On Cobraf LEN4-Eye gave the reference to a German patent application, by Heinrich Hora
http://www.google.com/patents/DE102012015801A1?cl=en
This patent does not patent LENR itself, nor a reactor, but a "trick" to maintain the property of nanostructures used in some LENR protocols
The idea is simply to prevent those structure to be destroyed at high temperature...
This is a very serious and rational way to patent LENR...
Normally when working on a disruptive technology the best practice is to patent some details, tricks, application, because the rest is either unpatentable science, or easily circumvented process.
Hora is mostly known for proposing a theory about George Miley's experimental results, the "Hora-Miley" Theory.
The patent claims seems quite general, just stating that secret is to prevent sintering of nanostructure... it justs adds some second-chance claims with more specificity...
Maybe is it simply a coquetry patent, just to add to the patent count of a scientists, or to reassure investors... Anyway it seems above average.
