§101 §102 §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 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 appl icant regards as his invention. Claims 1-3 , 5- 8, 10 , and 12-18 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. Claim 1 recites “a closed pressurized unit” and “at least one closed pressurized unit”, it is unclear if these are the same or different units, based on the previous claims both referring to them as (1) they are considered to be the same. Claim s 10-15 recite multiple instances of “ a negative response ” and “ a positive response ” however claim 9 already recites a negative response and a positive response , making it unclear if these are new or different responses. For the purposes of examining they are considered to be different. Claim 16 recites “ the air flow inducer ” , t here is insufficient antecedent basis for this limitation in the claim. Claims 2-3, 5-8, 10, and 17-18 are rejected based on their inherited deficiencies. Claim Rejections - 35 USC § 101 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claims 1-3 and 5-19 are rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more. Under step 1, claim 1 belongs to a statutory category. Under Step 2A prong 1, the claims as a whole are identified as being directed to a judicial exception as claim 1 recite(s) “ analyzing a change or deviation of sound variables within a closed pressurized unit ” and “ compare them to the stored values in the database ” which are directed to mathematical concepts and/or mental processes per applicant’s specification, for example see page 11 and 13 . Under Step 2A prong 2, evaluating whether the claim as a whole integrates the exception into a practical application of that exception, the judicial exception is not integrated into a practical application because “a s ystem for monitoring ”, “ which system is a system for distribution of gaseous components and comprises; at least one closed pressurized unit, which closed pressurized unit comprises a flow inducer, at least one device having at least one changeable open area , and at least one sound capturing device” , “ a second sound capturing device ” , and “ wherein the first and second sound capturing devices are provided on different sides of the at least one device ” are considered to be generally linking the use of a judicial exception to a particular technological environment or field of use. The elements of “ a system monitoring device having a database including stored reference values for sound variables, and values of characteristic variables associated with the gaseous components in the system and/or the changeable open area corresponding to the stored reference values for sound variables ” are considered to be generically recited computer elements do not add a meaningful limitation to the abstract idea because they amount to simply implementing the abstract idea on a computer. The elements of “ which system monitoring device is able to receive values of sound variables and characteristic variables ” are considered to be data gathering steps required to use the correlation do not add a meaningful limitation to the method as they are insignificant extra-solution activity. Under Step 2 B , evaluating additional elements to determine whether they amount to an inventive concept both individually and in combination, the claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because “a s ystem for monitoring ”, “ which system is a system for distribution of gaseous components and comprises; at least one closed pressurized unit, which closed pressurized unit comprises a flow inducer, at least one device having at least one changeable open area , and at least one sound capturing device”, “ a second sound capturing device ” , and “ wherein the first and second sound capturing devices are provided on different sides of the at least one device ” are considered to be merely indicating a field of use or technological environment in which to apply a judicial exception do not amount to significantly more than the exception itself per MPEP 2106.05(h) and are well-understood, routine, and conventional activities/elements previously known to the industry per MPEP 2106.05(d) (see prior art of record) . The elements “ a system monitoring device having a database including stored reference values for sound variables, and values of characteristic variables associated with the gaseous components in the system and/or the changeable open area corresponding to the stored reference values for sound variables ” are well-understood, routine, conventional computer functions as recognized by the court decisions listed in MPEP § 2106.05(d) . The elements of “ which system monitoring device is able to receive values of sound variables and characteristic variables ” are considered to be adding insignificant extra-solution activity to the judicial exception per MPEP 2106.05(g) and are well-understood, routine, conventional activities/elements previously known to the industry per MPEP 2106.05(d)( see prior art of record ). Claims 2-3 and 5-8 are not integrated into a practical application and not include additional elements that are sufficient to amount to significantly more than the judicial exception because they are considered to be generally linking the use of a judicial exception to a particular technological environment or field of use and merely indicating a field of use or technological environment in which to apply a judicial exception do not amount to significantly more than the exception itself per MPEP 2106.05(h) and are well-understood, routine, and conventional activities/elements previously known to the industry per MPEP 2106.05(d) (see prior art of record). Under step 1, claim 9 belongs to a statutory category . Under Step 2A prong 1, the claims as a whole are identified as being directed to a judicial exception as claim 9 recite(s) “ analyzing a change or deviation of sound variables in a system ” and “ iv. returning, by the database , a positive response to the system monitoring device in response to the detected sound variables correspond to stored reference values of sound variables and a negative response in response to the detected sound variables deviating from the stored reference values of sound variables in the database ” which are directed to mathematical concepts and/or mental processes per applicant’s specification, for example see page 11 and 13 . Under Step 2A prong 2, evaluating whether the claim as a whole integrates the exception into a practical application of that exception, the judicial exception is not integrated into a practical application because “a method for monitoring ” and “ the method comprising i. detecting, by the sound capturing device sound variables in the closed pressurized unit ii. emitting, by the sound capturing device, the detected sound variables to the system monitoring device iii. receiving, by the system monitoring device, the detected sound variables and comparing them to the stored reference values of sound variables in the database ” are considered to be data gathering steps required to use the correlation do not add a meaningful limitation to the method as they are insignificant extra-solution activity. The elements of “ which system comprises: at least one closed pressurized unit which closed pressurized unit comprises a flow inducer at least one device having a changeable open area and at least one sound capturing device ” are considered to be generally linking the use of a judicial exception to a particular technological environment or field of use. The elements of “ a system monitoring device having a database including stored reference values of sound variables, values of characteristic variables and/or the changeable open area corresponding to the stored reference values of sound variables ” are considered to be generically recited computer elements do not add a meaningful limitation to the abstract idea because they amount to simply implementing the abstract idea on a computer. Under Step 2B, evaluating additional elements to determine whether they amount to an inventive concept both individually and in combination, the claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because “a method for monitoring ” and “ the method comprising i. detecting, by the sound capturing device sound variables in the closed pressurized unit ii. emitting, by the sound capturing device, the detected sound variables to the system monitoring device iii. receiving, by the system monitoring device, the detected sound variables and comparing them to the stored reference values of sound variables in the database ” are considered to be adding insignificant extra-solution activity to the judicial exception per MPEP 2106.05(g) and are well-understood, routine, conventional activities/elements previously known to the industry per MPEP 2106.05(d)( see prior art of record ). The elements of , “ which system comprises: at least one closed pressurized unit which closed pressurized unit comprises a flow inducer at least one device having a changeable open area and at least one sound capturing device ” are considered to be merely indicating a field of use or technological environment in which to apply a judicial exception do not amount to significantly more than the exception itself per MPEP 2106.05(h) and are well-understood, routine, and conventional activities/elements previously known to the industry per MPEP 2106.05(d) (see prior art of record) . The elements of “ a system monitoring device having a database including stored reference values of sound variables, values of characteristic variables and/or the changeable open area corresponding to the stored reference values of sound variables ” are well-understood, routine, conventional computer functions as recognized by the court decisions listed in MPEP § 2106.05(d) . Claims 10, and 12-13, are considered to further describe the abstract ideas cited above. Claims 11, 14-15, 17 and 19 are considered to further describe the abstract ideas cited above; and are not integrated into a practical application and not include additional elements that are sufficient to amount to significantly more than the judicial exception because they are considered to be data gathering steps required to use the correlation do not add a meaningful limitation to the method as they are insignificant extra-solution activity and are considered to be adding insignificant extra-solution activity to the judicial exception per MPEP 2106.05(g) and are well-understood, routine, conventional activities/elements previously known to the industry per MPEP 2106.05(d)( see prior art of record ). Claims 16, 18 are not integrated into a practical application and not include additional elements that are sufficient to amount to significantly more than the judicial exception because they are considered to be generally linking the use of a judicial exception to a particular technological environment or field of use and merely indicating a field of use or technological environment in which to apply a judicial exception do not amount to significantly more than the exception itself per MPEP 2106.05(h) and are well-understood, routine, and conventional activities/elements previously known to the industry per MPEP 2106.05(d) (see prior art of record ). 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.
