Argos Engineering's principal, Dr. John Pratt, has earned 32 United States patents during his 36-year career in the Aerospace Fastener and Latching Mechanism business. He has served as Chairman of several domestic and international committees dealing with aerospace hardware and design allowables. During this time he has led the development of many aerospace systems, including the terrorist-proof cockpit door decompression latches used on half of the world's fleet of commercial transport aircraft. Other successes include the Composi-Lok I and II and Visu-Lok II blind bolts, and cylindrical-body Wedge Lock product lines.

As Chairman of the Industrial Fasteners Institute Technical Committee for Aerospace Fasteners, Dr. Pratt helped lead efforts to draft FAA-TSO-C148, and subsequently received the first FAA approvals under that regulation. Dr. Pratt also served as International Chairman of ISO / TC20 / SC4 / WG8, the organization for standardization of aerospace rivets, blind fasteners, lockbolts, and threaded pin-collar fasteners (i.e., Hi-Lites). In this capacity many of today's standards for metric aerospace fasteners were established.

Dr. Pratt's expert experience includes testimony in several patent infringement and products liability suits, as well as extended testimony before the Federal Trade Commission.
