JSD SUPPLY INC.

JSD Supply is a private company founded in 2013 and headquartered in Prospect, Pennsylvania. The company's legal name is Not An LLC, and it does business as JSD Supply. It was founded by its owner, Jordan Vinroe, initially as a sole proprietorship before incorporating as an LLC. While specific revenue and employee figures are not publicly available, court filings indicate it has multiple staff members.

JSD Supply is an e-commerce retailer specializing in parts and kits for firearms. Its primary products include aftermarket components for popular handgun and rifle platforms, such as Glocks and AR-15s. The company is a prominent seller of "80% receivers" or "lower" frames and build kits, which allow customers to assemble firearms that are unserialized and untraceable, often referred to as "ghost guns." In addition to frames, the company sells compatible slides, barrels, trigger assemblies, and tools required for assembly.

The company's patent litigation posture, based on available data, is that of an operating company defending its business. It has been named as a defendant in one tracked patent case and has not been recorded as a plaintiff. This pattern is typical of a company focused on producing and selling goods rather than patent monetization. The single case was filed in the Illinois Northern District Court.

JSD Supply is more notable for its involvement in high-profile public interest and regulatory lawsuits than for patent disputes. The company has been sued by the City of Philadelphia and gun control advocacy groups seeking to halt the sale of its "ghost gun" kits. In April 2024, JSD Supply settled a lawsuit with Philadelphia, agreeing to temporarily stop selling its products in the city. The company has also been a party in litigation against the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) concerning federal regulations of firearm parts.
