DETAILED ACTION
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 .
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.
Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 1-20 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Regarding Claim 1 (similarly in Claim 19 & 20), the applicant recites “wherein, in a process of inserting the oil pipe into the rotating shaft body from either of the first hole and the second hole, the oil pipe is configured to form an interference fit with the one used as a non-inserting hole in the first hole and the second hole first, and then to form an interference fit with the other one used as an inserting hole in the first hole and the second hole.” The claim appears to be mainly regarded to an apparatus (motor rotating shaft). Then the claim recites a method step (process of inserting). Is the claim regarded to an apparatus or a method step? The scope appears to be unclear.
Moreover, the applicant recites “wherein, in a process of inserting the oil pipe into the rotating shaft body from either of the first hole and the second hole, the oil pipe is configured to form an interference fit with the one used as a non-inserting hole in the first hole and the second hole first, and then to form an interference fit with the other one used as an inserting hole in the first hole and the second hole”. The inserting of the oil pipe appears optional as “either the first hole or second hole”. Moreover, the non-inserting hole is also unclear if the inserting hole appears optional to either the first or second hole. What is the inserting hole and what is the non-inserting hole?
Therefore, the claim is vague and indefinite.
Claims 2-18 are rejected based on the dependency from Claim 1.
