LK Shields Solicitors LLP and Byrne Wallace LLP merged at the beginning of 2025 to form Byrne Wallace Shields LLP. The intellectual property team has a robust track record in assisting clients with contentious and non-contentious matters. The team frequently handles trademark and design rights litigation, including passing-off and infringement claims. The non-contentious practice covers design protection, IP commercialisation, due diligence, and licensing, with a particular focus on the pharmaceutical and life sciences sectors. The practice is co-led by Colin Sainsbury and Mark O’Shaughnessy. Jane O’Grady is frequently sought out by clients for assistance with R&D and licensing agreements.
