`
`DETAILED ACTION
`
`Information Disclosure Statement
`
`The information disclosure statement filed 02/22/2011 fails to comply with 37
`
`CFR 1.98(a)(2), which requires a legible copy of each cited foreign patent document;
`
`each non-patent literature publication or that portion which caused it to be listed; and all
`
`other information or that portion which caused it to be listed.
`
`It has been placed in the
`
`application file, but the information referred to therein has not been considered.
`
`In this
`
`case, the Japanese Office Action was not considered because no English translation
`
`was filed.
`
`Claim Rejections - 35 USC § 112
`
`The following is a quotation of 35 U.S.C. 112(b):
`
`CONCLUSION—The specification shall conclude with one or more claims
`(B)
`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.
`
`Claim 2 is 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 pre-AIA the applicant regards
`
`as the invention.
`
`Claim 2 recites, “wherein the non-azeotropic mixed refrigerants include a
`
`refrigerant having a satisfactory solubility in the oil and a high boiling point as compared
`
`

`

`Application/Control Number: 12/300,706
`
`Page 3
`
`Art Unit: 3744
`
`with at least another refrigerant," which renders the claim indefinite because it is not
`
`clear what the satisfactory solubility in the oil entails, and how it can be compared with
`
`another refrigerant in the mixture. As best understood, there must be a refrigerant that
`
`has a different boiling point and solubility than that of another refrigerant in the non-
`
`azeotropic refrigerant mixture - which is inherent to a non-azeotropic refrigerant mixture.
`
`Claim Rejections - 35 USC § 103
`
`The following is a quotation of 35 U.S.C. 103(a) which forms the basis for all
`
`obviousness rejections set forth in this Office action:
`
`(a) A patent may not be obtained though the invention is not identically disclosed or described as set
`forth in section 102 of this title, if the differences between the subject matter sought to be patented and
`the prior art are such that the subject matter as a whole would have been obvious at the time the
`invention was made to a person having ordinary skill in the art to which said subject matter pertains.
`Patentability shall not be negatived by the manner in which the invention was made.
`
`The factual
`
`inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148
`
`USPQ 459 (1966),
`
`that are applied for establishing a background for determining
`
`obviousness under 35 U.S.C. 103(a) are summarized as follows:
`
`1.
`2.
`3.
`4.
`
`Determining the scope and contents of the prior art.
`Ascertaining the differences between the prior art and the claims at issue.
`Resolving the level of ordinary skill in the pertinent art.
`Considering objective evidence present
`in
`the application indicating
`obviousness or nonobviousness.
`
`Claims 1 and 2 are rejected under 35 U.S.C. 103(a) as being unpatentable over
`
`Takemasa et al. (US Pat. No. 4,788,829, herein referred to as "Takemasa"), in view of
`
`Hashizume (US Pat. No. 4,777,805).
`
`

`

`Application/Control Number: 12/300,706

`
`Art Unit: 3744
`
`Regarding claim 1, Figure 1 of Takemasa clearly discloses a refrigeration
`
`apparatus (also, see title and abstract) comprising a high-temperature-side refrigerant
`
`circuit
`
`(2) and a low-temperature-side refrigerant circuit
`
`(3) each constituting an
`
`independent refrigerant closed circuit (see fig. 1) in which a refrigerant discharged from
`
`a compressor (4, 10) is condensed (8, 23A, 23B) and then evaporated (14A, 14B, 32,
`
`42, 44, 47) to exert a cooling function (implicit), the low-temperature-side refrigerant
`
`circuit (3) having the compressor (10), a condenser (23A, 238), an evaporator (47), and
`
`a plurality of intermediate heat exchangers (32, 42, 44) and a plurality of pressure
`
`reducing units (36, 40, 46) connected in series so that the refrigerant fed back from the
`
`evaporator (47) circulates (implicit), wherein a plurality of types refrigerants (R-12,
`
`R13B1, R-14, etc) (see col. 6, lns. 4-17) are introduced, a condensed refrigerant in the
`
`refrigerants passed through the condenser (23A, 23B) is allowed to join the intermediate
`
`heat exchangers (32, 42, 44) through the pressure reducing units (36, 40, 46), a non-
`
`condensed refrigerant in the refrigerants is cooled by the intermediate heat exchangers
`
`(32, 42, 44) to successively condense the refrigerant having a lower boiling point (col. 6,
`
`ln. 46-col. 7, In. 24), the refrigerant having the lowest boiling point is allowed to flow into
`
`the evaporator through the final stage of the pressure reducing units (46), an evaporator
`
`of the high-temperature-side refrigerant
`
`(14A, 14B) and the condenser of the low-
`
`temperature-side refrigerant circuit (23A, 23B) constitutes a cascade heat exchanger
`
`(col. 6,
`
`lns. 30-32), and the evaporator (47) of the low-temperature-side refrigerant
`
`circuit is configured to obtain an extremely low temperature (-140 C) (col. 7, lns. 17-24).
`
`

`

`Application/Control Number: 12/300,706
`
`Page 5
`
`Art Unit: 3744
`
`Takemasa discloses the claimed invention, except that the plurality of cascading
`
`mixed refrigerants (i.e. R-12, R1381, R-14, etc)
`
`(see col. 6,
`
`lns. 4-17) are non-
`
`azeotropic mixed refrigerants.
`
`Hashizume, however, discloses a cascade refrigeration system that uses non-
`
`azeotropic mixed refrigerants (see col. 1,
`
`lns. 48-59). Therefore it would have been
`
`obvious to one of ordinary skill
`
`in the art at the time the invention was made to modify
`
`the plurality of cascading mixed refrigerants (see col. 6, lns. 4-17) of Takemasa to be
`
`non-azeotropic mixed refrigerants, as taught by Hashizume,
`
`for
`
`the purpose of
`
`suppressing irreversible energy losses (see col. 1, lns. 58-59).
`
`Regarding claim 2, Takemasa, as modified, discloses the claimed invention.
`
`Hashizume further discloses the non-azeotropic refrigerant mixture to include a
`
`refrigerant that has a different boiling point and solubility than that of another refrigerant
`
`in the non-azeotropic refrigerant mixture (inherent).
