Office Action

§102
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 . Response to Amendment The amendment filed on 02/06/2026 has been entered. Election/Restrictions Applicant's election with traverse of Species A, claims 1, 3-5 and 13-20 and 22 in the reply filed on 02/06/2026 is acknowledged. The traversal is on the ground(s) that Lee KR 101224194B1 does not disclose the special technical feature of amended claim 1. This is not found persuasive because new reference Jian CN 113741112A discloses the special technical feature of amended claim 1. For example, Jian CN 113741112A discloses an electronic ink screen, in at least figs.11, 12, 2 and 4-8 (figs.11 and 12 can have the embodiment shown in figs.2 and 4-8): a first conductive substrate (1204) comprising a drive layer (it’s inherent to have a drive layer, see fig.5) and an electrode layer (at least 504-509, see figs.5 and 12); a second conductive substrate (1206) located above the first conductive substrate (see figs.5 and 12); an ink display layer (1205, or a layer with 501-503 and 405) located between the first conductive substrate and the second conductive substrate (see figs.5 and 12), wherein the ink display layer has a plurality of ink accommodating cavities (501-503) that are mutually independent (see fig.5), wherein each of the ink accommodating cavities are respectively provided with ink particles (405) that have a same color such that each ink accommodating cavity includes only one color of ink particles (see figs.5 and 12), and wherein the ink particles are configured to displaying a first color (see figs.5 and 12); and a function layer (1201-1203) located at a side of the ink display layer (see fig.12), wherein the side of the ink display layer faces away from the second conductive substrate (see fig.12), and wherein the function layer is configured to display a second color (see fig.12), wherein the electrode layer comprises at least one electrode group (504-505, 506-507, or 508-509), and each ink accommodating cavity corresponds to one electrode group, wherein the electrode group comprises a first electrode (504, 506 or 508) and a second electrode (505, 507 or 509) disposed relative to each other in a thickness direction perpendicular to the electronic ink screen (see figs.5 and 12), wherein the drive layer is configured to provide a voltage to the electrode layer, to form an electric field in a vertical direction between the electrode layer and the second conductive substrate (see first left cavity, fig.5), and to form an electric field in a horizontal direction between the first electrode and the second electrode (see middle cavity, see fig.5), and wherein the electric field in the vertical direction is configured to control the ink particles to move in the vertical direction in the ink accommodating cavity (see first left cavity, fig.5), and the electric field in the horizontal direction is configured to control the ink particles to move in the horizontal direction in the ink accommodating cavity (see middle cavity, see fig.5). Therefore, the requirement is still deemed proper and is therefore made FINAL. Claims 6-12 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected Species, there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on 02/06/2026. Drawings Figure 1 should be designated by a legend such as --Prior Art-- because only that which is old is illustrated. See MPEP § 608.02(g). Corrected drawings in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. The replacement sheet(s) should be labeled “Replacement Sheet” in the page header (as per 37 CFR 1.84(c)) so as not to obstruct any portion of the drawing figures. If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. 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.
