About Us

Rouse was established in the UK in 1990, and is recognised as a global Intellectual Property leader operating as a closely integrated network with more than 1000 people working out of 43 offices in 19 countries.

We focus exclusively on IP, from strategic consulting, patents and trade marks through to domain names, copyright, designs and geographical indications. And we’re experts in providing services for each stage of their life cycle.

We have a deep understanding of all jurisdictions around the world and a strong focus on more challenging markets such as Africa, Asia, the Middle East and Russia. Most importantly, we’re passionate about IP and enjoy working with clients who share that passion. We put clients at the heart of our business and build long standing relationships. From large multinationals that want our scale, quality and professionalism, to start ups that value our entrepreneurial spirit, the companies we work with come from a broad range of sectors with diverse business interests and needs.

The Rouse Difference

Rouse prides itself on its quality and professionalism, but we have also always dared to be different. We don’t believe that all firms should be the same. That’s why we’ll always challenge the traditional way of doing things if we think another way is better.

It also means we don’t just advise on the law - in many countries we help define and shape it. We have a practical, pragmatic and “unstuffy” approach, with teams of professionals who work closely together across functions and geographical borders in a non-hierarchical, creative and results-oriented environment.

Rouse people are full of energy and enthusiasm. We are passionate about IP, our business and our people, and we genuinely enjoy what we do. We believe that having fun provides a happier, more productive working environment.

Whatever your needs, in whatever country, we have either an established Rouse office or a long standing relationship with a local firm.

The Rouse Network consists of local subsidiaries of Rouse International Limited and closely aligned but independent firms which work seamlessly together on engagements. Which elements of work are done by which entity depends entirely on the country in which work is carried out, in compliance with relevant legal and regulatory provisions.
