Re: Power Attenuator I have several patents in digital electronics filed through the Eastman Kodak Company and, as a result, have a fair amount of experience dealing with the patent process and the Kodak patent attorneys. It has been my experience that you don't have to change very much at all in a design that is considered "prior art" in order to be granted a patent. Also, keep in mind that patents (and the exclusive rights they imply) are only valid for 17 years. Therefore, there is (and was) nothing stopping Mr. Pittman from using 40 or 50 year old prior art as a "springboard" for his own invention. The Japanese have been doing this with American technology since the end of WWII! The VCR and SLR cameras are excellent examples of this. However, Mr. Pittman's patents DO prevent US from copying his design exactly and going into production with it, unless, of course, he officially licenses the technology to us. Dave |
