The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 112
The following is a quotation of the first paragraph of 35 U.S.C. 112(a):
(a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention.
The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112:
The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention.
Claims 8 and 18 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention.
Regarding claim 8, the specification does not provide adequate disclosure to perform the claimed functions of verifying that the at least two of the domain walls were annihilated based on the measured magnetization state of the multi-turn loop.
[0011] In some embodiments, the read out circuit is further configured to measure a magnetization state of the multi-turn loop, and the controller is configured to verify that the at least two of the domain walls were annihilated based on the measured magnetization state of the multi-turn loop.
[0021] In some embodiments, the method further comprises measuring a magnetization state of the multi-turn loop; and verifying that the at least two of the domain walls were annihilated based on the measured magnetization state of the multi-turn loop.
[0095] For example, the multi-turn sensor system can measure the magnetization state of each of the spirals 102 and 104 before and after re-magnetization of the portion 114 of the multi-turn spiral 100 (e.g., blocks 204 and 226). The multi-turn sensor system can verify that the multi-turn spiral 100 has been filled with domain walls prior to re-magnetization and verify that the pair of domain walls has been annihilated after re-magnetization.
The specification is silent as to the manner in which the controller implements verifying that the at least two of the domain walls were annihilated based on the measured magnetization state of the multi-turn loop. The specification fails to provide the manner in which verification takes place. The specification appears to lack any formulas, any acts of comparisons or any other actions performed for verifying.

Claim 2 is objected to because of the following informalities:
Regarding claim 2, line 3 it appears the “count in” should be -- count is --.
Appropriate correction is required.
Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 1, 2 , 10 , 11, 13, 14, 19 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Diegel et al. (CN 108369108 B) in view of Liu et al. (US 20130221949).
Regarding claim 1, Diegel et al. teach A multi-turn magnetic sensing system comprising: a multi-turn loop through which domain walls propagate in response to rotation of a magnetic field; (Note Fig. 5, spiral structure);
a magnetization component configured to provide the domain walls to the multi-turn loop; (Note domain wall generators 23 and 24, Fig. 6)
Diegel et al. does not teach one or more wires configured to annihilate at least two of the domain walls of the multi-turn loop.
Liu et al. teach one or more wires configured to annihilate at least two of the domain walls of the multi-turn loop. (By applying the reset current in sequence along series of reset lines 152, 154, 156, 158 instead of simultaneously along one long reset line, the individual reset line segment resistance can be significantly reduced. As a result, the magnitude of the reset current pulse is drastically increased given a certain reset bias voltage. The higher reset current pulse increases the reset field strength and therefore ability to remove the magnetic domain walls in the flux guide.) [par. 0043]
Therefore it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify Diegel et al. to include the teaching of one or more wires configured to annihilate at least two of the domain walls of the multi-turn loop to eliminate noise that may lower the SNR during measurements of an external field.
Regarding claims 2, Diegel et al. teach wherein the magnetization component comprises a reset wire configured to fill the multi-turn loop with domain walls. (Thus, the domain wall generator DWG23 (or DWG24) completely fills the DW spiral. [0152]) The examiner’s position is the connection between the domain wall generator and spiral is broadly interpreted as a rest wire. Also note par. [0154] The electrical connection for a helix with two DWGs is always “180° connection” (see Figure 5), and has been omitted in Figure 6 for clarity.
Regarding claim 10, Diegel et al. teach wherein the magnetization component comprises: one or more reset wires configured to generate a magnetic field having a strength sufficient to fill the multi-turn loop with the domain walls. (Thus, the domain wall generator DWG23 (or DWG24) completely fills the DW spiral. [0152]) The examiner’s position is the connection between the domain wall generator and spiral is broadly interpreted as a reset wire. Also note par. [0154] The electrical connection for a helix with two DWGs is always “180° connection” (see Figure 5), and has been omitted in Figure 6 for clarity.
Regarding claim 11, Diegel et al. teach multi-turn loop comprises a multi-turn spiral including a first spiral and a second spiral, the first spiral and the second spiral coupled together such that domain walls can propagate between the first and second spirals. (Note Fig. 8)
Regarding claim 13, Diegel et al. teach A method of initializing a multi-turn magnetic sensing system, the method comprising:
providing domain walls to a multi-turn loop; (Note domain wall generators 23 and 24, Fig. 6) and
Diegel et al. does not teach applying a magnetic field to a portion of the multi-turn loop to annihilate at least two of the domain walls of the multi-turn loop,
wherein after the applying the multi-turn loop is configured to change state in response to rotation of a magnetic field.
Liu et al. teach applying a magnetic field to a portion of the multi-turn loop to annihilate at least two of the domain walls of the multi-turn loop. (By applying the reset current in sequence along series of reset lines 152, 154, 156, 158 instead of simultaneously along one long reset line, the individual reset line segment resistance can be significantly reduced. As a result, the magnitude of the reset current pulse is drastically increased given a certain reset bias voltage. The higher reset current pulse increases the reset field strength and therefore ability to remove the magnetic domain walls in the flux guide.) [par. 0043] and
wherein after the applying the multi-turn loop is configured to change state in response to rotation of a magnetic field. ([0050] During measurement, a lower current pulse may be applied simultaneously through the switches 711, 721, 724, 726 and 718 to stabilize the sensors 122.) The Examiner’s position is that the state is changed from unstabilized to stabilized.
Therefore it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify Diegel et al. to include the teaching of applying a magnetic field to a portion of the multi-turn loop to annihilate at least two of the domain walls of the multi-turn loop, wherein after the applying the multi-turn loop is configured to change state in response to rotation of a magnetic field eliminate noise that may lower the SNR during measurements of an external field.
Regarding claim 14, Diegel et al. teach wherein the applying is performed using a coil that wraps around a portion of the multi-turn loop. ([0163] Figure 10 schematically illustrates the configuration of a sensor element according to the invention for counting 40 revolutions (U) in an exemplary application. The sensor element includes rings with coprime maximum rotation speeds of 5 (S5), 8 (S8), and 9 (S9). The top view shows a square spiral as exemplarily shown in Figure 7, which is illustrated here in a space-saving manner. The rings, DW locations, and domain walls are symbolically shown as in Figure 3d. For redundant rotation counting, rings S5 and S8 are needed, and their combination can count up to 40 rotations: 5U * 8U = 40U. By adding ring S9 for redundant rotation counting, there are three combinations of two rings each, which can count at least 40 rotations. ).
Regarding claim 19, Diegel et al. teach wherein the providing the domain walls to the multi-turn loop is performed using one or more reset wires that generate a magnetic field having a strength sufficient to fill the multi-turn loop with the domain walls. (Thus, the domain wall generator DWG23 (or DWG24) completely fills the DW spiral. [0152]) The examiner’s position is the connection between the domain wall generator and spiral is broadly interpreted as a reset wire. Also note par. [0154] The electrical connection for a helix with two DWGs is always “180° connection” (see Figure 5), and has been omitted in Figure 6 for clarity.
Regarding claim 20, Diegel et al. teach a multi-turn loop through which domain walls propagate in response to rotation of a magnetic field; (Note Fig. 5, spiral structure ); and
a decoder configured to output a turn count that is based on output signals from the multi-turn loop. (In other words, the analysis and processing electronic device outputs the following as the counted rotations [0056]
Diegel et al. does not teach means for annihilating at least two of the domain walls of the multi-turn loop
Liu et al. teach one or more wires configured to annihilate at least two of the domain walls of the multi-turn loop. (By applying the reset current in sequence along series of reset lines 152, 154, 156, 158 instead of simultaneously along one long reset line, the individual reset line segment resistance can be significantly reduced. As a result, the magnitude of the reset current pulse is drastically increased given a certain reset bias voltage. The higher reset current pulse increases the reset field strength and therefore ability to remove the magnetic domain walls in the flux guide.) [par. 0043]
Therefore it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify Diegel et al. to include the teaching of one or more wires configured to annihilate at least two of the domain walls of the multi-turn loop eliminate noise that may lower the SNR during measurements of an external field.

and a controller (processing circuit 906, par. 0063 ) configured to apply a current pulse to the one or more wires with a direction of the current pulse based on the measured external magnetic field. ([0043] The direction in which the current is applied depends on the direction of an external magnetic field, typically the magnetic field generated by the magnet that the sensor will measure.)
Therefore it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify Diegel et al. to include the teaching of a read out circuit configured to measure a direction of an external magnetic field; and a controller configured to apply a current pulse to the one or more wires with a direction of the current pulse based on the measured external magnetic field so that the spiral can be initialized very quickly by applying a current to the conductor in the right direction.

These domain walls can then be injected into the magnetic strip 200. As the magnetic domain changes, the resistance of the GMR elements 202 will also change due to the resulting change in magnetic alignment.)[par. 0031]

Examiner’s position is that domain wall is deleted is interpreted as annihilation and as a gap being present in addition to the determining (counting several revolutions).
Therefore it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify Diegel et al. to include the teaching of a decoder configured to output a turn count that is based on output signals from the multi-turn loop, wherein the decoder is configured to determine the turn count in based on a location of a domain wall gap formed by the annihilation of the at least two of the domain walls to provide a linear measuring device. (Note Schneider et al. par. 0016)
Examiner’s Note:
