The claim patented sought to protect a genetic molecule rather than a whole mouse namely that the molecule would, if inserted into a suitable host cell, cause the cell to make antigens of the Hepatitis B virus. A recombinant method of making the antigens of a hepatitis virus was patented with a priority date of 22 December 1978 but was conceded to have been obvious by 21 December 1979.
Held: The claim for a DNA patent was too broad; no new principle was shown, and other means were available of achieving the technical effect claimed. The question of whether an invention was obvious should be treated with appropriate respect by an appellate court, and specific findings of fact, even by the most meticulous judge, are inherently an incomplete statement of the impression which was made upon him by the primary evidence. Where the application of a legal standard such as negligence or obviousness involves no question of principle but is simply a matter of degree, an appellate court should be very cautious in differing from the judge’s evaluation. Disclosure must enable the invention to be performed to the full extent of the monopoly claimed.
Lord Hoffmann discussed a court of appeal reversing a decision of the first court: ‘The need for appellate caution in reversing the trial judge’s evaluation of the facts is based upon much more solid grounds than professional courtesy. It is because specific findings of fact, even by the most meticulous judge, are inherently an incomplete statement of the impression which was made upon him by the primary evidence. His express findings are always surrounded by a penumbra of imprecision as to emphasis, relative weight, minor qualifications and nuance (as Renan said, la verite est dans une nuance), of which time and language do not permit exact expression, but which may play an important part in the judge’s overall evaluation.’ and ‘Where the application of a legal standard such as negligence or obviousness involves no question of principle but is simply a matter of degree, an appellate court should be very cautious in differing from the judge’s evaluation.’
