Can I sell an idea without a proyotype ?

Question

I have something I have been designing, is a concept or design marketable,what are the paremeters?

Answer 1

It is not possible to protect ideas but rather the representation of that idea.

To protect an original invention OR a significant improvement to an existing product, a patent would be filed. Here's the USPTO's definition: http://www.uspto.gov/web/offices/pac/doc/general/index.html#patent

NOLO is a great, free informational site. Also, be sure to read what the USPTO (United States Patent & Trademark Office) has to say about patents.

Associations may be a good avenue to explore. These organizations will address many of the thoughts, questions and concerns you'll inevitably have as well as many you haven't anticipated yet. See the source box for some relevant links.

Research, research, research – this cannot be stressed enough. Read as much as you can. Here are some book titles that are relevant:

Answer 2

Start a patent search to get a date of inception for your idea, an alternative would be to Draw or describe it and have the paper notarized.

Don't offer it for sale as a product until you are ready, offering it for sale starts the 1 year patent clock.

Don't show it to anyone who will not sign a non-disclosure form.

That said, anything is marketable, but it will most likely be worth far less in the design stage.

Good Luck!
