One small point of clarification; patents are in fact a monopoly on the expression of an idea, not on the idea itself. At least that's the way it's supposed to work in the USA.
Technically, that's wrong. In the USA, copyright--not patent--covers expressions of ideas (http://en.wikipedia.org/wiki/Copyright#Idea-expression_dichotomy_an...), and patents cover inventions and processes. Neither is supposed to monopolize ideas in theory, but in practice they both do all the time.

You can reverse-engineer legally in the US (don't know about Canada), but you have to use clean-room techniques. That means that the people decompiling the code to create the specs can't be the same people recreating the code. That makes it easier to prove that there is no direct copying.
IANAL, but the makers of the Mac emulator named Executor employed lawyers, and then explained this in the legal section of their docs. Unless there had been a major revision in the law since then, this should still be the case.
Oh course this only applies to copyright. Patents are, by definition, a monopoly on an idea, not on its expression. The case referenced in the article above was an attempt for SAS to treat copyright law like patent law, but the rights each conveys are different, and the opinion above is that you can't get patent-like protections from copyright. I don't know to what extent software patents are allowed in the relevant jurisdiction, but if they exist then SAS should have used them instead. If they don't, then they are SOL.
Disclaimer: None of the above should be taken as an endorsement of software patents. I don't like them.
