One of the services provided for inventors is the acceptance and preservation for a two year period of papers disclosing an invention. This disclosure is accepted as evidence of the dates of conception of the invention.
It will be retained for two years at which time it will be destroyed unless it is referred to in a separate letter in a related patent application.
A fee must accompany the disclosure. See current fee schedule. The disclosure is limited to written matter or drawings on paper or other thin, flexible material, such as linen or plastic drafting material, having dimensions or being folded to dimensions not to exceed 8-1/2 x 13 inches (21.6 by 33.0 cm). Photographs are acceptable. Each page should be numbered. Text and drawings should be of such quality as to permit reproduction.
The disclosure must be accompanied by a stamped, self-addressed envelope and a duplicate copy also signed by the inventor. The papers will be stamped with an identifying number and returned with the reminder that the Disclosure Document may be relied upon only as evidence of the date of conception and that an application must be filed in order to provide patent protection.
