We anticipate risks, negotiate solutions, and defend trademarks, patents, designs, trade secrets, and other intangible assets when a dispute requires us to take action in court.


“Elzaburu has an active litigation practice that complements its recognized expertise in the processing and management of patents and trademarks.”
As an agency, law firm, and consulting firm, we have a comprehensive understanding of each asset—from its protection, management, monitoring, and exploitation to its defense. This holistic approach allows us to provide advice on trademarks, patents, designs, copyrights, and other intangible assets from legal, technical, and strategic perspectives.
Since 1865, we have been providing advice on industrial and intellectual property, building up expertise on how these assets are created, evolve, and are protected. In addition to this hyper-specialization, we bring more than 30 years of experience in court proceedings and a team of attorneys recognized in national and international rankings.
Our approach is preventive: we analyze risks, prepare legal opinions, reports, and preventive briefs, negotiate agreements, and seek the most effective way to prevent conflicts from escalating.
When legal representation is necessary, we appear before Spanish courts, the General Court, and the Court of Justice of the European Union, coordinating legal and technical teams to address each matter from every angle and achieve the most favorable outcome in each case.
