What the complaint alleges
The complaint says Fourstar is a Taiwan corporation with a major office in Clearwater, Florida. It says Quest USA, Corp. and Quest Basics LLC are New York corporations with principal places of business in Brooklyn, New York. It says the Quest Basics website states that Quest Basics is a subsidiary of Quest USA.
The complaint alleges that Fourstar specializes in the creation, development, and sourcing of products, including personal care products, for sale in retail mass merchandisers, including Dollar Tree. It alleges that Fourstar designed the b.pure mark and in 2018 began using it in interstate commerce on personal care products. It alleges that since Fourstar originated the brand in 2018, literally hundreds of millions of units of personal care products marked with b.pure have been sold in the United States. It alleges that the United States Patent and Trademark Office granted five registrations for b.pure: Registration Nos. 5,783,780, 5,915,251, 6,727,031, 6,750,360, and 7,875,504. It alleges that Registration Nos. 5,783,780 and 5,915,251 are incontestable. It alleges that Fourstar presents b.pure in all lowercase letters, with a period between the b and the p.
The complaint alleges that Quest marks and promotes personal care products with "biopure.", presented in all lowercase letters with a period after the e, in a font the complaint calls nearly identical to b.pure. It alleges that Quest first used "BioPure" with capital letters B and P and a leaf logo, and then changed that use to "biopure.", which the complaint says more closely resembles b.pure. It alleges that the Quest mark is visually and aurally confusingly similar. On information and belief, it alleges that Quest chose the lowercase letters and the trailing period to mimic b.pure.
It alleges that Quest USA distributes those products for sale in retail stores, including Dollar Tree and Target, and that the products are displayed in Dollar Tree stores near Fourstar's b.pure products. It alleges that Quest products were purchased from a Dollar Tree store in Pinellas Park, Florida, on August 12, 2026, and from a Target store in Trinity, Florida, on August 13, 2026. It alleges that Quest Basics advertises "biopure." personal care products on the Quest Basics website. It alleges that Quest arranged for "biopure." products to appear as sponsored products on Amazon when a consumer searches for b.pure. It alleges that Fourstar has not authorized that use. Based on information on the United States Patent and Trademark Office website, it alleges that Quest has no federal registration and no pending application for "biopure.", and that Quest products nonetheless state that BIOPURE is a registered trademark of Quest USA Corp.
The prayers in both counts seek an injunction, Fourstar's damages, Quest's profits, treble damages, fees, and an order removing from retail sale and destroying products bearing the "biopure." mark. Those are requests for relief. A court has not granted them.
A complaint is not a ruling
None of this is a finding. A newly filed complaint tells you what Fourstar alleges about b.pure and "biopure." It does not tell you that the defendants infringed or competed unfairly. The court has not decided the case.
