HP has filed a lawsuit against Germany-based Pelikan Hardcopy Deutschland for patent infringement of HP printer cartridges.

The lawsuit claims three patents involving ink cartridge design and three regarding ink formulation have been trodden on. The complaint was filed in Düsseldorf District Court.

The cartridges are sold in Germany under the Pelikan brand and designated as H06 and H08 color cartridges. HP PR manager Sarah Stevens said that even though the cartridges are labeled as remanufactured, "they appear new to us."

Pelikan could not be reached for comment at the time of publication — they don't answer their phones at two in the morning. How rude. ®
