Where an attorney or agent files a request on behalf of a
patent owner, he or she may act under a power of attorney under
37 CFR 1.32
, or
in a representative capacity under
37 CFR 1.34
. In order to act in a
representative
capacity under
37 CFR 1.34
, an attorney or agent must
provide his or her registration number, name, and signature. In order to act under a power
of attorney from a patent owner, an attorney or agent must be provided with a power of
attorney by the patent owner. Pursuant to
37 CFR 1.32(c)
a

"power of attorney may only name as

practitioners. Thus, an attorney or agent representing a patent owner must be a registered
patent practitioner. A patent owner may not be represented during a supplemental
examination proceeding or any resulting
ex parte
reexamination
proceeding by an attorney or other person who is not registered to practice before the
Office.
Any correspondence from the Office will be directed to the patent owner at the
address indicated
in the file of the patent for which supplemental
examination is requested, pursuant to
37 CFR 1.33(c)
, regardless of the
address of the person filing the request
. If the patent owner wishes the Office to direct correspondence regarding the
supplemental examination proceeding to an address other than the official correspondence
address of record in the file of the patent, then the patent owner must file a change of
correspondence address
in the file of the patent
.
A change of correspondence
address should also be filed in the supplemental examination proceeding. See
MPEP §
2805
.
