There is nobody acceptable form of an S-signature. Rather, so long as the needs for S-signatures are satisfied, virtually any S-signature will certainly be accepted by the USPTO.

The Rules

37 CFR 1.4(d)(2) sets forth the following four needs for a precious S-signature:

It should consist of only letters and/or Arabic numbers, together with appropriate spaces, commas, periods, apostrophes, or hyphens because that punctuation; It should be placed in between forward slashes; The human signing should insert his or her very own signature; and The surname of the human signing have to be printed or typed immediately adjacent to the S-signature, and also be reasonably specific, therefore the identity of the signer have the right to be conveniently recognized. In addition, the S-signature that a registered patent practitioner should be add by a it is registered number.

This ascendancy places limitations on the type of the S-signature. The does not restrict content, however. Consequently, a wide range of s-signature formats are acceptable. In fact, the USPTO instructs employees who testimonial S-signatures no to refuse or refuse correspondence based upon the contents of the S-signature so long as it adheres to the vast criteria set forth above.

There’s a significant problem v the example sheet you attach to, and, actually, with the instances you give, too. All of the “proper” signatures top top the sheet room a complete name (First I. Last), which has actually led part examiners and clerks in ~ the PTO come decide the the rule somehow require a full name to be a proper signature.

That’s simply not true – as lengthy as you follow the rule you posted – the characters noted in section 1 between slashes as in section 2 – ANYTHING have the right to be one s-signature. In fact, it makes sense not to usage your full name, since anyone can enter that, however an arbitrary personality string is identifiably yours.
