Arnie is involved in both contentious and non-contentious patent work in the fields of pharmaceutical, medicinal, industrial, food and organic chemistry, with particular technical expertise in small molecule pharmaceutical chemistry, secondary formulation of pharmaceutical products, electronic materials, and industrial formulation chemistry.

Main specialisms
Arnie’s legal specialism is in European contentious procedures, particularly the European opposition procedure. His areas of technical specialism are mainly in the pharmaceutical, chemical and material science fields. These specifically include:

• NCEs (New Chemical Entities)
• pharmaceutical parenteral and inhalable drug technology
• semiconductor materials
• human and animal food, particularly sweetener technology
• detergent, dye and bleach technology
• battery materials
• carbon speciality materials
• refrigerants

Arnie works with a diverse range of clients including start-ups, SMEs, large multinational companies, and other IP practices around the world, and he particularly enjoys the direct interaction with in-house patent departments, inventors, and patent attorneys from other national jurisdictions.

Notable clients include some of the largest pharmaceutical and FMCG companies in the world, where Arnie handles opposition and appeal work, acting for both patentees and opponents in more or less equal measure.

Arnie is a cricket and wine fanatic, and is prepared to travel the Earth to find both. When indulging in neither of these, Arnie also enjoys rugby (watching rather than playing these days) and the company of his family – obviously not in that order.
