`
`Notice of Pre-AlA or AIA Status
`
`The present application,filed on or after March 16, 2013, is being examined under the first
`
`inventorto file provisions of the AIA.
`
`Claim Rejections - 35 USC § 102
`
`The following is a quotation of the appropriate paragraphsof 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)}(2} the claimed invention was described in a patent issued under section 151, orinanapplication
`for patent published or deemed published under s ection 122(b), in which the patent or application, as
`the case maybe, names another inventor and was effectively filed before the effectivefiling date of
`the claimed invention.
`
`Claims 1-5 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Murty US Patent No.:
`
`4,544,868.
`
`Regarding claims 1 and 4, Murty teaches, a controlcircuit (col.1, lines 4-6, motor
`
`controller) for an electric tool, the electric tool comprising a permanent magnet synchronous
`
`motor (motor 18, figure 1), a plurality of switching elements (power transistors 20, 22, 24, 26,
`
`28 and 30, figure 1), and a PWMinverter circuit (ful-wave bridge inverter 18, figure 1) that
`
`drives the permanent magnet synchronous motor, wherein the control circuit comprises a
`
`current detector (shunt resistor 96, figure 1) that detects a current flowing through the PWM
`
`inverter circuit (col.3, lines 45-50), and wherein, when braking the permanent magnet
`
`synchronous motor, the control circuitlimits a current flowing (ai. 7 ines 25-56 element OC
`
`line current reference level, fig. § A, 68} through the permanent magnet synchronous motor
`
`(fg. 6B elementia phase currentin winding A} and the PWMinverter circuit, toa
`
`predetermined currentlimit value {ca!. 7 tines 25-56, ig. SAand 6B element iref}.

`
`Regarding claim 2, Murty teaches, the control circuit for the electric tool as
`
`claimed in claim 1, wherein the PWM inverter circuit is provided between the permanent
`
`magnet synchronous motor and a battery (battery 16, see figure 1, where the PWM
`
`inverter is between the motor and the battery), and wherein the control circuit boosts
`
`an induced electromotive voltage of the permanent magnet synchronous motor by
`
`switching low-side switching elements or high-side switching elements of the PWM
`
`inverter circuit during braking of the permanent magnet synchronous motor, and
`
`regenerates a regenerative current to the battery (figure 6, col.7, lines 25-26).
`
`Regarding claim 3, Murty teaches, the control circuit for the electric tool as
`
`claimed in claim 1, wherein the control circuit changes the current limit value according
`
`to an operation modeof the electric tool (col. 8, lines 13-30).
`
`Regarding claim 5, Murty teaches, An electric tool comprising a battery
`
`(battery 16, figure 1) , a permanent magnet synchronous motor (motor 18, figure 1), a
`
`plurality of switching elements (power transistors 20, 22, 24, 26, 28 and 30, figure 1), and
`
`a PWMinverter circuit (full-wave bridge inverter 18, figure 1) that drives the permanent
`
`magnet synchronous motor, wherein the electric tool comprises a control circuit (col.1,
`
`lines 4-6, motor controller) for the electric tool, wherein the control circuit comprises a
`
`current detector (shunt resistor 96, figure 1) that detects a current flowing through the
`
`PWM inverter circuit (col.3, lines 45-50), and wherein, when braking the permanent
`
`magnet synchronous motor, the control circuit limits a current flowing (est. 7 ines 25-86
`
`glement DC line current reference level, fig. 6 4,68) through the permanent magnet
`
`synchronous motor and the PWM inverter circuit (fig. 6B slement la phase current
