What is an s-signature?

An s-signature is a legal way to sign an electronic document using a typed signer’s name instead of an actual signature. The signer types their name on the signature line of a document between two forward slashes (for example, /Jimmy Doe/). In the case of conformed signatures, which are another type of s-signature, the signer puts an “s” between two forward slash marks in front of their typed name (for example, /s/ Jimmy Doe). In fact, the s-signature name took its name from the conformed signature style.

Why use s-signatures?


Electronic signatures are necessary to keep business moving, especially when you can’t meet face to face. You never want technical issues to get in the way of collecting signatures. S-signatures make it especially simple to collect them, regardless of a person’s device or tech savviness.


Depending on where and how you are doing business, the option of an s-signature may help you conduct business more quickly by speeding up the signing process. For example, when you’re e-filing a patent application, you can quickly use a form-fill app to add a digital signature from any keyboard. This is just one of many possible examples of when an s-signature might work better than a wet signature.

Ensure your s-signature is valid.

While s-signatures are relatively easy to add to an electronic document, the signatory (the person signing) must follow certain signature requirements:.

  • Sign only using letters, Arabic numerals, or a combination of both in your s-signature.
  • Use the appropriate spacing between words.
  • Include any other necessary punctuation (commas, periods, hyphens).

Remember, the signature must be between forward slashes to make it valid. You must add an s-signature for yourself. Another party cannot add it.


The rules around e-signature validity vary from country to country and region to region.

For example, there are many laws that cover the validity of e-signatures in the United States. The Uniform Electronic Transactions Act (UETA) in 1999 and the US Electronic Signatures in Global and National Commerce (ESIGN) Act in 2000 both set regulatory guidelines on electronic signatures, but every state has not adopted these.

The United States Patent and Trademark Office (USPTO) and many other government agencies accept s-signatures for electronic filing. The Manual of Patent Examining Procedures (MPEP) 501 and 502 also covers regulations on s-signatures for patents.

Questions about electronic signatures? We’ve got answers.

What is a conformed signature?
A conformed signature is a type of electronic s-signature where the signer puts an “s” between two forward slash marks in front of their typed name (for example, /s/ Jimmy Doe). The conformed s-signature style also eliminates the need for an individual to print, sign, or scan a document to submit it electronically.
What is the symbol used to indicate an electronic signature?
There are many forms of e-signatures, each having its own specific uses and formatting requirements. One of the symbols to indicate an electronic signature is /s/, placed before the signer’s name. For example, /s/ Jimmy Doe. The other symbol is the signer’s name between two forward slashes, typed out, for example, as /Jimmy Doe/.
What does an electronic signature look like?

You might think that an electronic signature refers to the box where you sign your name with your stylus or finger. Electronic signatures can, indeed, look like that — or you can eliminate the actual signing step entirely by typing out your full name within the space. Depending on the symbols used, both are valid versions of electronic signatures.
