PATENTS
Expertise rooted in science
At PURDYLUCEY, our patent team brings together the rigour of scientific training with in-depth knowledge of intellectual property law.
Many of our attorneys began their careers as researchers, engineers, or scientists, so we speak the language of innovation fluently.
Whether your breakthrough is in biotechnology, AI, engineering or medical devices, we understand the underlying technology and translate it into strong, strategically drafted patents that support your commercial goals.
Practical, strategic support from concept to grant
A patent is more than a legal document — it’s a business tool. From early-stage invention capture to global filing strategies, we help our clients protect and leverage their IP in ways that create real-world value. Our approach is practical and collaborative: we work closely with in-house teams, founders, and inventors to identify what’s patentable, assess where to seek protection, and build robust portfolios that support long-term growth.
Trusted by innovators, respected by peers
PURDYLUCEY represents clients before the Irish, UK and European patent offices, acting for domestic companies as well as international associates seeking a reliable European partner. We’re proud to work with start-ups, universities, research institutions, and global businesses who rely on us not just for efficient prosecution, but for ongoing guidance in a complex and fast-moving IP landscape. Our success is built on trusted relationships, scientific credibility, and a deep commitment to protecting what matters most—your innovation.
