Formed in 1994, Arochi Marroquín & Lindner is a young but large firm which is best known for its work in contentious matters. The firm specialises in IP and works with other law firms to advise clients on issues such as corporate and commercial, banking, foreign investment, tax and telecommunications law. It has about 35,000 files belonging to around 4,000 clients and approximately 80% of its clients are from outside Mexico. It represents brands including Colgate, Herdez and English language school Harmon Hall. "They are good litigators," said one competitor. "They have been tough opponents of ours." Another peer said: "Arochi is very strong in anti-counterfeiting. They are very good at arguing at the attorney general's office."
In October 2009, the firm convinced the Fourth Circuit Court to allow client Tequila Cuervo to register the trade mark Kryptonita, after the Mexican Industrial Property Institute (IMPI) rejected the registration on the grounds that the mark was descriptive.
