`
`IN THE UNITED STATES DISTRICT COURT
`FOR THE EASTERN DISTRICT OF TEXAS
`MARSHALL DIVISION
`









`
`
`
`MEMORANDUM ORDER
`
`GREE, INC.,
`
` Plaintiff,
`
`v.
`
`SUPERCELL OY,
`
` Defendant.
`
`
`Case No. 2:19-cv-00310-JRG-RSP
`
`Before the Court is Defendant Supercell Oy’s Motion to Strike Plaintiff GREE, Inc.’s
`
`Technical Expert, Dr. Robert Akl, for Improper Claim Construction. Dkt. No. 115. Supercell’s
`
`Motion seeks to strike opinions of Dr. Akl that allegedly rely upon an improper claim construction
`
`of “character.”
`
`I.
`
`BACKGROUND
`
`On October 13, 2020, the Court issued a Claim Construction Order construing disputed
`
`claim terms of U.S. Patent No. 10,076,708 (the “’708 patent”) and No. 10,413,832 (the “’832
`
`patent”). Dkt. No. 84. At issue in the present motion is the Court’s construction of “character” as
`
`meaning “symbol.” See Id. at 19. The Court noted in the Claim Construction Order that “the patents
`
`provide ‘character’ as an alternative to ‘patterns’ and ‘colors’ to denote the rarity of an item.” Id.
`
`at 18. The Court also pointed to the ’708 Patent’s specification at col.9 ll.16–67 and the ’708
`
`Patent’s File Wrapper April 26, 2018 Amendment to discuss the distinction between “pattern” and
`
`“character.” Id. The ‘’708 Patent specification provides:
`
`FIG. 7(a) illustrates an example of acquirable item information
`presented by the information presentation unit 12 in Embodiment 2.
`… Items are associated with the boxes 201 to 219 so that the
`respective counts of necessary acquisition attempts are 1 to 19. Each
`
`

`

`Case 2:19-cv-00310-JRG-RSP Document 179 Filed 01/23/21 Page 2 of 5 PageID #: 7009
`
`box is displayed with a pattern that differs in accordance with the
`item type of the corresponding item.
`
`As illustrated in the example in FIG. 7(a), when the numerical value
`of the item type is at least a predetermined value, the pattern shown
`in box 204 and the like is displayed. …
`
`The patterns for displaying the boxes 201 to 219 are not limited to
`these examples. The boxes 201 to 219 may be painted a
`predetermined color in accordance with the item type, or a
`predetermined icon, character, or the like may be displayed in the
`boxes 201 to 219.
`
`’708 Patent col. 9 ll.16–67. The ’708 Patent File Wrapper provides:
`
`The claims are further amended to recite the feature of “at least one
`of the cells including a character which indicates a rarity value of an
`item associated with the at least one of the cells.” This feature may
`be understood with reference to the publication of this application,
`with paragraph [0089] disclosing that each cell may have a
`“character” in lieu of the “pattern” in accordance with the “item
`type” as in paragraph [0087], and paragraph [0040] describing the
`“item type” as representing the rarity value.”
`
`Dkt. No. 65-3 at 5. The Court found that “[o]n balance, the term ‘symbol’ adequately captures the
`
`distinction between ‘character’ and the other forms described in the patent for denoting the rarity
`
`attribute of an item.”
`
`II.
`
`LEGAL STANDARDS
`
`Federal Rule of Evidence 702 permits expert witness testimony if:
`
`“(a) the expert’s scientific, technical, or other specialized knowledge
`will help the trier of fact to understand the evidence or to determine
`a fact in issue; (b) the testimony is based on sufficient facts or data;
`(c) the testimony is the product of reliable principles and methods;
`and (d) the expert has reliably applied the principles and methods to
`the facts of the case.”
`
`Fed. R. Evid. 702. The district court “ensur[es] that an expert’s testimony both rests on a reliable
`
`foundation and is relevant to the task at hand.” Daubert v. Merrell Dow Pharm. Inc., 509 U.S. 579,
`
`579-80 (1993). Relevance is a low bar. Evidence is relevant if: (a) it has any tendency to make a
`
`
`
`2 / 5
`
`

`

`Case 2:19-cv-00310-JRG-RSP Document 179 Filed 01/23/21 Page 3 of 5 PageID #: 7010
`
`fact more or less probable than it would be without the evidence; and (b) the fact is of consequence
`
`in determining the action. Fed. R. Evid. 401.
`
`Regarding reliability, part of that inquiry is whether the data utilized in the methodology is
`
`sufficiently tied to the facts of the case. Kumho Tire Co., Ltd. v. Carmichael, 526 U.S. 137, 150
`
`(1999). The burden is on the party offering the expert testimony to establish admissibility by a
`
`preponderance of the evidence. Moore v. Ashland Chem., Inc., 151 F.3d 269, 276 (5th Cir. 1998)
`
`(en banc).
`
`However, “the question of whether the expert is credible or the opinion is correct is
`
`generally a question for the fact finder, not the court.” Summit 6, LLC v. Samsung Elecs. Co., 802
`
`F.3d 1283, 1296 (Fed. Cir. 2015), citing Apple Inc. v. Motorola, Inc., 757 F.3d 1286, 1314 (Fed.
`
`Cir. 2014), overruled on other grounds by Williamson v. Citrix Online, LLC, 792 F.3d 1339 (Fed.
`
`Cir. 2015) (en banc). “Vigorous cross-examination, presentation of contrary evidence, and careful
`
`instruction on the burden of proof are the traditional and appropriate means of attacking shaky but
`
`admissible evidence.” Daubert, 509 U.S. at 596.
`
`III. ANALYSIS
`
`Supercell argues that Dr. Akl’s expert report in paragraphs 86 and 147 concerning element
`
`1-B of the ’708 Patent and element 3 of the ’832 Patent ignores the Court’s construction of the
`
`term character by “improperly draft[ing] the Court’s construction from the noun ‘symbol’ to the
`
`adjective ‘symbolic.’” Dkt. No. 115 at 5. Supercell asks the Court to “strike Dr. Akl’s argument
`
`that ‘[t]he visual depiction of the shapes and colors of the borders of the cards in Clash Royale . .
`
`. is symbolic of the relative rarity of those cards.” Id. (citing Dkt. No. 115-2 at ¶¶ 86, 147).

`

`

`Case 2:19-cv-00310-JRG-RSP Document 179 Filed 01/23/21 Page 4 of 5 PageID #: 7011
`
`
`
`Supercell asserts that “equating the ‘colors of the borders of the cards in Clash Royale’ as
`
`a ‘character’ “runs afoul of the Court’s claim construction order.” The paragraphs in question
`
`provide:
`
`The visual depiction of the shapes and colors of the borders of the
`cards in Clash Royale, as explained above, is symbolic of the
`relative rarity of those cards, and the additional textual display of
`the card’s rarity in the Clash Royale is another example of a
`character to indicate rarity.
`
`Dkt. No. 115-2 at ¶¶ 86, 147. Supercell takes issue with the use of the term “symbolic” instead of
`
`“symbol,” and claims that Dr. Akl is arguing that the colors of the borders alone—omitting “the
`
`shapes and” immediately prior to “colors of the borders”—are characters. Dkt. No. 115 at 6.
`
`
`
`Supercell then points to Dr. Akl’s deposition where he states that “a visual depiction of
`
`shapes and colors of the borders of the card is symbolic of the relative rarity of the card, and that
`
`meets the Court's construction of pattern, which means symbol -- of character, sorry -- which
`
`means symbol.” Id. (citing Dkt. No. 115-ExB at 190:3-8). Supercell argues that “Dr. Akl’s opinion
`
`that the ‘colors of the borders of the cards in Clash Royale’ are indicative of a ‘character’ is
`
`contrary to the Court’s claim construction order.” Id. The Court disagrees.
`
`
`
`Supercell disputes the use of the word “symbolic” instead of “symbol,” an adjective and
`
`noun version of the same concept, while not fully presenting Dr. Akl’s opinion. Regarding the
`
`assertion that Dr. Akl is arguing that the color of the borders alone is a character, Supercell leaves
`
`out the actual subject of the incompletely quoted sentence, which is clearly “[t]he visual depiction,”
`
`modified by “of the shapes and colors of the borders of the cards.”
`
`The Court reads Dr. Akl’s opinion as asserting that “the visual depiction of the shapes and
`
`colors of the borders of the cards,” in its entirety, falls within the court’s construction of character
`
`as “symbol” in the same way that the visual depiction of a red equilateral triangle with one of its
`
`
`
`4 / 5
`
`

`
`edges aligned horizontally and one corner pointed downward with a smaller and similar white
`
`triangle oriented similarly collectively forms a symbol to yield right-of-way in a driving context.
`
`IV. CONCLUSION
`
`After due consideration, the Court DENIES Supercell’s Motion.
