Inventors are encouraged to maintain their invention confidentially during the initial invention stages until they have a patent application filed. If you must disclose your invention to a third-party such as a mold maker, you should secure a Confidentiality Agreement with the third-party to ensure that they will not disclose your invention to another. Not only do you risk having another party “steal” your idea, you potentially can lose valuable patent rights in the United States and in foreign countries by such unprotected disclosures.
