Recently the English Court of Appeal confirmed that it is not possible to patent a discovered gene sequence. They also explained how, when they disagree with decisions of the European Patent Office (EPO), it is most likely that the court, rather than the EPO, has got it right.

In Eli Lilly v Human Genome, [2010] EWCA Civ 33, the Court of Appeal was considering an appeal from a judgement of Kitchin J in which he had held that European patent (UK) 0939804 of Human Genome was invalid as relating to an unpatentable invention.

In dismissing the appeal, Jacob LJ, giving the judgment of the court, noted that the Technical Board of Appeal (TBA) of the EPO had upheld the European patent, after opposition, on the basis of more restricted claims. He considered the decision making process in the English courts and at the EPO to explain why the English court came to a decision at variance with that of the TBA.

English Courts v the EPO

Jacob LJ commented that first instance trials in England involve intensive investigation and testing of evidence, with acknowledged cost penalties. The evidence is tested by the process of cross-examination. The judge will not only have expertise in patent law but considerable general technical expertise. In this particular case the Court of Appeal had also used a scientific advisor from King's College, London.

The opposition procedure at the EPO was contrasted with this and referred to as "administrative". It was noted that there is no cross-examination and no compulsory disclosure of documents. It was also noted that there is much more latitude for the admission of fresh material on appeal.

Therefore Jacob LJ concluded that the EPO could not investigate matters as profoundly as in a trial in an English court. The Court of Appeal, therefore, would continue to take note of EPO decisions which clearly laid down a principle of law, they would feel able to depart from any EPO decisions which involved the assessing of facts of an individual case.

Can gene sequences be patented?

In concluding that Kitchin J was correct in determining that the invention in this case was not patentable, Jacob LJ commented:

"However clever...
