Notice of Pre-AIA or AIA Status
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 § 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.
Claim(s) 1-8 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by DE102021206870.
DE102021206870 discloses a cooling system for computer system comprising ( paragraph 14, 32) a brushless motor (paragraph 15) the brushless motor comprising a rotor ( fig 2 #22) comprising a plurality of magnetic poles ( fig 2 #46) the plurality of magnetic poles copsing at least a first magnetic pole and a second magnetic pole, whin rotor being arranged to rotate around rotor axes, a stator ( fig 2 #36), fist magnetic sensor ( fig 2 S1 ) a second magnetic sensor ( fig 2 S2), when fist magnetic sensor and second magnetic sensor being arranged statically relative to stator ( paragraph 18) wherein first magnetic pole arranged at fist angle and second magnetic pole arranged at second angle, whin an angle is defined as angle around rotor axis of rotor in plane normal to rotor axis (fig 2 paragraph 19), the poles have a 90 degree angle between them ) , wherein first magnetic sensor and second magnetic sensor being arranged with an angle difference corresponding to angle difference between first angle and second angle ( fig 2 paragraphs 18-19, sensor have a 60 degree angle between them which corresponds to the angle between pole because this angle is defined in last sentence of paragraph 19 as being less than double of the angle between poles), whin fist magnetic sensor and second magnetic sensor being configured to combine the signals output by the fist magnetic sensor and second magnetic sensor to form a combines signal whin combined signal being used for control of motor ( fig 1 #30 and fig 3 S!1,S2,S3 in light of paragraph 19) and wherein rotor and stator being able to rotate relative to each other . Subject matter claims 2 is in fig 2 #44,46, subject matter claims 3 fig 2 #344,46, subject matte claim 4 is shone fig 2 #42. Claim 5 refers to analogue magnetic sensor. Any physical sensor fist generates an analog signal that may later be converted into a digital signal for processing . In that sense Hall sensor are also analogue sensor. Claim 6 is shown in fig 1 #30, S1,S2,S3. Claim 7 is shown in fig 2 #40 and S1-S3. Claim 8 discloses same as claim 1 . It is shown that angles between sensor is chosen depending on angles between rotor poles ( paragraph 19 or paragraph 29) Is clear that angle between sensors corresponds to angle between rotor poles .
Claim Rejections - 35 USC § 103
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.
Claim(s) 9-12 are rejected under 35 U.S.C. 103 as being unpatentable over DE102021206870 in view of EP3029427.
DE102021206870 disclosed as above lacks disclosing processing of sensor signals . EP3029427 discloses processing of sensor signals such that effect of external magnetic fields are cancelled out . This is shown in paragraph 25 . It would have been obvious to one of ordinary skill in the art before the effective filing date of claimed invention to combine the brushless motor of DE102021206870 with processing of EP3029427 for improved control .
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. 20260121487 and 20180097462 disclose magnetic sensors and brushless motor .
