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 . Claim Objections Claims 1, 11 and 13 are objected to because of the following informalities: Claim 1 appears to have a typographical error in line 15. The examiner respectfully suggests deleting “sensing element”. Claim 11 appears to have a typographical error in line 2. The examiner respectfully suggests deleting “sensing element”. Claim 13 appears to have a typographical error in line 4. The examiner respectfully suggests deleting “sensing element”. Appropriate correction is required. 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, 3-6, 11-13, 17, 18 and 20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by U.S. Patent 10,222,286 issued to Imai et al. (“Imai”). As for claim 1, Imai discloses a pressure sensing device (Figs. 4 and 8), comprising: a first elongated hollow member (“first elongated hollow member” in annotated Fig. 8 below) comprising a first opening (“first opening” in annotated Fig. 8 below) located at a first end of the first elongated hollow member; a second opening (“second opening” in annotated Fig. 8 below) located at a second end opposite to the first end of the elongated hollow member, wherein the second opening is open to atmosphere; and a third opening (“third opening” in annotated Fig. 8 below) located at between the first and the second end of the first elongated hollow member, a second elongated hollow member (“second elongated hollow member” in annotated Fig. 8 below), the second elongated hollow member being connected to the first elongated hollow member via the third opening (see annotated Fig. 8 below), wherein the first opening being configured to connect an inside of the second elongated member to an inside of a third hollow member (se annotated Fig. 8 below); one of a free end (“free end” in annotated Fig. 8 below) of the second elongated member or third opening configured to open out to external atmospheric pressure through an aperture (“aperture” in annotated Fig. 8 below); and a pressure sensor (20, 22b) being connected to the other one of the free end of the second elongated member or the third opening. PNG media_image1.png 720 1280 media_image1.png Greyscale As for claim 3, the examiner notes that this limitation describes the intended use of the pressure sensing device (i.e. to be used with a third hollow member with the claimed pressure) and does not structurally distinguish the claimed invention over the prior art. As for claim 4, Imai discloses that the first elongated hollow member (“first elongated member”) comprises a first portion (21a) with a first length and a first inner diameter (see Fig. 8) and a second portion (21) with a second length and a second inner diameter (see Fig. 8). As for claim 5, Imai discloses that the first portion (21a) is located at the first end of the first elongated hollow member (see Fig. 8). As for claim 6, Imai discloses that the inner diameter of the first portion (21a) is different (see Fig. 8) from the inner diameter of the second portion (21). As for claim 11, Imai discloses that the pressure sensor (20, 22b) is connected to the free end of the second elongated member (see Fig. 4) and the third opening is configured to open out to external atmospheric pressure with the aperture (see Fig. 8). As for claim 12, the examiner notes that this limitations describes the intended use of the pressure sensing device (i.e. to be used with flue) and does not structurally distinguish the claimed invention over the prior art. As for claim 13, Imai discloses method for measuring pressure in a flue, the method comprising: positioning a pressure sensor element outside a flue using a pressure sensing device according to claim 1 (the examine notes that Fig. 4 shows that the pressure sensing device is not positioned near a flue). As for claim 17, Colvin discloses that the inner diameter of the first portion (21a) is different from the inner diameter of the second portion (21). As for claim 18, Colvin discloses that the first inner diameter (at 21a) is bigger (see Fig. 8) than the second inner diameter (at 21). As for claim 20, Colvin discloses that the first elongated hollow member comprises a first portion (21a) with a first length and a first inner diameter and a second portion (21) with a second length and a second inner diameter. 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 2, 7-10, 15, 16 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over U.S. Patent 10,222,286 issued to Imai et al. (“Imai”). As for claim 2, Imai discloses the pressure sensing device according to claim 1 (see the rejections of claim 1 above). Imai does not disclose that the size of the aperture is between 0.4 mm and 1.2 mm. At the time the application was filed, it would have been an obvious matter of design choice to a person of ordinary skill in the art to size the aperture of Imai to be between 0.4 mm and 1.2 mm because Applicant has not disclosed that sizing the aperture between 0.4 mm and 1.2 mm provides an advantage, is used for a particular purpose, or solves a stated problem. One of ordinary skill in the art, furthermore, would have expected Imai’s aperture and applicant’s invention to perform equally well with either the size disclosed by Imai or the claimed size because both sizes would perform the same function of providing a passageway for gas. Therefore, it would have been prima facie obvious to modify Imai to obtain the invention as specified in claim 2 because such a modification would have been considered a mere design consideration which fails to patentably distinguish over the prior art of Imai. As for claim 7, Imai discloses the pressure sensing device according to claim 6 (see the rejection of claim 6 above). Imai does not explicitly disclose that the inner diameter of the first portion is between 3 mm and 9 mm. At the time the application was filed, it would have been an obvious matter of design choice to a person of ordinary skill in the art to size the inner diameter of the first portion of Imai to be between 3 mm and 9 mm because Applicant has not disclosed that sizing the inner diameter of the first portion between 3 mm and 9 mm provides an advantage, is used for a particular purpose, or solves a stated problem. One of ordinary skill in the art, furthermore, would have expected Imai’s inner diameter and applicant’s invention to perform equally well with either the size disclosed by Imai or the claimed size because both sizes would perform the same function of providing a passageway for gas. Therefore, it would have been prima facie obvious to modify Imai to obtain the invention as specified in claim 7 because such a modification would have been considered a mere design consideration which fails to patentably distinguish over the prior art of Imai. As for claim 8, Imai discloses the pressure sensing device according to claim 4 (see the rejection of claim 4 above). Imai does not disclose that the length of the first portion is up to 5000 mm. At the time the application was filed, it would have been an obvious matter of design choice to a person of ordinary skill in the art to size the length of the first portion of Imai to be up to 5000 mm because Applicant has not disclosed that sizing length of the first portion up to 5000 mm provides an advantage, is used for a particular purpose, or solves a stated problem. One of ordinary skill in the art, furthermore, would have expected Imai’s length of the first portion and applicant’s invention to perform equally well with either the size disclosed by Imai or the claimed size because both sizes would perform the same function of providing a passageway for gas. Therefore, it would have been prima facie obvious to modify Imai to obtain the invention as specified in claim 8 because such a modification would have been considered a mere design consideration which fails to patentably distinguish over the prior art of Imai. As for claim 9, Imai discloses the pressure sensing device according to claim 4 (see the rejection of claim 4 above). Imai does not disclose that the inner diameter of the second portion is approximately 3 mm. At the time the application was filed, it would have been an obvious matter of design choice to a person of ordinary skill in the art to size the inner diameter of the second portion of Imai to be approximately 3 mm because Applicant has not disclosed that sizing the inner diameter of the second portion to be approximately 3 mm provides an advantage, is used for a particular purpose, or solves a stated problem. One of ordinary skill in the art, furthermore, would have expected Imai’s inner diameter of the second portion and applicant’s invention to perform equally well with either the size disclosed by Imai or the claimed size because both sizes would perform the same function of providing a passageway for gas. Therefore, it would have been prima facie obvious to modify Imai to obtain the invention as specified in claim 9 because such a modification would have been considered a mere design consideration which fails to patentably distinguish over the prior art of Imai. As for claim 10, Imai as modified discloses the pressure sensing device according to claim 9 (see the rejection of claim 9 above). Imai does not disclose that the length of the second portion is not more than 50 mm. At the time the application was filed, it would have been an obvious matter of design choice to a person of ordinary skill in the art to size the length of the second portion of Imai to be not more than 50 mm because Applicant has not disclosed that sizing the length of the second portion to be not more than 50 mm provides an advantage, is used for a particular purpose, or solves a stated problem. One of ordinary skill in the art, furthermore, would have expected Imai’s length of the second portion and applicant’s invention to perform equally well with either the size disclosed by Imai or the claimed size because both sizes would perform the same function of providing a passageway for gas. Therefore, it would have been prima facie obvious to modify Imai to obtain the invention as specified in claim 10 because such a modification would have been considered a mere design consideration which fails to patentably distinguish over the prior art of Imai. As for claims 15 and 16, the examiner notes that these limitations describe the intended use of the pressure sensing device (i.e. to be used with a third hollow member with the claimed pressure) and does not structurally distinguish the claimed invention over the prior art. As for claim 19, Imai as modified discloses that the first elongated hollow member (“first elongated member”) comprises a first portion (21a) with a first length and a first inner diameter (see Fig. 8) and a second portion (21) with a second length and a second inner diameter (see Fig. 8). Claim 14 is rejected under 35 U.S.C. 103 as being unpatentable over U.S. Patent 10,222,286 issued to Imai et al. (“Imai”) in view of EP 3534133 by Schon et al. (“Schon”) and U.S. Patent 10,450,061 issued to Collins (“Collins”). As for claim 14, Imai discloses the pressure sensing device according to claim 1 (see the rejection of claim 1 above). Imai does not disclose a 3D printer that prints a device according to claim 1. However, Schon discloses a 3D printer that prints a pressure sensing device (Abstract). It would have been obvious for one having ordinary skill in the art before the effective filing date of the present application to modify the pressure sensing device of Imai by using a 3D printer to print the device as disclosed by Schon in order to allow a complex design of a pressure sensing device to be realized in a simple manner (Schon: see the paragraph beginning “The measuring element receptacle, at which the first fluid terminates …”). Imai as modified by Schon does not explicitly disclose a computer-readable medium having computer-executable instructions adapted to cause a 3D printer to print. However, Collins discloses a computer-readable medium having computer-executable instructions adapted to cause a 3D printer to print (col. 11, lines 7-11). It would have been obvious for one having ordinary skill in the art before the effective filing date of the present application to modify the 3D printer of Imai and Schon to be controlled by a computer-readable medium as disclosed by Collins on order to allow the 3D printer to be automatically controlled. Response to Arguments Applicant’s arguments with respect to claim 1 have been considered but are moot in view of the new grounds of rejection. Conclusion 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). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
