Canada’s Patent Policy Is it the best stimulus for R & D?
After 15 years of enhanced patent protection the 2001 PMPRB states:
“the ratio of R&D expenditures to sales revenues for the patented pharmaceutical industry was 9.9% in 2001, down from 10.1% in 2000”.
“the R&D-to-sales ratios for all patentees and R&D companies were lower in 2001 than in any year since 1992”
