Patent Attorney

I have nearly 20 years’ experience in Intellectual Property Practice (Patents, Trade Marks and Designs) and I joined PURDYLUCEY in 2009 following several years working as a Patent Attorney in another Intellectual Property firm in Ireland.

As well as being a European Patent Attorney and Irish Registered Patent Attorney, I am also an Irish and European Trade Mark and Design Attorney.

Prior to entering the Intellectual Property profession, I obtained a B.Sc. (Hons) in Biotechnology from Dublin City University and a M.Sc. in Brewing and Distilling from the International Centre for Brewing and Distilling at Heriot Watt University in Edinburgh.

I have a wealth of patent experience primarily specialising in the filing and prosecution of Patents in the fields of biotechnology, food science and nutrition, environmental science and medical devices. Alongside this, I also have extensive experience in Patent litigation including domestic Patent litigation and infringement issues and in representing clients at oral proceedings, including Patent opposition proceedings, before the European Patent Office.

As a Trade Mark Attorney, I deal with all aspects of national and European Trade Marks including pre-filing advice and searching, as well as Trade Mark filing, prosecution, opposition, revocation and invalidation. I regularly advice on Design matters and am also involved in the filing and prosecution of European Community Registered Design applications.

I am a Member of the Association of Patent and Trade Mark Attorneys.

  • 'Co-founded by established attorneys Barry Purdy and Michael Lucey, PurdyLucey is forging a strong name thanks to its ''superb pool of prosecution nous''. It is particularly noted for its prowess in Purdy's chosen field of biotechnology, making it a prime choice for life sciences clients. This concentration is complemented by Lucey's success in his electronics and software specialism.'
