Fallout from the Squire and Patton Boggs merger didn’t end at the revolving door. Corn refiners, who had hired Patton Boggs years ago, opposed Squire Sanders’ representation of the sugar industry in litigation over the marketing of high-fructose corn syrup, a $12 million, five-year matter for Squire lawyers. A federal judge ruled in February that the combined Squire Patton Boggs could no longer represent Big Sugar in court because of the professional conflict. The warring industry groups settled after 10 days of trial in November.
