`
`DETAILED ACTION
`
`Claim Objections
`
`Claim 8 is objected to because of the following informalities:
`
`Claim 8, lines 8 and 9, replaced ", and further" with -- . --
`
`Appropriate correction is required.
`
`Claim Rejections - 35 USC § 1'02
`
`The following is a quotation of the appropriate paragraphs of pre-AIA 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 —
`(e) the invention was described in (1) an application for patent, published under section
`122(b), by another filed in the United States before the invention by the applicant for patent or
`(2) a patent granted on an application for patent by another filed in the United States before
`the invention by the applicant for patent, except that an international application filed under
`the treaty defined in section 351 (a) shall have the effects for purposes of this subsection of an
`application filed in the United States only if the international application designated the United
`States and was published under Article 21 (2) of such treaty in the English language.
`
`Claim 8 is rejected under pre—AIA 35 U.S.C. 102(e) as being anticipated by Khlat
`
`et al. (20120293253).
`
`Khlat et al. (Figs. 1 and 2) disclose a power management system comprising: a
`
`charge pump converter (12) can be read as a boost converter operative to receive a first
`
`supply voltage (battery) via line 24 and generate a boosted supply voltage having a
`
`higher voltage than the first supply voltage; and a parallel amplifier circuit (14) can be
`
`read as an envelope amplifier operative to receive an envelope signal (Vramp) and the
`
`boosted supply voltage via line 38 and generate a second supply voltage based on the
`
`envelope signal and the boosted supply voltage, wherein the envelope amplifier is

`
`operative to further receive the first supply voltage via line 30 and generate the second
`
`supply voltage based on the first supply voltage and generate the second supply
`
`voltage based on the first supply voltage or the boosted supply voltage.
