If I have a drawing of my idea on paper, what will happen now?

It is strongly recommended that you consult with an intellectual property attorney concerning the protection of your idea. The attorney can search patent databases to determine if your idea is novel or whether others have developed the same or similar solutions. Sometimes reviewing such a patent search will assist an inventor in arriving at the best solutions. The attorney can recommend whether or not it is worth the inventor's time to proceed with further development. And, the attorney can assist the inventor in drafting and negotiating an agreement for prospective investors who want to see what you have and how your solution compares with what others have done.

Work with a patent attorney and file a provisional application describing how to make and use your idea. Your drawing would be part of the application. That way - you can tell potential investors that your concept is PATENT PENDING and CONFIDENTIAL - so they should not want to copy it.

Have each person or company sign a nondisclosure agreement prior to sharing your idea. A signed nondisclosure agreement is their concession that you own the idea, that the idea is proprietary information, and that they can't and won't share your idea with anyone else.

Speak privately with an intellectual property attorney.
