Richard Clegg

Richard is a member of our life sciences patent team and has particular experience in the biotechnology and pharmaceutical sectors.   He has a diverse patent practise, working closely with clients in the UK, Europe and Singapore to prepare patent applications and prosecute them to grant on a global basis.  He also works with many US clients to obtain European patents before the EPO and defend them in EPO opposition/appeal proceedings.

Since 2003, Richard has been heavily involved in obtaining European patents for aptamer (SELEX) technology and succeeded in obtaining grant of the very first aptamer patents in Europe.

Richard also has considerable involvement with start-up and spin out companies, including transition of patent portfolios from technology transfer into nascent companies. In addition to patent prosecution, this often involves generating and implementing an ongoing freedom to operate strategy for the company and conducting IP due diligence for the purpose of helping the company raise investment. Richard has provided in-house support to some SME clients, spending time in the R&D department to spot inventions and generate new patent applications.

Richard has particular technical experience in:

  • oligonucleotide technology encompassing new compositions, therapeutics, diagnostics and novel chemistry
  • virology, e.g. herpes simplex virus technology
  • complex sugars and polysaccharides, such as heparan sulphates, and their use in regenerative medicine
  • diagnostics, including companion diagnostic methods and novel diagnostic assays, chips and test strips for use in personalised medicine
  • stem cell technology, including culture techniques and generation of therapeutic quality and quantity stem cells for use in regenerative medicine
  • novel peptides, including generation and selection of T cell epitopes for use in therapy
  • novel antibodies
  • oncology
  • inhaled therapeutics

MIP Research commented “Richard Clegg is another person clients find impressive.  One client says “I would say he ticks a lot of boxes”. He is available when you need him, he is able, he knows his stuff and he knows his detail.  He is capable of digging in hard.””  Richard is also acknowledged as being ‘technically strong and well-prepared‘ – The Legal 500 (2013).

Richard is a regular visitor to the USA, China and Singapore.  Richard has been visiting China since 2006 and has developed a strong network of IP contacts in China who can provide valuable assistance to clients interested in obtaining or enforcing IP rights in China.
