`
`OVERVIEW OF THE ‘518 PATENT
`
`Technology
`
`Lighting fixtures come in a variety of shapes and sizes. One particular shape is a low-
`
`profile fixture such as a low-profile ceiling fixture. Low-profile fixtures generally sit close to the
`
`wall or ceiling and do not protrude substantially into the room. Low-profile fixtures are
`
`commonly constructed of metal, plastic and glass in a wide variety of forms or trims, reflecting a
`
`wide variety of aesthetic choices. Low profile fixtures include fixtures that sit entirely on a
`
`surface, such as a wall or ceiling, and have a lateral extent that is significantly greater than their
`
`“height” as measured from the surface; plus fixtures that have a portion that extends into an
`
`opening in the surface while the exposed portion has a lateral dimension that is significantly
`
`greater than the “height” of the fixture above the surface.
`
`Some lighting fixtures, including low profile lighting fixtures, use light emitting diodes
`
`(“LEDs”) to produce light. LEDs produce heat. That heat must be dissipated. The waste heat
`
`from LEDs that produce light that can illuminate a surface or room, as opposed to low power
`
`LEDs used as indicators, is commonly dissipated by means of a heat sink – one or more pieces
`
`5 37 C.F.R. §§ 42.103(a) and 42.15(b).

`U.S. Patent 8,672,518
`Petition for Inter Partes Review
`of thermally conductive material (e.g. metal) that carry the heat away from the LEDs and
`
`dissipate it into the air.
`
`LEDs also require power conditioning. Rather than using residential or commercial line
`
`voltage (e.g. 120 volts AC), LEDs commonly require lower-voltage, current-controlled, DC
`
`power. LED power converters (commonly referred to as “drivers”) come in a wide variety of
`
`sizes, shapes and power levels.
`
`The ‘518 Patent
`
`The ‘518 Patent generally concerns heat dissipation in LED-based lighting fixtures,
`
`including low-profile lighting fixtures; and means to connect said fixtures to the building power
`
`lines. ‘518 Patent at Abstract; 1:15-17, 2:42-58. The luminaire of the ‘518 Patent includes one
`
`or more LEDs, a heat spreader, a heat sink, and an optic for focusing or diffusing light into the
`
`illuminated area. Id. at 1:46-53. The LED generates heat; the heat spreader transfers the heat to
`
`a heat sink; and the heat sink dissipates the heat into the air. Id. 1:47-53, , 2:23-32. The ‘518
`
`Patent defines “low-profile” in terms of the height-to-diameter ratio of the combined heat
`
`spreader, heat sink, and optic. Id. at 1:53-56, 2:16-19, 4:52-56. Essentially, the ‘518 Patent
`
`describes using the fixture’s own trim as the heat sink in order to keep the fixture cool and low-
`
`profile.
`
`Specifically, the ‘518 Patent claims a luminaire comprising a heat spreader, a “ring
`
`shaped” heat sink around its outer periphery, an optic, an LED light source, and a means to
`
`connect the fixture to the building power lines, wherein the heat sink, heat spreader and optic in
`
`combination have a combined height-to-diameter ratio of 0.25 and are sized to cover the opening
`
`of a standard 4-inch light can fixture or junction box.
`
`1. Claim 1 is illustrative:
`
`1. A luminaire and accessory kit in combination, the combination comprising:

`
`a luminaire, comprising:
`
`a heat spreader; a heat sink disposed in thermal communication with the heat spreader;
`
`light source comprising a plurality of light emitting diodes (LEDs) disposed in
`
`thermal communication with the heat spreader; a power supply electrically
`
`connected to the light source; an electrical supply line having a first end
`
`connected to the power supply, and a second end connected to a plug-in
`
`connector; and, an optic disposed in optical communication with the LEDs; and
`
`an accessory kit, comprising:
`
`at least one of: a first pre-wired jumper comprising a pair of insulated electrical wires
`
`having a first plug-in connector electrically connected at one end and an Edison
`
`base electrically connected at the other end; and, a second pre-wired jumper
`
`comprising a pair of insulated electrical wires having a second plug-in connector
`
`electrically connected at one end and cut wire ends at the other end;
`
`wherein the plug-in connector of the first pre-wired jumper and the second pre-wired jumper are
`
`each configured to electrically engage with the plug-in connector of the electrical supply line.
`
`Figure 12 of the ‘518 Patent illustrates an embodiment of Claim 1.

`As shown in Figure 12, the LED light source 120 is mounted on the “heat spreader” 105
`
`which is in thermal communication with heat sink 110. An outer optic 115 spans the heat
`
`spreader 105. A power conditioner 140, 160 mounted on the heat spreader 105 provides DC
`
`power to the LEDs 120. The heat spreader 105, heat sink 110, and outer optic 115 in
`
`combination define an overall outer dimension (i.e. diameter) of the light fixture large enough to
`
`cover the opening of a standard four-inch light can fixture and standard four-inch junction box
`
`(not shown). ‘518 Patent at 6:7-31.
`
`FIG. 31 depicts the claimed accessory kit.
`
`
`
`The accessory kit includes a first pre wired jumper 520 and a second pre wired jumper
`
`525 with each pre wired jumper including a pair of wires 521 and 526 and a plug in male
`
`connector 535. The first pre wired jumper 520 includes a pre wired Edison base 540. The
`
`second pre wired jumper 525 includes open wire ends 527. ’518 Patent at 10:58-11:24.
`
`Prosecution History of the ‘518 Patent and ‘968 Patent
`
`The ‘518 Patent was filed on May 21, 2012 as U.S. Application No. 13/476,388 as a
`
`Continuation in Part Application of Application No. 12/775,310, now Pat. No. 8,201,968
`
`claiming the benefit of priority to U.S. Provisional Application No. 61/248,665 filed October 5,

`
`CHICAGO/#2981596

`
`
`
`

`

`U.S. Patent 8,672,518
`Petition for Inter Partes Review
`2009. The ‘968 Patent issued on June 19, 2012. In allowing the claims, the Examiner stated
`
`“Claim 1 is allowed because the prior art of record failed to teach a kit in combination with the
`
`luminaire which includes a luminaire and accessory kit in combination.”
`
`The prosecution history of the ‘968 Patent is particularly relevant to this Petition as 1) the
`
`‘518 patent is a continuation in part of the ‘968 Patent, and 2) the claims of the ‘968 Patent are
`
`similar to the claims of the ‘518 Patent. U.S. Application No. 12/775,310 originally contained
`
`twenty claims. Ex. 1006 (Original Claims). In the first and only office action, the Examiner
`
`rejected claims 1-8 and 10-16 as anticipated by Roberge et al. (WO 2008/137732)7 (“Roberge”)
`
`and rejected claims 1-3, 7-10, and 17-20 as anticipated by Chou (U.S. Appl. Pub.
`
`No. 2009/0086474)8 (“Chou”). Ex. 1007 (Office Action mailed October 12, 2011). No claims
`
`were allowed. Id. at 1.9
`
`In response, Applicants amended independent claims 1 and 17 to define the shape of the
`
`heat sink as “substantially ring-shaped” and “ring-shaped,” respectively.10 Ex. 1008 (Reply to
`
`Office Action) at 2, 5. Applicants further amended the independent claims to recite that the
`
`LEDs “are disposed on the heat spreader such that the heat spreader dissipates heat from the
`
`LEDs.” Id. at 2, 5. Applicants amended claim 17 to add a 0.25 height/diameter ratio limitation
`
`
`7 The International PCT Publication WO 2008/137732 is equivalent to the disclosure in U.S. Pat.
`No. 7,828,465 to Roberge et al. filed May 2, 2008 and issued Nov. 9, 2010. Ex. 1011.
`8 U.S. Appl. Pub. No. 2009/0086474 is equivalent to the disclosure in U.S. Pat. No. 7,670,021 to
`Chou filed May 20, 2008 and issued March 2, 2010. Ex. 1010.
`9 Claim 17 was renumbered to claim 20 upon issuance of the ‘968 Patent.
`10 Applicants also amended the claims to require that the LEDs be “disposed on” the heat
`spreader, id. at 2, 5 (Amended Claims), and then analogized the Roberge “bezel plate” to a heat
`spreader, and found the Roberge heat sink “not disposed around and coupled to an outer
`periphery of the heat spreader,” id. at 7 (Remarks). Petitioner is unsure what to make of the
`discussion. The bezel of Roberge has little to do with heat management.

`

`

`U.S. Patent 8,672,518
`Petition for Inter Partes Review
`(a limitation previously found anticipated by Roberge and Chou in the Examiner’s rejection of
`
`claim 1). Id. at 5.
`
`As to the Examiner’s rejection of claim 1 over Roberge, Applicants did not contest that
`
`Roberge discloses the claimed height/diameter ratio of 0.25 but pointed instead to Fig. 3B and
`
`argued that the heat sink in Roberge is not “ring-shaped.” Id. at 7 (Remarks). Applicants did not
`
`point to the portion of Roberge disclosing that the heat sink can instead have a “diameter” and
`
`may be “round.” Id. at 7; Roberge at 24:21-24 (“diameter”); Provisional at ¶112 (“round”).11
`
`As to the Examiner’s rejection of Claims 1 and 17 over Chou, Applicants pointed to
`
`“heatsink 14” and argued it (i) is not substantially ring-shaped and (ii) causes Chou to not meet
`
`the 0.25 H/D ratio limitation. Id. at 8. Applicants did not point to the thermally conductive trim
`
`12 of Chou, which is a heat sink of a shape and profile nearly identical to the trim of Fig. 12
`
`(110) of the ‘968 Patent.
`
`Without further comment, the Examiner allowed all claims on the basis of “[a]pplicant’s
`
`amendment and accompanying remarks.” Ex. 1009 (‘968 Notice of Allowance) at 2.
`
`
`
`III. OVERVIEW OF THE PRIOR ART
`
`As set forth below, several prior art references accomplish the same goal in the same
`
`manner as the ‘968 Patent: dissipating heat from a low-profile LED fixture by using the fixture’s
`
`own trim or periphery as a heat sink.
`
`Overview of Chou
`A.
`U.S. Pat. No. 7,670,021 (“Chou”) (Ex. 1010), which issued on March 2, 2010 from an
`
`application filed on May 20, 2008, claiming priority to provisional application 60/975,657 filed
`
`
`11 The Roberge provisional was incorporated by reference in the Roberge ‘465 Patent. Ex. 1011
`at 1:7-15.

`on October 10, 2007, discloses a low-profile ceiling LED luminaire that dissipates heat into the
`
`surrounding air via an exterior trim. Chou at 1. Chou discloses one embodiment as follows:
`
`
`Chou at Fig. 2a, 2b.
`
`
`
`Chou dissipates heat in two ways. The first is through a metal trim 12 on the underside
`
`of the fixture. Id. at 3:44-47, 4:4-16, Fig. 2b at 12. LEDs 15 are mounted on the underside of
`
`the trim 12. An LED driver, circuit board 17, is mounted on the top side. Id. at 4:21-27. The
`
`center portion of the trim transfers heat out to the outer portion of the trim, flange 22. Id. at 5:1-
`
`11. From there it is dissipated into the air. Id. at 5:5-11, 7:44-46. The “trim” in Chou thus has
`
`two portions: (1) a flat interior portion that spreads the heat, and (2) an outer, ring-shaped flange
`
`that dissipates the heat into the air. See also Figs. 4a and 4b (showing flat portion and flange).
`
`The trim’s height (including optic) is 42 mm; its diameter 200 mm; the ratio is 0.21. Id. at 5:24-
`
`28.
`
`The second way in which Chou dissipates heat is through an additional, secondary
`
`heatsink 14, mounted on the top side of the fixture, which extends up into a conventional ceiling
`
`“can.” Id. at Fig. 2b, 3, 8; 4:40-54. Because the upper heat sink is trapped up inside the can, “a

`majority of the heat [is] dissipated [through the] trim 12 outside the housing,” i.e., into the room.
`
`Id. at 5:9-10.
`
`Overview of Zhang
`B.
`U U.S. Pat. No. 7,722,227 (“Zhang”), which issued on May 25, 2010 upon an application
`filed on October 10, 2008 claiming priority to provisional application 60/979068, filed on
`October 10, 2007, likewise discloses a low-profile ceiling fixture that dissipates heat to the
`surrounding air via a ring-shaped trim. Zhang at 1. An illustration of Zhang is as follows:
`
`
`
`
`Zhang at Figs. 5 and 10.
`Zhang dissipates heat as follows: The LEDs and a driver are mounted onto a thermally-
`conductive “trim cup” (112) at the top of the fixture. Id. at 8:10-12, 9:44-48. The trim cup
`spreads the LED-generated heat to a peripherally surrounding baffle/heat sink/trim combination
`(98, 100, 52). Id. 7:63-8:1, 9:37-47, Fig. 5. The baffle/heat sink/trim combination is shaped like
`a top hat. The trim portion of the top hat is ring-shaped. Id. at Fig 5 (item 52). The trim portion
`dissipates the heat into the air. Id. at 7:9-13, 7:31-34.

`IV. CLAIM CONSTRUCTION
`
`A claim in an inter partes review of an unexpired patent is given the “broadest reasonable
`
`construction in light of the specification.” 37 C.F.R. § 42.100(b); Cuozzo Speed Techs., LLC v.
`
`Lee, 136 S. Ct. 2131, 2142, --- U.S. --- (2016). Claim terms are given their ordinary and
`
`customary meaning, as would be understood by one of ordinary skill in the art in the context of
`
`the entire disclosure. In re Translogic Tech., Inc., 504 F.3d 1249, 1257 (Fed. Cir. 2007).
`
`1.
`
`“heat spreader” and “heat sink”
`
`The term, “heat spreader,” ordinarily refers to a device used to move thermal energy from
`
`a (typically concentrated) heat source to another location where the thermal energy can be

`absorbed or dissipated. Roberts Decl, ¶49. The heat spreader can be integrated into the heat
`
`sink, or can be a small thermal gap pad sandwiched between a heat source and a heat sink to
`
`accommodate small geometric discontinuities, or it can be a separate device made from
`
`thermally conducting material. Id. The broadest reasonable interpretation of these terms, in light
`
`of the specification, is that the “heat spreader” is that which moves heat from the heat source to
`
`the heat sink. The “heat sink” is that which dissipates the heat into the air. Id.
`
`2.
`
` “ring-shaped”
`
`The broadest reasonable interpretation of “ring-shaped” is: generally round with a hole or
`
`cavity in the middle. Roberts Decl, ¶50. A “ring-shaped” structure surrounds a space or cavity.
`
`Id. It need not be perfectly circular nor perfectly smooth. Id. Similarly, the interior hole need
`
`not be perfectly round nor perfectly smooth. Id. The specification neither defines, limits, nor
`
`uses the term – further suggesting a broad interpretation.

`
`Claim 1
`
`1.
`
` “a heat spreader; a heat sink disposed in thermal communication with the heat
`spreader”
`
`FIG. 8 of the Tickner shows a heat spreader 310a that forms the bottom surface of heat
`
`sink 310. Id. at para. [0050]. (“As illustrated in FIG. 10, the heat sink 310 is configured to
`
`dissipate heat from the LED package 305 along a heat-transfer path that extends from the LED
`
`package 305, through the bottom surface 310a of the heat sink, and to the fins 311 via the core
`
`905.) Further, the specification of the Ticker states “In certain exemplary embodiments, the
`
`reflector housing is formed integrally with the heat sink” and “the reflector housing 320 is
`
`configured to act as a secondary heat sink for conducting heat away from the LEDs.” Tickner,
`
`¶0052. Therefore, Tickner discloses the claimed heat spreader and heat sink in thermal
`
`communication.
