Advantages: Cheap and potentially international

Disadvantages: Limited applicability (against copying of the particular artwork, layout or form of expression only); good only against actual copiers; can be difficult to prove existence, ownership and/or infringement, e.g. if records are incomplete

Costs: Low (professional advice on record-keeping/assignments may be required)
