NZ also has non-use provisions for trademarks. Three years i think is the limit.
Also I have seen a lot of comments abput patenting ideas. You cannot patent an idea, but only an invention that carries out the idea. So for example you could not patent colour photography but only the method used to create colour photos. If someone comes up with another different method to do the same thing then your patent is not infringed.
On a completely different note, this is hilarious...
