How can I ensure design protection in the USA?

The USA does not have a design registration system as such and it is necessary to apply for a ‘design patent’ in order to protect 3-dimensional wholly or partly functional designs. According to the United States Patent and Trade Mark office “Design patents may be granted to anyone who invents a new, original, and ornamental design for an article of manufacture.” Fees are expensive and it is advisable to instruct a local agent to draft and file the application.
