Office Action

§102 §103 §DP
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 1-7 in the reply filed on 10/31/25 is acknowledged. Claim 8 is withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim.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 10/31/25. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. Claims 1-3, 5-7 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 5, 6, 8, 10 of U.S. Patent No. 7128854. Although the claims at issue are not identical, they are not patentably distinct from each other. 7128854 recites the contents of claim 1 are recited in claims 5, 6, 10 7128854 recites the contents of claim 2 are recited in claims 5, 6, 10 7128854 recites the contents of claim 3 are recited in claims 5, 6, 10 7128854 recites the contents of claim 5 are recited in claims 8, 10 7128854 recites the contents of claim 6 are recited in claims 8, 10 7128854 recites the contents of claim 7 are recited in claims 8, 10 Claims 4 is rejected on the ground of nonstatutory double patenting as being unpatentable over claims 5, 6, 8, 10 of U.S. Patent No. 7128854 in view of Watanabe (US 2004/0091567). Although the claims at issue are not identical, they are not patentably distinct from each other. 7128854 does not explicitly recite the content claim 4 Watanabe teaches a controller for an injection molding device [Abstract] wherein the input device also includes display means (CRT or LCD) for displaying and inputting various parameters and set values [0051]. 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 and included a display screen used to set the first condition, as suggested by Watanabe, as this configuration had demonstrated success in molding applications and was a known technique for input/output of measured/set parameters. Claims 1-3, 5-7 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-3, 14, 17 of U.S. Patent No. 7485247. Although the claims at issue are not identical, they are not patentably distinct from each other. 7485247 recites the contents of claim 1 are recited in claims 1-3, 14 7485247 recites the contents of claim 2 are recited in claims 1-3, 14, 17 7485247 recites the contents of claim 3 are recited in claims 1-3, 14, 17 7485247 recites the contents of claim 5 are recited in claims 1-3, 14 7485247 recites the contents of claim 6 are recited in claims 1-3, 14, 17 7485247 recites the contents of claim 7 are recited in claims 1-3, 14 Claim 4 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-3, 14, 17 of U.S. Patent No. 7485247 in view of Watanabe (US 2004/0091567). Although the claims at issue are not identical, they are not patentably distinct from each other. 7485247 does not explicitly recite the content claim 4 Watanabe teaches a controller for an injection molding device [Abstract] wherein the input device also includes display means (CRT or LCD) for displaying and inputting various parameters and set values [0051]. 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 and included a display screen used to set the first condition, as suggested by Watanabe, as this configuration had demonstrated success in molding applications and was a known technique for input/output of measured/set parameters. 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. Claims 1-3, 5-7 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Amano (US 2007/0007683). As to claim 1, Amano teaches a control device of an injection molding machine including an injection member that is provided in a cylinder (21) heating a molding material and an injection drive source (11) that causes the injection member to advance to fill an inside of a mold unit with the molding material, the control device comprising: an injection control unit (26) that performs a retreat speed limitation to limit an actual speed value of the injection member to a first set value or less during retreat of the injection member [Abstract] in a holding pressure process for controlling a pressure acting on the molding material from the injection member [0010, 0011, 0012, Fig 4], wherein the injection control unit releases the retreat speed limitation in a case where a first set condition is satisfied while the retreat speed limitation is performed (ie when the 2nd amount is greater than the first amount) [0032, 0074, 0075]. Examiner notes that Amano refers to the difference between actual pressure and preset pressure as a “second amount” and the difference between actual speed and the preset speed as a “first amount.” As to claim 2, Amano teaches the first set condition includes a condition in which the pressure satisfies a preset condition ie when the detected/actual pressure exceeds hold pressure preset value [0079]. As to claim 3, Amano teaches the first set condition includes a condition in which an actual value of the pressure exceeds a preset upper limit [0079]. As to claim 5, Amano teaches the injection control unit releases the retreat speed limitation and controls the actual speed value of the injection member to a second set value larger than the first set value during the retreat of the injection member [0044] as when the 2nd amount is greater than the first amount the limit is released and speed control is performed which implicitly would be higher speed than the limit. As to claim 6, Amano teaches the injection control unit performs the retreat speed limitation again in a case where a second set condition is satisfied after the release of the retreat speed limitation (ie when the first amount is greater than the 2nd amount) [0032, 0074, 0075]. As to claim 7, Amano teaches the injection member (23); and the injection drive source (11) [Fig 2]. Claim Rejections - 35 USC § 103 The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. 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(s) 4 are rejected under 35 U.S.C. 103 as being unpatentable over Amano (US 2007/0007683) in view of Watanabe (US 2004/0091567). As to claim 4, Amano notes a an input device for the controller and measured parameters [0058-0059] further comprising: a display control unit that displays a screen used to set the first set condition on a display unit. Watanabe teaches a controller for an injection molding device [Abstract] wherein the input device also includes display means (CRT or LCD) for displaying and inputting various parameters and set values [0051]. 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 Amano and included a display screen used to set the first condition, as suggested by Watanabe, as this configuration had demonstrated success in molding applications and was a known technique for input/output of measured/set parameters.
