Michael Ford

Senior Associate

Michael is a senior associate in the firm and co-leader of the Materials team. With a first-class MEng and a DPhil in Materials Science from the University of Oxford, he works with patent applications across the whole spectrum of materials. He has particular experience in drafting and prosecuting applications relating to metals and alloys, minerals, electrochromics, semiconductor device fabrication and fibre-reinforced composites, and works with SMEs, universities and multinationals. He also advises on freedom-to-operate and has experience of EPO opposition proceedings. Michael has a special interest in the use of computer modelling in the development of new materials and carried out research in this area at the University of Oxford, the Ruhr-Universität Bochum and the University of California, Santa Barbara.

Chloe Farrar


Chloe is a trainee patent attorney in the firm. She has a first-class MEng in Materials Science from the University of Oxford, in which she completed a research project focused on measuring the mechanical properties of ceramic matrix composites for nuclear power applications. As part of her degree, she studied the mechanical, electronic and optical properties of materials, including polymers, composites and semiconductors. During her time at HLK, Chloe has assisted in drafting and prosecuting applications involving composites, semiconductors and nanocrystalline materials, in fields ranging from aerospace and safety equipment to packaging and consumer goods.

Iain Robertson


Iain is a patent attorney in the firm. He has a Materials Science MSci degree from the University of St Andrews. It covered a range of topics, with a focus on ceramics and material structure characterisation. He has an interest in renewable energy, having done a research project on materials for rechargeable batteries. His degree also included a year working at EMPA, the Swiss Federal Laboratories for Materials Science and Technology, studying materials for solid oxide fuel cells. His PhD, also from the University of St Andrews, was in polymer solar cells, and it included a visit to the synchrotron at Stanford University to obtain polymer XRD data.

Joanne Addison

Senior Associate

Jo is a senior associate in the firm. Having an MSci in physical chemistry with research involving aluminosilicates, Jo works on a wide range of materials technologies. She works with SMEs, start-ups, universities and multinationals and has particular experience in drafting and prosecuting applications relating to functionalized fabrics, fiber-reinforced composites, batteries, diamond technologies, fuel cells and semiconductor device fabrication. Jo advises on all stages of the life cycle of a patent, from the initial drafting and examination of patent applications to post-grant validity challenges such as EPO oppositions. She also advises on freedom-to-operate and infringement issues.

Luke Dent


Luke is a trainee patent attorney in the firm. He graduated with a First in MEng Materials Science from the University of Oxford, where his master’s thesis on a novel method of ceramics sintering earned him a nomination for a national award. Luke has experience in industrial research, including the manufacture and characterisation of synthetic diamonds, and the degradation of nuclear steels. Luke has worked on drafting and prosecuting patent applications across a broad range of materials technologies, including graphene-enhanced materials, spintronic sensor devices, carbon-carbon composites, polymer packaging processes, and nuclear fusion technologies.

Magnus Johnston


Magnus is a partner in the firm. He works with many multinational corporations, including major energy companies, large steel producers, smart glass manufacturers and speciality minerals producers, all of whom value Magnus’ years of experience in the patent profession and his deep knowledge of their technologies. He has a BSc in Chemistry with New Materials Technology and a PhD in the synthesis of novel acentric open-framework crystalline materials containing transition metals. Magnus has a considerable case load of European oppositions and appeals, helping clients defend key patents in their portfolio and also helping them challenge the validity of competitors’ patents.

Stephan Schultes

Senior Associate

Stephan is a senior associate in the firm, where his PhD and industry research experiences into the thin film properties of a range of inorganic and organic semiconductor materials have proven invaluable in understanding the technologies of clients working in areas such as photovoltaics, data and energy storage, semiconductor manufacturing and sensors. He provides practical advice on all aspects of patent and other IP rights, from developing an initial IP strategy through to post-grant proceedings. He also has extensive experience advising on validity and infringement matters.

Nina Szamocki-Hoffman

Senior Associate

Nina is a senior associate in the firm, with a particular focus on materials with mechanical applications. She has experience drafting and prosecuting patent applications relating especially to composite materials such as fibre-reinforced composites and to methods of manufacturing with specific materials. She works with businesses of all sizes including start-ups, SMEs and multinationals, and her secondment with an in-house team of a multi-national corporation together with her MBA degree gives her a special insight into the challenges faced by in-house counsel and commercial drivers which impact decision making.

Greg Sharp (né Dykes)

Senior Associate

Greg is a senior associate in the firm. Having obtained a Masters in Mechanical Engineering, he works with patents relating to the engineering aspects and practical applications of materials. He has significant experience in drafting and prosecuting UK and European patent applications in these fields, along with expertise in the opposition and defence of granted patents before the EPO and UK IPO. Greg has a particular interest in the design and applications of composite materials, having focussed one of his major university projects on the use of fibre-reinforced plastics in dynamic structures and the effects of differing fibre orientation on their behaviour.
