Overseas Associates

Why use Madderns?

Madderns has more than 50 years of experience working with overseas associates in relation to their clients’ patents, trade marks and designs requirements both in Australia, and more recently in New Zealand as well.

Our firm has the breadth and experience to ensure you feel confident in entrusting your clients’ cases.

Our patent attorneys’ expertise covers the full range of technologies from telecommunications and engineering, to chemistry, pharmaceuticals and life sciences. Many of our attorneys have PhDs or other higher degrees in their field of technology, as well as many years of industrial experience.

Madderns also has a specialist team of experienced trade mark attorneys who practice exclusively in trade marks. All of the attorneys in the team have previously practised as intellectual property / commercial lawyers and are well qualified to handle high level prosecution work, trade mark oppositions and non-use cancellation proceedings.

Many of our attorneys have also been practising in IP for more than 20 years, and some for more than 30 years. For more information about our team and their specialties, click here.


We have a well-earned reputation for being responsive and helpful and are happy to answer any questions that you or your clients may have on any aspect of Australian and New Zealand IP practice. Simply send us an email or call us.

Tailored Approach

We understand that different firms and clients require specific approaches in communication and billing styles. We are happy to discuss your requirements and tailor our communications accordingly. Some of our clients prefer activity based billing while others prefer a single bill once per month. Some clients prefer billing based on hourly rates while others prefer elements of a fixed-fee arrangement. Some prefer a mix of billing styles. Please contact us to discuss your requirements.

Regional Hub

Thanks to our many years of experience in the Asia Pacific, we have developed close relationships with associates in this region and a comprehensive understanding of the various IP systems that operate in countries within the region. As such, some of our overseas associates use us as a central hub to assist them in filing and prosecuting their IP cases in countries where communications are more difficult or the IP system is unfamiliar to them. Using Madderns to file and prosecute the same matter in multiple jurisdictions in the Asia Pacific can also, in some cases, provide efficiencies in both communications and costs.

Litigation Support

Under Australian practice, patent and trade mark attorney firms typically do not run IP litigation cases directly. Madderns has significant experience in providing litigation support to these proceedings. Madderns can provide a centralised coordinating role and also assist with identifying an appropriate team of external solicitors and barristers to represent you in the Australian Courts.

Independently and privately owned

Madderns is a privately-owned and incorporated firm under the day to day management of a Managing Partner who reports to a board of Directors. Each of our Directors is an attorney who works within the firm.
