Ambercite and its associate Griffith Hack are proud to announce the official launch of the Ambercite website, www.ambercite.com. We have developed this website to help inform the patent community about the Network Patent Analysis (NPA) service available from Ambercite, and to provide a home site for future developments with NPA. We believe that NPA™ patent analysis offers a major and unique advance on existing methods used in patent landscaping due to its ability to simultaneously rank and group patents.
To help demonstrate the power of NPA™ patent analysis, we have published an updated analysis of key patents in the hybrid car area via a newly published white paper. While Griffith Hack has previously reported on hybrid car patents, the updated report includes a newly developed and highly advanced analysis of the leading patents in this area, and in particular focusing on the leading patents filed by hybrid car technology developers Toyota, Ford and Paice Corporation. We have focused on these three companies, not only because our analysis showed that these companies were owners of the leading patents in this area, but also because patent license agreements have been signed between these three companies. Some of these agreements appeared to be in relation to litigation between these companies.
Our analysis confirmed that there is significant interrelationship between the leading patents filed by these companies, which is consistent with these license agreements.
Our analysis also looked at the NPA™ derived 'apparent technology flows' in and out of the top ten hybrid car patents filed by Toyota, Ford and Paice Corporation. These showed some surprising results. For example, leading Toyota patents appeared to be related to earlier patents filed by Suzuki and Ford, and in turn to be related to later patents filed by Suzuki, Ford and Honda. Leading Ford patents were related to some earlier patents filed by Railpower Technologies, a company that developed hybrid technologies for trains, and in turn to be related to some later patents filed by Chrysler and Honda. Earlier Chrysler patent appeared to related to leading Paice patents, who in turn appear to be related to later patents filed by General Motors and Aisin among other companies.
