Cartridge Hut and Paperwork Plus — identified in the ITC record only as "Cartridge Hut and Paperwork Plus of Sun City, California" — was a small U.S. dealer in aftermarket (non-OEM) inkjet printer cartridges. No founding year, employee count, revenue figure, or current operating status could be verified from public sources; it does not appear in current company registries or press coverage, and no parent, subsidiary, or ownership relationship is documented. Treat any size or ownership characterization as unverified.
Products / services. The company's only documented activity is the importation and resale of replacement inkjet print cartridges manufactured by Microjet Technology Co., Ltd. of Taipei, Taiwan. Public ITC and HP documents describe its offerings by what they replaced — notably cartridges intended as substitutes for the HP 51626A and HP 51629A models. Nothing in the record indicates that it manufactured, refilled, or developed cartridge technology itself; it was a distributor/retailer in the third-party supplies channel.
Litigation posture. The case data is unambiguous: zero plaintiff cases and one defendant case, all in the U.S. International Trade Commission. That profile is the signature of a small operating reseller that was targeted, not of a patent assertion entity. Cartridge Hut never asserted patents; it was a respondent in an OEM-initiated enforcement action.
Notable case. Hewlett-Packard Company v. Microjet Technology Co., Ltd. et al., ITC Investigation No. 337-TA-459, "Certain Ink Jet Print Cartridges and Components Thereof," was instituted January 19, 2001 on a complaint filed December 22, 2000. HP alleged a Section 337 violation based on infringement of six patents (U.S. 4,827,294; 4,635,073; 4,680,859; 4,872,027; 4,992,802; and 5,409,134) through the importation and sale of Microjet-manufactured cartridges. Co-respondents included Microjet Technology, Printer Essentials (Reno, NV), Price-Less Inkjet Cartridge Company and ABCCo.net (Port Charlotte, FL). The investigation was terminated as to Cartridge Hut by consent order (Order No. 15, October 12, 2001) after the company acknowledged the cartridges were covered by HP's patents and agreed to stop importing and selling them. The ALJ's January 2002 final determination found a violation as to the remaining parties; Cartridge Hut was no longer a participant by then.
