De Vries & Metman

De Vries & Metman (DVME) is a Dutch patent attorney firm which is internationally recognised for its high-quality patent services. DVME has offices in Amsterdam, Arnhem and Eindhoven. The firm prosecutes and litigates patent rights for its national and international clients, which range from global players to small and medium-sized companies and start-ups that share a drive for innovation and a passion for technology.

Most of our attorneys previously worked in industry, patent offices or law firms. As such, we understand clients’ needs and provide practical and commercially relevant advice. We work proactively and are committed both to building business-relevant patent portfolios for clients and helping to defend clients against the patents of others by, for example, filing oppositions and appeals or advising on circumvention routes.

We advise a range of clients from start-ups at the team level to internationally operating companies at the board room level on implementing a patent policy that fits the overall strategy of the business and creating patent awareness throughout the organisation. To that end, we liaise with other experts – for example, tax advisers on using patents as a business tool in international tax schemes.

DVME delivers high-quality hands-on services in patent matters in all fields of technology.

Our chemistry and life sciences group handles inventions in all areas of chemistry and chemical technology, biotechnology and molecular biology. For example, we are involved in work relating to coatings, adhesives and sealants; biodegradable and renewable polymers; pharmaceuticals, including vaccines, antibodies and drug discovery and formulation technology; fermentation processes and products; food products, food additives and neutraceuticals; and personal and household care products.

Our information and communications technology group handles computer-implemented inventions and electronics. For example, we are involved in work relating to telecoms; multimedia and coding standards; wireless sensors and sensor networks imaging and display techniques; algorithms; graphical user interfaces; the Internet of Things; cryptography; artificial intelligence, including deep learning; augmented and virtual reality technology; blockchain; secure multiparty computations; fintech; photonics; semiconductor technology; and green technologies including solar and smart metering.

Our engineer group handles inventions in all areas of mechanical and civil engineering. For example, we are involved in work relating to naval construction and offshore technology; energy technologies (eg, wind and solar); greenhouses and horticultural equipment; chemical and pharmaceutical process equipment and technology; food industry; packaging technology and materials; consumer products; medical equipment and devices; light, optics and photonics; and semiconductor manufacturing technology.

Beside patent prosecution work, we have a strong expertise in technically and legally complex patent litigation cases. Our attorneys are therefore frequently asked to assist law firms in patent litigation proceedings. We have been involved in many high-profile international patent disputes. Further services include freedom-to-operate analyses, product clearances, due diligence work, assisting clients in domestic and foreign patent issues and licensing matters.

We actively participate in different IP organisations and educational bodies, including the Dutch Institute of Patent Attorneys, the Dutch Bar Association, the Institute of Professional Representatives before the EPO, the International Association for the Protection of Intellectual Property Dutch Group, the Examination Committee of the European Qualifying Exam, Delft University of Technology and Leiden University.

DVME won the Managing Intellectual Property award for patent prosecution in the Netherlands in 2011, 2012 and 2018, and has been ranked as a top-tier patent prosecution firm in the Netherlands since 2011. It has also been highly recommended as a patent prosecution firm in the IAM Patent 1000 since 2014.
