Office Action

§112
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 . 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 1-7, 9-16, and 18-20 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. All of the pending independent claims have been amended to recite, “wherein the quantum gate operation and the induced rotation are performed without addressing or applying pulses to the ions adjacent to the target ions.” The applicant has not explained where support for this new negative limitation may be found. Further, upon review of the disclosure, no explicit or inherent support was found for this limitation. It is noted that the avoiding addressing or applying pulses to neighboring ions in an ion trap is not a trivial task, and many processes for mitigating and correcting for inadvertent or accidental addressing and pulse application to ions are under active research. Thus, the specification’s descriptions of addressing and applying pulses to target ions cannot be reasonably interpreted to indicate that that neighboring ions were not also subject to inadvertent or accidental addressing or pulse application. As such, the limitation is new matter, and is rejected for failing the written description requirement. 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 1-7, 9-16, and 18-20 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. All of the pending independent claims have been amended to recite, “wherein the quantum gate operation and the induced rotation are performed without addressing or applying pulses to the ions adjacent to the target ions.” There is insufficient antecedent basis for “the ions adjacent to the target ions.” As such, the claims are indefinite. Response to Arguments Applicant’s amendments have overcome the obviousness rejection of record.
