Office Action

§102 §103
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 Objections Claims 3 and 4 are objected to because of the following informalities: Regarding claim 3, the claim is identified as (original) but should be identified as (cancelled) because the limitations of claim 3 are now recited in independent claim 1. For examination purposes, claim 3 is identified as (cancelled). Regarding claim 4, the claim is dependent on cancelled claim 3 but should be dependent on independent claim 1. For examination purposes, claim 4 depends from claim 1. Appropriate correction is required. 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. Claim(s) 13-20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Zhang (US 2021/0356110 A1). Regarding claim 13, Zhang teaches a light modification apparatus comprising: a base area (4) as part of a body defining an opening having a interior surface area (see at least figure 1), the body having a distal end opposite a proximal end and at least one exterior surface (see figure 1), wherein the exterior surface of the body includes at least one attachment element (34; see at least figures 7 and 19) proximate to the proximal end capable of removably coupling to a lighting element (see at least figure 19); and a light modification area (see at least figure 19 where lens 14 is positioned in the attachment element 34) proximate to the distal end. Regarding claim 14, Zhang teaches the light modification apparatus of claim 13, wherein the at least one attachment element (34; see at least figure 7 and 19) is one or more protrusions extending radially extending from the exterior surface (see at least figure 19), and further wherein the at least one attachment element is operatively configured to couple with a lighting element (see paragraph [0078] and at least figures 7 and 19). Regarding claim 15, Zhang teaches the light modification apparatus of claim 14, wherein the interior surface is reflective (reflecting cup 13; see at least figure 1, 7 and 19 and paragraph [0100]) or semi reflective. Regarding claim 16, Zhang et al. teaches the light modification apparatus of claim 13, wherein the light modifier (34) is collapsible along one or more creases or channels (see at least figure 7 where 34 is collapsible via 37 and figure 24B were 34 is foldable/collapsible via 2437). Regarding claim 17, Zhang teaches the light modification apparatus of claim 13, further comprising a gel (see paragraph [0104] where first sealing layer 11 is disclosed) having a body and a lip disposed on an outside rim of the base of the gel (see at least figures 1, 7 and 19), the lip removably coupled to a channel disposed circumferentially about the interior surface (see first housing 4 in at least figure 1). Regarding claim 18, Zhang teaches the light modification apparatus of claim 17, wherein the gel further comprises: a bump circumferentially disposed about an outside surface of the gel (sealing layer 11; see paragraph [0104] where sealing layer 11 comprises a gel). Regarding claim 19, Zhang teaches the light modification apparatus of claim 18, further comprising a second gel (second sealing layer; see paragraph [0022]) having an inside surface with a channel circumferentially disposed along an interior surface of the second gel (see at least figure 1), the channel removably coupled to the bump of the gel.) Regarding claim 20, Zhang teaches the light modification apparatus of claim 13, wherein the light modification area (see at least figure 19) comprises a face proximate to the distal end (4; see at least figure 19), wherein the face includes one or more elements adapted to receive an additional light modification device (12, 1716; see at least figure 19). Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, 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 person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 1, 2, and 4-12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Zhang (US 2021/0356110 A1) in view of Wainright (US 2009/0065715 A1). Regarding claim 1, Zhang teaches a light modification assembly comprising: a base (4; see at least figure 7 and 19) having a base body defining a base opening having a base interior surface (see at least figures 1, 7 and 19), the base body having a base distal end opposite a base proximal end and at least one base exterior surface (see 4 in at least figure 7 and 19), wherein the base exterior surface of the base body includes at least one attachment element (34; see at least figure 19) capable of removably coupling to a lighting element (see at least figure 19); a light modifier (lens 14) having a modifier body defining a modifier opening (see figure 19), the modifier body having a modifier distal end opposite a modifier proximal end and at least one modifier exterior surface (see at least figure 19), the at least one modifier exterior surface having a modifier coupler proximate to the modifier proximal end removably coupled to at least a portion of the base interior surface (see figures 19 and 20). Zhang et al. does not explicitly teach wherein the modifier coupler comprises a bottom surface comprising one or more ferromagnetic materials. Wainright teaches wherein the modifier coupler (base unit 12) comprises a bottom surface (base plate 20) comprising one or more ferromagnetic materials (see paragraph [0030] where ferromagnetic material is disclosed). It would have been obvious to one having ordinary skill in the art before the time of the effective filing date to modify the coupler of Zhang et al. to comprise one or more ferromagnetic materials as taught by Wainright to removably magnetically secure the base unit (see paragraph [0030] of Wainright). Regarding claim 2, Zhang et al. modified by Wainwright teaches the light modification assembly of claim 1, but Zhang et al. is silent about wherein the at least one attachment element is one or more protrusions extending radially from an outside surface of a proximal end of the base, wherein the at least one attachment element is operatively configured to couple with a lighting element. Wainright teaches wherein the at least one attachment element is one or more protrusions (see walls extending from 74 in figure 6) extending radially from an outside surface of a proximal end of the base (74), wherein the at least one attachment element (74) is operatively configured to couple with a lighting element (UV LEDs 78; figure 6). It would have been obvious to one having ordinary skill in the art before the time of the effective filing date to modify the coupler of Zhang et al. to comprise at least one attachment element that is one or mor protrusions as taught by Wainright as an alternative way to secure attach the base to the lighting element. Regarding claim 4, Zhang et al. teaches the light modification assembly of claim 1, wherein removably coupling to the light modifier occurs through a friction fit (see paragraph [0173], 34 can frictionally engage O-rings), press fit, a belt and clasp, a hook and loop fastener, or snap fit. Regarding claim 5, Zhang et al. teaches the light modification assembly of claim 1 wherein the light modifier (34) further comprises an interior surface disposed within the modifier opening, wherein the interior surface is reflective (see paragraph [0116] where reflecting cup 13 is disclosed) or semi reflective. Regarding claim 6, Zhang et al. teaches the light modification assembly of claim 1, wherein the light modifier (34) is collapsible along one or more creases or channels (see at least figure 7 where 34 is collapsible via 37 and figure 24B were 34 is foldable/collapsible via 2437). Regarding claim 7, Zhang et al. teaches the light modification assembly of claim 1, further comprising a gel insert (see paragraph [0104] where first sealing layer 11 is disclosed) having a body and a lip disposed on an outside rim of the base of the gel (see at least figure 1), the lip removably coupled to one of: a channel disposed about an interior surface of the light modifier or a channel disposed about a base interior surface of the base (see first housing 4 in at least figure 1). Regarding claim 8, Zhang teaches the light modification assembly of claim 7, wherein the gel further comprises: a bump circumferentially (see at least figure 1) disposed about an outside surface of the gel (sealing layer 11; see paragraph [0104] where sealing layer 11 comprises a gel). Regarding claim 9, Zhang teaches the light modification assembly of claim 1, further comprising a gel (see paragraph [0104]) having a body and a lip disposed on an outside rim of the base of the gel (see at least figure 1), the lip removably and magnetically coupled to an interior surface of the light modifier or the base interior surface of the base (first housing 4; see at least figure 1). Regarding claim 10, Zhang teaches the light modification assembly of claim 1, further wherein the light modifier (34; see at least figure 7 and 19) further comprises a face proximate to the modifier distal end, wherein the face includes one or more elements (see at least 14,1716 in at least figure 19) adapted to receive an additional light modification device (see at least figure 19). Regarding claim 11, Zhang teaches the light modification assembly of claim 10, wherein the additional light modification device is a grid or a diffuser (1716; see paragraph [0144] where 1716 is a diffuser) that is capable of coupling to the face via a ferromagnetic attachment (1410; see paragraph [0129]). Regarding claim 12, Zhang teaches the light modification assembly of claim 8, further comprising a second gel (second sealing layer; see paragraph [0022]) having an inside surface with a channel circumferentially disposed along an interior surface of the second gel (see at least figure 1), the channel removably coupled to the bump of the gel. Response to Arguments Applicant’s arguments with respect to claim(s) 1, 2, and 4-12 have been considered but are moot because the new ground of rejection necessitated by applicant’s amendment of independent claim 1 and further consideration of applicant’s arguments. Applicant amended claim 1 to include the limitations from dependent claim 3. After consideration of applicant’s arguments, a new reference, Wainright, teaches the limitation, ” wherein the modifier coupler comprises a bottom surface comprising one or more ferromagnetic materials.” added to independent claim 1. After further consideration of applicant’s argument of claim 2, Wainright has been found to teach the limitation. Claim 1, 2 and 4-12 are now rejected as being unpatentable over Zhang (US 2021/0356110 A1) in view of Wainright (US 2009/0065715 A1). See rejection above. Claims 13-20 remain rejected as being anticipated by Zhang (US 2021/0356110 A1). Claim 13 is an independent claim and applicant does not explicitly argue that Zhang does not anticipate claim 13. Therefore claim 13 remains rejected as anticipated by Zhang. Claims 14-20 are remain rejected based on dependency on a rejected base claim.
