Our deep knowledge of the local market helps our clients to protect and develop their IP assets.

You don’t need to be told that safeguarding and exploiting your IP assets can be crucial to maintaining a competitive edge. At Deacons we understand what is at stake, and have the experience to help you to get the most from your IP assets.

Don’t take our word for it. As well as numerous top band rankings for IP in independent directories such as Chambers Global, Legal 500 Asia Pacific and Managing Intellectual Property, and success in major awards, our track record of leading cases and ‘firsts’ speaks for itself. As Hong Kong’s largest and longest-established IP practice we were involved in registering Hong Kong’s oldest trade mark in 1874, as well as making its first ever e-filings of trade mark, patent and design applications.

Today we work with some of the world’s largest brands in the electronics, telecoms, pharmaceuticals, fashion, luxury goods, media/entertainment, software and computer hardware industries – including 50 of the world’s top 100 brands as identified by Interbrand PLC   – so you can be confident that in trusting Deacons you are in excellent company.

Our experienced team offers a seamless service across Hong Kong and China covering all areas of contentious and non-contentious IP work, including Hong Kong, China and international trade marks, copyright and design rights, patents, domain names, data protection, technology, e-commerce, advertising and broader brand protection issues. We have an impressive record of success in litigation and enforcement actions in Hong Kong and mainland China. The Deacons (Beijing) Intellectual Property Agency, which was founded in 2013 under the sole ownership of Deacons, works closely with the team in Hong Kong to help clients establish and strengthen their overseas businesses while also assisting them with protecting and developing their valuable IP portfolios.

Whether you are doing business in Hong Kong for the first time, or understand its business environment perfectly, it is still good to know that you are in safe hands. It is good to know, for example, that Deacons is the largest full-service independent law firm in Hong Kong, as well as the longest established.

Since 1851 we have been developing a unique culture, which blends traditional client care with modern technology and working practices. Our integrity and dedication to the highest service standards is matched by our cosmopolitan nature and commitment to innovation. Deacons’ clients receive:

  • Top quality advice in 16 key service areas;
  • Access to the experience of our 49 partners and over 200 lawyers;
  • The resources of our international networks;
  • Three representative offices in mainland China; and
  • The benefit of our deep knowledge of, and relationships with, Hong Kong’s business community, built up over many years.

It is no surprise that our achievements have been recognised by respected publications, such as Chambers Asia-Pacific and Asian Legal Business, including being voted ‘Hong Kong’s Law Firm of the Year’ and ‘Employer of Choice’ on numerous occasions.

What really matters to us, however, is what our clients think. And they tell us that what they appreciate most is our ability to understand their businesses and time pressures, and to act as ‘trusted advisors’ in helping them to take crucial business decisions.
