FWIW I'm a registered US Patent Agent and draft/prosecute patents daily. As many of you know, what is disclosed in the application may have little bearing on what actually makes it to market, and most of the language in the application is boiler plate type stuff that isn't really any more informative about the final product than the cryptic spec sheet they released yesterday. What they are actually trying to get protection for in the claims is a fairly generic device...a cell phone with detachable modules and a specific case configuration with a grip and a particular set of screws that extends through the case. The file history is publicly available on the USPTO, and the claims are overly broad IMHO and FWIW currently stand rejected by the USPTO. The application is also a continuation-in-part of a 2014 application (and if it is written properly includes all the disclosure of the 2014 application, which it should), so there may be more of interest in the 2014 application but I haven't read it yet.
The thing that interests me potentially most about the phone is a paragraph in the application that provides support for slapping a sensor with the specs of a RED Scarlet, Epic, or Weapon on or into the device. This is most likely just boiler plate taken from another one of their patents or patent apps as it stands, and there are most likely technical hurdles that would prevent them from doing this, but if they could pull off a module with a stills/motion sensor with current RED tech in a consumer product at a reasonable price that could fit in ones pocket, that would interest me very much. Of course as noted their delivery windows or lack thereof make it difficult to get excited about any of their products, and we may see the iPhone 9 or 10 before the base Hydrogen unit even starts shipping widely.
