Intellectual Property Law in Ireland, 4th edition is a detailed guide to patents, copyright and trade mark law. It covers all relevant European legislation and traces its weaving into Irish law. It details European case law together with relevant case law from commonwealth countries, as well as detailing any Irish cases on the three areas and also covers design law. It outlines the workings of the patents, copyright and trade mark offices in Ireland. It is laid out in a practical and user-friendly way, with each section separate, but cross-referenced where necessary.

Since the previous edition, only six years ago, there have been a number of fundamental changes to a number of aspects of intellectual property law, which make this new edition essential. The areas that have been expanded and updated in this edition include:
- The voluminous European case law on IP issues arising since 2010
- The impact of the new EU TRade Mark Regulation No 2015/2424
- Supreme Court decisions on the law of passing off (McCambridge Ltd v Joseph Brennan Bakeries) and unregistered design rights (Karen Millen Fashions v Dunnes Stores)
Along with these, the book looks to future and the developments on the horizon. It tracks the ongoing domestic copyright law and Digital Single Market, as well as discussing the potential benefits of the the Trade Secrets Directive (EU) 2016/943
