‘The team has an excellent technical understanding of our technology area, which is very niche and hard for most individuals to grasp. This makes the patent development process so much easier. During the process of trying to get the invention down on paper, the team are able to suggest areas of potential innovation or to point out common knowledge at a very early stage, saving time and money but at the same time potentially generating new commercial IP in the form of sub patents.’

‘Broad experience across the range of technologies that my company has exposure to.’

‘Extremely responsive and eager to understand my company’s needs. Flexible and accommodating when it comes to matching expectations regarding timing and budget.’

‘The Mathys & Squire team has made the entire process of the patent application an exceptional experience. We have received appropriate advice to enable us to gain better positioning. Their billing is also transparent and has shown good value for money compared to other firms we work with.’

‘Craig Titmus is an exceptional lawyer. He has read our the patent so carefully and thoughtfully that his work with the patent offices tends to result in our favour. He presents the commentary and issues with such clarity that we don’t need a legal interpreter to understand and respond to them. This saves a lot of time and fees. Besides being a really clever lawyer, Craig is a truly nice person. We hope to work with him for all of our IP and patents going forward.’

‘Showed great technological knowledge and effective support in prosecution in front of the EPO. Cost effective and very responsive.’

‘The diversity of patent concepts we bring forward in our field across a range of activities is always met by a team of experts with relevant expertise to draft patents quickly, enhance our concepts and provide assurance to our sponsors on the novelty and enforceability of our IP. We have always had priority for important filings. Advice to support our commercial partnerships and their strategic direction has always been generous and valuable.’

‘The individuals we work with in Mathys & Squire are all highly skilled, clear, driven and provide excellent service, especially under pressure. We would like to single out Chris Hamer, who has been exemplary. Chris is equally at home working with us on patent filings and advice one minute and the next advising CEOs and board members on the status of IP and influencing our commercial strategy. He is always available no matter what time of day.’

‘Mathys & Squire LLP really can’t do enough for you. If you want a firm that will go the extra mile and provide industry-leading client service then I would wholeheartedly recommend them. We have entrusted our most important patent portfolio to them and continue to be impressed by the diligent, professional and successful way they have managed the prosecution.’

‘Anna Gregson and Martin MacLean are accessible, knowledgeable and provide a really outstanding, can-do attitude.’

‘Approachable and friendly, which is a key factor. Very knowledgdable in all manners of managing, and applying for, IP. Very swift in their response time.’

‘Paul Cozens produces work of a consistently high quality and is very commercial. He is especially adept at dealing with software in the context of engineering.’

‘This is most certainly a unique practice. Their key strengths and capabilities are the uniformly very high standard of patent and trade mark work across the entire firm; very good communication skills; ability to obtain excellent results; and the exceptionally high level of honesty and trust. Their cost structure is very fair and they are nice people to do business with. Overall, this is an outstanding firm, and I cannot recommend it too highly.’

‘Craig Turner is an absolutely outstanding attorney. He has managed to obtain patent grants in the most difficult (and sometimes hopeless) cases. Craig is an excellent advocate in addition to his more usual, routine patent agent work. Finally, he always responds to written questions very quickly, and is always very happy to set up phone discussions and face-to-face meetings. In short: an attorney of the highest calibre.’

‘They are flexible to the needs of start-up companies.’

‘The team are innovative and creative in their responses on challenging issues in software and telecoms prosecution. They listen to feedback, work to understand the business goals, and then work to create a path to issuance with those elements at the front of their mind. Their success rate and the quality of the claims they obtain is consistently high – an excellent combination.’

‘Mike Jennings has the benefit of both a very creative approach to legal problem solving and an engagement in the patent community generally and with the EPO and UKIPO, which gives him the ability to understand and even help guide the offices towards appropriate solutions to their challenges while also giving his clients access to insights into the current law and its potential and likely developments.’

‘A highly professional, knowledgeable and kind team.’

‘Great attention to details. They advise businesses and draft patents with the commercial aspects in mind.’

‘The relatively young but highly experienced partnership at Greaves Brewster gives it a fresh and modern look and approach that is fairly unique in the market. Though they are known for their strong life sciences and chemistry expertise, in recent years they have expanded their team to include more expertise in engineering, physics and nanotechnology.’

‘What makes Greaves Brewster an attractive proposition for in-house counsel is their focus on client care, the fact that they are user friendly and pleasant to work with, their commercial awareness, and the fact that they are a fairly diverse team and that their clients span small start-ups to multinationals.’

‘Rachel Wallis is incredibly responsive with a razor-sharp focus. She provides excellent service with measured advice and strong commercial awareness. She is a key trusted adviser – I know that she will look out for the client.’

‘Professional but personal. Active in taking an interest in the portfolio and direction of the business. Accessible and engaged.’

‘Rachel Wallis is proactive and interested. She is prepared to make sure that all issues are addressed irrespective of impact on her personal time. Kate Hillis is informed and engaged.’

‘Greaves Brewster punches above its weight. Its partner-led team is user friendly and commercial and also shows great flexibility in how it works.’

‘Jakob Bumke, Rachel Wallis and Rhiannon Turner are all standouts at Greaves Brewster.’

‘David Spinner is fantastic. His ability to communicate complex concepts in simple terms shows a real understanding of the tech. He is clearly very bright, and understands the complexities of litigation as well as the pure patent prosecution and defense strategies, which makes life so much easier. He is a pleasure to work with.’

‘The direct one-to-one interaction and swift responses to any of my questions is one of the most outstanding things that comes to mind about the firm.’

‘They have built strong relationships with myself and other members of my office and academic teams, which allows them to really understand the key issues we face when patenting academic inventions.’

‘With all of the people we deal with at Adamson Jones, there is a feeling that they are working with us, rather than for us. Their commercial understanding is part of this, but also their willingness to make themselves available at short notice to discuss cases and issues. Simon Cooper deserves a special mention – his advice is always detailed, considered, relevant and clear.’
