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 . Claim Rejections - 35 USC § 102 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.

Regarding claim 1, Liu et al teach (Figs. 1-11) a dimension measurement apparatus, comprising: a carrier plate (210), configured to carry a to-be-measured item (400); and a line scan camera (232), disposed opposite to the carrier plate along a first direction and configured to photograph the to-be-measured item, wherein the line scan camera (232) is configured to be movable relative to the carrier plate along a second direction, and the first direction is perpendicular to the second direction. Regarding claim 2, Liu et al teach the line scan camera is configured to be movable (via 283). Regarding claim 3, Liu et al teach a plurality of the line scan cameras are disposed, and the plurality of line scan cameras comprise a first line scan camera and a second line scan camera (line scanning unit comprises 2 line scanning cameras); and the first line scan camera and the second line scan camera are arranged along a third direction (X axis), and the third direction intersects the second direction (Z axis). Regarding claim 4, Liu et al teach the to-be-measured item is an electrode assembly (10a). Regarding claim 6, Liu et al teach a shelf (336), wherein the carrier plate and the line scan camera are disposed on the shelf. Allowable Subject Matter Claims 5, and 7-21 are 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.
