As an avid runner, I am always looking for the perfect protein bar. A great protein bar must find the balance between taste and texture on the one hand and nutritional value and low-caloric content on the other. Usually, a certain amount of fat is needed for a savory taste and smooth texture, but that also often increases the bar’s calorie count.
So, it was interesting to discover an antitrust case involving this particular dilemma. The case was Own Your Hunger LLC, Lighten Up Foods, and Defiant Foods LLC vs. Linus Technology, Inc., Epogee LLC, and Peter Rahal. The lawsuit was filed in the United States District Court for the Southern District of New York in June 2025 by three low-calorie food producers that use esterified propoxylated glycerol (“EPG”), a patented fat replacement vegetable-based ingredient that that reduces calories by 92% compared to an equal amount of ordinary animal fat ingredients. EPG is produced only by a company named Epogee, because it holds the exclusive patent for EPG. The three food-producer plaintiffs make and distribute nut butter spreads, sauces and chocolates, respectively.
The defendant is Linus Technology operating under the name David Protein, which produces and distributes protein bars, marketed under the name David Bars, which also contain EPG. On May 29, 2025, David Protein acquired Epogee. After being acquired, Epogee (now part of David Protein) notified the three plaintiffs that it would no longer accept new orders for EPG.
The plaintiffs sued under the Sherman Act, Clayton Act and New York State’s antitrust statute, The Donnelly Act, and sought a temporary restraining order and a preliminary injunction. They claimed the defendants violated those statutes by arranging for the acquisition of Epogee and using their control over EPG to create an artificial monopoly. Specifically, they claimed that Epogee maintained a reliable EPG supply for all qualified food manufacturers before the corporate transition, and that after David Protein acquired it, Epogee advised the plaintiffs that it would no longer fulfill new orders for EPG. Moreover, plaintiffs alleged that Epogee stockpiled EPG to ensure that plaintiffs had no access to EPG. Defendants argued that plaintiffs are solely responsible for their predicament because they failed to secure long-term supply contracts, unlike other Epogee customers who still receive supply.
Plaintiffs asked for a temporary restraining order and a preliminary injunction to stop the defendants from, among other things, limiting EPG access to its pre-existing customers, maintaining artificial supply shortages, creating artificial scarcity of EPG through inventory manipulation and concealing information about EPG availability.
The applicable antitrust statutes typically require the plaintiffs to define the relevant product and geographic markets in which the products compete, along with the alleged restraint of trade.
Courts generally define the relevant market as all products reasonably interchangeable by consumers for the same purposes. Interchangeability is the cross-elasticity of demand between the product itself and substitutes for it. Two products are reasonably interchangeable where there is cross-elasticity of demand – where consumers would respond to a slight increase in in the price of one product by substituting for the other.
