Litigation Support Services

Argos Engineering provides litigation consulting in the areas of products liability and patent infringement. Argos' principal, Dr. John D. Pratt, has extensive experience with fasteners, latches and mechanisms, including manufacturing processes, standardization and performance. Dr. Pratt has also developed sophisticated analytical tools to analyze the influence of explosive decompression on aircraft interiors and structures.

Areas of Expertise

Profile

Argos Engineering provides new product development consulting for the Aerospace Fastener and Aircraft Interiors industries, as well as litigation consulting in the areas of mechanisms, latches and fasteners.

Argos' principal, Dr. John D. Pratt, has extensive experience with fasteners, latches and mechanisms, including manufacturing processes, standardization and performance. Dr. Pratt has also developed sophisticated analytical tools to analyze the influence of explosive decompression on aircraft interiors and structures.

As an aerospace industry executive in 2005, Dr. Pratt co-invented and led the development of the post-9/11 secure (terrorist-proof) cockpit door decompression latches now installed on half the world's fleet of commercial transport aircraft.

Before entering private practice in 2005, Dr. Pratt co-invented and led the development of the post-9/11 secure (terrorist-proof) cockpit door decompression latches now installed on half the world's fleet of aircraft.

Previously Dr. Pratt invented and commercialized the first viable blind fastening system for laminated composites. After 24 years, that system (Monogram Aerospace Fasteners' Composi-Lok©) remains the one of the most-used structural blind fasteners for composite airframe assembly and is the benchmark against which other fasteners are measured.

Dr. Pratt continues to work with Airbus, Lockheed, and Boeing on the development of improved fastening systems that address the challenges of robotic assembly, aesthetic appearance, and lightweight assembly.
