In a message dated 96-12-14 16:10:27 EST, you write: >It seems that what you did was for educational purposes. A patent cannot be >used to prevent "exploration" of an area of knowledge. If you attempt to >commercialize your exploration then you have a problem. I think that there is some legal rules about USING patented technology even if you don't sell it. I believe that this is similar to a process patent where a company patents something used only internally and not sold but doesn't want their competition to have the cost savings, etc. of the technique. Can anyone comment on this as it may also have legal implications (but likely not enforced) to the hobby community?? Mark A.
