Office Action

§112
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 . 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 42-61 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 pre-AIA the applicant regards as the invention. Regarding Claim 42, the recitation of, “a tubular wind turbine component” in Lines 13-14 is unclear if this is the same one previously recited in Line 1. For the purposes of prior art examination, the recitation is considered to mean the same one. Applicant is suggested to amend the limitation to say, “the [[a]] tubular wind turbine component”. “in particular” in Line 42, makes the claim unclear as it is not understood if the limitation following the term is required by the claim. For purposes of prior art examination, the recitation following, “in particular” is considered optional. Regarding Claim 43, the recitation of, “in particular” in Line 33, makes the claim unclear as it is not understood if the limitation following the term is required by the claim. For purposes of prior art examination, the recitation following, “in particular” is considered optional. Regarding Claim 45, the recitation of, “in particular” in Lines 4 and 7, makes the claim unclear as it is not understood if the limitation following the term is required by the claim. For purposes of prior art examination, the recitation following, “in particular” is considered optional. Regarding Claim 46, the recitation of, “in particular” in Lines 2, 4, and 5, makes the claim unclear as it is not understood if the limitation following the term is required by the claim. For purposes of prior art examination, the recitation following, “in particular” is considered optional. Regarding Claim 47, the recitation of, “in particular” in Line 5, makes the claim unclear as it is not understood if the limitation following the term is required by the claim. For purposes of prior art examination, the recitation following, “in particular” is considered optional. Regarding Claim 56, the recitation of, “in particular” in Lines 2 and 45, makes the claim unclear as it is not understood if the limitation following the term is required by the claim. For purposes of prior art examination, the recitation following, “in particular” is considered optional. Regarding Claim 57, the recitation of, “in particular” in Line 34, makes the claim unclear as it is not understood if the limitation following the term is required by the claim. For purposes of prior art examination, the recitation following, “in particular” is considered optional. Claims 33-55 and 57-61 are also rejected by virtue of their dependency. Allowable Subject Matter Claims 42-61 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. PNG media_image1.png 327 502 media_image1.png Greyscale PNG media_image2.png 422 558 media_image2.png Greyscale Regarding Claim 42, the closest prior art is considered to be DE202021102172U1 discloses a support assembly for transporting a tubular wind turbine component. Comparing figure 2C of the instant application with the comparable support assembly of the prior art illustrated in figure 2, the primary reasons for allowance is that the prior art fails to disclose the specific configuration of the first flexible restraint, specifically, the flexible restraint path extending beyond an outer right vertical tangent of the tubular wind turbine component position to a second contact point on the outer surface where the flexible restraint extends away from the outer surface, and from a second contact point to a second fixing point, wherein the second fixing point is located to the left and below the second contact point (see figure 2C of instant application vs figure 2 of the prior art, also reproduced/annotated above). Therefore, it is not known in, nor obvious from the prior art to construct a support assembly as claimed. Regarding Claim 56, a similar discussion to that of Claim 42 applies. Claims 43-55 and 57-61 also contain allowable subject matter by virtue of their dependency. Internet/E-mail Communication In order to permit communication regarding the instant application via email, Applicant is invited to file form PTO/SB/439 (Authorization for Internet Communications) or include the following statement in a filed document or remarks of a filed response (see MPEP 502.03 Il): Recognizing that Internet communications are not secure, I hereby authorize the USPTO to communicate with the undersigned and practitioners in accordance with 37 CFR 1.33 and 37 CFR 1.34 concerning any subject matter of this application by video conferencing, instant messaging, or electronic mail.
