Thank you for your comment. What you say is true to a large extent, especially for medical applications, but does not apply to the whole of technology transfers from academia to industry...Many public research institutions do have patent portfolios and revenue sharing agreements with industry. Having said that, when I was in charge of all this at CERN, I advocated an impact-driven (rather than revenue-driven) approach to technology transfer... For a public research institution, spreading the news that we are saving lives is much more valuable than getting 1 million dollar per year in the bank...
The Web was invented at CERN, and they get no royalties whatsoever...
