Entec requests Inter Partes Reexamination

Entec Engine of Atlanta has filed for an inter partes reexamination of Caterpillar’s patent no. 6,651,618.  The patent, titled “Air and Fuel Supply System for Combustion Engine,” issued in November 2003.

In February 2004, USPTO Under Secretary Jon Dudas held a roundtable to discuss the equities of inter partes reexaminations.  A PDF version of the transcript from the roundtable discussion is available here.
