Documents posted on the European Patent Office’s Patent Register show that a patent that had been previously granted of Italian inventor Francesco Piantelli has now been revoked after opposition from Andrea Rossi’s Leonardo Corporation.

The patent is titled “Method and Apparatus for Generating Energy by Nuclear Reactions of Hydrogen Adsobred by Orbital Capture on a Nanocrystalline Structure of a Metal”.

This document contains the revocation decision: https://register.epo.org/application?documentId=E0116UAJ7368DSU&number=EP12728780&lng=en&npl=false

Leonardo Corporation opposed the patent on the grounds of: “lack of novelty, inventive step and industrial application” and “the patent does not disclose the invention in a manner sufficiently clear and complete for it to be carried out by a person skilled in the art”, both of which are required according to European patent law.

This document provides the grounds for the decision, and includes evidence from Leonardo as to why they contend the patent is invalid. https://register.epo.org/application?documentId=E0116UGI9854DSU&number=EP12728780&lng=en&npl=false

It shows that Rossi and Leonardo have been very thorough and aggressive in trying to assert supremacy in the IP field, and this would have to be considered a win for them. These documents do state however that the decision of revocation can be appealed, and it is very possible that Piantelli’s team will do that.
