Partner, Patent Attorney London
Profile of Catherine Keetch

With nearly 15 years’ experience in private practice, it’s great to be part of such a dedicated, expert team. I focus on chemical and biochemical subject matter, and get great satisfaction from helping my clients protect and launch exciting new products.

As my practice has evolved, I’ve gained extensive experience and a broad client base, from individual inventors through to multinationals. I especially enjoy working on the wide range of cases this brings, including patent drafting and prosecution, as well as European Patent Office opposition and appeal proceedings.

My expertise covers a range of chemical and biochemical subject matter, in particular, engine oils, lubricants, petrol additives, ink technology, food chemistry, nutrition, oral and personal care products, polymer chemistry, analytical chemistry (particularly mass spectrometry), proteomics, protein chemistry, pharmaceuticals, medical devices and diagnostics.

I have signed the IP Inclusive Senior Leaders' Pledge to demonstrate my personal commitment to improving diversity and inclusion (D&I) in our firm.
