VO Patents & Trademarks

VO Patents & Trademarks is a specialist firm of more than 60 patent attorneys, trademark attorneys and attorneys at law, backed by 140 qualified and experienced support staff. It has nine offices across the Netherlands, Belgium and Germany, including in The Hague and Munich. VO is the largest and leading IP firm in the Netherlands and among the top 10 European IP firms. Serving its clients worldwide since 1916, it supports them in maximising the value of their intellectual property.

Over the years, the firm’s consistent growth in volume and client base has led to an expansion of its workforce and office network. Indeed, VO is a European firm with strong Dutch roots, combining native entrepreneurial attitude with a strong drive to explore new territories.

Experienced professionals

VO’s professionals include European, Dutch, Belgian and German patent attorneys and a US patent agent, as well as European and Benelux trademark and design attorneys, and attorneys at law. European patent attorneys can represent clients before the European Patent Office (EPO), which has a branch office in The Hague.

Professional pride

Rigorous training programmes, both in-house and externally, ensure that both attorneys and back office staff are qualified to the highest standards. This is illustrated by the excellent results of VO candidates at the European patent attorney qualifying exam. Partners and associates of the firm are active in professional organisations, both nationally and internationally, in governmental committees, and in education and professional training. They also actively participated in the establishment of the European Patent Convention.

Your full-service IP partner

As a full-service firm, VO also has in-house specialists providing top-quality search, annuity and translation services. In addition, it has an extensive referral network throughout Europe. This means that, for instance, in complex cases and cross-border litigation it can form a team of different specialists from different firms.

How VO works

It is the firm’s standard procedure to draw up a plan of approach based on each client’s specific needs. The best IP strategies are chosen together with the client. Its schedule of charges is based on a simplified costing system. For standard agency services relating to patent filing and granting procedures, an all-in amount is charged. This is simple, predictable and cost-effective.


The firm fosters strong relationships with its extensive national and international client base, covering all sectors of industry and all sizes – from multinationals to small and medium-sized companies, including spin-offs. Among its clients are universities and research institutions. VO also regularly works with numerous law firms and patent attorneys worldwide in litigation.

Close to the action

VO’s main offices in The Hague and Munich are located close to the EPO, making attending interviews and oral proceedings in connection with European patent applications examined in both cities more efficient. The court in The Hague, which hears all Dutch patent disputes, and the Benelux Office for Intellectual Property are also in close proximity. Similarly, Munich is home not only to the EPO but also to the German Patent and Trademark Office, the German Patent Court and two of 13 German district courts dealing with IP matters. In addition, the German Federal Supreme Court, which decides on nullity appeal proceedings, is easily reachable from Munich.

VO is ideally placed to help clients worldwide protect and exploit their intellectual property. It has the expertise to represent their IP interests on a European and a global basis. VO also helps bring companies together to make and sell third-party products under licence.
