 7,742,984.
