MEMORANDUM OPINION AND ORDER

Shenzhen Kean Silicone Product Co., Ltd. (“Shenzhen Kean” or “Plaintiff”) brings suit against Moon and Stars Online Inc. (“Moon and Stars”) and Shenzhen Shenchenxing Trading Co., Ltd. (“Shenzhen Shenchenxing”) (together, “Defendants”) for patent infringement. Defendants move to dismiss.1 Plaintiff moves for a preliminary injunction.2 For the reasons discussed below, both motions are denied. Background Plaintiff is the owner of United States Design Patent No. D975,787 (the “’787 Patent”), which was issued by the United States Patent and Trademark Office on January 17, 2023. The ’787 Patent covers the ornamental design of Plaintiff’s toy product:

1 Defendants Moon and Stars and Shenzhen Shenchenxing jointly filed a motion to dismiss [36]. See ECF 36. Defendant Shenzhen Shenchenxing subsequently filed a separate motion to dismiss. See ECF 39. The two motions to dismiss are identical. As such, Shenzhen Shenchenxing’s separate motion to dismiss is stricken as duplicative. 2 Defendants Moon and Stars and Shenzhen Shenchenxing jointly filed a brief in opposition to Plaintiff’s motion for preliminary injunction. See ECF 35. Defendant Shenzhen Shenchenxing subsequently filed a separate brief in opposition. See ECF 38. The two opposition briefs are identical. As such, Shenzhen Shenchenxing’s separate brief in opposition is stricken as duplicative. (| DoOoOk

ECF 1-1 at Fig. 1; ECF 1 at ¥ 8. Plaintiff alleges that Defendants sell products that infringe on the °787 Patent through storefronts on various online marketplaces. See ECF 1 at 15. Motion to Dismiss Defendants move to dismiss Plaintiff's complaint under Federal Rule of Civil Procedure 12(b)(6), arguing that Plaintiff has failed to state a claim upon which relief can be granted in light of Defendants’ affirmative defenses. A. Legal Standard Under Federal Rule of Civil Procedure 8(a)(2), a complaint must provide “a short and plain statement of the claim showing that the pleader is entitled to relief.” Through this statement, defendants must be provided with “fair notice” of the claim and the basis for it. Bell Atl. Corp. v. Twombly, 550 U.S. 544, 555 (2007). This means that the complaint must contain factual allegations sufficient to “state a claim to relief that is plausible on its face.” Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009). Although a plaintiff “need not plead detailed factual allegations to survive a motion to dismiss, she still must provide more than mere labels and conclusions or a formulaic recitation of the elements of a cause of action for her complaint to be considered adequate.” Bell v. City of Chicago, 835 F.3d 736, 738 (7th Cir. 2016). In deciding a motion to dismiss under Federal Rule

of Procedure 12(b)(6), courts must “accept all well-pleaded facts as true and draw reasonable inference in the plaintiff’s favor.” Roberts v. City of Chicago, 817 F.3d 561, 564 (7th Cir. 2016). Design patents protect a “new, original and ornamental design for an article of manufacture.” 35 U.S.C § 171. To survive a motion to dismiss a design patent infringement claim,

a plaintiff need only: “(i) allege ownership of the patent, (ii) name each defendant, (iii) cite the patent that is allegedly infringed, (iv) state the means by which the defendant allegedly infringes, and (v) point to the sections of the patent law invoked.” Hall v. Bed Bath & Beyond, Inc., 705 F.3d 1357, 1362 (Fed. Cir. 2012). Design patents are presumed valid. See Ethicon Endo-Surgery, Inc. v. Covidien, Inc., 796 F.3d 1312, 1328 (Fed. Cir. 2015). However, alleged infringers may rebut this presumption by proving facts supporting a determination of invalidity “by clear and convincing evidence.” See id. B. Discussion Defendants move to dismiss based on three invalidity defenses: they argue that (a) the ’787 Patent claims primarily functional features; (b) the claimed design is anticipated by prior art; and

(c) prior art renders the claimed design obvious. See ECF 36 at 2. Their arguments fail on procedural grounds and on the merits. 1. Standard of Review Defendants insist that their motion is brought under Rule 12(b)(6), not Rule 56. See ECF 45 at 2-3. But Defendants rely on evidence beyond the pleadings in support of their arguments— namely, prior art of United States Patent Nos. 5,413,551, issued in 1995, (the “’551 Patent”) and 6,432,071 B1, issued in 2002 (the “’071 Patent”). See ECF 36-1; ECF 36-2. In general, a court deciding a Rule 12(b)(6) motion may consider only the pleadings and any “written instruments” attached to the complaint. See Rosenblum v. Travelbyus.com Ltd., 299 F.3d 657, 661 (7th Cir. 2002) (citing Fed. R. Civ. P. 10(c)). Otherwise, if “matters outside the pleadings are presented to and not excluded by the court, the motion must be treated as one for summary judgment under Rule 56.” Fed. R. Civ. P. 12(d). There are two exceptions to this rule. First, a court may take judicial notice of facts that are part of the public record and which are “not subject to reasonable

dispute.” Fed. R. Evid. 201(b). Second, under the incorporation-by-reference doctrine, a court may consider documents “referred to in the plaintiff’s complaint and [which] are central to his claim.” Brownmark Films, LLC v. Comedy Partners, 682 F.3d 687, 691 (7th Cir. 2012) (cleaned up). The decision to consider extraneous documents and/or convert a motion to dismiss to one for summary judgment is within the district court’s discretion. See Hecker v. Deere & Co., 556 F.3d 575, 583 (7th Cir. 2009) (abrogated on other grounds). Neither doctrine permits the Court to draw the inferences Defendants seek from the prior art of the ’551 and ’071 Patents. First, incorporation-by-reference does not apply, as the ’551 and ’071 Patents are not referenced in or attached to Plaintiff’s complaint. Second, the Court may take judicial notice of the existence of the ’551 and ’071 Patents, but cannot take judicial notice of the
