JUVE Comment

The market-leading Dutch patent litigation team at IP boutique Hoyng ROKH Monegier continues to impress competitors and clients with its retention of high-profile cases across a broad technical spectrum. “Good quality work; we worked with a number of their patent attorneys and lawyers,” a client says.

The boutique also boasts a strong patent attorney team running an impressive patent prosecution practice. Hoyng ROKH’s patent attorneys are highly experienced in litigation. Up-and-coming Andrew Lin, for example, is involved in various UPC proceedings concerning mobile communications, including for Acer. Most cases concern international disputes where the Dutch team works closely with its German, Belgian and French counterparts. It continues to impress with its dominance in high-profile cases, particularly in the life sciences sector. A Dutch team led by Theo Blomme works alongside a German team for BioNTech in various cases against Moderna before national courts, and for GSK at the UPC. At national level, partners such as Blomme and Peter van Schijndel remain active in ongoing cases for originator drug companies including Johnson & Johnson regarding Stelara, Regeneron concerning Eylea, and Astellas over Xtandi. New instructions from Newron and Zambon regarding Parkinson’s drug Xadago, and from Takeda concerning Entyvio, underscore the team’s strong standing among pharmaceutical innovators.

The Dutch team recently underwent a generational transition, marked by the departure of star litigator Bart van den Broek to the UPC and the promotion of a new partner. Roeland Grijpink is increasingly stepping into the spotlight, compensating for van den Broek’s departure. He is leading important SEP and UPC cases for technology giants such as Philips and Acer. The firm’s strength at the new court is further demonstrated by wins for Orbisk and Washtower, as well as its involvement in numerous other UPC proceedings.
