PVC Pipe Antitrust Litigation
Overview
Lockridge Grindal Nauen (“LGN”) is Co-Lead Counsel for a class of consumers, plumbers, electricians, and other contractors who bought PVC Pipe or PVC Fittings (collectively called PVC Pipe Systems) from a distributor or home improvement store. LGN’s complaint alleges that PVC Pipes and Fittings were price-fixed because the companies that make PVC Pipes (called Converters) conspired with an industry reporting service called OPIS to increase their price starting at least as early as 2020 through the present.
The lawsuit alleges: “PVC Pipe System prices exploded in 2020. The nation’s leading PVC Pipe System manufacturers—the Converter Defendants—blamed the price explosion on COVID-19 and supply chain chaos. They were lying. The astronomical price increases resulted from an elaborate price-fixing Conspiracy, not pandemic disruptions. Working hand-in-glove with industry reporting service, Defendant OPIS, Converter Defendants weaponized temporary shocks to the supply of PVC resin—the primary raw material in PVC Pipe Systems—as cover to orchestrate a brazen price-fixing scheme. The results were staggering: PVC Pipe System prices quadrupled, generating windfall profits while devasting pipe purchasers nationwide.”
The lawsuit further alleges that “OPIS not only facilitated, but it also directly participated in,the fixing of PVC Pipe System prices. Until recently, casual observers might have viewed OPIS as simply providing information exchange of data and signaling between competitors. However, OPIS has produced thousands of pages of handwritten notes, over 8,000 text messages, and thousands of emails from its employee Donna Todd. These documents reveal classic antitrust violations: direct evidence of communications among Converter Defendants’—ostensibly competitors—to agree on and fix PVC Pipe System prices.”
Additionally, the lawsuit alleges that the largest distributors of the PVC Pipe Systems in the United States conspired with Defendants to implement the alleged Conspiracy. The Co-Conspirator Distributors—Core & Main, Ferguson, Fortiline, Hajoca, Porter Pipe, and United Pipe—shared a powerful economic interest with the Converter Defendants in artificially inflating PVC Pipe Systems prices: enhanced profits and financial stability.
What are PVC Pipe Systems?
PVC Pipe Systems consist of two necessary and complementary components: (1) PVC Pipes and (2) PVC Fittings that connect PVC Pipe segments into piping systems. The PVC Pipe Systems industry centers on three major applications: (1) Municipal Pipe, for drinking water and sewer systems (blue and green pipes), (2) Plumbing Pipe, for residential and commercial drain, waste, or vent (“DWV”) pipe systems (typically white pipes), and (3) Conduit Pipe, for protecting electrical wires (usually gray pipes). Common PVC Fittings include couplings and unions, elbows, tees, crosses, caps and plugs, adapters and bushings, nipples, and flanges.
Details on Parties and the Complaint
The Class that LGN represents is called the NCSP Class, which stands for Non-Converter Seller Purchasers. In other words, NCSP Class members are those who bought PVC Pipes or Fittings from a distributor or home improvement store, with some minor exceptions, such as consumers, plumbers, electricians, and other contractors.
The Defendants are OPIS, Atkore, Cantex, Charlotte Pipe, Cresline, Diamond Plastics IPEX/Multi Fittings, JM Eagle, National Pipe, Northern Pipe, Otter Tail, Prime Conduit, Sanderson Pipe, Southern Pipe, Westlake (NAPCO), and Vinyltech.
Settlements
The NCSP Class reached a settlement with Defendant OPIS on May 16, 2025. The Court granted Preliminary Approval to this settlement on July 15, 2025. NCSP Co-Lead Counsel are implementing the Court-ordered plan of notice to inform NCSP Class members of the settlement.

Allianz Life Investigation
Background
Allianz Life is a global life insurance provider offering policies for individuals across the country. The company holds the data of millions of individuals as part of its business.
What Happened
On July 25, 2025, Allianz Life notified government offices that its system was breached by threat actors on July 16, 2025. They reported their third-party cloud-based customer information system was breached by hackers, who took information on more than 1.4 million customers of Allianz Life. The breached data includes Social Security numbers, policy and contract numbers, dates of birth, mailing addresses, phone numbers, and email addresses.

Lemonade, Inc. Investigation
Insurer Lemonade, Inc. (“Lemonade”) is the subject of a new series of lawsuits over its convenience-focused online quoting tool that disclosed drivers’ license numbers to unauthorized third parties.
Background
Lemonade, the newest major insurance company, included a tool on its public website that was designed to make it easier for individuals to obtain quotes for insurance policies by auto-populating certain information on behalf of the individual. When the individual entered only basic information, Lemonade’s website would automatically run a search for additional data obtained from other sources, and populate that information on Lemonade’s website to complete the quote. This tool was designed to make it easier for applicants to complete quotes and buy policies without having to dig out their driver’s license card or other documents.
What Happened
Cybercriminals identified Lemonade’s website as a way to obtain the drivers’ license numbers for many individuals in order to engage in various crimes. By entering a victim’s basic information, which might be publicly available online (e.g. on social media), Lemonade would disclose the person’s driver’s license number. Approximately 190,000 drivers’ license numbers were exposed to these third parties over a period of 17 months without any concrete action by Lemonade to identify or stop the threat. It is still unclear if the company has fixed the vulnerability.
Users Face New Harms
Victims whose drivers’ license numbers were obtained through Lemonade’s website face many kinds of threats. Because our drivers’ license numbers are so confidential and personal, criminals are able to use them to commit more severe forms of fraud. With access to these drivers’ license numbers, criminals can solicit loans, access retirement accounts, charge to the victims’ credit cards, and more. Without the drivers’ license numbers, criminals would have far less access to the victims’ virtual and financial lives. Besides the obvious fraud that can result from this disclosure, victims also face a heightened risk of future fraud as well as the loss of value in that information, lost time spent trying to stop existing fraud, and lost time preventing future injuries. Victims may spend years, even their entire lives, spending extra time and money monitoring their credit and other financial accounts.
Victims may be able to seek damages from Lemonade including compensation for actual losses, statutory damages, and injunctive relief. If you believe your information has been disclosed by Lemonade and experienced any of the injuries described above, submit the form below to learn more about what you can do.

Tea Dating Advice Investigation
Background
Tea Dating Advice (“Tea Dating”) is an app created in 2023 to serve women using dating apps. Tea sought to give women the ability to vet the men they find on dating apps. Women are able to post feedback and information about men across different dating apps and subsequent women may review that feedback for red flags. The Tea Dating app is only for women, and men are not allowed to join. To enforce this rule, the app verifies whether the people signing up for Tea Dating are women. For a time, Tea Dating required users to upload a photo of the user’s driver’s license, though it later only required photos.
What Happened
Recently, actors posting on the site 4chan announced they had discovered a database related to the Tea Dating app including photos of users’ driver’s licenses and other information. This information was quickly spread on the internet. Tea Dating has confirmed this incident. The database was hosted on Google’s Firebase platform owned by Tea Dating. The company claims to have more than 1.6 million users, and some reports show tens of thousands of users’ data were exposed. Given how the data was stored, Tea Dating failed to utilize reasonable security measures to ensure its users’ personal data was safe. Tea Dating asked for and received users’ personal information, including drivers license numbers, as a condition to using Tea Dating’s platform.
Users Face New Harms
The users who have had data exposed from the Tea Dating disclosure face a heightened risk of fraud and identify theft, but also a very real risk of retaliation. Tea knew, or should have known, that the men identified on its platform would seek both the content posted on the app as well as the identities of the women posting that content. This may increase the users’ risk of retaliation, dating violence, and fraud.
Victims of this disclosure face many kinds of injuries including but not limited to identity theft, spam, credit fraud, loss of control of their information, and lost time spent trying to get the information removed from publicly accessible places.
If you registered for the Tea Dating Advice app anytime since 2023, your information may have been made public as a result of Tea Dating’s failures to safeguard your data. Please fill out the form below immediately to learn more about your rights.

Construction Equipment Rental Antitrust Litigation
Background
The U.S. market for construction equipment rental is substantial and growing. Individuals and companies often rent rather than purchase the equipment they need for construction projects because renting is usually more affordable, especially for smaller companies or for short-term projects. Renting also allows companies to access newer, more up-to-date equipment models.
Beginning in at least 2021, the largest construction equipment rental companies substantially raised rental prices and have kept them at an elevated level since. The lawsuit alleges that these rental equipment companies coordinated with Rouse Services LLC, and Rouse’s parent, RB Global, to restrain competition and share competitively sensitive information in violation of Section 1 of the Sherman Act. The Defendants agreed to exchange competitively sensitive, non-public data, such as rental invoices and real-time inventory data, to coordinate their pricing through Rouse in order to maximize rental rates. Rouse launched its Rental Insights (“RRI”) product in 2011. Since then, the number of companies using its system has increased to approximately 400, including all major industry players and at least 60% of the North American rental equipment market.
The lawsuit alleges that not only does Rouse collect competitively sensitive information from all its clients – which it uses to set prices across rental companies – it also explicitly tells rental companies who else is sharing their data and which pricing strategies they are employing. One rental equipment defendant executive admitted: “We’re all using the same data.” Another explained that Rouse “essentially standardized a lot of price competition in the industry.”
The lawsuit alleges that the construction equipment rental industry is particularly susceptible to antitrust conspiracies due to increasing consolidation within the industry. As the dominant players holding the majority of market share for construction equipment rentals, the rental equipment company defendants dictate the prices offered to individuals and companies who rent construction equipment.
The lawsuit was filed in the United States District Court for the Northern District of Illinois on April 17, 2025, and is captioned Kris Swanson Construction LLC v. RB Global, Inc.; et al., Case No. 1:25-cv-04236.

SaveOnSP and PrudentRx
Overview
Pharmacy Benefit Managers (“PBMs”) like Express Scripts and Caremark have partnered with secretive third party companies, such as SaveOnSP and PrudentRx, to siphon off patient copay assistance meant to help patients afford their prescription drugs and to foist thousands of dollars of additional healthcare costs onto patients. Lockridge Grindal Nauen PLLP (“LGN”) has filed suit against these programs for violating federal fraud and insurance laws, and for increasing healthcare costs for targeted patients.
Background
The Affordable Care Act (the “ACA”) provides safeguards against excess healthcare costs for patients in the U.S., including an upper limit on patients’ copay and coinsurance obligations and a maximum that a patient can be forced to pay out-of-pocket each year. Still, prescription drug costs threaten to undermine these protections. PBMs negotiate steep discounts off of drugs’ list prices for the benefit of health plans, but refuse to share those discounts with patients. The result is disproportionately high costs for patients whose need life-saving, but expensive, medications.
Studies lay bare the disastrous effects of PBMs’ efforts to shift healthcare costs to patients: a majority of patients on employer-sponsored health plans report delaying filling prescriptions, rationing medications, or skipping prescribed therapy altogether due to cost. Three quarters of patients cannot afford prescriptions that cost $250 or more out of pocket. To help ensure patients can access necessary and life-saving medications, manufacturers of drugs with high patient costs offer patient assistance programs. These programs cover patients’ out-of-pocket costs up to a set amount. These patient assistance programs, traditionally, have helped reduce the cost burdens of patients with complex and expensive medical conditions.
Recently, PBMs have partnered with companies like SaveOnSP and PrudentRx to evade the ACA’s protections and nullify the relief that patient assistance programs provide. These companies claim to have found a loophole in the ACA: they target expensive medications with the most generous patient assistance programs and designate those drugs “non-essential health benefits,” regardless of how essential the medications may be to a patient’s health. This, they claim, allows health plans to charge copays and coinsurance in excess of the ACA’s limits, and to refuse to count those payments—by patients or patient assistance programs—towards patients’ out-of-pocket limits.
Once retained by a health plan, SaveOnSP and PrudentRx target patients who are on these drugs and increase their out-of-pocket obligations to hundreds, if not thousands of dollars a
month. They then coerce patients to agree to participate in their programs with misleading promises of $0 copays if they participate and the threat of thousands of dollars in out-of-pocket costs if they do not. When patients sign up, these patient assistance raiders drain the maximum amount of funding available from patient assistance programs, and then give that assistance to insurers, not patients.
Targeted patients, meanwhile, lose the benefit of patient assistance. SaveOnSP and PrudentRX refuse to count the large patient assistance payments they collect towards patient’s out-of-pocket obligations. As a result, targeted patients end up having to pay thousands of dollars in additional medical costs during the year that otherwise would have been paid by their insurer after they reached their maximum out-of-pocket limits.
Details of the Cases
LGN has filed two lawsuits against healthcare industry companies, alleging that those companies steal patient copay assistance funds, violate the ACA, and force patients to incur excess healthcare costs.
Gluesing v. PrudentRx LLC, et al. (filed in federal court in Rhode Island) seeks to hold PrudentRx, LLC and Caremark Rx LLC accountable for a fraudulent scheme to force patients to pay thousands more for their health insurance by depriving patients of the benefit of patient copay assistance. On February 6, 2025, the court appointed LGN to serve as interim lead class counsel in this important litigation.
Gurwitch v. Save On SP, LLC, et al. (filed in federal Court in the Northern District of New York) seeks to hold Save On SP LLC; Express Scripts, Inc.; and Accredo Health Services, Inc. accountable for a similar scheme.

GoodRx Antitrust Litigation
Overview
Lockridge Grindal Nauen PLLP has filed an antitrust class action lawsuit against generic drug coupon provider GoodRx and Pharmacy Benefit Managers (PBMs) Caremark, Express Scripts, MedImpact, and Navitus. The lawsuit challenges those defendants’ conduct in artificially suppressing prescription drug reimbursement rates paid to independent pharmacies, and increasing fees charged to independent pharmacies, through the use of GoodRx-supplied prices. The defendants’ conduct has caused financial harm to independent pharmacies throughout the country.
What Does the Lawsuit Allege?
The lawsuit alleges that GoodRx and the PBM defendants conspired to suppress reimbursement rates and increase fees charged to independent pharmacies on all GoodRx-related transactions through GoodRx’s “integrated savings program.” The GoodRx integrated savings program uses GoodRx’s pricing algorithm, and real-time pricing information from PBMs, to determine prices of generic drug transactions—and to enrich GoodRx and the PBMs at the expense of independent pharmacies.
The lawsuit seeks to recover the damages incurred by independent pharmacies throughout the United States, and to put a stop to the illegal conduct of GoodRx and the PBMs in participating in the GoodRx integrated savings program. It is the first lawsuit in the U.S. challenging this conduct.
Who is Affected?
Independent pharmacies throughout the United States may have been affected by the defendants’ conduct. If your pharmacy has dispensed generic prescription medication to a patient using insurance and received reimbursement from Caremark, Express Scripts, MedImpact, or Navitus for that prescription at a GoodRx-supplied price, it may have been injured by the defendants’ conduct.
Details on the Parties and the Complaint
The plaintiff, Keaveny Drug, an independent pharmacy in Minnesota, filed the lawsuit in the U.S. District Court for the Central District of California. The lawsuit is captioned Keaveny Drug, Inc. v. GoodRx, Inc. et al. Case No. 2:24-cv-09379. The defendants are GoodRx, Inc., GoodRx Holdings, Inc., CVS Caremark Corp., Express Scripts, Inc., MedImpact Healthcare Systems, Inc., and Navitus Health Solutions, LLC.

Admixtures Antitrust Litigation
Summary
Lockridge Grindal Nauen is prosecuting an antitrust class action alleging that the world’s largest manufacturers of concrete and cement additives conspired with each other to increase the prices they charge for those construction chemicals.
Background
The defendants and potential defendants accused of conspiring to fix the prices of their admixtures are:
The complaint alleges that the defendants implemented their agreement to raise the prices of their concrete and cement additives through constant price increases and surcharges, resulting in skyrocketing prices for concrete and cement additives sold in the United States. This antitrust class action comes on the heels of dawn raids by the European Commission and the United Kingdom’s Competition and Markets Authority, and grand jury proceedings by the United States Department of Justice, because of potential violations of antitrust laws that prohibit cartels and restrictive business practices.
Were you affected by the alleged concrete and cement additives conspiracy?
If your construction company purchased ready-mix concrete, concrete admixtures, cement additives, or admixtures for mortar any time since 2018, you may have overpaid for those construction chemicals.
