Office Action

§102 §112 §Other
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 without traverse of Group I (claims 1-13) in the reply filed on 12/18/2025 is acknowledged. 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 1-13 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. Regarding claim 1, the scope of the claims is unclear because the claims are directed to a tray yet recites structure of the tray in relation to a ceramic ball. For purposes of examination, claims will be given their broadest reasonable interpretation and will be treated as a tray capable of functioning with a ceramic ball. 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: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim(s) 1-6, 10-13 is/are rejected under 35 U.S.C. 102a1 as being anticipated by US 2005/0145533 to Seligson. Regarding claim 1, Seligson discloses a storage tray (14) capable of storing ceramic balls (44) comprising a storage portion (16) that can store the ball, wherein the storage portion has a protruding portion (A, Fig 2 below) formed such that a center of a bottom surface portion (B, Fig 2 below) of the storage portion is hollow, a height of an outer circumferential surface of the protruding portion relative to a diameter of a ceramic ball is capable of being within a range of .05 or more and .3 or less since it has the structure as recited and depending on the dimensions of the ball.
