I'll first of all respond to Mr. Harrison's question, which I wasn't able to respond to before.
The sole purpose for filing a U.S. provisional as a first step for an inventor is simply to establish a priority date. It's the formal application that is actually driven by market size.
The second point I would like to make is that we need the IP regime in Canada to allow Canadians to get the benefit of technologies developed here and to give them a reason to stay here and grow here.
Further, without a predictable patent regime, investments won't happen and investors will not invest in our Canadian companies.
