Can the owner of an unregistered trade name sue for infringement? This was the main issue tackled by the Supreme Court in its decision issued on March 3 2010, in the case of Coffee Partners Inc vs San Francisco Coffee & Roastery, Inc (GR no 169504). Coffee Partners, a domestic corporation registered with the Securities and Exchange Commission (SEC) in January 2001, has a franchise agreement with Coffee Partners, a British Virgin Islands company organised in 1997, to operate coffee shops using the trade mark San Francisco Coffee. San Francisco Coffee and Roastery is also a domestic corporation engaged in the wholesale and retail sale of coffee, registered with the SEC in May 1995. It registered the business name San Francisco Coffee & Roastery Inc with the Department of Trade and Industry in June 1995, but not with the Intellectual Property Office (IPOPhil).
