Over the years, I've had the opportunity to be involved in all sorts of interesting innovations.
Some of the projects were my ideas and concepts.
On others, I only worked as a component of the project, or advised in some consulting fashion.
Not long ago, I was discussing a great invention idea with an acquaintance as he was considering launching a new product.
It is a great "revolutionary" devise that he believes will be a disruptive technology in this particular industry, I totally agree.
Indeed, I decided to assist in creating a business plan.
Thus, I am going to print out the information we discussed in emails and phone calls, and go over it and use that material in the business plan, where it fits.
Since all this is preliminary, nothing is set in stone, it makes sense to keep all the notes, and away from view of others in the industry.
It also makes sense to use "discreet manufacturing" strategies of the first prototypes, and use an LLC name that looks like you are doing something else makes sense; in this case, perhaps, an LLC that suggests something totally un-related.
This way when you get a shop somewhere, who'll know what the hell you are doing until you roll-up the door one day to show the world; remember; "Loose lips sink ships!" You see, having a new invention means you have to keep your information close to the vest as you design, build, and get your patent work in order.
If you be discreet and not allow your enthusiasm to cause you to go and tell everyone what you are doing, you'll be much better off in the long term.
Please consider all this.
