Appeal No. 98-0605
Application 08/383,191
the seal is between the housing 12 and the covering 36 and
there is no descriptive support for the limitations of "the
blower having a seal" and "the exhaust port seal."
Claims 1-20 and 27 are rejected under 35 U.S.C. § 112,
second paragraph. In order to satisfy the requirements of the
second paragraph of § 112, a claim must accurately define the
invention in the technical sense. See In re Knowlton, 481
F.2d 1357, 1366, 178 USPQ 486, 492-93 (CCPA 1973). Here,
independent claims 1, 16 and 27 do not accurately define the
invention in the technical sense since, as we have noted above
with respect to the rejection under the first paragraph of §
112, there are no conduits in the roof system (rather than the
roof system being "substantially free" from conduits) and all
(rather than "substantially all") of the air is forced di-
rectly into the roof system.
As we have also noted above with respect to the rejection
of claims 1-15 under the first paragraph of § 112, the seal is
between the housing 12 and the covering 36, rather than "the
blower having a seal" and an "exhaust port seal" as set forth
