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 .
Election/Restrictions
Applicant's election with traverse of the restriction requirement in the reply filed on 9 September 2025 is acknowledged. The traversal is on the ground(s) that examining these groups of claims together would not impose a serious burden. These groups fall within the same field of search and would likely draw from the same body of prior art. This is not found persuasive. As noted previously, (see paragraph 4 of the requirement) the groups of inventions do not relate to a single general inventive concept under PCT Rule 13.1 because, under PCT Rule 13.2, they lack the same or corresponding special technical features.
The requirement is still deemed proper and is therefore made FINAL.
Claims 14-20 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected invention, there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on 9 September 2025.
Drawings
The drawings are objected to because Figs. 1-2 and 8 fail to comply with 37 CFR 1.84(m) as they contain solid black shading.
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.
Claim 4 is 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 4 recites a narrow range “preferably 5kN” within a broader range “between 4kN and 6kN”. Since it is not clear if the narrow range is a limitation, the boundaries of the claim are not discernible.
Allowable Subject Matter
Claims 1-3, 5-13 are allowed.
The following is a statement of reasons for the indication of allowable subject matter: Regarding claim 1, the prior art fails to disclose or suggest a drawbar arrangement for a dolly including an adjustable drawbar comprising a front coupling element arranged to be adjusted vertically with respect to a ground plane by a control unit, wherein the control unit is arranged to determine a vertical coupling load associated with the front coupling element, and wherein the control unit is arranged to set a desired vertical coupling load associated with the front coupling element by vertically adjusting the front coupling element when coupled to a towing vehicle unit.
