`Patent 9,537,071
`
`
`
`Petitioner’s opposition fails to provide any basis that would warrant denial
`
`of Patent Owner’s contingent motion to amend.
`
`I.
`
`The Proposed Claims Have § 112 Written Description Support
`
`Claims 27, 28: Petitioner’s argument is that the patent’s fifth embodiment
`
`requires devices having two leads and an additional, non-lead third metal structure.
`
`Op. at 2. That is wrong. Ex. 2030, §VI(A), (B).
`
`To support its argument, Petitioner has to rely on extrinsic evidence (lab
`
`notebooks and draft patent drawings) not part of the specification and thus not part
`
`of the § 112 analysis. Op. at 3-4. It is black letter law that the § 112 inquiry is an
`
`“objective inquiry into the four corners of the specification from the perspective of
`
`a person of ordinary skill in the art.” Streck, Inc. v. Research & Diagnostic Sys.,
`
`665 F.3d 1269, 1285 (Fed. Cir. 2012); Trading Techs. Int'l, Inc. v. Open E Cry,
`
`LLC, 728 F.3d 1309, 1319 (Fed. Cir. 2013) (contrasting the use of extrinsic
`
`evidence in claim construction versus § 112 which looks at the “specification
`
`itself”). Using extrinsic evidence to argue the existence of a third non-lead metal
`
`structure not shown or described is therefore improper. Id.
`
`Looking at Fig. 12 of the patent, even as the Petitioner has annotated it, it is
`
`clear that the shape and configuration of the leads at the interior of the resin
`
`package is not expressly illustrated. Even so, Petitioner asserts that Fig. 12 “shows
`
`the metal of the resin package is divided into three separate structures.” Op. at 2. It
`
`
`
`1
`
`
`
`Case IPR2018-00437
`Patent 9,537,071
`
`
`doesn’t. Rather, Fig. 12 illustrates the division of the metal leads on the outer side
`
`surface (each of the positive and negative leads is divided into three portions), but
`
`the figure does not show any (internal) division of the metal into three separate
`
`structures. Ex. 2030, ¶¶11-12. This is because the underlying arrangement of the
`
`leads is obscured by the resin. Id.
`
`It was therefore unsurprising that, when pressed on cross examination, Dr.
`
`Shanfield admitted he had not opined on the shape of the electrode structure under
`
`the resin in Fig. 12, and that he was not comfortable doing so during his
`
`deposition. Ex. 2033 at 46:21-49:7. Rather than consider the specification to figure
`
`this out, Dr. Shanfield looked to an inventor’s notebook and drafts of figures made
`
`more than five months before the priority application was filed and not included in
`
`the patent. This is improper.
`
`Instead, Petitioner should have looked (as a POSA would have) to the
`
`description of the fifth embodiment found in the specification. Ex. 2030, ¶13. In
`
`introducing the fifth embodiment, the patent states that a “[d]escription of some
`
`configurations employing the substantially same configuration as the light emitting
`
`device according to the first embodiment will be omitted where necessary.” Ex.
`
`2023, ¶98; Ex. 2022, ¶98. In the fifth embodiment, and unlike the first through
`
`third embodiments, the ʼ071 patent omits a lead frame illustration that would
`
`illustrate the specific shape of the leads in the interior of the resin package. Cf.
`
`
`
`2
`
`
`
`Case IPR2018-00437
`Patent 9,537,071
`
`
`Figs. 3, 7, and 10 (embodiments 1-3); see also Ex. 2033, 25:16-26:18, 28:4-6.
`
`Thus, a POSA would consider the description of the first embodiment when
`
`understanding the scope of the fifth embodiment, as instructed in the patent. Ex.
`
`2030, ¶14. The first embodiment, as all agree, shows a resin package consisting of
`
`a resin part and two metal leads. Op. at 6; Ex. 2030, ¶15; Ex. 2033, 49:11-16.
`
`Petitioner’s own arguments further show the deficiencies of its § 112
`
`challenge. For instance, Petitioner acknowledges that the fifth embodiment
`
`describes at least two alternative designs – the leads being “separated respectively,
`
`or jointed.” Op. at 4-5. But Petitioner appears to misunderstand what the patent
`
`teaches, deriding this support for claims 27 and 28 as “ambiguous.” Op. at 4; Ex.
`
`2030, ¶16. There is no ambiguity, and this disclosure identified by Petitioner
`
`supports Nichia. For instance, the disclosure emphasizes that it is the leads that are
`
`separated into six portions at the outer side surface. It does not state that two leads
`
`and a third non-lead metal structure (e.g. a die-bonding pad, or heat sink) are
`
`separated at the outer side surface (as Petitioner contends), and a POSA would not
`
`have construed the specification in that way. Id. ¶17.
`
`Moreover, the disclosure describes a version of the fifth embodiment where
`
`the leads are separated at the “outer side surface 420b,” but also “jointed” at the
`
`package interior, as explained by Dr. Schubert:
`
`
`
`3
`
`
`
`Case IPR2018-00437
`Patent 9,537,071
`
`
`
`In other words, the patent says that the leads are “separated into
`
`six” at the outer side surface. Additionally, in the next sentence,
`
`the patent explains that the leads 422 (i.e. the “pair of positive and
`
`negative leads,” …) may be respectively separated or jointed; that
`
`is, although they are separated into six (as shown in FIG. 12) at the
`
`outer surface, their internal configuration can be that of separate or
`
`jointed anodes and cathodes.
`
`Ex. 2030, ¶16. A POSA would have appreciated the patent as describing a two-
`
`lead device, where each of the two leads separates into three parts at the outer
`
`surface, as set forth in the claims. Id. ¶¶16-18. Contrary to Petitioner, that
`
`arrangement would be operable (having two leads poses no danger of short
`
`circuiting), and moreover, could improve adhesion and manufacturability. Id. ¶¶18-
`
`20. The patent includes other, operable embodiments in which two leads are
`
`separated into more than two at the outer surfaces. See, e.g., FIG. 1 (two leads,
`
`separated into four at the outer surface 20b); 2030, ¶ 19 (“The ’071 patent makes
`
`clear that the number of places that the leads are exposed from the package does
`
`not dictate the number of leads within the package.”). Dr. Schubert has explained
`
`that this position does not change even if Petitioner’s understanding of Fig. 12 is
`
`correct that it depicts an “X” shape as shown in external drawings. Id. ¶20. That is
`
`because the patent’s specification still describes configurations of the fifth
`
`embodiment where the leads are internally jointed.
`
`Petitioner’s arguments regarding elements [27.D]-[27.H] are based on its
`
`
`
`4
`
`
`
`Case IPR2018-00437
`Patent 9,537,071
`
`
`flawed interpretation of Fig. 12 and likewise fail. Ex. 2030, ¶21. For the same
`
`reasons as above, Petitioner’s arguments concerning claim 28 are wrong. Id. ¶22.
`
`Claim 31: Petitioner’s argument improperly incorporates arguments by
`
`reference and should be given no weight. Op. at 8; see n.1 below. Setting this
`
`aside, its challenge fails on the merits. Fig. 11 clearly shows an upper surface and
`
`bottom surface having an etched concave portion. Ex. 2030, §VI(C).
`
`Etched concave portions identified in
`
`yellow (upper surface) and red
`
`(bottom surface). See Ex. 2030, ¶28.
`
`
`
`Because the patent does not redefine these terms, and as Petitioner has not
`
`advanced its own construction, the plain and ordinary meaning of the claim
`
`language should control. Petitioner’s incorporated argument rests on a strained
`
`interpretation of what constitutes the upper and bottom surfaces of the leads.
`
`Specifically, Petitioner’s argument is that Nichia has re-defined the plain and
`
`ordinary meaning of these terms based on its argument that a different prior art
`
`reference did not teach a different claim element for a different, though related
`
`patent. IPR2018-00386, Reply to Patent Owner’s Response at 10-11 (citing Ex.
`
`1025, IPR2017-02011, Pap. 12 at 7, 46-47); Ex. 2030, ¶24. That goes too far. The
`
`claim at issue referred to a concave portion of an inner side wall surface of a pre-
`
`
`
`5
`
`
`
`Case IPR2018-00437
`Patent 9,537,071
`
`
`singulated lead frame, and Nichia pointed out that the prior art reference relied on
`
`did not have this feature. There was no re-definition of terms. Moreover, even
`
`crediting Petitioner’s flawed argument, Petitioner does not explain why a concave
`
`portion of an inner side wall surface of a lead frame (pre-singulation) cannot result
`
`in a device (post-singulation) with a lead having an upper surface with a concave
`
`portion. FIG. 11 shows just that. Ex. 2030, ¶¶23-26.
`
`Petitioner has also improperly incorporated the argument that creating a
`
`concavity by etching must necessarily create a new surface. Nothing in the ʼ071
`
`patent supports Petitioner’s argument that because a surface was formed by
`
`etching, it cannot be considered an upper surface as claimed, especially where that
`
`surface is the top of the lead. Ex. 2030, ¶¶27-29.
`
`II.
`
`The Amendments Do Not Broaden the Claims
`
`Claim 27: Petitioner argues that the change from metal plate to metal lead
`
`broadens the claim. Not so. Ex. 2030, §VII(A). Petitioner appears to assert that the
`
`term lead is broader than plate because a lead does not have to be flat. Op.at 9.
`
`Petitioner’s position is inconsistent with the patent’s disclosures in at least two
`
`ways. First, Petitioner’s argument rests on a highly elided quote, arguing that “‘a
`
`metal plate’ is a ‘flat plate shape . . . which [may have] differences in level or
`
`concavity and convexity” and that metal lead is not so limited. Op. at 9. But the
`
`full sentence from the specification makes clear that metal plates in the ʼ071 patent
`
`
`
`6
`
`
`
`Case IPR2018-00437
`Patent 9,537,071
`
`
`are not limited to flat metal plates: “[a]lthough a metal plate of a flat plate shape
`
`can be used for a lead frame, a metal plate in which differences in level or
`
`concavity and convexity are provided can be used.” Ex. 2030, ¶¶31-32. Tellingly,
`
`Petitioner has identified no lead in the ʼ071 patent that would be broader than the
`
`metal plates described at 9:21-24. Second, Petitioner ignores that the claim has
`
`been narrowed to “leads,” thus excluding plates used for purposes other than
`
`conducting electricity to the LED chip, e.g. heat sinks or mounting plates. Ex.
`
`2030, ¶¶33-34.
`
`Additionally, even if “metal leads” is somehow interpreted to be broader
`
`than “metal plates” (it should not be), Petitioner has not argued that “metal leads”
`
`is also broader than the original language “a metal part”. Ex. 2030, ¶35.
`
`Claim 28: Petitioner argues that the use of “portions of an outer lateral
`
`surface of the resin part” in element [28.F] broadens the original use of “the resin
`
`part.” This is wrong. Ex. 2030, §VII(B). The original claim recited “wherein the
`
`resin part is located at left and right sides of a portion of the metal part.” It was
`
`amended to recite “portions of an outer lateral surface of the resin part” are located
`
`at left and right sides. This is not broader. Ex. 2030, ¶¶37-39. Under any logical
`
`reading, the resin part being located at both the left and right sides of a portion of
`
`the metal part, as originally required, must necessarily refer to portions of the resin
`
`part. Ex. 2030, ¶38. It would be impossible for the entire resin part to be located at
`
`
`
`7
`
`
`
`Case IPR2018-00437
`Patent 9,537,071
`
`
`both a left side and a right side of a metal part. Id.; Ex. 2033, 60:11-14. That
`
`appears to be Petitioner’s implicit interpretation. Additionally, the claim has been
`
`expressly narrowed – not only does the resin part now need to have portions to the
`
`left and right of an exposed surface of the first metal plate (as before), it now needs
`
`to have portions above the plate as well. Ex. 2030, ¶39.
`
`III.
`
`The Proposed Claims Satisfy § 103
`
`Petitioner requested additional pages from the Board. The request was
`
`denied. Paper 29. But rather than accept the Board’s ruling and focus its
`
`challenges, Petitioner placed its voluminous arguments in an expert declaration
`
`instead of the Opposition. Petitioner’s 14 new grounds of obviousness, including a
`
`5-way obviousness combination, are not adequately explained in the Opposition.1
`
`Petitioner here cannot reasonably be said to have met its burden. See Aqua Prods.,
`
`Inc. v. Matal, 872 F.3d 1290, 1324-25 (Fed. Cir. 2017) (en banc); Sirona Dental
`
`Sys. GMBH v. Institut Straumann AG, 892 F.3d 1349, 1357 (Fed. Cir. 2018).
`
`At a minimum, Petitioner needed to identify the Graham factors and
`
`articulate a motivation to combine the numerous references and why a POSA
`
`would have had a reasonable expectation of success in doing so. In re Magnum Oil
`
`
`
`1 This violates the prohibition against incorporation by reference and page limit
`
`rules. See 37 C.F.R. § 42.6(a)(3), 42.24(b)(3), Pap. 29 (denying additional pages).
`
`No weight should be given to the incorporated arguments.
`
`
`
`8
`
`
`
`Case IPR2018-00437
`Patent 9,537,071
`
`
`Tools Int’l, Ltd., 829 F.3d 1364, 1381 (Fed. Cir. 2016). It did not. The opposition is
`
`silent regarding any reasonable expectation of success for the various proposed
`
`combinations aside from conclusorily noting some combinations would be
`
`“straightforward.” E.g., Op. at 10-12, 23-24. It has a threadbare discussion of an
`
`alleged motivation to combine the numerous references that boils down to a few
`
`conclusory statements. E.g., Op. at 12 (“A POSA would have been motivated . . .
`
`to use a thermosetting resin . . . to provide better heat resistance, light resistance
`
`and adhesion . . . .”), 16 (“[I]t would have been obvious to combine Lin’s similar
`
`disclosures.”). Further, it is difficult to decipher from the opposition the precise
`
`nature of the grounds being asserted, which appear to be introduced implicitly in
`
`section headings and described together without detailed explanation. E.g., Op. at
`
`21. These exemplary deficiencies show why Petitioner failed to meet its burden.
`
`A. Hsu lacks the claimed resin part and grounds based on Hsu are
`therefore deficient.
`
`Petitioner’s § 103 challenges also fail on the merits. Each ground is based on
`
`the incorrect position that both the reflecting ring 30 and the encapsulant 50 in Hsu
`
`correspond to the claimed “resin part.” E.g., Op. at 10. This is wrong, and
`
`inconsistent with the ʼ071 patent, in which a “sealing member” (such as Hsu’s
`
`encapsulant 50) is disclosed and claimed as being distinct from the “resin part.”
`
`Ex. 2030, ¶¶44-47. That is, because the encapsulant 50 is not part of the claimed
`
`resin part, Hsu does not meet the requirements for the claimed resin part. Id.
`
`
`
`9
`
`
`
`Case IPR2018-00437
`Patent 9,537,071
`
`
`
`First, the claims differentiate between a resin part of the resin package and a
`
`sealing member (or encapsulant). The independent claims require a resin package
`
`having a resin part and two metal leads or plates. Dependent claims further limit
`
`the device to include a sealing member that contains two or more kinds of
`
`phosphors (e.g. original claims 2 and 19, substitute claim 31). Thus, under the
`
`doctrine of claim differentiation, the sealing member is something different than
`
`the claimed resin part. Chicago Bd. Options Exch., Inc. v. Int’l Sec. Exch., LLC,
`
`677 F.3d 1361, 1369 (Fed. Cir. 2012) (referring to the “general presumption that
`
`different [claim] terms have different meanings”).
`
`Second, the patent describes the resin part and the sealing member 30 (or
`
`encapsulant) as being different, and as having competing purposes. Ex. 1001, 6:49-
`
`65, 10:9-33, 18:3-33, FIG. 2. The patent consistently groups leads 22 and resin
`
`part 25 under the designation resin package 20, and separately depicts the sealing
`
`member 30 (or encapsulant) as not being part of the resin package 20. Ex. 2030,
`
`¶46. This distinction between the resin part of the resin package and the sealing
`
`member of the device also serves a practical purpose. The resin part is reflective,
`
`while the sealing member 30 (and Hsu’s encapsulant 50) allows light to escape.
`
`Ex. 2030, ¶¶46-47; ʼ071 Patent, 8:59-9:20, 10:9-32. Hsu itself has the same
`
`distinction. Ring 30 is “an opaque white plastic material,” while encapsulant 50 is
`
`a clear epoxy that allows light to escape (otherwise the device would be
`
`
`
`10
`
`
`
`Case IPR2018-00437
`Patent 9,537,071
`
`
`inoperable). Ex. 1030, 4:16-27, FIG. 10; Ex. 2033, 68:16-70:16.
`
`Because the encapsulant 50 of Hsu is not a component of the resin part, Hsu
`
`fails to disclose or suggest a portion of the resin part being coplanar with a portion
`
`of the metal leads at four outer lateral surfaces as required by claims 27 (element
`
`[27.E]) and 28 (elements [28.D] and [28.H]). See Ex. 1030, FIG. 12.
`
`Further, claim 27 requires that the resin package consist of the resin part and
`
`two metal leads. In Hsu, the identified resin part of the resin package includes
`
`reflecting ring 30 (molded in a first molding step) and encapsulant 50 (molded in a
`
`second molding step to produce base 51 and dome-like protrusion 52). The resin
`
`package therefore includes multiple, separately molded resins and does not consist
`
`of a (single) resin part as claimed. Ex. 2030, ¶48; Ex. 1030, FIG. 12. See Digene
`
`Corp. v. Third Wave Techs., Inc., 323 F. App’x 902, 909 (Fed. Cir. 2009) (holding
`
`that “the clause ‘consists of’ generally requires that the word ‘an’ following it be
`
`limited to one and only one”). The other references do not cure this deficiency, and
`
`thus Petitioner’s challenge to claim 27 also fails for this additional reason. Id.; see
`
`also Ex. 2030, ¶¶49-53 (grounds with Lin are inappropriate because Lin teaches an
`
`opposing method of creating a resin part that is incompatible with Hsu and/or
`
`Urasaki); Ex. 1010, ¶ [0027], FIG. 4g; Ex. 1031, ¶¶0004-0007, FIGS. 1, 5-6.

`
`
`
`Case IPR2018-00437
`Patent 9,537,071
`
`
`
`B. Glenn is not appropriate art to cite against light emitting devices.
`
`In a district court action with respect to the parent application of the ʼ071
`
`patent, Glenn was rejected as a viable reference for purposes of § 103. Ex. 2024 at
`
`44 (FF157, finding Glenn in combination with LED references would not have
`
`predictably yielded a viable LED device). The district court went so far as to state
`
`that a POSA would have “dismissed” it because it related to integrated circuits
`
`(“IC”) which have fundamentally different purposes. Ex. 2024 at 44-45 (FF158-
`
`FF161). The district court even rejected the premise that Glenn would be combined
`
`with the very same reference – Urasaki (Ex. 1031) – used by Petitioner in each of
`
`the grounds with Glenn. Ex. 2024 at 44-48 (FF171, referring to Urasaki by its
`
`assignee, “Hitachi”). The Federal Circuit affirmed. Ex. 2036 at 12-13. With this
`
`backdrop, Petitioner’s decision to say nothing of these differences, not discuss
`
`expectation of success, or even give a meaningful discussion of motivation is
`
`particularly glaring. There is no summary of Glenn, or acknowledgement that it
`
`has previously been deemed incompatible with Urasaki.
`
`Further, because of the fundamentally different purposes and functions—
`
`LEDs emitting light and ICs being isolated from light—a POSA would not have
`
`relied on Glenn to modify Hsu or any other LED reference. Ex. 2030, ¶¶54-57.
`
`Thus, Petitioner’s challenge to claim 31 fails for this additional reason, particularly
`
`as Glenn is the only reference identified for elements [31.B], [31.C], and [31.D].
