Interference No. 102,922
Interference No. 103,088
above noted Dumas application Ser. No. 07/748,486 assigned to
Hercules, and a U.S. patent No. 5,147,507 filed on behalf of
Gill, originally assigned to Pfizer and now assigned to
Mineral Technologies, Inc. This second interference was
declared as a result of a Dumas 37 CFR § 1.633(c)(1) motion in
‘922 requesting that count 3 directed to a method of making
paper and paperboard be added to ‘922. Since the involved
Gill application in ‘922 did not contain claims directed to
such method but Gill's divisional application, U.S. patent
5,147,507 did, the Administrative Patent Judge (APJ) treated
the Dumas motion as a motion to declare another interference
directed to the method, granted the motion, and declared the
second interference.
The subject matter in issue in the ‘088 interference
comprises a process of making paper or paperboard employing
the
surface treated filler of the ‘922 interference. The count is
set forth in APPENDIX B. Dumas claim 16 and Gill claims 1 and
2 correspond to the count.
No questions of interference-in-fact or separate
