Defendant
1 case as defendant.
The Grease Box LLC is a private company formed in early 2020 and based in Arizona. The company was founded to create a solution to problems with standard grease pails on wood pellet grills. While specific employee or revenue figures are not publicly available, the company partners with other local Arizona businesses for custom components and sells its products through its website and various hardware and BBQ supply retailers.
The company's main product is "The Grease Box," a patented replacement for the open, hanging grease buckets commonly found on wood pellet grills. Made of steel, the product is an enclosed, lockable container designed to be a sturdier and safer way to collect grease runoff. The design aims to prevent spills, protect the collected grease from the elements, and keep children and animals away from the hot grease. The company also offers accessories, such as custom-fit silicone liners for easier cleaning.
As a defendant in one tracked patent case and a plaintiff in none, The Grease Box LLC fits the profile of an operating company defending its products in litigation. The single case against it was filed in its home state's jurisdiction, the Arizona District Court. This posture is typical for a manufacturing company being targeted by an external patent holder.
The company's only tracked litigation is Shenzhen Huajing International Trade Co Ltd v. The Grease Box LLC, filed on April 19, 2026. This case appears to be a refiling of a lawsuit originally brought by Shenzhen Huajing, a Chinese trading company, in the Western District of Washington in July 2025. A federal judge dismissed that earlier case in February 2026 for improper venue, allowing the plaintiff to bring the patent infringement suit again in a more appropriate court.
The accused products are grease containment systems.
