Office Action

§103 §112
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 Rejections - 35 USC § 112(b) The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 4 and 14 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claims 4 and 14 recite: 4. The apparatus of claim 1, wherein the filtering element defines a cavity configured to abut the orifice. Emphasis added. 14. The integrated flow regulating component of claim 11, wherein the filtering element defines a cavity configured to abut the orifice. Claims 4 and 14 are each indefinite because it is unclear whether the recitation of “a cavity” refers to the “cavity” of claims 1 or 11. 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claims 1, 2, 8, 10 and 21 are rejected under 35 U.S.C. 103 as being unpatentable over Jarolics, US 4,772,454 in view of Padden et al., US 5,319,986. Regarding claim 1, Jarolics teaches a system utilizing the probe seen in the Fig. for extracting a gas sample from a gas flow. See Jarolics Fig., col. 1, ll. 5–7. The system reads on the “apparatus.” The system comprises some type of manifold, which is the ductwork that holds the probe. While Jarolics is silent as to the exact structure of the ductwork, Padden teaches a sampler with a magazine system comprising a magazine system 10 (the “manifold”) defining a “gas flow channel” (from conduit 30 through a sampler tube 14 to end space 20 and then to outlet tube 32) that is configured to convey a gaseous substance from an inlet 28 (the “first inlet”) defined on a surface of the magazine system 10. See Padden Fig. 1, col. 2, ll. 21–44. The magazine system 10 holds a plurality of sampler tubes 14, with each sampler tube 14 being similar to the probe of Jarolics. Id. The magazine system 10 is beneficial because it is able to hold a plurality of sampler tubes 14, thereby increasing sampling capacity. PNG media_image1.png 490 724 media_image1.png Greyscale It would have been obvious to provide the probe of Jarolics in the magazine system 10 of Padden to increase sampling capacity. With this modification, the probe of Jarolics reads on the “at least one integrated flow regulating component.” It is removably received within a space 12 of the magazine system of Padden (the space 12 reads on the “second inlet defined on the surface of the manifold”). See Padden Fig. 1, col. 2, ll. 12–17, col. 4, ll. 46–50. The inlet 28 of Padden (the “first inlet”) is different from the space 12 (the “second inlet”), as claimed. The probe of Jarolics comprises an outlet duct 8 (including the physical structure), which reads on the “flow regulating component.” See Jarolics Fig., col. 2, ll. 1–17. The outlet duct 8 defines an “orifice” at the left-hand end (the “first end of the flow regulating component”). Id. The probe also comprises a filter 5 (the “filtering element”) attached to the left-hand end of the outlet duct 8, and defining a cavity 7 (the “cavity”) fluidly coupled with the “orifice.” See Jarolics Fig., col. 2, ll. 1–17. While Jarolics is silent as to the filter 5 being “removably attached” to the left-hand end of the outlet duct 8, it would have been obvious for the filter 5 to be removably attached to the left-hand end of the outlet duct 8 because the reference says that the probe can either have an integral structure or can be composed of several, separable parts. Id. at col, 2, ll. 5–7. The filter 5 leads to the open space inside the outlet duct 8 (the open space reads on the “interior channel of the at least one integrated flow regulating component). Id. at Fig., col, 2, ll. 1–17. The filter 5 is disposed upstream with respect to the orifice because fluid being sampled flows through gas inlet 1 through the filter 5 and then through outlet duct 8. Id. PNG media_image2.png 450 783 media_image2.png Greyscale Regarding claim 2, Jarolics teaches that the filter 5 (the “filtering element”) is at least partially contained within a filter compartment 4 (the “body of the at least one integrated flow regulating component”). Regarding claim 8, Jarolics teaches that the filter 5 (the “filtering element”) comprises a substantially cylindrical member, as seen in the Fig. Regarding claim 10, Jarolics teaches that the probe (the “at least one integrated flow regulating component”) comprises a metal. See Jarolics col. 1, ll. 65–67. Regarding claim 21, Jarolics teaches that the filter 5 is configured to filter the gaseous substance. See Jarolics col. 2, ll. 1–17. Claim 6 is rejected under 35 U.S.C. 103 as being unpatentable over Jarolics, US 4,772,454 in view of Padden et al., US 5,319,986 and in further view of Li et al., US 2016/0349154 A1. Regarding claim 6, Jarolics as modified teaches the limitations of claim 1, as explained above. Jarolics as modified differs from claim 6 because it is silent as to the system comprising a gas detecting apparatus. But the system is used to sample relatively hot gases. See Jarolics col. 1, ll. 5–7. Also, Li teaches an apparatus for sampling syngas comprising a sample container having a pressure gauge and thermometer, which are useful for displaying real-time working pressure and fluid temperature measurements. See Li [0028]. It would have been obvious to include the pressure gauge and thermometer of Li with the system of Jarolics as modified to allow a user to monitor the pressure and temperature of the system. With this modification, the pressure gauge and/or thermometer read on the “gas detecting apparatus.” Claim 7 is rejected under 35 U.S.C. 103 as being unpatentable over Jarolics, US 4,772,454 in view of Padden et al., US 5,319,986 and in further view of Templeton et al., US 6,306,620 B1. Regarding claim 7, Jarolics as modified teaches the limitations of claim 1, as explained above. Jarolics as modified differs from claim 7 because it is silent as to the diameter of the “orifice” at the downstream end of the outlet duct 8. Therefore, the reference fails to provide enough information tot each the “orifice” has a diameter of 0.2 to 2 mm, as claimed. But Templeton teaches a gas collection device with a tube having a diameter of about 1 mm. See Templeton col. 16, ll. 62–67, col. 9, ll. 1–19. It would have been obvious for the “orifice” of Jarolics to have a diameter of about 1 mm because this is a suitable dimension for an outlet tube in a gas collection device. Claim 9 is rejected under 35 U.S.C. 103 as being unpatentable over Jarolics, US 4,772,454 in view of Padden et al., US 5,319,986 and in further view of Steigert, US 2004/0006956 A1. Regarding claim 9, Jarolics as modified teaches the limitations of claim 1, as explained above. Jarolics as modified differs from claim 9 because it is silent as to the filter 5 (the “filtering element”) comprising at least one of a textile or plastic material. But the filter 5 can be made of a sintered metal. See Jarolics col. 2, ll. 8–11. Also, Steigert teaches a filter material made from sinterable powders such as metal and/or plastics. See Steigert [0013]. It would have been obvious to make the filter 5 of Jarolics from the filter material of Steigert because this would merely represent the selection of a known material based on the suitability of its intended use. See MPEP 2144.07. Claims 11, 12, 18 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Jarolics, US 4,772,454. Regarding claim 11, Jarolics teaches a probe, which reads on the claimed “integrated flow regulating component.” See Jarolics Fig., col. 2, ll. 1–17. The probe comprises an outlet duct 8 (including the physical structure), which reads on the “flow regulating component.” See Jarolics Fig., col. 2, ll. 1–17. The outlet duct 8 defines an “orifice” at the left-hand end (the “first end of the flow regulating component”). Id. The probe also comprises a filter 5 (the “filtering element”) attached to the left-hand end of the outlet duct 8, and defining a cavity 7 (the “cavity”) fluidly coupled with the “orifice.” See Jarolics Fig., col. 2, ll. 1–17. While Jarolics is silent as to the filter 5 being “removably attached” to the left-hand end of the outlet duct 8, it would have been obvious for the filter 5 to be removably attached to the left-hand end of the outlet duct 8 because the reference says that the probe can either have an integral structure or can be composed of several, separable parts. Id. at col, 2, ll. 5–7. The filter 5 leads to the open space inside the outlet duct 8 (the open space reads on the “interior channel of the at least one integrated flow regulating component). See Jarolics Fig., col, 2, ll. 1–17. The filter 5 is disposed upstream with respect to the orifice because fluid being sampled flows through gas inlet 1 through the filter 5 and then through outlet duct 8. See Jarolics Fig., col. 2, ll. 1–17. The probe is capable of being removably received within an opening on a surface of a manifold, as claimed, because the probe could be inserted into a manifold. See MPEP 2114 (functional claim language that is not limited to a specific structure covers all device that are capable of performing the recited function). PNG media_image2.png 450 783 media_image2.png Greyscale Regarding claim 12, Jarolics teaches that the filter 5 (the “filtering element”) is at least partially contained within a filter compartment 4 (the “body of the at least one integrated flow regulating component”). Regarding claim 18, Jarolics teaches that the filter 5 (the “filtering element”) comprises a substantially cylindrical member, as seen in the Fig. Regarding claim 20, Jarolics teaches that the probe (the “at least one integrated flow regulating component”) comprises a metal. See Jarolics col. 1, ll. 65–67. Claim 17 is rejected under 35 U.S.C. 103 as being unpatentable over Jarolics, US 4,772,454 in view of Templeton et al., US 6,306,620 B1. Regarding claim 17, Jarolics as modified teaches the limitations of claim 1, as explained above. Jarolics as modified differs from claim 17 because it is silent as to the diameter of the “orifice” at the downstream end of the outlet duct 8. Therefore, the reference fails to provide enough information tot each the “orifice” has a diameter of 0.2 to 2 mm, as claimed. But Templeton teaches a gas collection device with a tube having a diameter of about 1 mm. See Templeton col. 16, ll. 62–67, col. 9, ll. 1–19. It would have been obvious for the “orifice” of Jarolics to have a diameter of about 1 mm because this is a suitable dimension for an outlet tube in a gas collection device. Claim 19 is rejected under 35 U.S.C. 103 as being unpatentable over Jarolics, US 4,772,454 in view of Steigert, US 2004/0006956 A1. Regarding claim 19, Jarolics as modified teaches the limitations of claim 1, as explained above. Jarolics as modified differs from claim 19 because it is silent as to the filter 5 (the “filtering element”) comprising at least one of a textile or plastic material. But the filter 5 can be made of a sintered metal. See Jarolics col. 2, ll. 8–11. Also, Steigert teaches a filter material made from sinterable powders such as metal and/or plastics. See Steigert [0013]. It would have been obvious to make the filter 5 of Jarolics from the filter material of Steigert because this would merely represent the selection of a known material based on the suitability of its intended use. See MPEP 2144.07. Response to Arguments 35 U.S.C. 112(b) Rejections The Examiner withdraws the previous 35 U.S.C. 112(b) rejections in light of the amendments. 35 U.S.C. 112(a) Rejections The Examiner withdraws the previous 35 U.S.C. 112(a) rejection of claim 16 because it is cancelled. 35 U.S.C. 102 & 103 Rejections Applicant’s arguments with respect to the pending claims 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.
