What is the difference between an oath and a declaration in patent applications?

An oath is a sworn statement made before a person authorized to administer oaths, while a declaration is a written statement that can be used in lieu of an oath. According to MPEP 602, “A declaration may be submitted in lieu of an oath in any document filed in the Office provided the declaration complies with the requirements of 37 CFR 1.68.” Declarations are often preferred because they don’t require appearing before an official and are easier to process electronically.
