It's critical to keep up with local laws when managing an international trademark portfolio. Recently, due to amendments to the Regulations of the Mexican Industrial Property Law, parties doing business in Mexico and seeking protection for word marks and slogans there should know whether they will qualify for word mark protection.
To qualify as a word mark, that mark must be composed only of characters or letters corresponding to the Roman alphabet (e.g., A, B, C...), Arabic Numbering (e.g., 1, 2, 3...), and orthographic symbols which help correctly read the mark (e.g., - , . ' ¿? ¡! " " ...).
If marks include other symbols (e.g., & # @ \ + ...) the Mexican IP Institute will require amending the mark to a Design Mark. This may not seem like a major issue, but filing properly will save time in prosecution and help you avoid potential pitfalls down the road.
