Can a non-signing inventor later join the patent application?

Yes, a non-signing inventor can later join the patent application. According to 37 CFR 1.64(f):

“A nonsigning inventor or legal representative may subsequently join in the application by submitting an oath or declaration under § 1.63.“

However, it’s important to note that this subsequent submission does not give the non-signing inventor or legal representative the power to revoke or grant a power of attorney if the application was filed under 37 CFR 1.43, 1.45, or 1.46.

This provision allows for flexibility in cases where an inventor’s circumstances may change after the initial filing of the application.
