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 . Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Claim Objections Claim 1 is objected to because of the following informalities: in line 1, “an active component and (200)” should apparently read --an active component (200) and--. Appropriate correction is required. 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 1-9 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. Claim 1 recites the limitation “an inner wall of the active component resists to an outer wall of the support member” in lines 3-4. It is not clear what is meant by “resists to” in this limitation. This phrase does not appear in any other prior art references in this field that could be found by the examiner. The specification also fails to provide any guidance or suggestion as to what this could mean. Based upon the specification and the Figures, the inner wall of the active component contacts and is connected to the outer wall of the support member, but there is no explanation of what is meant by “resists to” in this limitation. The fact that the specification teaches both that these components “resist to” one another and also “connect to” one another further confuses matters. Claim 1 also recites the limitation “an outer diameter of the active component is increased or reduced along the movement of the active component” in the last two lines. It is not clear what is meant by “along the movement” in this limitation. Does this mean along the axis direction that the active component makes a straight reciprocating movement, or does it mean during the movement or based upon the movement of the active component? Claim 2 recites the limitation “an inner wall of each framework resists to the support member” in lines 4-5. Similar to claim 1, it is not clear what is meant by “resists to” in this limitation. This phrase does not appear in any other prior art references in this field that could be found by the examiner. The specification also fails to provide any guidance or suggestion as to what this could mean. Based upon the specification and the Figures, the inner wall of the frameworks contact and are connected to the the support member, but there is no explanation of what is meant by “resists to” in this limitation. Claim 3 recites the limitation "the other side" in line 4. There is insufficient antecedent basis for this limitation in the claim. Claim 3 also recites the limitation “the first inclined plane inclines in an axis direction closing to the installation part from one end away from the installation part to one end closing to the installation part” in lines 5-7. It is not clear what is meant by “closing to” (either instance) in this limitation. Does this mean “close to”? If so, this may be a relative term that would render the claim indefinite (e.g., what are the metes and bounds of “close to”?). It is also not clear what would be meant by an axis direction that is close to the installation part. Claim 5 recites the limitation "the grooves or the installation blocks that are correspondingly arranged on the installation part" in lines 5-6. There is insufficient antecedent basis for this limitation in the claim; the claim previously recites grooves or installation blocks that are arranged on the nut seat, but not that are arranged on the installation part. Claim 7 recites the limitation "the length directions" in line 4. There is insufficient antecedent basis for this limitation in the claim. Claim 8 recites the limitation “the plurality of installation grooves are in sliding fit with the plurality of auxiliary frameworks correspondingly” in lines 3-4. It is not clear what is meant by “sliding fit” in this limitation. Claim 9 recites the limitation "the other side" in line 3. There is insufficient antecedent basis for this limitation in the claim. Claims 2-9 are rejected by virtue of their dependence upon at least one rejected base claim. Subject Matter Not Currently Rejected Over Prior Art As detailed supra, it is not clear what is meant to be claimed. Accordingly, while a good-faith examination has been conducted based upon other features of the present invention, no prior art is presently able to be cited or applied against the claims as currently written. As stated in In re Steele, 305 F.2d 859, 134 USPQ 292 (CCPA 1962), a prior art rejection should not be based on considerable speculation about the meaning of terms employed in a claim or assumptions that must be made as to the scope of the claims. See also MPEP 2173.06(II).
