The Reference
In rejecting the claims under 35 U.S.C. § 102(b), the
examiner relies upon the following reference:
Pawlowski, Jr. (Pawlowski) 5,847,734 Dec. 08, 1998
The Rejections
Claims 14, 20, and 23 stand rejected under 35 U.S.C. §112,
second paragraph, as being indefinite for failing to particularly
point out and distinctly claim the subject matter which the
applicants regard as the invention.1
Claim 17 stands rejected under 35 U.S.C. § 102(b) as being
anticipated by Pawlowski.
The Invention
The invention relates to a system for purging air from a
print mechanism. The claimed system vents air from an ink pen
using a valve to regulate pressure within the pen. Air bubbles
which may be trapped in the pen collect in air vents which are
configured to gravitationally channel air upwardly. (Appeal
Brief, page 2, lines 3-17). Further details of the claimed
subject matter are found in the claims reproduced above.
