I disagree ... without and period of copyright, there would be no profit incentive, and hence no reason to innovate
A short period of copyright for creative works (maybe 2-5yrs) is required to establish identify the original creative artists.
In Australia, there is legal dispute concerning a gene pattern that is a key indicator in several different cancers (approx 15% of cases) .... This DISCOVERY is to the benefit of all mankind, however the company that DISCOVERED it has patented the knowledge & forced several hospitals using equipment searching for this gene in cancer patients to stop the screening.
I would suggest that this is morally reprehensible, given that the company hasn't released products to use this knowledge in the several years since DISCOVERY.
I could understand a patent for equipment and processes ... but for a DISCOVERY?
The patent world has overstepped it's bounds, and is no longer server the interests of mankind. Some heavy regulation is required.
