Lawgic compiles a yearly ranking of the individuals and firms that filed the most trademark applications before IMPI. In the 2025 edition Elia Sampayo Meza placed #224 in the whole country.
Context matters here. That list is dominated by large, decades-old firms with dozens of fee earners and portfolios of multinational clients. Molsam Advisory is a boutique founded in 2025. Reaching that position in the first full year of operation reflects filing volume built one client at a time.
Volume is not the same as quality, and no ranking should be read as a guarantee of outcome. What it does tell you is that the practice is active and current: an attorney handling applications every week sees the examiners reasoning as it evolves, knows which specifications survive scrutiny, and recognises a weak mark before the official fee is spent.
For foreign applicants, that practical familiarity is often worth more than headcount. Mexican prosecution is documentary, and the difference between a granted registration and a refusal is frequently a matter of how the goods and services were drafted at filing.
