Further, Berliner teaches:
A projecting device comprising a motor driven wheel and a switch operable in a first position that rotates the driven wheel in one direction and a second position that rotates the driven wheel in a second opposite direction (rotatable discs/wheels 74/76 rotated via motor 70 in two opposite directions based on the position of switch 82, Fig. 5, 10-11, Col. 4 lines 12-44).
It would have been obvious to one having ordinary skill in the art to have modified the invention of Wagner to have formed the actuator movable to a second opposite position to rotate the motor and wheels in a second direction in order to vary the spin applied to the projectile/string as is known in the art and as taught by Berliner (Col. 4 lines 12-44).
In Reference to Claim 5
Wagner as modified by Gillespie and Berliner teaches:
The device of claim 4, wherein the string comprises a looped string, and wherein in response to the driven wheel being driven in the second direction, the looped string is retrieved into the cavity (with the driven wheel rotating the second opposite direction, the string 10 is moved into the housing cavity through the aperture 180 as modified).
In Reference to Claim 6
Wagner as modified by Gillespie teaches:
The device of claim 3, wherein the pair of wheels are configured to propel a looped string away from the device in response to the driven wheel rotating in a first direction (Wagner: switch S is movable into a position to activate the motor to drive the looped string 10 in a first direction out of exit aperture 180 and into the air, Fig. 1-3).
Wagner fails to teach:
Wherein the driven wheel ceases to be driven in a first direction, and begins to be driven in a second direction, opposite the first direction to retrieve the looped string into the cavity.
Further, Berliner teaches:
A projecting device comprising a motor driven wheel and a switch operable in a first position that rotates the driven wheel in one direction and a second position that rotates the driven wheel in a second opposite direction (rotatable discs/wheels 74/76 rotated via motor 70 in two opposite directions based on the position of switch 82, Fig. 5, 10-11, Col. 4 lines 12-44).
It would have been obvious to one having ordinary skill in the art to have modified the invention of Wagner to have formed the actuator movable to a second opposite position to rotate the motor and wheels in a second direction in order to vary the spin applied to the projectile/string as is known in the art and as taught by Berliner (Col. 4 lines 12-44).
In Reference to Claim 17
Wagner as modified by Gillespie teaches:
The device of claim 16, wherein the pair of wheels are configured to propel a looped string through the exit aperture away from the device in response to the driven wheel rotating in the first direction (Wagner: switch S is movable into a position to activate the motor to drive the looped string 10 in a first direction out of exit aperture 180 and into the air, Fig. 1-3).
Wagner fails to teach:
Wherein in response to further actuation of the actuator, the driven wheel ceases to be driven in a first direction, and begins to be driven in a second direction, opposite the first direction.
Further, Berliner teaches:
A projecting device comprising a motor driven wheel and a switch operable in a first position that rotates the driven wheel in one direction and a second position that rotates the driven wheel in a second opposite direction (rotatable discs/wheels 74/76 rotated via motor 70 in two opposite directions based on the position of switch 82, Fig. 5, 10-11, Col. 4 lines 12-44).
It would have been obvious to one having ordinary skill in the art to have modified the invention of Wagner to have formed the actuator movable to a second opposite position to rotate the motor and wheels in a second direction in order to vary the spin applied to the projectile/string as is known in the art and as taught by Berliner (Col. 4 lines 12-44).
Claims 7 and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Wagner, Gillespie, and Berliner as applied to claim 6/17 above, and further in view of Rizzo et al. US Pub. No. 2013/0104870.
In Reference to Claim 7
Wagner as modified by Gillespie and Berliner teaches:
The device of claim 6, wherein the driven wheel of the pair of wheels rotates in the first direction in response to a first interaction with the actuator (the switch S of Warner in the first position rotates the driven wheel and string in the first direction) and the driven wheel of the pair of wheels rotates in the second direction for an amount of time in response to a second interaction with the actuator (as modified by Berliner, the switch is movable to a second position to rotate the driven wheel and string in the second direction for a user determined amount of time).
Wagner fails to teach:
Wherein the driven wheel of the pair of wheels rotates in the second direction for a predetermined amount of time beginning when the actuator is moved to the second position.
Further, Rizzo teaches:
A projecting device having motor driven rotating wheels to project an object from the device, the wheels operable to reverse operation for a predetermined period of time and capable of sensing a predetermined threshold of torque/current ([0048]).
It would have been obvious to one having ordinary skill in the art to have modified the invention of Wagner to have allowed the wheels to reverse direction for a period of time and sense a predetermined threshold of torque/current applied to the motor during use in order to allow a jam to be undone during use or prevent failure or damage to the motor during use as taught by Rizzo ([0048]).
In Reference to Claim 18

Wagner fails to teach:
Wherein the driven wheel of the pair of wheels rotates in the second direction for a predetermined amount of time beginning when the actuator is moved to the second position.
Further, Rizzo teaches:
A projecting device having motor driven rotating wheels to project an object from the device, the wheels operable to reverse operation for a predetermined period of time and capable of sensing a predetermined threshold of torque/current ([0048]).
It would have been obvious to one having ordinary skill in the art to have modified the invention of Wagner to have allowed the wheels to reverse direction for a period of time and sense a predetermined threshold of torque/current applied to the motor during use in order to allow a jam to be undone during use or prevent failure or damage to the motor during use as taught by Rizzo ([0048]).
Claims 13-15 are rejected under 35 U.S.C. 103 as being unpatentable over Wagner and Gillespie as applied to claim 12 above, and further in view of Bourdelaise et al. US Pat. No. 8,876,574.
In Reference to Claim 13
Wagner as modified by Gillespie teaches:
The device of claim 12 as rejected above.
Wagner fails to teach:
Wherein the extension member is hingedly attached to the body at a hinge.
Further, Bourdelaise teaches:
A projecting device (300) comprising a body (302) and an extension (400a/b) contacting a user’s hand and pivotal relative the body against a biasing spring (338, Fig. 3a-10e).
It would have been obvious to one having ordinary skill in the art to have modified the invention of Wagner to have formed the extension with a pivotal hinged extension in order to make it easier for a user to actuate or trigger or to hold more comfortably within a user’s hand and as this type of trigger/activation is known and used in the art as taught by Bourdelaise (Col. 1 lines 34-62, Col. 8 line 64 – Col. 9 lines 24).
In Reference to Claim 14
Wagner as modified by Gillespie and Bourdelaise teaches:
The device of claim 13, wherein the extension member is biased about the hinge toward a side of the body opposite a side of the body on which the pair of wheels are attached (body 302 hinged against 400a/b which pivots against bias spring 338 at an end opposite the top/wheel end of the body of Wagner as modified).
In Reference to Claim 15
Wagner as modified by Gillespie and Bourdelaise teaches:
The device of claim 14, wherein the extension member is configured to align with a palm of a user in response to the device being attached to an inside of the wrist of the user with the at least one strap, and wherein the extension member is biased into the palm of the user (the strap of Gillespie allows the user to grip the extension of Wagner with the palm of the hand during use, which is pivotal against the spring bias of Bourdelaise as modified above).
Allowable Subject Matter
Claims 9 and 19 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
The following is a statement of reasons for the indication of allowable subject matter: in addition to the other claim limitations, the specific limitations of a threading boss extending from the body, wherein the pair of wheels are disposed at a first end of the body, and wherein the threading boss extends from the first end of the body is not anticipated by or found obvious by the cited prior art.
