The Patent 1000 focuses exclusively on patent practice and has firmly established itself as the definitive 'go-to' resource for those seeking world-class legal patent expertise.

Silver - Firms: prosecution

The Belgian arm of Dutch heavyweight NLO is dedicated to innovation, as evidenced by its confident collaboration with inventors in virtually every scientific field. The electronics sector is a strong suit for the group, but entities of all shapes and sizes feel secure in instructing this team of resourceful professionals, whose wealth of expertise in European patent prosecution makes them stand out on the market.

Gold - Firms: prosecution

“When it comes to quality, NLO is at the top of the game” and thanks to the depth of its bench and breadth of its technical versatility, the group has become the first port of call for both small inventors and big corporations looking to make their mark in Europe. For mechanical and medical device clients, Paul Clarkson and Maarten Ketelaars are the names to note. As a former examiner at the EPO, Clarkson has a distinct edge when handling opposition proceedings – at the moment, he is representing Danone in over 20. From early patentability advice to drafting, prosecution and portfolio management, Ketelaars is there for his patrons. Physicist Hans Bottema relishes working at the cutting edge of technology and leverages his in-house experience to effectively support inventors with both legal and business needs. On the electronics and telecommunications front, Hans Hutter is the go-to for matters concerning SEPs. Recently he has been assisting Nokia in its infringement and nullity actions in the field of ADSL technology. For those in the food and nutrition industries, David Bot is excellent at devising practical IP strategies that not only align with a company’s commercial strategy, but further its business goals too. On the life sciences side, Bart SwinkelsArthur MeekelRené van Duijvenbode and Mari Korsten are shining stars. A genomics specialist, Swinkels is a superb choice for innovators looking to launch their products onto the market, while chemists Meekel and van Duijvenbode put in assured performances at the EPO. Trusted counsel for the likes of Amgen and Pfizer, “Korsten is an excellent patent attorney and a very good strategic partner who truly understands his clients’ business and industry needs”. Deftly traversing the contentious/non-contentious divide is Catherine Shultz, a US lawyer and European patent attorney who brings a global perspective to portfolio management. Burcu Sucuka, who joins the team from Turkey, marries her degree in cell biology with her legal nous to provide creative counsel that truly optimises her clients’ intellectual property.
