Patent Litigation

ALG is the market leader in patent litigation in Ireland, representing clients in the most significant patent infringement and invalidity actions before the Irish Commercial Court. We regularly collaborate with leading international law firms on Irish aspects of pan-European and US patent litigation.

Our integrated team combines legal and technical expertise to deliver comprehensive advice, excelling in tackling complex and technical work under tight deadlines. We advise clients on both day-to-day patent defensive and offensive strategies and pre-litigation matters, across various sectors including technology, life sciences, telecoms, and electronics, drawing on over 20 years’ experience in patent and SPC litigation.

We keep clients ahead of local and international patent law developments and have a stellar reputation for handling high-value cases, including licensing, R&D collaborations, and contractual disputes before the Irish High Court.

Our team’s technical qualifications and international experience enables us to develop and implement effective patent strategies tailored to Ireland and key global jurisdictions.
