Sorry, it is *NOT*, at least not for patents in the U.S.  I think you're
confusing it with copyright. A patent is an exclusive right to manufacture
and sell. Independent reinvention is no defense. (Neither is "obviousness",
at least, once the patent has been granted.)

Many companies (including one I worked for back in the early 80's) who
made CRT display terminals were surprised to get a little letter one day
from RCA because it turned out that RCA had a patent on (roughly) storing
fonts in ROM, and they wanted a cut from every terminal you shipped.
We had good patent attorneys. We still paid...  :-{
