||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
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.
