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.
Claims 1-6 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by MacLean
et al. (US 6,965,223 B1), hereinafter ‘MacLean.
In re to claim 1, MacLean disclose a load drive circuit (i.e. 200, fig. 2, see col. 3, lines 43-47) comprising: an n-channel output transistor (i.e. 236) of which the drain is connected to a power supply (i.e. VIN), and which applies an output from the source to a load (i.e. RO) when the output is ON (i.e. see col. 3, lines 48-53); and a soft start reference block (i.e. 210, see col. 3, lines 48-53) that applies a soft start voltage between the gate and the source of the output transistor (i.e. 236) in a predetermined period from when the output is started to be ON (i.e. see col. 4, lines 4-16); wherein the soft start reference block applies, between the gate and the source of the output transistor (i.e. 236), a soft start voltage corresponding to the gate-source voltage of a reference transistor (i.e. 222) through which a current from a current source is made to flow, and the size of the reference transistor is smaller than that of the output transistor (i.e. see col. 4, lines 1-35).
In re to claim 2, MacLean disclose the load drive circuit (i.e. 200, fig. 2, see col. 3, lines 43-47) according to claim 1, wherein the reference transistor has similar characteristics to the output transistor (i.e. the reference transistor 222 and the output transistor are n-channel/NMOS transistors, see fig. 2).
In re to claims 3-6, MacLean disclose the load drive circuit (i.e. 200, fig. 2, see col. 3, lines 43-47) according to claim 1, wherein the soft start reference block (i.e. 210) applies a soft start voltage between the gate and the source of the output transistor (i.e. 236) by making a current corresponding to the gate-source voltage of the reference transistor flow through a resistor arranged between the gate and the source of the output transistor (i.e. see col. 4, lines 4-35). wherein a predetermined period from when the output is started to be ON is a period until the gate-source voltage of the output transistor (i.e. 236) reaches a predetermined value after the output is ON (i.e. col. lines 42-47); further comprising a full-on control block that applies a full-on voltage between the gate and the source of the output transistor (i.e. 236) after a predetermined period has elapsed from when the output is started to be ON (i.e. see col. 4, lines 17-45); wherein the full-on control block applies a full-on voltage between the gate and the source of the output transistor (i.e. 236) by making a predetermined current flow through a resistor (i.e. RX) arranged between the gate and the source of the output transistor (i.e. 236, see fig. 2).
