Testimonials

  • ‘I have worked with Dentons in London, Chicago, and Washington DC, mainly on trade mark matters. They have provided excellent service to us for many years.’

  • ‘Anna Brown runs a very good trade mark team in London and in Dublin. We have worked and been happy with Sinead Mahon.’

  • 'Their ability to combine technical excellence and deep knowledge of the intricacies of legal disputes with practical commercial awareness, not least in prioritising the client's branding interests, truly set them apart.'

  • 'We only regret that our teamwork could not last for longer, but very much look forward to collaborating with them again in the future!’

  • ‘Jennifer Cass has deep experience in, and understanding of, brand-related disputes and her client's branding interests, which has been impressive to observe.'
