Goes beyond that by far I'm afraid. Imitation or fake only matter when a "Brand" has not been attached or implied to a specific product. In the same vein, products may contain proprietary parts or be wholly proprietary, they may be covered by one or more patents and as such, their replication, either knowingly or otherwise, may leave both the vendor and customer in hot water. In effect, replicas can only be applied to goods that don't have a patent or brand. You can make Asprin and Paracetamol but can't brand a can of Fizzy Pop as Coke. I suspect that you can't produce Imitation Burberry and get away with it either as the material is technically a Brand and although not "clear cut" may, if an operation got too big, lead to some "court time" at best.
