What forms should be used for powers of attorney in patent applications filed before September 16, 2012?
For patent applications filed before September 16, 2012, the USPTO recommends specific forms for powers of attorney. According to the MPEP:
Form PTO/SB/80 or PTO/SB/81 (available at www.uspto.gov/patent/patents-forms) should be used for powers of attorney in applications filed before September 16, 2012.
Additionally, for patents that issued from applications filed before September 16, 2012, Form PTO/SB/81A may be used. It’s important to note that the USPTO no longer recommends or provides combined declaration and power of attorney forms. Practitioners should use separate forms for declarations and powers of attorney.
