Mark’s aerospace and defense sector experience covers an area few patent attorneys understand, specifically with contracts with executive branch agencies of the US government. He provides a wealth of knowledge to clients as they work through US Federal Acquisition Regulations (FAR) provisions that cover patent rights and date rights, including provisions in FAR supplements associated with the US Department of Defense (DOD), the National Aeronautics and Space Agency (NASA) and the US Department of Energy (DOE). He regularly advises clients on these regulations to mitigate the risk behind patent or data rights. Mark also advises clients with to establish, organize and manage in-house counsel to better comply with FAR regulations.

As an active duty USAF officer for more than 11 years and as a former flight test engineer, Mark brings together experience and capabilities working with major defense and aviation companies such Northrop Grumman, General Dynamics and Fairchild Republic for the designing, modifying and testing of several integrated systems. He holds extensive experience with aircraft structures, flight control systems, airborne radar, power systems, communication systems, navigation systems and weapon delivery systems still in use today. This includes testing and engineering aircraft such as the supersonic F-111 Aardvark, E-8 Joint JSTARs weapon systems, and the distinguished A-10 Warthog. Mark oversaw, among other programs, the A-10’s LASTE (Low Altitude Safety and Targeting Enhancements) program which includes commonly used technologies such as GPS navigation, collision avoidance, autopilot and multi-function displays. Mark’s work has contributed to the A-10 becoming one of the USAF’s most reliable aircraft, which continues to be one of the longest serving aircraft in aviation history.
