About Me

I am a partner in Bird & Bird's Intellectual Property department in the Madrid office.

Having been an IP litigator for 22 years, my practice is focused on advising clients on the protection and commercialisation of intangible assets; the negotiation and drafting of licence and assignment agreements of trademarks, patents, utility models, designs, copyrights and trade secrets.

I have vast experience of filing judicial actions before the Courts regarding the infringement and validity of intellectual property rights and unfair competition in all fields of technology. I have significant experience enforcing standard essential patents/on FRAND litigation in Spain.

My clients include those in the Tech & Comms and Life Sciences sectors, whom I have advised on patent litigation, trade secrets litigation, protection and management programmes.

Prior to joining Bird & Bird in 2020, I was a partner at a Spanish IP firm.

I am the President of LES Spain and Portugal, and a member of EPLAW.
