9 Plaintiff,

ORDER GRANTING IN PART AND 10 v. DENYING IN PART MOTION TO EXCLUDE OPINIONS OF DEREK 11 SHARKNINJA OPERATING LLC., KING 12 Defendant.

13 Plaintiff Jessica Ann Bettencourt suffered hand lacerations when the blade assembly 14 fell out of a blender manufactured by Defendant SharkNinja Operating, LLC 15 (“SharkNinja”). Plaintiff sued SharkNinja, alleging strict and negligent products liability 16 due to SharkNinja’s failure to provide a locking mechanism for the blade assembly. Am. 17 Compl. (dkt. 12). SharkNinja moves to exclude the testimony of Plaintiff’s expert. Mot. 18 (dkt. 44). As explained below, the Court DENIES the motion with respect to Opinion Nos. 19 1 and 2 and GRANTS the motion with respect to Opinion Nos. 3, 4, and 5. 20 I. BACKGROUND 21 A. Factual History 22 SharkNinja designs and manufactures Ninja BL610 blenders (“Blender”). Am. 23 Compl. ¶ 8. The Blender consists of three components: (1) a motor base; (2) a pitcher; and 24 (3) a stacked blade assembly. Id. ¶ 17. The blade assembly, which runs the length of the 25 pitcher, does not lock into place and is not otherwise secured when the lid is off or 26 unlocked. Id. ¶¶ 17–19.

Kaiser a 16 || Decl. Ex. B (‘Rimkus Report’) (dkt. 44-3) at 8; Owner’s Guide at 10. There are two ways 2 17 || by which users can pour blended contents out of the blender. The first is by pouring the s 18 || contents out through the lid’s “pour spout.” Owner’s Guide at 11.

Owner’s Guide at 11.

z 18 Plaintiff used the Blender to make a smoothie. Kaiser Decl. Ex. H (“PI.’s Dep. Vol. 19 IT’) (dkt. 44-9) at 24:18-19. After blending the ingredients, Plaintiff tilted the pitcher to 20 pour the smoothie into a cup. Id. at 28:10—12. Plaintiff does not remember whether the lid 21 was locked, but remembers that she did not remove the lid. Id. at 28:13—15, 32:22—25— 22 33:1. According to SharkNinja’s expert, the lid cannot fall off of the pitcher if it 1s 23 properly locked. Rimkus Report at 16. The lid fell off, the blade fell out of the pitcher, 24 and Plaintiff's hand was cut. Pl.’s Dep. Vol. II at 29:2—9. 25 B. Procedural History 26 Plaintiff filed suit, claiming strict and negligent products liability. See generally 27 Compl. (dkt. 1). Plaintiff amended her complaint, still claiming strict and negligent 28

1 products liability. See Am. Compl. ¶¶ 32–42. Plaintiff also submitted an expert report 2 from Derek King in support of her defective design claim. See Kaiser Decl. Ex. K (“King 3 Report”) (dkt. 44-12). SharkNinja filed a motion for summary judgment and a motion to 4 exclude Mr. King’s testimony. MSJ (dkt. 45)2; Mot. In its motion for summary judgment, 5 SharkNinja contends, among other things, that Plaintiff’s claims fail because she can 6 neither satisfy the prima facie requirements for defective design nor present evidence of 7 causation without admissible expert testimony. MSJ at 7–8.3 8 C. Derek King’s Testimony 9 Plaintiff’s expert, Derek King, holds an M.S. in Electrical Engineering from Ohio 10 University and a B.S. in Mechanical Engineering from University of California, Berkeley. 11 King Report at 3. He has worked as an engineer for Berkeley Engineering and Research 12 (“BEAR”) since 2009 in the areas of failure analysis, design, and risk assessment of 13 consumer and industrial equipment, including consumer blenders. Id. 14 Currently, the Blender’s blade assembly is only secured to the pitcher when the lid 15 is locked. See id. at 5. As an alternative design, Mr. King proposes a “simple snap or 16 locking mechanism” to hold the blade assembly in place when the lid is off or unlocked, to 17 prevent lacerations from falling blades. Id. at 6. He provides the KitchenAid 3.5 Cup 18 Food Chopper (“KitchenAid Chopper”) as an example. Id. at 8. Both products are used to 19 pulverize food and have a detaching blade assembly that slides over a fixture in the pitcher. 20 Id. They look like this: 21 22 23 24 25 26 2 The Court addresses the summary judgment motion in a separate order. 27 3 This order cites to Defendant’s summary judgment brief by referencing the efiling page 1

18 At the end of his report, Mr. King provides five opinions, all of which SharkNinja 19 || seeks to exclude in the present motion: 20 (1) the design of the Blender is defective because the blade assembly can 21 “unintentionally separate” from the pitcher and there are safer alternative 22 designs available; 23 (2) the warnings in connection with this product and the prior recalls of the 24 BL660—a different SharkNinja product with a similarly unsecured blade 25 assembly— show that SharkNinja was aware of the hazard from loose 26 blades; 27 28

1 (3) SharkNinja’s Design Failure Modes and Effects Analysis (“DFMEA”)4 of 2 the Blender did not address the hazard from loose blades falling out of the 3 pitcher; 4 (4) if SharkNinja’s DFMEA had addressed the hazard from loose blades falling 5 out of the pitcher, then SharkNinja would have implemented a locking 6 mechanism; and 7 (5) Plaintiff’s injury was likely caused by “the pitcher being tipped over without 8 the lid,” and a locking mechanism would have likely prevented the injury. 9 King Report at 15. 10 Mr. King’s expert report appears to be based largely on a prior one submitted by his 11 colleagues at BEAR in the Welch v. SharkNinja Operating LLC case. See No. 12 21CV00123, 2021 WL 6332889 (S.D. Tex. May 24, 2021) (alleging that the loose blade 13 assembly of a different SharkNinja product caused severe hand lacerations when the user 14 accidentally knocked the product off the counter while packing); Kaiser Decl. Ex. I 15 (“Welch Report”) (dkt. 44-10). In some parts of his report in this case, Mr. King 16 accurately recites the facts of this case. See King Report at 3 (“[Plaintiff] suffered a severe 17 hand laceration as a result of the stacked blade assembly separating from the blender cup 18 when she was pouring the smoothie out into a separate cup to drink from”). Mr. King also 19 provides photos of the correct SharkNinja product that injured Plaintiff, not the product at 20 issue in the Welch Report. See id. at 5–8; Welch Report at 5. However, in other parts of 21 his report in this case, Mr. King provides inconsistent facts that appear to be copied from 22 the Welch Report: 23 King Report in this case Welch Report 24 “Ms.
