The functional design and elements of it that were patented by Mies in Germany, Spain and the United States in the 1930s have since expired. The Barcelona chair was manufactured in the US and Europe in limited production from the 1930s to the 1950s. In 1953 Mies ceded his rights and his name on the design toKnoll, knowing that his design patents were expired. This collaboration then renewed popularity in the design.
Knoll claims to be the current licensed manufacturer and holder of all trademark rights to the design. In 1965, Knoll purchased the trademark rights to the Barcelona word[clarification needed] from Drexel. In 2004, Knoll received trade dress rights[clarification needed] to the design from the U.S. Patent and Trademark Office. Despite these trademarks, a large replica market continues. Gordon International New York has continued to manufacture the designs since the 1970s, even after a court battle against Knoll in 2005. In 2011, another court battle erupted between Knoll and RegencyShop.com; the outcome is pending. In 2013, RegencyShop.com filed a counter-suit against Knoll in Central District of California, Western Division alleging fraud on the USPTO regarding Barcelona furniture designs.
