The biggest pitfall of them all is lack of novelty. If your competitor or yourself or your manufacturer or your distributor already sell the product. In other words, if you seek European design registration after the product hit the market. In this case the design patent may not be new at the time of application. Later, this could lead to the cancellation of the design patent. It is important to tell us about this, as it is an important aspect. Please also mention foreign design patent applications, because they need to be coordinated.
