Response to Arguments
The arguments have been fully considered, but have not been found to be persuasive.
In response to Applicants argument on pages 6-7 regarding newly amended claim language,
The examiner respectfully responds the Applicants arguments are directed to new amendments to the claim language, which have been addressed in the rejection below.
Claim Objections
Claim 5 is objected to because of the following informalities: Claim 5 recites the limitation “the rails”, however, this element has yet to be invoked, while the line directly above this new limitation does give weight to “equipment support rails”. To obviate the objection, the Examiner would suggest amending “the rails” to “the equipment support rails”. Appropriate correction is required. All dependent claims are similarly objection to for depending from an objected to claim.
Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 1-4 are rejected under 35 U.S.C. 103 as being unpatentable over Cursetjee et al (US 2011/0097986), hereinafter referred to as Cursetjee, in view of Gustin et al (US 4883511), hereinafter referred to as Gustin.
Regarding claim 1, Cursetjee (US 2011/0097986) shows a ceiling diffuser system comprising:
a. a grid support structure (10, Fig. 1/2) with members (34, 36, 38, 40, Fig. 4) releasably connected to form the grid support structure (¶0019, Lines 18-22),
b. a perimeter (14, Fig. 1 – ¶0004, Lines 14-18 – the perimeter facilitates equipment for ventilation) supported by the grid support structure (Fig. 1), and the perimeter is located below the grid support structure (Fig. 1/8 – as the Applicant shows wherein the array of laminar airflow diffusers 40 are located below the grid support structure 28 by showing the bottom of the structure of the laminar airflow diffusers 40, which are attached to the grid support system 28, being understood as being located below the grid support structure 28, as does Cursetjee show with the perimeter 14 being located below the grid support system 10),
c. an equipment support module (30, Fig. 2) releasably connected to and supported by the grid support structure (Fig. 1/4).
However, Cursetjee lacks showing an array of laminar airflow diffusers.
Gustin (US 4,883,511), a ceiling mounted HVAC system, is in the same field of endeavor as Cursetjee which is a ceiling mounted system with HVAC properties.
