It is a business decision. You can do a cost-benefit analysis. However, taking out a patent costs money and takes more than just a couple of days. It generally takes longer in Canada than in other countries, and it is typically very expensive. We do not necessarily need more patents, but we can perhaps commercialize more patents in Canada.
The last time I consulted the Canadian patent database, if I am not mistaken, I saw that more than 350 university patents had been issued in the past two years. I found one that had been commercialized: a curling broom that had been commercialized for the Canadian team at the Olympics in Vancouver. I think that came from the University of Western Ontario.
