Maiwald is ranked in Chambers Europe 2018 as a leading firm for patent prosecution, in particular for representing clients in opposition and appeal proceedings before the EPO, whilst also advising on patent application and portfolio management. According to Chambers, “The attorneys win praise for their confident demeanour in oral proceedings and their proactive attitude”. Chambers quotes a client saying: “They understand the technology quickly, are very skilled in handling oral proceedings before the EPO, and present arguments really well. All the attorneys are very service-minded and usually a step ahead, suggesting things we want to do before we even ask for them.” According to Chambers, others also point out the attorneys' foresight, stating: “They stand out because they develop and execute strategies well in advance.” As a work highlight, the representation of Radiometer in several contentious proceedings is mentioned. Dr Eva Ehlich and Marco Stief are considered key contacts for clients.
