Legal Validity Metrics for Patent Offices and Law Firms e Recycling of Patent Court Appeal Decisions for Quality Management

In all relevant patent systems an adversely affected party has the possibility to appeal the patent office’s decision in front of a patent court or Board of Appeal (BoA). Within a European context, the EPO is, in a way, even engaging in de facto competition with national patent offices. As an example, the German Patent and Trademark Office (DPMA) provides quasi identical patent products and offers the same kind of legal recourse to the German patent court (BPatGer) for these products. Both offices offer an opposition procedure which is open for appeal, and also in the case of a refusal, both offices offer the possibility of appeals. Thus, the EPO Boards of Appeal are engaged in making decisions every year on around 2000 cases and, e.g., the BPatGer on 600 cases regarding the legal validity of the first instance’s work. It is thus remarkable that, so far, nobody has systematically included the work of the patent courts in a statistical legal validity evaluation in the context of the Patent & Trademark Offices’ (PTOs’) quality assurance systems. Since there is obviously a need to establish a common standard for the comparison of first and second instance legal teachings in patent law, a methodology for comparative legal validity analysis is proposed in this paper. I have tested and optimised the approach while working as a project manager at the European Patent Office, based on analysis of 2300 appeal decisions from seven annual batches. 2014 Elsevier Ltd.
