Jonathan Day, et al. v. Advanced Micro Devices, Inc.

Summary

The United States District Court for the Northern District of California granted AMD's motion to dismiss the plaintiffs' claims, with leave to amend. The court dismissed the negligence claim under the economic loss rule, the unjust enrichment claim for pleading deficiencies, and the implied warranty claims as insufficient to show unmerchantability. The court also found that the plaintiffs had not clearly identified viable theories under the Illinois and West Virginia consumer protection statutes and allowed 21 days to amend.

Holdings

1. The negligence claim was dismissed because it was barred by the economic loss rule. Plaintiffs did not adequately allege physical damage to their computers sufficient to invoke the damage-to-other-property exception.
2. The unjust enrichment claim was dismissed because plaintiffs did not provide a representative state's law for their purported nationwide class and did not allege why legal remedies were inadequate. Under California law, an unjust enrichment theory must be pleaded in the alternative and accompanied by an allegation that legal remedies are inadequate.
3. The claims for breach of the implied warranty of merchantability were dismissed because the allegations about the frequency and duration of the stuttering were too abstract and insufficient to suggest that the CPU was unmerchantable.
4. The consumer-protection claims were dismissed because the complaint did not clearly identify the legal theories plaintiffs were pursuing or adequately present the governing law. If plaintiffs were pursuing fraud-based claims, the allegations of pre-sale knowledge, actionable representations, and reliance were inadequate; if they were pursuing unfair or unethical-practices theories, they had not adequately presented the relevant law or elements.

Questions Presented

1. Whether the negligence claim was barred by the economic loss rule because plaintiffs failed to adequately allege physical damage to other property.
2. Whether the unjust enrichment claim was adequately pleaded where plaintiffs purported to represent a nationwide class without offering a representative state's law and did not allege that legal remedies were inadequate.
3. Whether the allegations concerning the frequency and duration of processor stuttering plausibly suggested that the CPU was unmerchantable.
4. Whether the Illinois and West Virginia consumer-protection claims were adequately pleaded when plaintiffs did not clearly identify whether they pursued fraud-based or unfair-practices theories and did not adequately plead the elements of either theory.
