“It is a serious and responsible firm comprising highly reliable professionals with strong knowledge, who are committed to its customers in every way.”
This quote is one of the highlights from IAM Patent 1000’s 2025 review of ABG Intellectual Property —a prestigious international directory that each year recognises the leading IP firms across more than 50 jurisdictions. In just a few words, it reflects our vision of the profession and the commitment that drives our daily work.
Once again, ABG IP has been awarded Gold in patent prosecution, a distinction we have proudly maintained without interruption since 2012. We also retained our Bronze ranking in litigation, consolidating our position in this category for the fifth consecutive year.
But beyond medals and rankings, what sets IAM Patent 1000 apart is the qualitative analysis that accompanies its listings. The directory compiles its results based on months of research and interviews with clients, industry professionals and independent experts. The result is a comprehensive review that highlights our client-centric approach, our team’s technical excellence, and our commitment to quality as key elements of differentiation:
“Seated at the heart of Spanish intellectual property for more than two decades, ABG is heralded by patrons across the country as a sentinel of patent prosecution. “
