Carlos Pérez is the Partner in charge of the Information Technology Law department for Fieldfisher in Spain.

He specialises in Technology Law and for more than 30 years has advised public, private, national, and international bodies with particular expertise in intellectual property, technology contracting and data protection. He advises technology companies, e-commerce businesses, pharmaceutical companies, non-governmental organisations, private non-profit-making foundations, insurance companies, retail businesses and public administrations.

Carlos participated in several legislative initiatives in Spain regarding intellectual property and data protection, taking part in the processes of preparing the Legal Protection of Software Act (1993), the Penal Code (computer crimes, 1995), in the draft bills to incorporate “Copyright” and “Enforcement” Directives (2002–2006), and in the drafts of the Organic Law on Data Protection [Ley Orgánica de Protección de Datos, LOPD] (1998 and 1999), the Information Society Services Act (2000–2002) and the developing regulations of the LOPD (2005–2007). He authored the Qualified Law on Personal Data Protection in the Principality of Andorra (2003–2004) and is drafting that country’s Electronic Signature Act.

Since 1992, Carlos has been the legal adviser and attorney responsible for legal affairs and actions in Spain for BSA | The Software Alliance. This has allowed him to gain extensive procedural and extra-procedural experience pursuing software-related intellectual property infringements, participating in lobbying activities with the Spanish government on a national, regional, and local level, in defending the intellectual property rights of companies in the business software sector, and participating in legislative initiatives in the field of software intellectual property.

He has given training courses to the Spanish Civil Guard and the Spanish National Police Force on software-related intellectual property, computer piracy and computer piracy prosecution techniques and managed the advisory service for one of the first banks in Spain to draft binding corporate rules for its multinational group structure in the field of international data transfers.

Carlos is an associate professor in master’s degrees, post-graduate courses and specialisations in my field of practice, particularly for ESADE business schools (2004 to present), ISDE (2015 to present), as well as the Bar Association (2014 to present), the University of Barcelona – IL3 (2013–2016) and the Magister Lucentinus at the University of Alicante (1994–1996 and 2017 to present).
