I'm a little confused about not wanting to disclose IP during a patent process. Isn't that what the patent process is designed to do? Disclose a novel invention, and have it (among other things) vetted for prior art. They say these patents are pending, in which case, shouldn't they be searchable? Has anyone found them? I did an albeit cursory search and couldn't find anything. I'd like to give these guys the benefit of the doubt as they are funded by a16z, but the lack of information is troubling.
