Matheson’s specialist Intellectual Property practice is geared to meet the demands of our clients.  Ireland is a key European business hub, and there is an increasing amount of inward investment involving intellectual property rights.  We advise a diverse domestic and international client base on both contentious and commercial intellectual property matters.  We also advise on the intellectual property aspects of many of the largest corporate transactions taking place in Ireland.

We offer a dedicated Intellectual Property team within our Technology and Innovation Group, as well as having Media and Entertainment, Life Sciences and Retail and Leisure teams.  The specialist nature of our Intellectual Property practice groups enables us to offer a focused industry-based expertise while also providing strategic and expert intellectual property law advice and litigation services.  Led by Deirdre Kilroy, an IP practitioner of many years' experience, the group comprises dedicated IP lawyers who are committed to delivering pragmatic, commercial and concise advice to our clients.

The Group advises on corporate intellectual property due diligence reviews and strategic portfolio advice, and the acquisition / divestment and licensing of intellectual property rights, as well as preparing and implementing corporate intellectual property protection programmes, the international re-structuring of IP rights, and advising on employee rights and corporate ownership of intellectual property rights. 

The Group’s expertise in branding and trade mark includes branding and trade mark protection programmes, trade mark filing and prosecution through Matheson trade mark advisors, trade mark and get-up licensing, protection of image and personality rights and business reputation.  In conjunction with our Commercial Litigation and Dispute Resolution Department, the Intellectual Property Group also advises on trade mark infringement and passing-off disputes, and anti-counterfeiting and customs registration.

The Group’s practice includes advising on copyright, designs and databases, including computer game protection advice and licensing, registered and unregistered designs, database rights, Internet and domain names, Internet based trade mark and copyright infringement, website intellectual property risk management, international domain name protection strategies and domain name disputes.

We also advise on strategic patent protection and commercialisation advice, research and development agreements and technology licensing, and patent ownership, infringement and validity disputes.

Lawyers in the Intellectual Property Group take an active role in local and international organisations concerned with the development of intellectual property law.  Organisations in which we are involved include the International Trademark Association (INTA), International Association for Protection of Intellectual Property (AIPPI), Licensing Executives Society (LES), MARQUES (The Association of European Trade Mark Owners), Pharmaceutical Trade Marks Group (PTMG), Domain name dispute resolution services administered by the World Intellectual Property Organisation (WIPO) Arbitration and Mediation Centre and by the Czech Arbitration Court, and the Intellectual Property Law Committee of the Law Society of Ireland
