§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 . Claim Objections Claims 1, 10 and 18 objected to because of the following informalities: Regarding claim 1, the phrase “at least one shredding roller which can rotate about an axis” should be changed to “at least one shredding roller is configured to be rotated about an axis”. Regarding claim 1, the phrase “a feed means for feeding material to be shredded to the shredding roller” should be changed to “a feed means for feeding the material to be shredded to the shredding roller”. Regarding claim 1, the phrase “shredding tools provided on the basic roller body, which are spaced apart from one another” should be changed to “shredding tools provided on the basic roller body, the shredding tools are spaced apart from one another”. Regarding claim 1, the phrase “of material to be shredded is produced” should be changed to “of the material to be shredded is produced”. Regarding claim 1, the phrase “at least one region than in another region” should be changed to “at least one region than in another region of the plurality of regions”. Regarding claim 10, the phrase “a blade which can be connected” should be changed to “a blade is configured to be connected”. Regarding claim 18, the phrase “A shredding roller for a shredding device for shredding material to be shredded, for use in the field of recycling and waste processing, with a basic roller body rotatable about an axis of rotation and with shredding tools arranged on the basic roller body at a distance from one another and in a plurality of rows” should be changed to “A shredding roller for a shredding device for shredding material to be shredded, for use in the field of recycling and waste processing, the shredding roller comprising: a basic roller body rotatable about an axis of rotation and shredding tools arranged on the basic roller body at a distance from one another, and the shredding tools arranged in a plurality of rows”. Regarding claim 18, the phrase “at least one region than in another region” should be changed to “at least one region than in another region of the plurality of regions”. 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.
