Opinion

UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF OHIO WESTERN DIVISION

Samuel Stamping Technologies, LLC, Case No. 3:20-cv-1011

Plaintiff,

v. MEMORANDUM OPINION AND ORDER

Therma-Tru Corp.,

Defendant.

I. INTRODUCTION Defendant Therma-Tru Corporation filed a motion for partial summary judgment, arguing Plaintiff Samuel Stamping Technologies, LLC (“SST”), should be estopped from arguing that the relevant article of manufacture in this case is a door rather than a door skin. (Doc. No. 116). SST opposed Therma-Tru’s motion, (Doc. No. 118), and Therma-Tru filed a brief in reply. (Doc. No. 119). SST then filed a motion to exclude consideration of certain arguments Therma-Tru offered in its reply brief or, in the alternative, for leave to file a sur-reply brief. (Doc. No. 120). Therma-Tru opposed that motion. (Doc. No. 121). For the reasons stated below, I deny both motions. II. BACKGROUND SST alleges Therma-Tru infringed upon three design patents it holds. Therma-Tru challenged the patents as unenforceable due to indefiniteness, but a jury concluded Therma-Tru had not carried its burden to show by clear and convincing evidence that a person of ordinary skill in the art would be unable to understand the scope of the design patents with reasonable certainty. (Doc. Nos. 70, 71, and 72). Therma-Tru argues that, to reach those conclusions, the jury had to conclude “that the ordinary designer would . . . view the designs as door skins laying down not as doors standing up,” and, therefore, the article of manufacture as contemplated by SST’s patents is a door skin rather than a door. (Doc. No. 116 at 5). The parties agree that the determination of whether the article of

manufacture is a door or a door skin is integral to the proper calculation of disgorgement damages if Therma-Tru is found to have infringed upon SST’s patents. (Id.; Doc. No. 118 at 14-15). III. STANDARD Summary judgment is appropriate where “the movant shows that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.” Fed. R. Civ. P. 56(a). The moving party bears the initial responsibility of “informing the district court of the basis for its motion, and identifying those portions of ‘the [record] . . . ,’ which it believes demonstrate the absence of a genuine issue of material fact.” Celotex Corp. v. Catrett, 477 U.S. 317, 323 (1986). The movant may meet this burden by demonstrating the absence of evidence supporting one or more essential elements of the non-movant’s claim. Id. at 323-25. Once the movant meets this burden, the opposing party “‘must set forth specific facts showing that there is a genuine issue for trial.’” Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 250 (1986) (quoting Fed. R. Civ. P. 56(e)).

When the burden of production has so shifted, the party opposing summary judgment cannot rest on its pleadings or merely reassert its previous allegations. It is not sufficient “simply [to] show that there is some metaphysical doubt as to the material facts.” Matsushita Elec. Indus. Co. v. Zenith Radio Corp., 475 U.S. 574, 586 (1986). Rather, Rule 56(e) “requires the nonmoving party to go beyond the pleadings” and present some type of evidentiary material in support of its position. Celotex, 477 U.S. at 324; see also Harris v. Gen. Motors Corp., 201 F.3d 800, 802 (6th Cir. 2000). Summary judgment must be entered “against a party who fails to make a showing sufficient to establish the existence of an element essential to that party’s case, and on which that party will bear the burden of proof at trial.” Celotex, 477 U.S. at 322. “In considering a motion for summary judgment, the Court must view the facts and draw all reasonable inferences therefrom in a light most favorable to the nonmoving party.” Williams v.

Belknap, 154 F. Supp. 2d 1069, 1071 (E.D. Mich. 2001) (citing 60 Ivy Street Corp. v. Alexander, 822 F.2d 1432, 1435 (6th Cir. 1987)). But “‘at the summary judgment stage the judge’s function is not himself to weigh the evidence and determine the truth of the matter.’” Wiley v. United States, 20 F.3d 222, 227 (6th Cir. 1994) (quoting Anderson, 477 U.S. at 249). Therefore, “[t]he Court is not required or permitted . . . to judge the evidence or make findings of fact.” Williams, 154 F. Supp. 2d at 1071. The purpose of summary judgment “is not to resolve factual issues, but to determine if there are genuine issues of fact to be tried.” Abercrombie & Fitch Stores, Inc. v. Am. Eagle Outfitters, Inc., 130 F. Supp. 2d 928, 930 (S.D. Ohio 1999). Ultimately, I must determine “whether the evidence presents a sufficient disagreement to require submission to a jury or whether it is so one-sided that one party must prevail as a matter of law.” Anderson, 477 U.S. at 251-52; see also Atchley v. RK Co., 224 F.3d 537, 539 (6th Cir. 2000). IV. ANALYSIS A. JUDICIAL ESTOPPEL

“‘[T]he doctrine of judicial estoppel bars a party from (1) asserting a position that is contrary to one that the party has asserted under oath in a prior proceeding, where (2) the prior court adopted the contrary position “either as a preliminary matter or as part of a final disposition.”’” Shufeldt v. Baker, Donelson, Bearman, Caldwell & Berkowitz, PC, 855 F. App’x 239, 243 (6th Cir. 2021) (quoting Browning v. Levy, 283 F.3d 761, 775 (6th Cir. 2002) (further quoting Teledyne Indus., Inc. v. NLRB, 911 F.2d 1214, 1218 (6th Cir. 1990))). “The essential function of judicial estoppel is to prevent intentional inconsistency; the object of the rule is to protect the judiciary, as an institution, from the perversion of judicial machinery.” Edwards v. Aetna Life Ins. Co., 690 F.2d 595, 599 (6th Cir. 1982). Courts should apply judicial estoppel “with caution to ‘avoid impinging on the truth-seeking function of the court, because the doctrine precludes a contradictory position without examining the truth of either statement.’” Eubanks v. CBSK Fin. Grp., Inc., 385 F.3d 894, 897 (6th Cir. 2004)

(quoting Teledyne Indus., 911 F.2d at 1218). Therma-Tru contends the doctrine of judicial estoppel prohibits SST from taking what Therma-Tru sees as contradictory positions – first, during the jury trial on the issue of indefiniteness, that the article of manufacture is a door skin and second, now asserting that the article of manufacture is a door.
