Novo Nordisk A/S v. DSM NV [2000] EWHC Patents 34 (21st December, 2000)
The patent was found invalid for obviousness over common general knowledge and the Ullah 1988 paper, as the use of Flat Bed IEF for purification of phytase did not constitute an inventive step beyond what was already known or obvious to the skilled person at the priority date. The claims were also found insufficient as the specification did not enable the invention to be performed across the full width of the claims without undue burden or invention. No added matter was found beyond the application as filed.
