The US patent application for Andrea Rossi’s e-cat can be viewed online. You can view a copy of the application US 2011/0005506 Al here. It does not mention cold fusion at all instead it describes the device as a “method and apparatus for carrying out nickel and hydrogen exothermal reaction” which seems like a more accurate description of the process. The application has some drawings of the device and the reaction.
According to the paperwork the application was filed on September 16, 2010, and published on January 13, 2011. The US Patent Office is reviewing the application and has not made any decision on it. Rossi does have an Italian patent on the e-cat. The application describes Rossi’s e-cat as a metal tube filled with nickel powder which seems accurate.
The application also lists Rossi’s law firm as Hedman and Costigan PC of New York City. It is not known how the America Invents Act which was passed by the US Senate on September 8 would affect Rossi’s application. That law changes the US patent system from a first to invent to a first to patent one. That would seem to be aid Rossi who does have an Italian Patent.
In a post on his blog, Rossi said his lawyer is studying how the America Invents Act will affect his situation. It is possible that the Patent Office will delay action on this until after the act becomes law.
Rossi is scheduled to begin a demonstration of the e-cat next month. It must also be noted that a lot of other work including the creation of a working electric generator powered by the device needs to be done before it can be sold to the public. Rossi has stated on his blog that he is not able to generate electricity yet.
