On December 1, 2025, the UPC delivered a significant win for HP: a preliminary injunction blocking certain third‑party ink‑jet cartridges from being sold in multiple European countries. Law360+2Lewis Silkin+2 The case — filed by HP’s subsidiary Hewlett‑Packard Development Company, L.P. — targeted cartridges manufactured by Shenzhen Moan Technology Co., Ltd. (based in China) and sold by German reseller Andreas Rentmeister e.K. (operating through the online store Toneroffice.de).
The contested cartridges are “rebuilds” compatible with HP’s 937/937XL/937e models. The UPC’s Local Division in Düsseldorf concluded on a preliminary basis that the cartridges likely infringe HP’s European patents — and that those patents are not likely to be invalid. On that basis, the court granted a cross‑border injunction to halt sales, imports, offers and marketing of the infringing cartridges across multiple UPC member states. hoyngrokhmonegier.com+1
According to the court, the injunction was warranted because continuing sales would cause “serious and unjustified harm” to HP’s market position — including lost turnover, market share, and potential reputational damage if lower‑quality cartridges gave customers a bad experience.
