declaration

A written statement made with the understanding that willfully providing false information is punishable by fines or imprisonment or both. In the U.S., declaration may be used instead of an oath (a sworn statment) to verify that information being submitted to the USPTO is true. MPEP 602, MPEP 715, MPEP 716.

A statement executed in a patent application stating among other things that the applicant has made the invention described therein.

a document in which an applicant for patent declares, under penalty of fine or imprisonment, or both (18 USC 1001), that (1) he or she is the original or sole inventor, (2) shall state of what country he or she is a citizen, (3) that he or she has reviewed and understands the contents of the specification and claims which the declaration refers to, and (4) acknowledges the duty to disclose information that is material to patentability as defined by 37 CFR § 1.56. An oath or declaration must be filed in each nonprovisional patent application.

-- see oath; 35 USC § 115; 37 CFR §§ 1.63 - 1.69; MPEP 602 and the PTO/SB/01 form for more

A statement that establishes an identifier and associates attributes with it, without necessarily reserving its storage (for data) or providing the implementation (for methods). See also definition.

An "assertion" that states something exists and perhaps describes what it's like, without giving any commitment as to how or where you'll use it. A declaration is like the part of your recipe that says, "two cups flour, one large egg, four or five tadpoles..." See "statement" for its opposite. Note that some declarations also function as statements. Subroutine declarations also act as definitions if a body is supplied.
