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.
