Comments from Speaker

In 2015, important Supreme Court Decisions were issued with respect to PBP (product-by-process) claims. For the next few years, judgements on PBP claims by the JPO seemed to be unclear, unstable and, in some cases, rather confusing. Recently however, the JPO’s judgements on PBP claims seem to have settled, and we can give more appropriate advice on responses to an objection regarding PBP claims. In this seminar, we will provide information which will be useful for getting PBP claims granted for inventions in the fields of chemistry, biotechnology and medicines, in particular by making arguments for “impossible/impractical” circumstances.
