About me

Pieter’s practice was for years focused on, and continues to include, the drafting of patent specifications and the filing and prosecution of patent applications both locally and abroad.

In this field of legal practice, Pieter has had extensive exposure to and experience in the prosecution practices of the patent offices of most major foreign jurisdictions, including the United States Patent Office, the European Patent Office, the Chinese Patent Office, the Japanese Patent Office, the Australian Patent Office, etc. Pieter also deals with the preparation and filing of design applications.

More recently, over the course of the past 5 years, the Pieter’s practice has developed into other areas of work, including assisting clients with their intellectual property protection, management, and risk-identification strategies, conducting intellectual property due diligence investigations, and advising clients on technology transfer, licensing, and technology development transactions.

Pieter has a strong focus on providing holistic and comprehensive, business-focused advice to clients, mindful of their short, medium, and long-term interests. In this regard, Pieter often leverages the multidisciplinary diversity of Adams & Adams’s practice by involving colleagues practicing commercial law in intellectual property matters.
