Research output: Contribution to journalArticlepeer-review


The article examines the impact of the directive by the European Patent Office on human embryonic stem (hES) cells patenting strategy and its implications on biotechnology industries in Europe. The rule 23 section c of the European Patent Convention directive had prohibited patent protection for hES cell-related technology. This restriction caused patentees to engage in differential wording strategy such as the used restrictive language which limit the commercial value and scope of the technology.
