On February 12, 2025, the Fourth Circuit Court of Appeals affirmed the decision of the United States District Court for the Middle District of North Carolina not to grant class certification in a 17-year-old lawsuit accusing Inmar Inc. of fixing shipping prices for coupon processing services.  Mr. Dee’s Inc. v. Inmar, Inc., No. 23-2165 (4th Cir. Feb. 12, 2025). 

On November 25th, 2024, U.S. Western District Court of Washington Judge Jamal N. Whitehead certified a class of approximately 32,000 game developers who accuse digital PC game distributor Valve Corp. of stifling competition in the Personal Computer (“PC”) game distribution market through its Steam platform.  Wolfire Games LLC, et al. v. Valve Corp., et al., Docket No. 2:23-mc-00037 (W.D. Wash. Apr 26, 2023). 

On May 4, 2023, the United States Court of Appeals for the Third Circuit unsealed its April 24, 2023, Opinion upholding the Eastern District of Pennsylvania’s denial of a motion to certify an indirect purchaser class of insurance plans and other end-payors allegedly injured by a “reverse payment” settlement that allegedly delayed the entry of a generic competitor to the brand-name prescription drug, Niaspan.  In Re:  Niaspan Antitrust Litigation, No. 21-2895 (3d Cir. Apr. 24, 2023).

On August 1, 2022, Judge John S. Tigar of the United States District Court for the Northern District of California certified a class of direct purchasers in a long-running antitrust action alleging that manufacturers of cathode ray tubes conspired to fix prices in violation of Section 1 of the Sherman Act.  The Court certified the class after concluding that plaintiffs’ claims were typical of the class and the sole defendant who has not settled with plaintiffs failed to identify any individualized issues that would predominate over issues common to the proposed class.

On May 27, 2022, in In Re Broiler Chicken Antirust Litigation, No. 16 C 8637, 2022 WL 1720468, at *10 (N.D. Ill. May 27, 2022), Judge Thomas M. Durkin of the United States District Court for the Northern District of Illinois certified classes of direct purchasers, indirect purchasers, and end-user consumers (together, “plaintiffs”) in a Sherman Act lawsuit alleging that major broiler chicken producers conspired to limit chicken production to boost prices.

On April 8, 2022, the United States Court of Appeals for the Ninth Circuit, sitting en banc, affirmed an earlier district court order that certified three subclasses of tuna purchasers in a class action lawsuit alleging that defendants violated federal and state antitrust laws.  Olean Wholesale Grocery Coop. Inc. v. Bumble Bee Foods LLC, No. 19-56514, 2022 WL 1053459 (9th Cir. Apr. 8, 2022).

On September 29, 2021, the United States Court of Appeals for the Ninth Circuit reversed a district court’s order certifying a nationwide class of up to 250 million people.  The Ninth Circuit concluded that a common issue of law does not predominate because the laws of other several states apply, not just California’s Cartwright Act and Unfair Competition Law.  In re Qualcomm Antitrust Litig., No. 19-15159, 2021 WL 4448713 (9th Cir. Sept. 29, 2021).  The indirect purchaser plaintiffs are consumers who allege that Qualcomm Incorporated (“Qualcomm”) violated federal antitrust laws and California’s Cartwright Act and Unfair Competition Law by engaging in certain corporate policies regarding their licensing of standard essential patents (“SEPs”) and related sales of modem chips.  The Ninth Circuit held that California’s choice of law rules precluded class certification because states without an Illinois Brick repealer statute, which often authorize indirect purchasers to bring antitrust damages suits, “have a clear interest in applying their laws to class members” and to apply only California law would “allow[] California to set antitrust enforcement policy for the entire country.”

On August 20, 2021, Judge Rebecca Smith of the United States District Court for the Eastern District of Virginia certified a class of end-payor plaintiffs (“EPPs”) alleging that defendant pharmaceutical companies (“defendants”) entered into a reverse payment agreement that delayed generic competition to the branded cholesterol drug Zetia in violation of Section 1 of the Sherman Act.  In re Zetia (Ezetimibe) Antitrust Litig., MDL No. 2:18-md-2836 (E. D. Va. 2021).  This case is part of a multidistrict litigation against defendants, and Judge Smith’s certification decision was in the face of a Fourth Circuit decision two weeks prior that vacated her decision to certify a different class of plaintiffs.

On July 23, 2021, the United States District Court for the Southern District of Illinois denied a named plaintiff’s motion for class certification against Defendants Jimmy John’s Franchise, LLC and Jimmy John’s Enterprises, LLC on the basis that he did not meet the factors required to certify a class—among which included his failure to show that his claims where typical of the claims of the potential class members he purported to represent.  Conrad v. Jimmy John’s Franchise, LLC, No. 18-CV-00133-NJR (S.D. Ill. July 23, 2021).

On April 6, 2021, the United States Court of Appeals for the Ninth Circuit vacated a district court order certifying three classes in a multi-district antitrust case alleging a price-fixing conspiracy by producers of packaged tuna, finding that the district court erred in determining that plaintiffs had satisfied to the predominance requirement of Federal Rule of Civil Procedure 23(b)(3).  Olean Wholesale Grocery Coop v. Bumble Bee Foods, No. 19-56514 (9th Cir. Apr. 6, 2021).  Specifically, the Court concluded that the district court abused its discretion in declining to resolve whether plaintiffs’ proposed use of statistical evidence to establish classwide impact swept a substantial number of uninjured purchasers into the putative class.  A class cannot be certified, the Court held, when it contains more than a “de minimis” number of uninjured purchasers. 

On March 10, 2021, Judge Stephanie Gallagher of the United States District Court for the District of Maryland denied defendants’ motions to dismiss antitrust claims brought by a putative class of poultry workers asserting that poultry processing companies unlawfully exchanged compensation data and conspired to fix and depress employee wages.  Jien v. Perdue Farms, Inc., No. 1:19-CV-2521-SAG (D. Md. March 10, 2021).
 

On December 1, 2020, Judge Raymond A. Jackson of the United States District Court for the Eastern District of Virginia granted plaintiff peanut farmers’ motion for class certification against defendant peanut shelling companies.  D&M Farms, et al. v. Birdsong Corp., et al., No. 2:19-cv-463 (E. D. Va. 2020).  Plaintiffs alleged that defendants conspired to lower the price of peanuts since as early as January 2014 in violation of Sherman Act § 1.  The court certified plaintiffs’ proposed class after finding the facts submitted by plaintiffs and plaintiffs’ expert analysis satisfied the class certification requirements.
 

On August 27, 2020, Judge Jon S. Tigar of the United States District Court for the Northern District of California denied a motion to intervene filed by two subclasses of indirect cathode ray tube purchasers (“Non-Settling Plaintiffs”) that would have allowed them to derail a $500 million settlement between 22 state classes of indirect purchasers (“Settling Plaintiffs”) and seven cathode ray tube manufacturers (“Settling Defendants”).  The Non-Settling Plaintiffs sought intervention in order to appeal the District Court’s final approval of the settlement.  The decision is In re Cathode Ray Tube (CRT) Antitrust Litig., No. 07-cv-05944-JST (N.D. Cal. Aug. 27, 2020).
 

On August 21, 2020, Judge Rebecca Beach Smith of the United States District Court for the Eastern District of Virginia certified a class of thirty-five direct purchasers.  In Re Zetia (Ezetimibe) Antitrust Litigation, 19-cv-00014 (E.D. Va.  Aug. 21, 2020).  Plaintiffs, direct purchasers of the branded drug Zetia, alleged that defendant pharmaceutical manufacturers engaged in an unlawful reverse-payment settlement whereby the manufacturer of the branded drug Zetia agreed to pay a generic manufacturer approximately $800 million to delay its launch of a generic for Zetia for nearly five years.  Zetia is a drug that prevents cholesterol by inhibiting the buildup of plaque in arteries.  The issue before the district court was whether Rule 23 class certification was proper of a direct-purchaser class of only thirty-five members.  In finding it was, the court found it credible that many class members would not find it financially worthwhile to pursue the case on their own and that judicial economy would be best served by certification.
 

On July 23, 2020, U.S. District Judge Paul A. Engelmayer of the United States District Court for the Southern District of New York denied a motion for class certification in the Aluminum Warehousing Antitrust Litigation based on plaintiffs’ failure to show that they could establish class-wide impact through common proof.  The case is significant, among other things, in its close examination and rejection of plaintiffs’ statistical models based on average impact that mask the existence of putative class members who did not suffer any injury.
 

On May 29, 2020, the Court of Appeal for the Fifth Appellate District of California (Judge Brad Hill) reversed the lower court’s denial of certification for a class of convenience store owners pursuing a price discrimination claim under California law.  Dhillon, et al. v. Anheuser-Busch, LLC, et al., No. F074952, 2020 WL 2786837 (Cal. Ct. App. May 29, 2020).  Plaintiffs alleged that defendants, a major brewer and its distributor, violated California law requiring wholesalers to sell to retailers on a nondiscriminatory basis and charge only the prices filed with the Department of Alcoholic Beverage Control.  Specifically, plaintiffs alleged that defendants engaged in a systematic scheme to favor certain retailers over others in the pricing of beer by issuing a disproportionately large number of consumer coupons to favored retailers.  Those retailers, in turn, allegedly redeemed the coupons themselves rather than issuing them to customers to use in connection with a particular beer sale.  Based on this scheme, plaintiffs alleged, the favored retailers effectively received wholesale prices, below the prices paid by “disfavored” retailers.
 

On June 3, 2020, Judge Jan E. DuBois of the United States District Court for the Eastern District of Pennsylvania denied the End-Payor Plaintiffs’ (“EPPs”) motion for class certification in a multidistrict litigation (“MDL”) challenging the settlement practice of pay-for-delay.  In re Niaspan Antitrust Litig., No. 13-MD-2460, 2020 WL 2933824 (E.D. Pa. June 3, 2020).  The district court denied the EPPs’ motion for class certification because the EPPs failed to demonstrate, by a preponderance of the evidence, the requirements of ascertainability, predominance, and superiority.
 

On August 16, 2019, the United States Court of Appeals for the District of Columbia Circuit affirmed a lower court’s decision to deny class certification in an antitrust action involving some of the country’s largest freight railroad companies.  In Re: Rail Freight Fuel Surcharge Antitrust Litigation, MDL No. 1869, (D.C. Cir. Aug. 16, 2019).  Plaintiffs alleged that defendants conspired to fix rate-based fuel surcharges in violation of Section 1 of the Sherman Act, Section 4 of the Clayton Act and various state laws.  The panel, which consisted of Chief Judge Merrick Garland and Judges Judith Rogers and Gregory Katsas, held that class certification was inappropriate because plaintiffs’ regression analysis did not establish predominance.

On July 30, 2019, U.S. District Court Judge Janis Sammartino of the Southern District of California certified three separate classes of tuna purchasers alleging price-fixing by producers of packaged tuna:  (1) direct-purchaser plaintiffs, (2) commercial-food-preparer plaintiffs, and (3) end-payer plaintiffs.  In re Packaged Seafood Products Antitrust Litigation, No. 15-MD-2670, July 30, 2019.

On June 20, 2019, Judge Joy Flowers Conti of the Western District of Pennsylvania dismissed plaintiffs’ class claims that defendant employers colluded to suppress market wages by agreeing not to hire each other’s employees.  The Court found that the complaint failed to adequately plead that all or nearly all employees in the proposed class were harmed by the alleged collusion.  In re Railway Industry Employee No-Poach Antitrust Litigation, No. 18-798 (W.D. Pa. June 20, 2019).  The Court, however, acknowledged plaintiffs had sufficiently pled the existence of an overarching conspiracy among defendants from 2014 to 2016 and individual agreements among each of the three defendants beginning at different times since 2009.  Since the class claims were dismissed without prejudice, plaintiffs have the opportunity to remedy their class-related pleading defects. 

On October 30, 2018, Judge Madeline C. Arleo of the United States District Court for the District of New Jersey declined to certify a proposed consumer class in litigation accusing a pharmaceutical manufacturer (the “Company”) of maintaining a monopoly for two of its drugs. Judge Arleo held that, under Federal Rule of Civil Procedure 23, a class cannot be certified when a non-trivial portion of class members were not injured, absent some “reasonable and workable plan” to segregate those members from the rest of the class. In re Thalomid and Revlimid Antitrust Litig., No. 2:14-cv-06997, at *26, *29 (D.N.J. Oct. 30, 2018) (“Opinion”). In so holding, Judge Arleo relied heavily on the First Circuit’s recent decision in In re Asacol Antitrust Litig., which reversed a district court’s approval of a class on similar grounds. No. 18-1065, 2018 WL 4958856, at *11 (1st Cir. Oct. 15, 2018); https://www.lit-antitrust.shearman.com/first-circuit-reverses-class-certification-based.

On October 15, 2018, the United Stated Court of Appeals for the First Circuit, in an opinion by Judge William J. Kayatta, reversed a district court’s certification of a class of indirect purchasers of the drug Asacol, holding that, under Federal Rule of Civil Procedure 23, a class cannot be certified when a non-trivial portion of class members were not injured in fact, absent some “reasonable and workable plan” to segregate those members from the rest of the class.  In re Asacol Antitrust Litig., No. 18-1065, 2018 WL 4958856, at *11 (1st Cir. Oct. 15, 2018). 

On July 16, 2018, in the latest development in the litigation over the “reverse payment” settlements relating to the pharmaceutical testosterone replacement AndroGel that the Supreme Court addressed in FTC v. Actavis, Inc., 570 U.S. 136 (2013), Judge Thomas W. Thrash, Jr. of the United States District Court for the Northern District of Georgia denied class certification to a proposed class of direct purchaser plaintiffs. In re AndroGel Antitrust Litigation (No. II), No. 2084, 2018 WL 3424612 (N.D. Ga. July 15, 2018). 

On March 5, 2018, Judge Yvonne Gonzalez Rogers of the U.S. District Court for the Northern District of California denied class certification for a group of indirect purchasers alleging price fixing in the sale of lithium batteries, holding that the plaintiffs failed to demonstrate that they had a reliable method of proving pass-through of the alleged overcharges on a class-wide basis.  In so holding, the Court relied primarily on the plaintiffs’ expert’s failure to account for the effects of “focal point pricing,” the practice of pricing consumer products at certain attractive retail price points, for example, $799 or $1299.

On February 28, 2018, Judge Naomi Reice Buchwald of the Southern District of New York denied class certification to two proposed classes in the LIBOR rate manipulation litigation, while granting partial certification to a third class.  In re LIBOR-Based Fin. Instruments Antitrust Litig., No 1:11-cv-02613-NRB (S.D.N.Y. Feb. 28, 2018).  At issue in this thorough 366-page decision were three proposed classes:  (1) the “exchange-based” class, (2) the “lender” class, and (3) the “over-the-counter” or “OTC” class, all seeking to recover damages based on alleged manipulation of the London Inter-bank Offered Rate (“LIBOR”).

On October 16, 2017, Judge Denise J. Casper of the United States District Court for the District of Massachusetts granted class certification to two classes of purchasers allegedly injured by a pay-for-delay scheme relating to prescription drug Solodyn:  a Direct Purchaser Plaintiff class (“DPPs”) and an End-Payor Plaintiff class (“EPPs”).  In Re Solodyn (Minocycline Hydrochloride) Antitrust Litig., No. 14-md-02503 (D. Mass. Oct. 16, 2017).  In certifying the DPP class, the Court rejected the argument that affiliated corporate entities should be consolidated in evaluating the numerosity requirement of Federal Rule of Civil Procedure 23(a).  In certifying both classes, the Court accepted the plaintiffs’ experts’ proffered methodologies to establish common or class-wide impact as adequate for Rule 23 purposes over a variety of defense challenges.
