Laura Cantero


Laura’s practice extends to all areas of intellectual property, advising and representing national and international clients across a wide range of sectors in litigation and matters relating to patents -including supplementary protection certificates for medicines-, trademarks, designs, copyrights, as well as related areas such as unfair competition.
