Office Action

§102 §103
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 . DETAILED ACTION Acknowledgement of Applicant’s Response The merits of this case have been carefully examined again in light of Applicant’s response filed 06/10/2026. Applicant’s response to the rejections under 35 USC § 112 (a) and (b) and 35 USC § 102 have been fully considered. The 112 (a) and (b) rejection has been withdrawn. However, arguments includes information that forms the basis for new rejections to the claim, as set forth below. This action is made FINAL. THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). Examiner’s Response to Applicant’s Remarks With respect to the 35 USC § 102 rejection, Applicant asserts the following: Stepped tiered profile with concave curved transitions of the front lateral frames Different spatial proportions and block divisions Cap-Like integrated top and bottom end caps These arguments are not persuasive. Regarding the first argument, the change or omission or addition of a few minor details would not justify the multiplication of design patents even though the designs may readily be distinguished from each other by one or more features. Substantial differences are required to render one device patentable over another as a design. The novelty of a design must be judged by the test of ornament, and while the final merit of ornamentation may depend upon the harmonious blending of small details mechanical differences which may make a vast difference in the operativeness of the devices may make no appreciable difference between the devices as designs. Regarding the second argument, the difference between spatial proportions and block divisions is not considered by the examiner to be a patentable distinction, as it is directed only to proportion. Regarding the third argument, again, the caps are directed to proportions. There is no other distinct feature that would differentiate between the top and bottom ends of the claimed design and the Clearhalo reference. They both appear visually flat. Additionally the “installation structure” spears flat with no distinct characteristics form the Cearhalo reference. Claim Refusal – 35 U.S.C. § 102 The rejection of the claim under 35 U.S.C 102, for the reasons set forth in the previous office action has NOT been overcome. Therefore, the claim is again and FINALLY REJECTED under 35 U.S.C. 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. The claim is rejected under 35 U.S.C. 102(a)(1) as being anticipated by NPL “Clearhalo, Half Cylinder Wall Sconce Lamp”, here after Clearhalo, because 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. The appearance and configuration of the Clearhalo reference is substantially the same as that of the claimed design. For anticipation to be found, the two designs must be substantially the same. Gorham Co. v. White, 81 U.S. 511, 528 (1871). The ordinary test is the sole test for anticipation. Int’l Seaway Trading Corp. V. Walgreen Corp., 589 F.3d 1233, 1237 – 38, 1240 (Fed. Cir. 2009). There are not significant differences between the claimed design and the reference that would create patentably distinct designs. PNG media_image1.png 717 414 media_image1.png Greyscale PNG media_image2.png 952 511 media_image2.png Greyscale Prior Art Claimed Design “Two designs are substantially the same if their resemblance is deceptive to the extent it would induce an ordinary observer, giving such attention as a purchaser usually gives, to purchase as article having one design supposing it to be the other.” Door-Master Corp. v. Yorktowne Inc., 256 F.3d 1308, 1313 (Fed. Cir. 2001) (citing Gorham Co. V. White, 81 U.S. 511, 528 (1871)). “The mandated overall comparison is a comparison taking into account significant differences between the two designs, not minor or trivial differences that necessarily exist between any two design that are not exact copies of one another. Just as ‘minor difference between a patented design and an accused article’s design cannot, and shall not, prevent a finding of infringement,’ so too minor difference cannot prevent a finding of anticipation” Int’l Seaway, 589 F. 3d at 1243 (citing Litton Sys., Inc. V. Whirlpool Corp., 728 F.2d 1423, 144 (Fed. Cir. 1984)). Under this standard, the appearance of the Clearhalo, reference is substantially the same as that of the claimed design. Furthermore, the effective filing date of the claimed invention is December 19, 2025; the public availability of the Clearhalo reference is March 22, 2021. Accordingly, the rejection under this statute is proper. Applicants may overcome this rejection by providing convincing evidence that the disclosure was made one year or less before the effective filing date of the claimed invention, and 1) the disclosure was made by the inventor, a joint inventor, or by another who obtained the subject matter directly or indirectly from the inventor or joint inventor; or 2) before such disclosure, the subject matter disclosed had been publicly disclosed by the inventor or a joint inventor or another who obtained the subject matter disclosed directly or indirectly from the inventor or joint inventor. Claim Refusal: 35 U.S.C. § 103 The claim is rejected under 35 U.S.C. 103 as being unpatentable over NPL “Clearhalo, Half Cylinder Wall Sconce Lamp”, here after Clearhalo, dated March 22, 2021. If the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a designer having ordinary skill in the art to which the claimed invention pertains, the invention is not patentable. It is well settled that it is unobviousness is the overall appearance of the claimed design, when compared with the prior art, rather than minute details or small variations in design as appears to be the case here, that constitutes the test of the design patentability. See In re Frick, 275 F2d 741, 125 USPQ 191 (CCPA 1960) and In re Lamb, 286 F2d 610, 128 USPQ 539 (CCPA 1961). The Clearhalo reference has an overall appearance with design characteristics that are basically the same as those of the claimed design, in that both designs: Wall Sconce Lamps Half-cylinder in shape Lamps embedded in a frame and surrounded by the frame PNG media_image1.png 717 414 media_image1.png Greyscale PNG media_image2.png 952 511 media_image2.png Greyscale Clearhalo Claimed Design The claim differs from the design of Clearhalo in the following ways: The frame around the claimed design has smoother angles The appearance of the clamed design would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention in the view of Clearhalo. It would have been obvious to a designer of ordinary skill in the art before the effective filing date of the claimed invention to modify the frame of the Clearhalo design because such modification is no more than simple substitution of a known design element. Moreover, such substitution of one known design element from another known design element in the same field would have been within the skill of an ordinary designer. Additionally, where the only substantial difference between a design and the prior art is one of obvious changes in arrangement and proportioning, the design is not patentable. See In re Stevens, 81 USPQ 362 (CCPA 1949). Accordingly, this results in an appearance over which the claimed design has no patentable distinction. Conclusion The claim is finally rejected as set forth above. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set in 37 CFR 1.136(a). The references cited but not applied are considered cumulative art related to the claimed design. A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any extension fee pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action. Applicant is reminded that any reply to this Refusal must be signed either by a patent practitioner (i.e., a patent attorney or agent registered to practice before the United States Patent and Trademark Office) or by the applicant. If the applicant is a juristic entity, the reply must be signed by a patent practitioner. See 37 CFR 1.33(b).
