Quiénes somos

The firm J. LAHIDALGA is made up of two generations of Official Industrial Property agents,

D. José LAHIDALGA RODRIGUEZ and
D. José Luis LAHIDALGA DE CAREAGA,

Our firm has specialised exclusively in Industrial and Intellectual Property since 1955 , both in research and in consultancy, as well as providing legal services such as legal assistance or defence.


Our collaborators are qualified to operate in different areas of the profession such as:

  • OFFICIAL INDUSTRIAL PROPERTY AGENTS before the Spanish Patent and Trademarks Office (SPTO).
  • EUROPEAN PATENT AGENTS (European Patent attorneys) before the European Patent Office (EPO) in Munich.
  • ACCREDITED REPRESENTATIVES before the Office for Harmonisation in the Internal Market (OHIM), (Trademarks and Designs) in Alicante.

At the same time we are members of various different Organisations, both Spanish and foreign, of which we would like to mention the following:

  • “COAPI”.- Official College of Industrial Property Agents in Spain.
  • “AIPPI”.- International Association for Protection of Industrial and Intellectual Property.
  • “AGESORPI”.- Spanish Association of Agents authorised before International Organisations for Industrial and Intellectual Property.
  • “INTA”.- The International Trademark Association in the U.S.
  • “EPI” .- Institute for Professional Representatives before the European Patent Office. (Munich).

Our head office is in Madrid, but we also have offices in Alicante, Santiago de Compostela, León, Murcia, Málaga and Palma de Mallorca.

Due to the International aspect of our business, we have a wide network of Agents and lawyers all over the world that have shown their professionalism and adaptability to our style of working. These relationships have grown over the years into a sizeable and reliable exterior network which allows us to offer a first rate service to our clients outside Spain, as well as in business and business consultancy.

It goes without saying that we offer these same services to any and all of our collaborators' clients.

Our staff is made up of engineers, economists, chemists and lawyers who have a wide experience in the sector. Our work tools are among the most advanced, allowing us to offer our clients great speed in the procedures, for example being able to carry out the registration of a trademark in up to half an hour.

As we are connected “on-line” with the main National Patent and Trademark Offices in the world, as well as having access to the most relevant databases, we are able to offer search results in really short spaces of time, which in turn allows our clients to take decisions equally fast.


Important note.

All our transactions are guaranteed by J. LAHIDALGA, experienced Industrial and Intellectual Property Agents, inscribed in the list of legally recognised agents in the Spanish Industrial Property Office, and members of the official College of Industrial Property Agents, and therefore acting under their code of practice. This means that not only do we have the necessary qualifications, but that we also have the mandatory guarantees and insurance for civil responsibility.

For this reason we urge you not to trust “representatives” or “consultants”, as there is not any provision for these professionals in the current Trademark Law, (Law no. 17/2001 of 7 th December).

Our name is our only presentation card, we do not hide our transactions behind fancy trade names or initials.

We reply to each enquiry personally
