Office Action

§102
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 . Note Applicant’s response to the Notice of Non-Compliant filed on 02/08/2026 has been fully considered. Claims 1-5 are canceled, claims 6-9 are added and claims 6-9 are pending. 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. Claims 6-9 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Hyman (US 2003/0035917 A1) as evidenced by Lastusaari et al. (US 2020/0386899 A1). Claim 6: Hyman teaches an image formed of a composition comprising a polymer [1050] and hackmanite as a fluorescent material [1070], wherein the hackmanite fluoresces bright orange with long wave UV light [1070]. The hackmanite meets the claimed visible indicator. Claim 7: Hyman teaches the hackmanite fluoresces bright orange with long wave UV light [1070]. Claim 8: Hyman teaches the hackmanite fluoresces bright orange with long wave UV light [1070]. The long wave UV light meets the claimed UVA LED because evidence shows that the wavelength of UVA is generally considered to be 315-400 nm, the wavelength of UVB is generally considered to be 280-320 and the wavelength of UVC is generally considered to be 100-290 nm (see [0048] of Lastusaari). Lastusaari shows UVA has longer wave than UVB and UVC. Claim 9: Hyman teaches the hackmanite fluoresces bright orange with long wave UV light [1070].
