DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Response to Arguments
Applicant’s arguments with respect to claim(s) 1-4 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claim(s) 1-4 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Ohara et al. (US 2022/0017678 A1).
Re: Claim 1, Ohara teaches a device capable of performing the claimed method of creating a mixture of polyurethane, comprising: mixing an equal amount of polyol and isocyanate to form the polyurethane (Para. 174, 210, equal parts polyol and isocyanate); wherein a gun (20) having two cylinders (12, 14) and a static mixer (18) is used to mix the polyol and the isocyanate (Fig. 1), a first cylinder of the two cylinders containing the polyol and a second cylinder of the two cylinders containing the isocyanate, wherein the gun is configured to dispense polyurethane after mixing the polyol and the isocyanate (Fig. 1, Para. 174, 192, cylinders of polyol and isocyanate).
Re: Claim 2, Ohara teaches a device capable of performing the claimed method of before the mixing step, placing the equal amount of the polyol and the isocyanate in the first cylinder and the second cylinder respectively (Para. 174, 210, equal parts polyol and isocyanate).
Re: Claim 3, Ohara teaches a device capable of performing the claimed method of the polyurethane is fast-expanding polyurethane or slow-expanding polyurethane (Para. 13, slow expanding foam due to slow foam rotation for higher density and flame retardancy).
Re: Claim 4, Ohara teaches a device capable of performing the claimed method of the equal amount of polyol and the isocyanate are dispensed from the two cylinders into the static mixer, then mixed to form the polyurethane, then dispensed from the gun to be applied to a surface (Para. 196, 210-211, equals parts mixed and dispensed).
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. PTO-892 provides additional references of dispenser having mixers for polyurethane.
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
