First step to monetize our technology

As a former investor and now IP valuation and strategy expert I think you should either file your patents in a PCT recognized area in a first-to-file jurisdiction (Japan is good, US is better, Israel is best) or not file at all. If you file your patents, your patent agent will conduct a Prior Art Search and will let you know if there are any competing or precedent technologies that could cause infringement problems. Patent applications provide you some protection from a partner or investor stealing your ideas, but they also give you the ability to monetize them in a variety of unique financing transactions. If you don't file your patents before your market your inventions, I suggest your pitch focus on what your product does and how it performs; to this end if you've got working prototypes then you've got a great story.

And my opinion on NDAs is that most don't have strong enough enforcement language so that they can be enforced. If your NDA looks like this, then don't both with it, just write "Private and Confidential" on everything... You could also secure your technical documents by posting them to a Virtual Data Room where authorized users can only look at and not print or copy or share.

Best of luck to you, I'd be happy to help in any other way if you'd like to talk further.
