Dr. Martens wants to stomp out copycats. AirWair International Ltd., the Wollaston, England-based manufacturer and marketer of Dr. Martens footwear, has sued Chinese Laundry for illegally selling shoes that it claims look too much like Dr. Martens. AirWair has a litigious history. Last year, the company took to court to stop Vans Inc. from selling shoes it asserted infringed on its trademarks.
