A contract for invention development services shall be in the following form:
"The following disclosures are required by law and are expressly made a part of this contract: You have the right to cancel this contract for any reason at any time within three (3) business days from the date you and the invention developer sign the contract and you receive a fully executed copy of it. To exercise this option you may use certified mail or personally deliver to this invention developer written notice of your cancellation. The method and time for notification is set forth in this contract immediately above the place for your signature. Upon cancellation, the invention developer must return by certified mail or personal delivery, within ten (10) business days after receipt of the cancellation notice, all money paid and all materials provided either by you or by another party in your behalf.
Unless the invention developer is a registered patent attorney or registered patent agent, he is not permitted to give you legal advice concerning patent, copyright or trademark law or to advise you of whether your idea or invention may be patentable or may be protected under the patent, copyright or trademark laws of the United States or any other law.
No patent, copyright or trademark protection will be acquired for you by the invention developer or by this contract. Your failure to inquire into the law governing patent, copyright or trademark matters may jeopardize your rights in your idea or invention both in the United States and in foreign countries. Your failure to identify and investigate existing patents, trademarks or registered copyrights may place you in jeopardy of infringing the copyrights, patent or trademark rights of other persons if you proceed to make, use, distribute or sell your idea or invention.";
