It's a great "revolutionary" devise he believes is a disruptive technology during this industry, I totally agree. Indeed, I made a decision to assistance with creating a business plan. Thus, I am going to print out the information we discussed in emails and speak to calls, and look at it and make use of that material in the commercial plan, where they fit.
Since all of this is preliminary, nothing is set in stone, it's wise to maintain all of the notes, and away from view of others in the marketplace. In addition, it is sensible to use "discreet manufacturing" tips for the very first prototypes, and use an LLC name seems as if you are doing something different makes sense; in cases like this, perhaps, an LLC that suggests something totally un-related.
In this way when you get a store somewhere, who'll know what the hell you do unless you roll-up the doorway 1 day to show the planet; remember; "Loose lips sink ships!" The truth is, having a new invention means you need to maintain your information near to the vest while you design, build, and get your patent work in order. Should you be discreet rather than allow your enthusiasm to allow you to go and tell everyone what you're doing, you'll be much better off in the long run. Please consider this all.
