Mimmo, Thanks for the information. I think I have a much better idea of what your strings are. A couple of points: >You said: "I do not see any problem if in the sport's field someone calls >tennis cords in that way. Why not?" With all due respect to both of you, I would think that M. Rosinfiorin's discussion on this matter would indicate the problem caused by this confusion. >You said: "What exactly is Nylgut? I do not answer to this question." I don't know about Italy, but if you have a patent in the United States, the formula is public information, available to anyone from the U.S. patent office. That is the nature and in part the purpose of a U.S. patent. Craig
