The 'OncoMouse' or 'Harvard mouse' is a type of
laboratory mouse that has been
genetically modified using modifications designed by Philip Leder and Timothy Stewart of Harvard University to carry a specific
gene called an activated
oncogene. The activated oncogene significantly increases the mouse’s susceptibility to
cancer, and thus makes the mouse suitable for
cancer research. The rights to the invention are owned by Dupont. OncoMouse(R) is a registered trademark.
[1]
Patent applications on the OncoMouse were filed back in the mid-
1980s in numerous countries such as in the
United States, in
Canada, in
Europe through the
European Patent Office (EPO) and in
Japan.
Patent procedures
Canada
In Canada, the
Supreme Court in 2002 rejected the patent in ''
Harvard College v. Canada (Commissioner of Patents)'', overturning a
Federal Court of Appeal verdict which ruled in favor of the patent by overturning a lower court's rejection. However, on 7 October 2003, Canadian patent 1,341,442 was granted to Harvard College. The patent was amended to omit the "composition of matter" claims on the transgenic mice. The
Supreme Court had rejected the entire patent application on the basis of these claims, but Canadian patent law allowed the amended claims to grant under pre-GATT rules and the patent remains valid until 2020.
Europe (through the EPO)
European patent application 85304490.7 was filed in June
1985 by "The President and Fellows of
Harvard College". It was initially refused in
1989 by an examination division of the European Patent Office among other things on the grounds that the
European Patent Convention (EPC) excludes patentability of
animals per se. The decision was
appealed and the
Board of Appeal held that ''animal varieties'' were excluded of patentability by the EPC (and especially its Article 53(b)), while ''animals'' (as such) were not excluded from patentability.
[2] The examination division then granted the patent in
1992 (its publication number is EP 0169672).
The European patent was then
opposed by several third parties, more precisely by 17 opponents, notably on the grounds laid out in Article 53(a) EPC,
[3] according to which "inventions, the publication or exploitation of which would be contrary to "
ordre public" or
morality are excluded from
patentability. After opposition proceedings took place in November
2001, the patent has been maintained in amended form. This decision was then appealed and the appeal decision was taken on
July 6,
2004.
[4] The case was remitted to the first instance, i.e. the opposition division, with the order to maintain the patent on a newly amended form.
United States
In
1988, the
United States Patent and Trademark Office (USPTO) granted to Harvard College
claiming “a transgenic non-human mammal whose germ cells and somatic cells contain a re-combinant activated oncogene sequence introduced into said mammal…” The claim explicitly excluded humans, apparently reflecting moral and legal concerns about patents on human beings, and about modification of the human genome. Remarkably, there were no US courts called to decide on the validity of this patent. Two separate patents were issued to Harvard College covering methods for providing a cell culture from a transgenic non-human animal (U.S. 5,087,571) and testing methods using transgenic mice expressing an oncogene (U.S. 5,925,803). U.S. 5,925,803 expires in July 2016.
