Legal 500:

"Slingsby Partners LLP has an 'exceptional' practice, whose main differentiator is its 'level of understanding and detailed consideration'. Managing partner Philip Slingsby heads the team and advised Cambridge Medical Robotics on the patent portfolio behind its new surgical robot. Other key figures include Paul Roberts, who is is an expert in drafting and prosecution in the life sciences sector, and Rosalind Fenwick, who has a similar skill set but focuses on the electronics sector. Also recommended are David King, who has 'a highly organised and intellectual grasp of all technical matters', and Sarah Binham, who has been drafting patents for Huawei."

IP Stars:

"Slingsby Partners specialises in patent drafting and prosecution. The firm has grown since it was founded in 2013 by patent star Philip Slingsby. A client says: “Slingsby Partners provides an unparalleled level of technical knowledge and ability.” Its European patent attorneys are recognised for their expertise in engineering, telecoms and electronics. Slingsby leads the practice alongside Paul Roberts and Rosalind Fenwick. Slingsby is commended by a number of clients. “Philip is exceptionally bright and capable of understanding the technical intricacies of the projects our company works on,” says one. Other notable senior patent attorneys are Sarah Binham, Anne Campbell and David King, who was promoted to partner in 2017. “David is an excellent IP practitioner with an ability to understand and develop complex technologies with our engineering teams,” a client comments. Another adds: “David King is very knowledgeable in patent law and able to learn complex inventions rapidly in order to ensure that they are explained and protected.”

"The senior attorneys are supported by a team of associates. Arnie Francis, Stephen Turner and Nikki Davy, who is qualified as a lawyer and patent attorney, are the rising stars to watch. Davy is commended by a client: “Nikki had to step in part way through and did so flawlessly despite our technology being subtle and complex. Everything was handled very well.” A small technology company picks out what they particularly like about the team: “What we like is their ability to deal with our naivety in the sense that we are a very young company and have given Slingsby very limited instruction and information, but they have been able to make something useful from it.” Case studies show that the firm advises well-known companies on patent infringement and invalidity, portfolio management and office proceedings. Notable clients include Imagination Technologies, Idex ASA and Huawei."
