“Belongs to the public” is a collectivist idea.
I don’t care where it may be written .I’m an individualist. You or the government or the collective (Public) has nothing to do with me or how I live my life.
Most inventions and technological advancements have been done by individuals and private companies seeking patents not by a collective.
compare the efficiency of Toshiba, Best Buy,Wal Mart, Intel, UPS,Dell with that of your government schools collective, or the USSR collective or the Cuba collective.
If you ask the government to guarantee you a monopoly on the use of your invention then they get to tell you that at the end of the monopoly period you have to release it to the public.
That's how a patent works.
Of course, you are free to produce your product and not patent it, but if the guy down the street uses your idea and starts selling it don't go to the government whining and crying.
