`
`Petitioner provides this Reply under 37 C.F.R. § 42.23 to Patent Owner’s
`
`Corrected Response dated October 9, 2013 (Paper 16) (“Response”). With this
`
`Reply and its Petition filed on February 15, 2013, Petitioner requests relief through
`
`the cancellation of claims 1-3, 8, 10, 16-19, 21, 25-33, 35 and 36 of the '138 patent
`
`(Ex. 1001).
`
`I.
`
`INTRODUCTION
`
`The Board instituted inter partes review based on the anticipation of claim 1
`
`by Kuwahara (Ex. 1007). (Decision (Paper 8) at 21.) The Board further instituted
`
`review of the remaining claims (which all depend from claim 1) as anticipated by
`
`Kuwahara or obvious in view of Kuwahara and other references under five
`
`grounds. (Id.) Patent Owner initially informed the Board and Petitioner that it did
`
`not intend to file a response to the Decision. Then, five days before the response
`
`deadline, Patent Owner changed its mind.
`
`The filed Response is noteworthy for what it lacks. Patent Owner did not
`
`substantively address each of the five grounds. Patent Owner did not provide
`
`expert testimony to address the content of any of the references as understood by a
`
`one of ordinary skill in the art. Nor did Patent Owner rebut the testimony about
`
`these references by Dr. Iezzi, whose declaration (Ex. 1017) was submitted with the
`
`Petition. Even though the Board repeatedly credited Dr. Iezzi’s testimony (see,
`
`e.g., Decision at 13, 14 and 16), Patent Owner also did not depose him.
`
`la-1231065
`
`1
`
`

`

`IPR2013-00149
`
`Instead, Patent Owner has only focused on a single limitation of claim 1:
`
`“said discontinuous layer including discrete islands of metal in an adhesive.”
`
`Patent Owner does not dispute that Kuwahara discloses a discontinuous layer
`
`including discrete islands of metal or even an adhesive. Rather, Patent Owner has
`
`plucked a single sentence from Dr. Iezzi’s declaration to contend that the evidence
`
`is insufficient to show the discrete islands being in adhesive.
`
`Petitioner disagrees. Kuwahara expressly discloses a number of facts – such
`
`as roll coating adhesive on the discrete islands, a significant distance between
`
`discrete islands and the application of heat and pressure – that as understood by a
`
`skilled artisan clearly substantiates the Board’s finding that the discrete islands are
`
`in adhesive.
`
`II. MATERIAL FACTS
`
`Petitioner disputes facts numbered “2” and “11” in Patent Owner’s
`
`Response. (Response at 2-5.) In addition, Petitioner provides the following
`
`material facts.
`
`12. Kuwahara (Ex. 1007) at 4:6-11 discloses: “The distance between the
`
`islands is set to between 100 and 5000 Å. If the distance between the islands is
`
`smaller than 100 Å, then a tunneling current flows, so that the insulating
`
`characteristic degrades. If the distance between the islands is larger than 5000 Å,
`
`la-1231065
`
`2
`
`

`

`IPR2013-00149
`
`the amount of metal as a whole is insufficient and fine metallic luster cannot be
`
`obtained.”
`
`13. Patent Owner’s Ex. 2002 at page 1 (paragraph 1) provides: “Roll
`
`coating machines are commonly used for the application of a liquid to the surface
`
`of a part. Rollcoaters can be used to apply liquid adhesives, paints, oils, and
`
`coatings such as varnish or clear finish coats.” (Emphasis added.)
`
`14. Ex. 2002 at page 10 (paragraph 2) further provides: “Certain types of
`
`adhesives (such as hotmelts, waxes and certain high viscosity materials) require
`
`that the machine or the rollers be heated to melt the material or lower the viscosity
`
`to a point where it can be applied.” (Emphasis added.)
`
`15. The Adhesives Technology Handbook (Ex. 1018 at ¶ 9 and App. AA)
`
`provides: “PVC and copolymers of both vinyl chloride and vinyl acetate with
`
`other monomers, such as maleic acid esters, alkyl acrylates, maleic anhydride, and
`
`ethylene, are also used to produce solvent-based adhesives.” (Emphasis added.)
`
`16. As stated in Ex.1018 at ¶ 17: In a flowing adhesive, the huge number
`
`of polymer chains would be oriented in every conceivable direction.
`
`17. As shown by Zang, Y.-H and Carreau, P. J., A Correlation Between
`
`Critical End-to-End Distance for Entanglements and Molecular Chain Diameter of
`
`Polymers, J. Appl. Polym. Sci. (1991), 42: 1965–1968 (Ex. 1018 at ¶ 18 and App.
`
`la-1231065
`
`3
`
`

`

`IPR2013-00149
`
`CC), the diameter of a vinyl chloride-vinyl acetate adhesive polymer chain would
`
`be 12.9 Angstroms or less, which is less than a 5000 or 500 Angstrom spacing.
`
`18. As stated in Ex. 1018 at ¶ 20: Adhesives can be applied “upside
`
`down” by roll coating because the driving forces, such as (a) surface tension; (b)
`
`capillary action; (b) the adhesive’s polymer chain small molecular diameter,
`
`mobility, and orientation; and (c) intrinsic molecular inter-diffusion, cause the
`
`adhesive to spread into the crevices of a surface and obtain intimate contact with
`
`the surface.
`
`19. As stated in Ex. 1018 at ¶ 28: It is known that most of the solvent in
`
`an adhesive would evaporate during a lamination process.
`
`III. RESPONSE TO PATENT OWNER’S ARGUMENTS
`
`A. The Proper Legal Analysis
`
`Patent Owner begins with a six page tutorial on anticipation, but at least
`
`misses two key points. (Response at 14-20.) First, a reference anticipates if a
`
`skilled artisan could take the reference’s teachings in combination with his or her
`
`own knowledge of the particular art and be in possession of the claimed invention.
`
`In re Graves, 69 F.3d 1147, 1152 (Fed. Cir. 1997); Helifix Ltd. v. Blok-Lok, Ltd.,
`
`208 F.3d 1339, 1347 (Fed. Cir. 2000) (same and further discussing “evidence on
`
`how a person of ordinary skill in the art would understand” a reference for
`
`anticipation). Second, anticipation is “an issue of fact” and “the question of
`
`la-1231065
`
`4
`
`

`

`IPR2013-00149
`
`whether a claim limitation is inherent in a prior art reference is a factual issue on
`
`which evidence may be introduced.” In re Schreiber, 128 F.3d 1473, 1477 (Fed.
`
`Cir. 1997) (internal citations omitted). In reaching anticipation in its Petition,
`
`Petitioner explained the relevant facts of Kuwahara and how these facts would be
`
`understood by a skilled artisan (who was defined, without objection, as having a
`
`bachelor’s degree in chemical engineering, material science or chemistry and at
`
`least five years of experience working with or researching thermoplastic films and
`
`composites). (Petition (Paper 3) at 7-19; Iezzi First Dec. (Ex. 1017) at ¶¶ 19, 37-39
`
`and 50-97.) In contrast, the rebuttal provided by Patent Owner is mere attorney
`
`argument, which is insufficient to rebut the factual finding of anticipation by a
`
`preponderance of evidence. 35 U.S.C. § 316(e).
`
`B.
`
`The Adhesive Of Kuwahara Is A Liquid
`
`Kuwahara discloses applying its adhesive on the discrete islands by roll
`
`coating. (Ex. 1007 at 5:14-27.) Patent Owner contends that Dr. Iezzi erroneously
`
`understood the adhesive to be a liquid based on this disclosure of roll coating.
`
`(Response at 22-23.) However, Patent Owner’s own Exhibit – Ex. 2002 –
`
`confirms Dr. Iezzi’s understanding of Kuwahara to one of ordinary skill in the art.
`
`(Ex. 1018 at ¶ 8.)
`
`The very first two sentences of Ex. 2002 provide: “Roll coating machines
`
`are commonly used for the application of a liquid to the surface of a part.
`
`la-1231065
`
`5
`
`

`

`IPR2013-00149
`
`Rollcoaters can be used to apply liquid adhesives, paints, oils, and coatings such as
`
`varnish or clear finish coats.” (Emphasis added.) Ex. 2002 further states at 10:
`
`“The type of adhesive or coating will influence the way the liquids are brought to
`
`the metering point.” (Emphasis added.) There is no mention at all in Ex. 2002 of
`
`non-liquids being applied by roll coating. Thus, based on Patent Owner’s own
`
`evidence relating to roll coating, the skilled artisan would have understood
`
`Kuwahara’s roll coating an adhesive necessarily to be roll coating a liquid. Indeed,
`
`the specific type of adhesive disclosed in Kuwahara is applied as a liquid. (Ex.
`
`1018 at ¶ 9.)
`
`Patent Owner tries to undermine this proper understanding of Kuwahara by
`
`pointing to the irrelevant issue of electrostatic printing process of Xerox machines.
`
`(Response at 21.) This argument is, once again, belied by Ex. 2002. It provides at
`
`page 1:
`
`A roll coating machine works by transferring a layer of coating from
`
`the surface of a roller to the surface of a part. When this happens, a
`
`phenomenon know[n] as ‘film splitting’ occurs. The layer of coating
`
`on the surface of the roll splits – part of it stays on the roller, and part
`
`sticks to the surface of the part. The percentage of coating that sticks
`
`to the part (the substrate) depends on the surface characteristics of
`
`both the roller and the substrate.
`
`
`
`la-1231065
`
`6
`
`

`

`IPR2013-00149
`
`That is, roll coating relies on a liquid’s adhesive properties to itself, to the surfaces
`
`of the roller and to the application surface. (Ex. 1018 at ¶ 11.) In comparison,
`
`Xerox machines transfer particles from a charged toner drum to paper using
`
`electrostatic charge—there is no film splitting in a Xerox machine. (Id.)
`
`C. The Liquid Adhesive Would Flow Into The Voids In Kuwahara’s
`Metallized Layer
`
`Having failed to undermine the proper understanding of Kuwahara’s
`
`adhesive as a liquid, Patent Owner next turns to the operation of the liquid
`
`adhesive. Yet again, Patent Owner cannot escape the facts of Kuwahara.
`
`1.
`
`Patent Owner inaccurately characterizes Kuwahara and the
`claims of the '138 patent
`
`Patent Owner states: “Even if the copolymer resin of Kuwahara were roller
`
`coated as a liquid onto the surface of the metallized film, Wavelock presents no
`
`evidence that the liquid would be capable of filling a 500 Angstrom void.”
`
`(Response at 24.)
`
`This statement is factually wrong. Kuwahara explicitly discloses distances
`
`between islands up to 5000 Angstroms – not 500 Angstroms. Specifically,
`
`Kuwahara at 4:6-7 states: “The distance between the islands is set to between 100
`
`and 5000 Å.” Knowing that 5000 Angstroms is large on a molecular scale, Patent
`
`Owner fails to even mention this disclosure in its Response. It is also
`
`la-1231065
`
`7
`
`

`

`IPR2013-00149
`
`conspicuously silent on whether the liquid adhesive would flow around discrete
`
`islands with a spacing of 5000 Angstroms.
`
`Patent Owner also repeatedly mischaracterizes the '138 patent as requiring
`
`the liquid adhesive “fill” the spaces between the discrete islands. (See, e.g.,
`
`Response at 5, 20 and 24.) All that is required by the claims is that the
`
`discontinuous layer includes “discrete islands of metal in an adhesive.” Any
`
`amount of adhesive that flows around the areas between the islands would cause
`
`the discrete islands to be “in an adhesive.” (See, e.g., Ex. 1017 at ¶ 39.)
`
`2.
`
`The viscosity of the adhesive in Kuwahara was low enough
`to flow between the islands
`
`Patent Owner argues that Kuwahara’s adhesive could be so viscous that it
`
`would not flow and “fill” any voids. (See, e.g., Response at 24.) Patent Owner
`
`again fails to take into account how the skilled artisan would understand the facts
`
`of Kuwahara. (Ex. 1018 at ¶ 13.) As explained in Section B, the skilled artisan
`
`would properly understand that Kuwahara’s adhesive was applied as a liquid given
`
`its disclosure of roll coating on the discrete islands. Roll coating, as Patent
`
`Owner’s Ex. 2002 explains, is a method of applying a liquid film layer. Further,
`
`highly viscous liquids cannot be rolled coated as they would form clumps or bind
`
`up the equipment. (Ex. 1018 at ¶ 14.) Once again, Ex. 2002 provides: “Certain
`
`types of adhesives (such as hotmelts, waxes and certain high viscosity materials)
`
`require that the machine or the rollers be heated to melt the material or lower the
`
`la-1231065
`
`8
`
`

`

`IPR2013-00149
`
`viscosity to a point where it can be applied.” (Ex. 2002 at 10 (emphasis added);
`
`see also Ex. 1018 at ¶ 14.)
`
`Further, Kuwahara states that the “vinyl chloride-vinyl acetate copolymer
`
`resin was applied to the deposited Sn layer of the examples to a thickness of 2µm
`
`with a roller coater, then heated with a 2002 µm thick polyvinylchloride film and
`
`laminated under pressure.” (Ex. 1007 at 5:19-22 (emphasis added).) The skilled
`
`artisan would understand from these facts that the purpose of applying heat and
`
`pressure during the lamination process is to get the adhesive to flow in order to
`
`obtain intimate contact between the adhesive and surface features of the surfaces
`
`being laminated in order to create the laminated article. (Ex. 1018 at ¶ 15.)
`
`3.
`
`The diameter of the polymer molecules of the adhesive in
`Kuwahara would be below 500 Angstroms
`
`Patent Owner argues that the discrete islands could not be in Kuwahara’s
`
`adhesive because the molecular weight, and hence the length of the polymer
`
`chains, of the adhesive are too large to physically fit in the 500 Angstrom spacing
`
`between the discrete islands. (Response at 25.) Again, Patent Owner does not
`
`mention spacing up to 5000 Angstroms as disclosed in Kuwahara (Ex. 1007) at
`
`4:6-7. Moreover, Patent Owner fundamentally errs by only considering the length
`
`of the chains and not the polymer diameter and mobility. (Ex. 1018 at ¶ 16.)
`
`Typical polymer molecules are very thin and flexible like cooked spaghetti.
`
`(Ex. 1018 at ¶ 17.) In a flowing adhesive, the huge number of polymer chains
`
`la-1231065
`
`9
`
`

`

`IPR2013-00149
`
`would be oriented in every conceivable direction. The chains that are aligned
`
`width-wise with the openings would, therefore, necessarily flow between the metal
`
`islands. (Id. at ¶ 17.)
`
`This is confirmed when the calculations are applied specifically to a vinyl
`
`chloride-vinyl acetate adhesive. (Ex. 1018 at ¶ 18.) As explained by Dr. Iezzi,
`
`App. CC to Ex. 1018 provides the cross-sectional area of poly-vinyl-chloride and
`
`poly-vinyl acetate and explains that the polymer chain diameter can be estimated
`
`by taking the square root of these diameters. (Id.) These calculations provide a
`
`polymer diameter of 5.2 Angstroms for poly-vinyl-chloride, and 7.7 Angstroms for
`
`polyvinyl acetate. (Id.) Even assuming that these polymer chains appear exactly
`
`side by side in a vinyl chloride-vinyl acetate adhesive, the total polymer chain
`
`diameter would be 12.9 Angstroms, considerably below both the 5000 and 500
`
`Angstrom spacing between the discrete islands disclosed in Kuwahara. (Id.)
`
`In short, the facts of Kuwahara completely undercut Patent Owner’s attorney
`
`argument. Kuwahara discloses island spacing of up to 5000 Angstroms – a fact
`
`ignored by Patent Owner’s attorney argument. Moreover, Kuwahara discloses
`
`polymer chains whose diameter would be well below 500 Angstroms – another
`
`fact ignored by Patent Owner’s attorney argument.
`
`la-1231065
`
`10
`
`

`

`IPR2013-00149
`
`D. Kuwahara’s Roller Coats The Liquid Resin Onto The Metallized
`Layer
`
`In response to Dr. Iezzi’s statement that “the adhesive is applied on top of
`
`the discontinuous metal layer,” Patent Owner states that Dr. Iezzi “is implying that
`
`a liquid is applied to the top of the metallized film as it might be oriented
`
`vertically, and consequently, gravity would cause the liquid to seep into the spaces
`
`between the islands of metal.” (Response at 27-28.)
`
`Dr. Iezzi never stated that gravity is the cause of the adhesive flowing across
`
`the surface and seeping into the space between the islands of metal. The term
`
`“top” was used relative to the structure in which metal islands are formed on
`
`Kuwahara’s PET layer. (Ex. 1018 at ¶ 19.) This term was not meant to identify
`
`any positioning with respect to coordinates external to the structure. (Id.)
`
`More importantly, the facts of Kuwahara establish that its adhesive would
`
`readily wet and flow into the spacings between islands. A liquid adhesive, such as
`
`disclosed in Kuwahara, sticks to the metal/PET laminate by its adhesive
`
`characteristics. Adhesives can be applied “upside down” by roll coating because
`
`the driving forces, such as (a) surface tension; (b) capillary action; (c) the
`
`adhesive’s polymer chain small molecular diameter, mobility, and orientation; and
`
`(d) intrinsic molecular inter-diffusion, cause the adhesive to spread into the
`
`crevices of a surface and obtain intimate contact with the surface. (Ex. 1018 at
`
`¶ 20.)
`
`la-1231065
`
`11
`
`

`

`IPR2013-00149
`
`These driving forces are present in Kuwahara. For example, with respect to
`
`the driving force of surface tension, a liquid adhesive “wets” a solid surface if it
`
`comes into with and spreads across all the exposed surfaces (including the exposed
`
`surfaces between the islands). (Ex. 1018 at ¶ 21.) A skilled artisan would have
`
`known that for a liquid to wet a solid surface, the surface tension of the liquid must
`
`be lower than the surface tension of the solid, and that metals have a high surface
`
`tension relative to adhesives and are easily coated by polymer adhesives and
`
`coatings. (Ex. 1018 at ¶ 22.)
`
`As explained by Dr. Iezzi, the surface tension of the tin metal islands in
`
`Kuwahara is approximately 587 dyne/cm. (Ex. 1018 at ¶ 23.) The surface tension
`
`of vinyl chloride is 41.9 dyne/cm, and of vinyl acetate is 36.5 dyne/cm. (Ex. 1018
`
`at ¶ 24.) Thus, the vinyl chloride-vinyl acetate adhesive of Kuwahara will readily
`
`wet and flow into the metal islands. Patent Owner also offers a scenario where
`
`solvent may be used to dissolve the adhesive. (Response at 14.) Typical solvents
`
`used for adhesives have much lower surface tension (about half) than the vinyl
`
`chloride-vinyl acetate adhesive. Therefore, if the adhesive of Kuwahara was
`
`dissolved in solvent, the surface tension of the adhesive-solvent mixture would be
`
`even lower and interact with the metal islands and flow into the spaces between the
`
`metal islands even more. (Ex. 1018 at ¶ 25.)
`
`la-1231065
`
`12
`
`

`

`IPR2013-00149
`
`With respect to the driving force of capillary action, it too would facilitate
`
`the flow of the adhesive into the small space between the metal islands. Capillary
`
`action is “[t]he attraction between molecules, similar to surface tension, which
`
`results in the rise of a liquid in small tubes or fibers, as can occur in filled
`
`compounds or reinforced plastics.” (Ex. 1018 at ¶ 26; App. GG.) Thus, Patent
`
`Owner’s depiction of the Kuwahara’s adhesive possibly being applied to the
`
`bottom side of the part being coated is irrelevant, because the adhesive would flow
`
`into the small space between the metal islands due to capillary forces alone.
`
`(Ex. 1018 at ¶ 26.)
`
`Finally, after applying the adhesive to the metal island layer, and stacking a
`
`polyvinylchloride film on top of the adhesive, Kuwahara discloses applying heat
`
`and pressure to the structure to film a lamination. (Ex. 1007 at 5:21-22.) The heat
`
`and pressure applied during the lamination procedure would further drive the
`
`adhesive into any unfilled spaces between the islands. (Ex. 1018 at ¶ 27.)
`
`Thus, Patent Owner’s arguments as to the placement of adhesive
`
`inaccurately presents Dr. Iezzi’s testimony, is wrong given the difference in
`
`surface tension between the adhesive and metal islands and ultimately irrelevant
`
`given that adhesive would flow between the metal islands due to capillary forces.

`
`E. Kuwahara Does Not Teach Away
`
`Patent Owner argues that Kuwahara teaches away from the presence of
`
`adhesive between the islands, because residual solvent would permit electricity to
`
`flow between the metal islands, which is to be avoided in Kuwahara. (Response at
`
`30-31.) As a preliminary matter, teaching away is inapplicable to an anticipation
`
`analysis. Celeritas Techs., Ltd. v. Rockwell Int'l Corp., 150 F.3d 1354, 1361 (Fed.
`
`Cir. 1998). In addition, the argument makes no sense, because the adhesive would
`
`still electrically connect the metal islands even if it was on top, as the Patent
`
`Owner argues. Moreover, it is known that most of the solvent would have
`
`evaporated during the lamination process. (Ex. 1018 at ¶ 28.) One skilled in the
`
`art would understand that the small amount of solvent that remained would not
`
`have turned a non-conducting polymer adhesive into a conductor as Patent Owner
`
`argues. (Id.)
`
`F.
`
`The Adhesive Would Flow
`
`At page 32 of the Response, the Patent Owner refers to Dr. Iezzi’s testimony
`
`as “unsupported opinion testimony.” These statements are incorrect, because Dr.
`
`Iezzi’s testimony was based on the facts disclosed in Kuwahara and thus was fully
`
`supported.
`
`As discussed above, 1) Kuwahara discloses that the adhesive is roll coated,
`
`which the skilled artisan would understand as a liquid adhesive with a viscosity
`
`la-1231065
`

`
`

`

`IPR2013-00149
`
`low enough to be a mobile liquid; 2) the diameter of the polymer molecules for the
`
`adhesive disclosed in Kuwahara is significantly less than the 500 Angstrom voids
`
`used in the examples of Kuwahara and even more significantly less than the 5000
`
`Angstrom voids also disclosed in Kuwahara; 3) the “wetting” action of the
`
`adhesive and capillary action would pull the adhesive into these relatively large
`
`pores as disclosed in Kuwahara; and 4) Kuwahara discloses applying heat and
`
`pressure during the lamination procedure, which would further drive the adhesive
`
`into any unfilled spaces between the islands. (Ex. 1018 at ¶ 30.) Thus, by a
`
`preponderance of evidence, Kuwahara necessarily discloses that the discrete
`
`islands are in adhesive to the skilled artisan.
`
`IV. CONCLUSION
`
`For at least the foregoing reasons, as well as those set forth in its Petition
`
`dated February 15, 2013, Petitioner respectfully requests the cancellation of claims
`
`1-3, 8, 10, 16-19, 21 and 25-33, 35, and 36 of the '138 patent.
