Yusarn Audrey LLC is a boutique intellectual property and corporate commercial law firm that focuses on all aspects of intellectual property and how it can be used as a strategic tool for businesses and transactional support to monetise intellectual property.  Here, the firm’s corporate and intellectual property lawyers, as well as in-house patent agents and technical specialists, work together for seamless delivery of intellectual property and legal services around the single objective – creating, protecting and realising value from our clients’ IP assets.

We organise our firm and services around this central idea: that intellectual property is a powerful business asset and must be managed strategically. Everything that we do for our clients must help them create, protect and harness this valuable resource – intellectual property.

In addition to this, we have developed new intellectual property strategic advisory services as tools to ensure that our clients’ IP activities support and enhance their business strategies and objectives. By helping them to begin managing their IP in alignment with their business and mission, our clients have changed the way they look at IP. No longer just an expense, they now see IP as an asset and an investment for the future growth of their organisations.

This is what we live for at Yusarn Audrey, and what makes us excited and passionate about our work: igniting possibilities for our clients using IP.

Our clients: Over the years, the firm has successfully counselled and implemented IP strategies for local and international small and medium enterprises, multinational corporations, universities and government agencies.  A list of our clients is available upon enquiry.
