Office Action

§102 §103
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 . Election/Restrictions Applicant’s election without traverse of claims 1-3 in the reply filed on 2/6/23 is acknowledged. Claims 4-15 withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 2/6/23. 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 1 is rejected under 35 U.S.C. 102(a)(1) as being anticipated by Neter (US 2006/0204605). As to claim 1, Neter teaches A method for producing a preform, comprising: inserting a the preform that has been formed by injection molding [0013, 0007], and that is still hot after having the injection molding [0013, 0007], into a cooling apparatus (50), the cooling apparatus (50) comprising inner contours defining an internal space [0013, 0007], the inner contours of which conform to the outer contours of the preform [Fig 3a-3C], generating a negative pressure being generated between the inner contours of the cooling apparatus and the outer contours of the preform [0045, 0042, 0044, 0034-0036],- pressing at least somewhat an the injection point (80a) (phrased as a gate vestige) created on the preform during the injection molding of the preform against a stamp (72) positioned proximate the injection point by the negative pressure generated between the inner contours and outer contours [0042, 0044]. 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. Claim 3 is rejected under 35 U.S.C. 103 as being unpatentable over Neter (US 2006/0204605). As to Claim 3, Neter teaches the vacuum is from 61 -71 cm Hg which is approximately .81-95 absolute bar which is an overlapping range with wherein the negative pressure is less than 0.9 bar absolute pressure [0045]. It has been held that choosing the over lapping portion of the range taught in the prior art is a prima facie case of obviousness, see MPEP 2144.05 I. Claim 2 is rejected under 35 U.S.C. 103 as being unpatentable over Neter (US 2006/0204605) in view of Takehana (WO 2020209294 with US 2022/0143886 utilized as translation). As to claim 2 Neter notes that “gate vestige” (ie the mark left at injection point) is generally regarded as a defect to be avoided [0003, 0007] but does not explicitly state the injection point has a length and height of less than 1 mm after pressing. Takehana teaches a cooling mold [Abstract] wherein the gate portion (ie the gate vestige or injection point) is entirely removed by pressing [0095, 0061, 0029, 0031-0033, 0038, Fig 6a, 6b, claim 3, 7]. As this shortens the production cycle by cooling and removing the gate simultaneously in order to avoid a cutting step [0095, 0005]. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have altered the invention of Neter and performed the pressing such that the injection point has a length and height of less than 1 mm after pressing (ie flattened entirely), as suggested by Takehana, in order to shorten the production cycle by cooling and removing the gate simultaneously in order to avoid a cutting step. Claim 2 is rejected under 35 U.S.C. 103 as being unpatentable over Neter (US 2006/0204605) in view of Farrell (US 4005969). Note this is an alternative rejection of claim 2 As to claim 2, Neter notes that “gate vestige” (ie the mark left at injection point) is generally regarded as a defect to be avoided [0003, 0007] but does not explicitly state the injection point has a length and height of less than 1 mm after pressing. Farrell teaches a mold for parisons [Abstract, Fig 2] wherein the injection point is pressed by a stamp (92) phrased as a plunger [col 4 line 35-48, col 5 line 22-38 Fig 2]. Farrell notes that the plunger can be any desired shape to impart whatever shape the user desired to the end product [col 4 line 35-48, col 5 line 22-38 Fig 2]. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have altered the invention of Neter and shaped the plunger such that the pressing resulted in the injection point has a length and height of less than 1 mm, as suggested by Farrell, as the plunger could be configured to any desired shape.
