VO Patents & Trademarks

VO Patents & Trademarks is a firm of more than 60 patent attorneys, trademark attorneys and attorneys at law, backed by 140 qualified and experienced support staff. It is located in the Netherlands, Belgium and Germany with nine offices, including in The Hague and Munich. VO is the largest and leading IP firm in the Netherlands and among the top 10 major European firms. Serving our clients worldwide since 1916, we support 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

Our 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 are entitled to represent clients before the 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 have also actively participated in the realisation 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, we have an extensive referral network throughout Europe. For instance, in complex cases and cross-border litigation, we can form a team of different specialists from different firms.

How VO works

It is our 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. Our schedule of charges is based on a simplified costing system. For standard agency services relating to the 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 our clients are universities and research institutions. VO also regularly works with numerous law firms and patent attorneys worldwide in litigation.

Close to the action

Our main offices in The Hague and Munich are located close to the EPO. Therefore interviews and oral proceedings in connection with European patent applications examined in both cities can be handled efficiently. Also the court in The Hague, where all Dutch litigation in patent disputes is centralised, and the Benelux Office for Intellectual Property are in close proximity. Moreover, located in Munich are 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, deciding on nullity appeal proceedings, is easily reachable from Munich.

VO is ideally placed to help clients worldwide to protect and activate their intellectual property. We have the expertise to represent their IP interests on a European and a global basis. Further, we help bring companies together to make and sell third-party products under licence.
