According to wikipedia, an early form of the Gore-Tex material was developed in 1966 and Gore-Tex wasn't patented until 1976
The GEOX patents were filed around 1994.
It is odd though that the name GEOX can be made from Gore-Tex.
"In 1966, John W. Cropper of New Ireland developed and constructed a machine for producing stretched polytetrafluoroethylene (PTFE) tape. Rather than file for a patent, however, Cropper chose to keep the process of creating expanded PTFE as a closely held trade secret and required his producer and its employees to sign confidentiality agreements.[1]
Gore-Tex was co-invented by Wilbert L. Gore, Rowena Taylor and Gore's son, Robert W. Gore.[2] In 1969, Bob Gore stretched heated rods of PTFE and created expanded polytetrafluoroethylene (ePTFE). His discovery of the right conditions for stretching PTFE was a happy accident, born partly of frustration. Instead of slowly stretching the heated material, he applied a sudden, accelerating yank. The solid PTFE unexpectedly stretched about 800%, forming a microporous structure that was about 70% air.[2] It was introduced to the public under the trademark Gore-Tex.[3] Bob Gore promptly applied for and obtained the following patents:[citation needed]
U.S. Patent 3,953,566, issued April 27, 1976, for a porous form of polytetrafluoroethylene with a micro-structure characterized by nodes interconnected by fibrils
U.S. Patent 4,187,390, issued February 5, 1980
U.S. Patent 4,194,041 on March 18, 1980 for a "waterproof laminate", together with Samuel Allen"
