PATMA: Patent attorneys Tier 2

Already known for the depth of its telecoms, electronics and mechanical engineering practice, EIP strengthened its life sciences and healthcare business with the addition of Gareth Probert and Monika Rai, from HGF Limited and Mathys & Squire LLP, respectively. In Colin Lobban, a former division head of IP at Dyson, the group gained an experienced engineering attorney. The practice predominantly undertakes direct work, drawing on its international offices in Denver and Düsseldorf and its combined offering of patent, trade mark and design specialists and IP litigators to assist clients with the full range of matters. In addition to its comprehensive prosecution offering, including an increasingly busy opposition and appeals practice, the team also frequently acts in an advisory role in strategic projects, such as portfolio analyses and due diligence, and is experienced in accompanying high-stakes patent litigation. The London-based Jerome Spaargaren and Heather McCann and Bath-based Matt Lawman lead the practice.


‘Darren Smyth is the best patent attorney that I have ever had the pleasure to work with. He is extremely clever and knowledgeable, as well as being down-to-earth and approachable. The creme de la creme of patent attorneys in the UK.’

‘The team are highly professional and devoted to the work they do. They have a very diverse range of professional and personal interests, which gives the whole team an incredible depth and breadth of perspectives, which cannot be underestimated when you are talking about the law dealing with the edge of science and technology.’

‘The team has been responsive and effective in handling our European patent matters.’

‘Their IP attorneys are very knowledgeable when it comes to technology and quick to learn new things.’

‘They have very good IT/comms/physics/system base knowledge that can be readily translated into understanding and drafting patents with a good sense of what is and is not patentable. Open and collaborative.’

‘Chris Price is a highly experienced patent attorney who is easy to work with, clear in his communications and pragmatic in how to manage the patenting process on a worldwide basis.’

‘Their patent prosecution and litigation teams take an integrated approach in pre-suit portfolio building and enforcement matters, not siloed like many firms. Good knowledge of integrated global patent strategy.’

‘Precise analysis and pragmatic recommendations.’

‘Jerome Spaargaren is readily available and always provides useful insight into complex matters.’

Intellectual property: patents (contentious and non-contentious) Tier 3

EIP’s patent litigation experts are market leaders in the field of FRAND litigation in the telecoms sector, having spearheaded numerous high-profile trials in the Supreme Court and Patents Court under the guidance of Robert Lundie Smith, Matthew Jones, Andrew Sharples and 'totemic strategistGary Moss, who heads the practice. According to one client the firm has 'virtually cornered the market in acting for telecoms patent holders seeking FRAND royalties for their patent portfolios'. New joiner Kathleen Fox Murphy from Browne Jacobson LLP further enhances this expertise, while also reinforcing the team’s expertise in the pharmaceuticals and emerging technologies sectors.

Practice head(s):


EIP has built a strong reputation as a market-leader acting for patentees in patent licensing disputes in the telecoms arena, in particular where a patent portfolio is sought to be licensed on a FRAND basis. EIP comprises both solicitors and patent attorneys, and the mix of the two is a considerable strength since the patent attorneys have deep expertise in telecoms technology, so they have vital input into the technical aspects of the cases. On the solicitor front, considerable expertise of this sort of dispute has now been amassed.

Relatively small but highly effective team of IP litigators.

EIP have virtually cornered the market in acting for telecoms patent holders seeking FRAND royalties for their patent portfolio’

Very commercially focused, with wide strategic and tactical experience, and a huge depth of highly skilled technical knowledge.

Rob Lundie-Smith is a stand-out partner. He is extremely hardworking, has a strong grasp of the issues and really thinks around the problems. He is also unfailingly good-humoured, courteous and a pleasure to work with, even in times of great stress.

Gary Moss, as the senior partner, has an encyclopaedic knowledge of FRAND disputes, and is the tactical powerhouse behind EIP. 

Gary Moss is a totemic strategist, with unparalleled experience in large-scale telecoms litigation. There is not a trick in the book that he doesn’t know, of which there are few that he didn’t create himself.
