Mason LPP's investigation of ESPN has revealed that it is using the Meta Pixel on its website in violation of the federal Video Privacy Protection Act.  ESPN is violating federal and state privacy laws by using a tracking tool, known as the Meta Pixel,  to secretly gather data about ESPN subscribers – specifically, their unique Facebook IDs and details about the videos they’ve watched on the ESPN website – and pass along the data to Meta (formerly known as Facebook)  without informed written consent.

This matter arises from an unlawful antitrust price-fixing cartel directed at the U.S. market for multi-family property rentals involving RealPage, Inc. (“RealPage”), a real estate data analytics and rent price setting company, and its subscribers which include the largest multi-family residential lessors/property managers in the United States.  Beginning no later than 2016, RealPage facilitated a price-fixing cartel among its subscribers whereby RealPage fixed the lease prices and managed the output of its subscribers’ multifamily rental units on a day-to-day basis through the use of RealPage’s proprietary revenue management software currently referred to as “AI Revenue Management” (formerly referred to as “YieldStar”) resulting in unlawfully inflated lease prices paid by the lessors of apartments on multifamily residential buildings.   

Mason LLP represents hundreds of gamers with claims against  Valve, the owner of Steam.  These claims must be pursued in arbitration pursuant to the Steam Terms of Service.  The arbitration claims are related to a federal class action filed by Wolfire Games, a game publisher, claiming that Valve uses its monopoly power to force game publishers to sell their games through the Steam Store and to pay Valve supra-competitive commissions. This same conduct causes gamers to pay more for games as well. Game consumers tried to bring a class action, but the court ruled that these claims can only be pursued through individual arbitrations.

 Ozone is a toxic gas that can kill bacteria and viruses, but there is a cost. If the concentration of the ozone is strong enough to kill bacteria and viruses, it is also unsafe for people and animals. Companies that manufacture devices that emit ozone are required to disclose that information. The SoClean CPAP sanitizer machines work in sterilizing machines, but the manufacturer has failed to disclose that its products emit ozone, according to a SoClean lawsuit. In fact, SoClean has claimed the devices are “safe” and “healthy”, the lawsuit claims. SoClean CPAP sanitizer owners may be able to join a class action lawsuit against the company for falsely advertising the safety of their products.
