IAM Patent 1000:

2020: “The team at Slingsby Partners lives and breathes original patent drafting, and demonstrates particular strength in electronic engineering and telecoms – areas in which many members have industry experience. Several have also chalked up stints in the mechanical engineering, aerospace and automotive spaces; but whatever the technology, the firm can handle the brief. Its client-centric approach earns it many fans: “Slingsby feels more like an extension of our business, rather than an external supplier, such is its knowledge of our products, processes and people. The team is exceptionally impressive technically and has evident enthusiasm for its work and for the success of our company.” Namesake Philip Slingsby’s 30-year career includes a decade spent in-house at Nokia tackling licensing negotiations for SEPs – experience which informs his practice to this day; his remit also includes drafting software patents and advising on litigation involving US-based patents. Fellow partner David King is likewise skilled at assisting European companies with US litigation and files watertight applications in areas as diverse as electronics, automotive and software. Another software maven is Paul Roberts, who provides incisive guidance on the development of portfolios in the hot area of machine learning.”

2019: ""Slingsby Partners is a prosecution boutique whose sole focus is on patents. Superb at drafting bespoke applications to fit any engineering, electronic or physical sciences invention, it eschews a ‘cookie-cutter’ approach in favour of targeted, commercially sensitive advice. As one client says: “The firm’s technical understanding is extremely high, and it is extremely efficient – the best patent attorney firm I have worked with in my career.” Name partner and founder Philip Slingsby established it in 2013 and has built it into the outfit it is today. He is “not only excellent in his execution, but a valuable strategic partner: a scientist first and a lawyer second”. Prosecution partner David King is a software, electronics and mechanical maven whose advice is “invaluable”, to the point where he is essentially trusted as an “in-house adviser” to his clients."

2017: "Rights holders seeking on-point, easily implementable advice should look no further than engineering, electronics and physical sciences specialist Slingsby Partners. Fastidious drafters, its tech-savvy practitioners strive for first-time perfection and put clients’ needs front and centre on all briefs. The set continues to thrive – it moved into new offices in 2016 – and has expanded its advisory operations of late. Founder Philip Slingsby is “highly respected by everyone he works with”; clients have “complete trust in his unparalleled level of technical intellect and commercial understanding”. Telecommunications giant Huawei and multinational computer chip designer Imagination Technologies are among his roster of innovative clients."

2016: "'Slingsby Partners provides an unrivalled level of technical expertise and understanding.  The main differentiator is its willingness to get involved in the fine detail and technical aspects of patent-related matters.  The advice provided is of the highest standard, as well as being pragmatic and commerically relevant.'  The Chancery Lane-based IP outfit maintains a prodigious workload and a loyal following - in no small part thanks to the fame of name partner Philip Slingsby.  'His approach is always through, but also creative and commerical, particularly when it comes to the defensive strategies being deployed by his clients.'  Active in the profession since the early 1990s, he has now successfully represented clients in over 50 opposition and appeal hearings before the EPO."

2015: "'The entire team at Slingsby provides a wonderful level of service. Its practitioners have a detailed understanding of clients’ products and the sectors within which they operate, so they never fail to turn out high-quality patent applications. The group copes well with the most demanding in-house teams and easily adapts when asked to follow new procedures.' The small size of the team belies the number of different technical areas that it can adroitly cover. Philip Slingsby sets the tone: 'With his experience and knowledge, he is a true asset to have on your side. He’s very quick to understand difficult technical issues, and moreover, his advice is resolutely commercial.' "

2014: "IAM Patent 1000 newcomer Slingsby Partners has rapidly gained momentum since its creation early in 2013, with satisfied patrons lining up to sing its praises: 'The people there have proved to be flexible and reliable and can move quickly when required at a moment’s notice. They have a great knowledge of our business and form close working relations with our inventors. You can rely on them to give insightful, valuable advice exactly when you need it.' The creative group shines on non-contentious affairs, but its horizons are broad – it aligns itself closely with in-house counsel to meet all of their protection and defence and enforcement needs. The compact team is blessed with a number of skilled attorneys, but first among them is Philip Slingsby. 'Philips’s experience and knowledge of his client’s technology and operating environment is remarkable. He is world class and you can’t help but recommend him to others.'"
