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 .
Allowable Subject Matter
Claim 2, 5-8, 13, 17 objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
The following is an examiner’s statement of reasons for allowance:
Regarding claims 2 and 13, the idea of disc assemblies with housings to support two independently rotating discs is known in the art. For example, Ruckle presents a design with two independently rotating agricultural discs. Although the rejection presented herein is technical in nature, Ruckle clearly discloses two discs that rotate independently and have many of the same specifically claimed structures. However, neither this reference, nor any other reference, teaches the independently rotatable shafts being coaxial. In view of the prior art of record, any obvious combination to modify Ruckle to make the shafts coaxial as currently claimed would both require improper hindsight reasoning and render the prior art unsatisfactory for its intended purpose. For these reasons, the claims are allowable.
Regarding claims 5 and 17, Ruckle presents a design with two independently rotating agricultural discs as stated before. Although the rejection presented herein is technical in nature, Ruckle clearly discloses two discs that rotate independently and have many of the same specifically claimed structures. However, neither this reference, nor any other reference, teaches end caps as currently claimed. In view of the prior art of record, any obvious combination to modify Ruckle to include end caps as currently claimed would require improper hindsight reasoning. For these reasons, the claims are allowable.
Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.”
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 20 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.
It is unclear how claim 20 further limits the claimed invention. The claim has been examined as best understood.
Claim Rejections - 35 USC § 102
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.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
