`
`
`
`REMARKS
`
`Serial No. 13/590,423
`
`The Office Action mailed November 14, 2013, has been received and reviewed. Claims
`
`1—20 are pending in the application. Claims 1, 7, 17 and 19 stand rejected. Claims 2—6, 8—16, 18
`
`and 20 are objected to as depending from rejected base claims. Applicant has amended claims 1,
`
`17 and 19, submits the following remarks, and respectfully requests reconsideration of the
`
`application. Support for Applicant’s claim amendments is found in at least paragraph 0057 of
`
`Applicant’s as—filed specification. No new matter has been added.
`
`35 U.S.C. § 103(a) Obviousness Rejections
`
`Obviousness Rejection Based on Eisenhut
`
`Claims 1, 7, 17 and 19 stand rejected under 35 U.S.C. § 103(a) as being unpatentable
`
`over U.S. Patent No. 7,751,513 to Eisenhut et al. (“Eisenhut”). Applicant has amended the
`
`claims and respectfully requests reconsideration of the rejection as hereinafter set forth.
`
`To establish a prima facie case of obviousness the prior art reference (or references when
`
`combined) must teach or suggest all the claim limitations. In re Royka, 490 F.2d 981, 985
`
`(CCPA 1974); see also MPEP § 2143.03. Additionally, there must be “a reason that would have
`
`prompted a person of ordinary skill in the relevant field to combine the [prior art] elements” in
`
`the manner claimed. KSR Int’l Co. v. Teleflex Inc., 127 S. Ct. 1727, 1742, 167 L.Ed.2d 705, 75
`
`USLW 4289, 82 U.S.P.Q.2d 1385 (2007). Finally, to establish a primafacie case of obviousness
`
`there must be a reasonable expectation of success. In re Merck & C0., Inc., 800 F.2d 1091, 1097
`
`(Fed. Cir. 1986). Furthermore, the reason that would have prompted the combination and the
`
`reasonable expectation of success must be found in the prior art, common knowledge, or the
`
`nature of the problem itself, and not based on the Applicants’ disclosure. DyStar Textilfarben
`
`GmbH & C0. Deutschland KG v. C. H. Patrick C0., 464 F.3d 1356, 1367 (Fed. Cir. 2006);
`
`MPEP § 2144. Underlying the obvious determination is the fact that statutorily prohibited
`
`hindsight cannot be used. KSR, 127 S.Ct. at 1742; DyStar, 464 F.3d at 1367.
`
`The 35 U.S.C. § 103(a) obviousness rejections of claims 1, 7, 17 and 19 are improper
`
`because the elements for a primafacie case of obviousness are not met. Specifically, the
`
`rejection fails to meet the criterion that the prior art reference(s) must teach or suggest a_ll the
`
`-7-
`
`
`
`Serial No. 13/590,423
`
`claims limitations.
`
`Regarding independent claims 1, 17 and 19, Applicant’s independent claims 1, l7 and
`
`19 include claim elements not taught or suggested in the cited reference. Applicant’s
`
`independent claims 1, l7 and 19 each recite, in part, a “amplify[ing] an input radio frequency
`
`(RF) signal and provide a first output RF signal ..., the first output RF signal including at least
`
`a first carrier of the multiple carriers; and
`
`amplify[ing] the input RF signal and provide a
`
`second output RF signal ..., the second output RF signal including at least a second carrier of
`
`the multiple carriers ditZerent than the first carrier.”
`
`Applicant respectfully asserts that Eisenhut does not teach or suggest Applicant’s
`
`invention as presently claimed in amended independent claims 1, l7 and 19.
`
`The Office Action concedes:
`
`Eisenhut et al. differs from the application claim in that Eisenhut et al. does not discloses
`the input RF signal comprising transmissions sent on multiple carriers at
`
`different frequencies to a wireless device as set forth in the application claim.
`(Office Action, p. 3; emphasis added)
`
`Applicant concurs.
`
`The Office Action then alleges:
`
`Because the application claim recites the signal input being an input RF signal, therefore,
`if would have been obvious for one of ordinary skill in the art at the time the
`invention was made that one recognizes Eisenhut et al. would apply to the input
`RF signal as claimed. (Office Action, p. 3)
`
`Regardless of the veracity of the above—allegation, Applicant has amended independent claims 1,
`
`l7 and 19 to recite “amplify[ing] an input radio frequency (RF) signal and provide a first output
`
`RF signal ..., the first output RF signal including at least a first carrier of the multiple
`
`carriers; and
`
`amplify[ing] the input RF signal and provide a second output RF signal ..., the
`
`second output RF signal including at least a second carrier of the multiple carriers different
`
`than the first carrier,” which is not taught in Eisenhut.
`
`In contrast, Eisenhut teaches, with respect to Fig. 1, that the output from the first
`
`amplifier in signal path 6 is combined with the output from the second amplifier in signal path 7.
`
`-8-
`
`
`
`Serial No. 13/590,423
`
`Specifically, Eisenhut teaches:
`
`The signal output 73 for the digital signal of the second signal path 7, for example, leads
`to an input of a switch 10. The switch 10 can assume one of at least two possible
`states, wherein, in a first switching state, the switch connects the output 73 to an
`input 91 of a power detector 9. In a second switching state, the switch 10
`connects the output 73 of the second signal path 7 t0 the input 81 of a
`demodulation device 8. Furthermore, the output 63 0f the first signal path 6 is
`
`also connected to the input 81 of the demodulation device 8. (Eisenhut, col. 5,
`
`lns. 35—43; emphasis added)
`
`Applicant respectfully notes that output signals 63 and 73 in Eisenhut are identical in carrier
`
`selection and are merely ‘power combined’ at the input 81.
`
`Therefore, since Eisenhut does not teach “amplify[ing] an input radio frequency (RF)
`
`signal and provide a first output RF signal ..., the first output RF signal including at least a
`
`first carrier of the multiple carriers; and
`
`amplify[ing] the input RF signal and provide a
`
`second output RF signal ..., the second output RF signal including at least a second carrier of
`
`the multiple carriers ditZerent than the first carrier” as claimed by Applicant, the cited
`
`reference cannot render obvious, under 35 U.S.C. §103, Applicant’s invention as presently
`
`claimed. Accordingly, Applicant respectfully requests the rejections of independent claims 1, 17
`
`and 19 be withdrawn.
`
`Regarding dependent claim 7, the nonobviousness of independent claim 1 precludes a
`
`rejection of claim 7 which depends therefrom because a dependent claim is obvious only if the
`
`independent claim from which it depends is obvious. See In re Fine, 5 U.S.P.Q.2d 1596, 1600
`
`(Fed. Cir. 1988), see also MPEP § 2143.03. Therefore, Applicant requests that the Examiner
`
`withdraw the 35 U.S.C. § 103(a) obviousness rejection to independent claim 1 and claim 7 which
`
`depends therefrom.
`
`Objections to Claims 2-6, 8-16, 18 and 20/Allowable Subject Matter
`
`Claims 2—6, 8—16, 18 and 20 stand objected to as being dependent upon rejected base
`
`claims, but are indicated to contain allowable subject matter and would be allowable if placed in
`
`appropriate independent form. Applicant acknowledges this indication with appreciation, but
`
`-9-
`
`
`
`respectfully asserts that the claims in their present form, along with all other claims presently
`
`under consideration, are in condition for allowance.
`
`Serial No. 13/590,423
`
`-10-
`
`
`
`Serial No. 13/590,423
`
`CONCLUSION
`
`Claims 1—20 are believed to be in condition for allowance, and an early notice thereof is
`
`respectfully solicited. Should the Examiner determine that additional issues remain which might
`
`be resolved by a telephone conference, the Examiner is respectfully invited to contact
`
`Applicant’s undersigned attorney.
