A ‘very reliable’ IP boutique, Castellanos & Co scores highly for its ’clarity and assertiveness in responses’. Founded in 1960, the long-established firm enjoys strong relationships with domestic and multinational clients, as well as international law firms, and has recently undertaken matters for Alpen Pharma, American Airlines and Interra Energy. Among its practice sweet spots, the group is primarily recognised for its focus on patent and trade mark prosecution — where it is well versed in search and opinion work and administrative litigation — and can draw on the support of four patent engineers. Managing partner Ximena Castellanos heads the trade mark prosecution team and provides ‘prompt and efficient attention’; she successfully represented Corporación Habanos in protecting the “HABANOS” mark in opposition proceedings. Margarita Castellanos leads the patent and legal departments and is noted for her expertise in Colombian patent prosecution law; she also has a strong record in administrative litigation concerning trade marks and other distinctive signs.
