Forty years ago, people were dancing to Stayin Alive by the Bee Gee’s, munching on Reese’s Pieces for the first time, and watching John Travolta & Olivia Newton-John in Grease, and Jamie Lee Curtis in Halloween (the first one!). A lucky few were playing Space Invaders on their Atari 2600, or DOS-based games on their Apple II computer; and the iPhone was not yet a glint in Steve Jobs’ eye. Coincidentally, forty years ago the mark “GUILD INVESTMENT MANAGEMENT” (GIM) was being used by Guild Investment Management, Inc. for investment advisory services while the mark “GUILD MORTGAGE COMPANY” (GMC), owned by Guild Mortgage Company (Guild), was being used for mortgage banking services.[2] Nevertheless, decades later an application for the GMC mark in International Class 36 was refused by the Examiner, who argued that there was a likelihood of confusion with the GIM mark because “the marks, nature of the services and trade channels were similar.”[3] The Trademark Trial and Appeal Board agreed, despite finding that “consumers ‘may exercise a certain degree of care in investing money, if not perhaps in seeking a mortgage loan.’”[4] Guild appealed to the Federal Circuit.
