Dr Richard Tatham

Senior Patent Attorney

Richard is a Chartered UK and European Patent Attorney whose practice spans such diverse areas as cryptography (classical and quantum) and digital security, telecommunications, quantum computing, quantum-based sensors, machine learning and artificial intelligence, blockchain technology and cryptocurrencies, digital imaging, bioinformatics and medical devices. Richard has a PhD in Theoretical Physics from the University of St Andrews.

Richard has advised research institutions and companies of all sizes, from innovative start-ups to large multinationals, and in sectors including telecommunications, software, security, medical services, and financial services to name but a few. For start-ups and SMEs, Richard has helped to define and develop bespoke intellectual property strategies in order to assist clients in best practice management of their patents, trade secrets and designs.

Richard has amassed experience in handling IP matters across a wide range of technologies, although has particularly focussed on the areas of physics, electronics, and software. He has particular experience drafting and prosecuting patent applications concerning:

  • Quantum technologies, including quantum computing, quantum cryptography, quantum algorithms and quantum metrology.
  • Machine learning, particularly using neural networks and/or random forests
  • Blockchain technologies, including both novel blockchain architectures and novel blockchain implementations with smart contracts
  • Telecommunications, including standards essential patents, user interfaces, network communications and messaging protocols
  • Cryptography, including position verification protocols and public key protocols such as elliptic curve cryptography
  • Medical devices, particularly in relation to blood analyte sensors and radiopharmaceutical imaging.

Richard is a true philomath, logophile and puzzle enthusiast who takes a keen interest in cutting edge technologies, particularly if there is interesting mathematics or physics behind the curtain. As such, Richard is well suited for the technical disputes and logomachies required to obtain and maintain an effective intellectual property portfolio.

Richard completed a PhD in Theoretical Physics at the University of St Andrews after graduating with an MSci in Natural Sciences from Durham University (with a focus on physics, mathematics and philosophy). Richard’s PhD studies concentrated primarily on quantum information theory, and in particular on non-classical correlations in and beyond quantum entanglement in bipartite continuous variable systems. He has published, and continues to occasionally publish, academic papers relating to quantum entanglement, quantum discord and quantum cryptography. Richard also studied the theory of transformation optics using metamaterials. He also speaks conversational Russian.
