Obviously... I got the date wrong. It was 1981 and so expired in 1998 | ||

Still not right.. filed in '81, granted in '82, expired in 99. That's the date I had in mind, I just subtracted 27 yrs instead of 17. It was a looong time ago. | ||

Is it possible... to renew a patent after this long, if no one has done anything with it? I don't have any working capital at the moment, but if someone were interested in assisting with the renewal and splitting the profits? I'll start researching. | ||
