Generally, when faced with competitor's illegal copying of a product's package, unless the design of such package is a registered design patent or a trade mark, the claimant used to rely on Article 22 of Taiwan's Fair Trade Act to seek injunctive relief. However, under the Fair Trade Act, there will be a heavy burden on the claimant to show to the judge that the asserted package is a "famous representation" that is "commonly known to the general public". Thus, if the design of a product package is eligible for copyright protection, it would be another powerful tool to combat copycats and free riders.
