ABG Intellectual Property is one of the most respected IP firms in the Spanish market. The firm changed its name in 2018 from ABG Patentes to ABG Intellectual Property to reflect its full-service IP practice, which now includes a legal department. Patent protection and portfolio management is still the firm's core business, with a range of clients in technical fields such as pharmaceutical, chemistry, biotechnology and engineering.
Co-founder and European patent attorney Juan Arias, who has a background in chemistry, leads the firm. In the patents practice you will find experienced senior patent attorneys such as Pablo Calvo, Agustín Alconada, Fernando Prieto and Enric Carbonell. Prieto and Calvo lead on engineering and physics-related instructions while Alconada deals with biotechnology matters.
The firm has a team of lawyers and trade mark attorneys to deal with brand-related matters. European trade mark attorneys Christine Weimann and Inés Cantero Clivillé are the key practitioners in its trade mark practice. Weimann is in charge of the trade mark practice. Laura Montoya is responsible for the legal department. Iain A McGeoch and Marta Rodríguez are among the junior IP practitioners to watch.

Their proactive approach, coupled with their commitment to client satisfaction, has fostered a relationship built on trust and reliability. I confidently recommend this firm to anyone seeking exceptional patent representation.”
“In comparison with other firms (German) with whom we worked in the past, with ABG Intellectual Property we have a better response, in terms of promptness, and also a more complete analysis/answer of any request/question that we have.
