Patent data have diversely technological information of any technology field. So, many companies have managed the patent data to build their R&D policy. Patent analysis is an approach to the patent management. Also, patent analysis is an important tool for technology forecasting. Patent clustering is one of the works for patent analysis. In this paper, we propose an efficient clustering method ...

This Essay explores the largely overlooked relationship between claim construction and patent assertion entities (patent “trolls”) finding that claim construction problems and trends benefit patent assertion entities. First, the Federal Circuit is deeply divided as to the proper approach to claim construction. This split is a significant contributor to uncertain patent scope, which is widely-re...

proximity of the vagus nerve to a patent ductus arteriosus (pda) can cause traction or entrapment of vagus nerve during surgical closure of the in rare occasions. this can lead to a life threatening postoperative bradycardia. herein, we report a case of bradycardia caused by unexpected irritation of the vagal trunk by the end of operation. the patient was managed by re-opening the chest, lung r...

Google Patents (www.google.com/patents) includes over 8 million full-text patents. Google Patents works in the same way as the Google search engine. Google Patents is the global patent search engine that lets users search through patents from the USPTO (United States Patent and Trademark Office), EPO (European Patent Office), etc. This study begins with an overview of how to use Google Patent a...

We analyze patent licensing by a patent holder to downstream technology users. We study how the structure and level of royalties depends on the patent’s strength, i.e., the probability it would be upheld in court. We examine the social value of determining patent validity before licensing, in terms of deadweight loss (ex post) and innovation incentives (ex ante). When downstream users do not co...

At present, I am carrying out a study of the European patent system from an administrative law/governance and comparative law perspective. Even though in the US, several patent scholars have been doing research on applying administrative law principles to the US patent system (notably Arti K. Rai, John F. Duffy, Craig Allen Nard and Kali N. Murray), in Europe the lack of attention to administra...

A total of 1421 patents are retrieved from USPTO patent database and patent citation network is estab...

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 off...
