Preventive Litigation and Due Diligence.

Commercial Arbitration. She was part of the team of lawyers that represented a well-known brewer in an arbitration proceeding before the International Chamber of Commerce (ICC), making innovative arguments in the matter of unfair competition.

(iii) For several years she was the key lawyer in the defense and protection of a major consumer goods company in what was known, within the legal arena, as “the potato chip war” (“la guerra de las papas”). Her involvement included not only a complex protection strategy, but also her participation in several proceedings, with positive results. (iv) She was also the lead attorney in the strategy to protect an iconic bottle of a certain tequila manufacturer (a three-dimensional trademark); this strategy included processing several administrative nullification and infringement proceedings before the Mexican Institute of Industrial Property (as well as their corresponding challenging procedures) against many products that intended to copy that bottle, thus avoiding trademark dilution.

Privacy and Data Protection.

This support included an intense effort to raise awareness on the issue of privacy and protection of personal data.
