AFAIK a person can make a part for them selves that someone else holds a patent on. Right"
For myself, not for resale.
Correct ?
Also, basic engineering concepts such as levers pulleys, jack shafts are not even patent able, right?
The debate is, - Someone holds a "right" to a jackshaft"
I would think there has to be a patent number on it...or something?
Anyway, i disagree.
These things are up for grabs as part of engineering concepts.
thanx in advance !
