hey will think about this - the solution is not extending patent protection but cutting it to conform to the world standard.
if your patent lasts 20 years you have less incentive to innovate. you make something new, profit for it for 19 years while you develop something else.
if your patent lasts 5 years you have to innovate faster and keep coming up with new things, to continue profiting.
shorter patent times speed development of new drugs, and reduce the costs to the poor, who benefit when cheaper generic copies become available once patent expires.
