Let me start with the second part of your question regarding whether there are best practices in other countries. Unfortunately, I would say the answer is no.
The U.S. recently had very high-profile litigation over the same issue. Their law is just as confused as ours is. We have a recent Federal Court of Appeal decision that complains about how confused the law is. The U.S. is very much in the same boat we are, except they're having more actual litigation. Europe has specific exclusions for certain things, for business methods in particular, but the way their legislation is drafted, it has proven to be unclear what they actually mean by it. It's something we can look to, but I wouldn't call it a best practice.
In terms of what should the framework be, are you asking me whether or not in my view business methods should be patentable?
