In one sentence

In Young v. Cree, Judge Rogers excluded an expert, denied class certification, and denied another expert challenge as moot.

Who this affects

Jeff Young, the proposed California consumer class, Cree, Inc., and the parties’ expert evidence. The order denied class certification but did not state that Young’s individual claims were dismissed.

What happened

In Young v. Cree, Inc., Jeff Young alleged that Cree made misleading claims about its LED lightbulbs’ lifespan, energy savings, and satisfaction guarantee. He sought to represent California consumers who bought the bulbs for personal use.

The court excluded Dr. Gary Allen’s opinions because his methods for grouping bulbs and predicting failures were not shown to be scientifically reliable. Without those opinions, the court found that Young had not shown a defect common to the proposed class; individual questions about whether bulbs failed, how they failed, how long they lasted, and what caused the failure would remain.

Judge Yvonne Gonzalez Rogers denied Young’s renewed motion for class certification, granted Cree’s motion to exclude Dr. Allen’s opinions, and denied as moot Cree’s motion concerning Dr. Stefan Boedeker. The court also denied Young’s administrative motions to seal.

Case
Young v. Cree, Inc. · No. 4:17-cv-06252
Judge

Date
Jan. 28, 2021

Background

Jeff Young brought a putative class action against Cree, Inc. He alleged that Cree’s marketing and labeling for consumer light-emitting-diode (LED) bulbs falsely or deceptively promised long product lifespans, energy and cost savings, and a 100% satisfaction guarantee. The amended complaint asserted claims under California’s Unfair Competition Law, False Advertising Law, and Consumers Legal Remedies Act, as well as claims for fraudulent misrepresentation and concealment, unjust enrichment, and breach of express and implied warranties.

Young purchased three 100-watt replacement dimmable LED bulbs in April 2015. He alleged that he reviewed representations about longevity, cost savings, and warranties, and that the bulbs burned out within six months to one year. He sought certification of a California class consisting of people who purchased Cree LED bulbs for end use, rather than resale, from March 2013 through the present.

The court had previously denied class certification without prejudice and denied related expert challenges as moot. On the renewed motion, Young relied mainly on Dr. Gary R. Allen’s report to show that Cree’s bulbs shared a common defect. Young also submitted a report from Dr. Stefan Boedeker concerning classwide economic losses and damages.

Expert-testimony ruling

The court applied a tailored version of the standard for expert evidence under Federal Rule of Evidence 702, commonly associated with Daubert. At the class-certification stage, the court considered whether the expert evidence was sufficiently reliable and useful for evaluating the requirements for certification.

Cree did not challenge Dr. Allen’s credentials. Instead, it challenged his methods. Dr. Allen grouped Cree bulbs into designs and broader design architectures based largely on packaging, photographs, and PDF images. He then tested approximately ten bulbs and extrapolated his conclusions to a much broader range of products, including products from different generations and with different wattages and components.

The court found that Dr. Allen had not shown that this grouping and extrapolation method was generally accepted in the relevant engineering community or based on accepted scientific principles. The method also grouped together products that could have materially different thermal characteristics. The court concluded that the method did not meet the required level of scientific rigor.

The court separately rejected Dr. Allen’s “Target Maximum” temperature methodology. Those temperature limits were based on his personal, conservative design preferences rather than industry standards, peer-reviewed research, or another objective source. The court also found that his analysis did not establish a causal link between the alleged defect and liability or quantify a specific failure rate. In addition, his analysis focused primarily on possible parametric failures—such as reduced light output, color changes, or flickering—while the claims alleged catastrophic failures in which bulbs stopped working.

The court also struck new material in Dr. Allen’s rebuttal report concerning on-off switching studies and statistical analysis of retailer return records. The court found that these opinions were not properly disclosed in the opening report, did not rebut opinions from Cree’s experts, and, as to the statistical analysis, had not been supported by evidence that Dr. Allen was qualified to conduct it.

The court therefore granted Cree’s motion to strike and exclude Dr. Allen’s opinions under Rule 702. The court denied as moot Cree’s motion to strike and exclude Dr. Boedeker’s opinions because Dr. Allen’s exclusion independently resolved the class-certification issue. The court also denied Young’s request to exclude a declaration from Jonathan Vollers and denied as moot his request concerning declarations from Yuan Frank Fang.

Class certification

Class certification requires satisfying the requirements of Federal Rule of Civil Procedure 23. The court focused on commonality, which asks whether class members share a significant issue capable of being resolved for the class as a whole.

The court found that Young’s theory of commonality depended on Dr. Allen’s opinions about a common overheating defect. After excluding those opinions, Young did not provide another method for showing why his bulbs failed or for proving a common defect across Cree’s multiple product lines and generations.

The court further held that determining whether Cree’s statements were false would require individual inquiries into whether each consumer’s bulb failed, the manner of any failure, how long it lasted, and the cause of the failure. Because Young had not established a common defect or another common method of proof, he failed to satisfy the commonality requirement. The court therefore denied the renewed motion for class certification and did not address the remaining Rule 23 requirements.

Other dispositions

The court denied Young’s two administrative motions to seal because Cree, which had designated the material as confidential or privileged, had not filed the declaration required to establish that the material was sealable.

The order terminated Docket Numbers 115, 116, 117, 118, and 127. It also set a February 26, 2021 compliance deadline and directed the parties to file a joint statement about case scheduling five business days before that deadline, unless the deadline was taken off calendar after compliance.
