Shortly thereafter, discovery commenced. Over the next ten months, the Parties exchanged substantial fact and expert discovery, including the production of documents, the exchange of multiple sets of interrogatories, the depositions of Plaintiffs, and the disclosure of expert reports. See Exhibit 1, Declaration of Todd Logan (“Logan Decl.”) ¶¶ 3-4.
Specifically, the Parties collectively produced over 6,000 pages of documents, collectively responded to fifty-five (55) interrogatories, conducted full-day depositions of Tony Dickey and Paul Parmer on January 8, 2018, and January 16, 2018, respectively, and Defendant disclosed the expert reports of Dr. Thomas Conte, Dr. Dominique Hanssens, Kishore Mulchandani, and Justin McCrary. See Dkt. 122. The Parties also engaged in several discovery disputes, including motion practice related to the disclosure and filing of expert reports. See Dkt. 110; Dkt. 111
Following these discovery efforts, on March 27, 2018, Plaintiffs filed a Motion for Class Certification, which sought to certify a class of consumers under California’s Unfair Competition Law and False Advertising Law. Dkt. 118. Approximately nine months later, the Court granted Plaintiff’s motion on January 17, 2019 and certified a class comprised of “all individuals who purchased one or more of the following AMD computer chips either (1) while residing in California or (2) after visiting the AMD.com website: FX-8120, FX-8150, FX-8320, FX-8350, FX-8370, FX-9370, and FX-9590.
In the months following the Court’s ruling, the Parties began marching towards summary judgment briefing. Plaintiffs vetted more than a dozen potential technical experts and ultimately formally engaged two leading experts on CPU microarchitecture, Dr. Phillip Emma and Dr. Vojin Oklobdzija, who in total produced four preliminary written expert reports—two affirmative reports and two rebuttal reports. Logan Decl. ¶ 4. On March 28, 2019 and then on June 3, 2019, amended case schedules were entered, under which fact discovery would close in September 2019. Dkt. 135.
