Vereenigde Octrooibureaux – Netherlands 2021

JUVE Comment

Vereenigde Octrooibureaux is still the largest patent filing firm in the Netherlands in terms of patent attorney headcount. The firm also operates a small but strong practice for litigation on the patent attorney side, which, with two distinctive technical specialties – life sciences and mobile communications – conducts revocation suits and infringement proceedings. Numerous Dutch law firms consistently call on the firm for the latter.

V.O. excelled in one of the few new mobile communications cases in the Netherlands on the side of Google against Sonos regarding speaker technology. Both companies are fighting parallel proceedings in Germany. The firm also represents Assia in a dispute over DSL technology. Marco Box’s reputation for mobile communications cases is therefore strong. Despite the work for Google, V.O. has not landed as many new cases in this segment as market leader De Vries & Metman recently.

Like Arnold & Siedsma, AOMB and NLO, the V.O. patent attorneys enjoy a good name for life sciences patents. Until the settlement in 2021 they represented Eli Lilly in the Dutch proceedings concerning the cancer drug pemetrexed. Another notable originator company on the pharmaceutical research industry side is Novartis regarding chemotherapy drug Affinitor. In those cases the patent attorneys work beside external lawyers from Hogan Lovells and Freshfields.

But unlike AOMB and NLO, V.O.’s patent attorneys do not focus solely on life sciences and mobile communications. The firm boasts two of the leading individuals in the Dutch market for litigation concerning mechanics patents, Bernard Ledeboer and Leo Jessen. Only De Vries & Metman can currently rival the firm’s technical breadth.

Before the EPO, the V.O. patent attorneys can easily hold their own against UK and German patent filing firms in terms of technical breadth, headcount and the frequency with which they appear in EPO proceedings. V.O. is also the only Dutch firm with an established team of local patent attorneys in Germany.


Patent litigation conducted by patent attorneys regarding electronics, mechanical engineering and pharmaceuticals.

European strategy

V.O. has an unusually international setup. Like Arnold & Siedsma and NLO, the firm has Belgian offices in Leuven and Liège. It also has an office in Munich. With a further office in Regensburg, including two German patent attorneys, the firm advises the highly active biotech scene in Bavaria.

The offices in Amsterdam and Munich make V.O. well set for the UPC launch. V.O. could also benefit if the former London sections of the central division go to Amsterdam, given its pharma specialty. An office at the central division location would also make sense for V.O., like all large patent attorney firms from Germany and the UK, because of its strong focus on litigation.
