VO Patents & Trademarks

VO Patents & Trademarks (VO) helps clients worldwide to get the best out of their intellectual property. VO, established in 1916, is one of the biggest European patent attorney firms and is praised as a centre of excellence. In 2010, 2013, 2014, 2016 and 2017 the firm received the Netherlands Prosecution IP Firm of the Year Award from Managing Intellectual Property. Its attorneys are admitted to practise before the European Patent Office (EPO). Further, the firm has Dutch, Belgian and German patent and trademark attorneys who also regularly assist in international litigation cases.

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. In 2012 the firm opened offices in Regensburg and Leuven, thereby further consolidating its European position. The Regensburg office is its second office in Germany, the first being in Munich. In 2015 the firm opened an office in Amsterdam.

Experts in technology

Patents are VO’s core activity. The firm’s patent attorneys are renowned experts, assisting clients with patent prosecution, advising on IP protection and taking action against infringement. With more than 60 professionals, the firm covers the full range of chemistry, life sciences, engineering and software/ICT – from bioinformatics and semiconductor software to food, health technology and telecommunications. This expertise is combined with a keen sense of business, which enables VO to handle intellectual property from the client’s perspective.

In addition to patent attorneys, the team of trademark attorneys assists clients in matters concerning trademarks and designs – IP rights that are complementary to patents, but require an altogether different approach. Our attorneys at law are ready to provide legal support in complex civil and IP cases and are specialised in (for example) drafting licence agreements and handling restoration cases.

Extensive experience in international work

VO patent and trademark attorneys have ample international experience and are familiar with the requirements in different countries around the world. The firm has a long-standing global referral network and is accustomed to teaming up with specialists from law firms in complex cases and cross-border litigation.

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.
