HP, via its China HP company (HP), has sued Zhuhai based  Zhuhai Sharing Color Printing Consumables Co. Ltd alleging infringement of two HP patents.

The two complaints were filed in the Shanghai IP court in March 2019  alleging that the Sharing Color new 803 integrated inkjet cartridges breach HP’s IP in respect of printhead multiplexing and addressing circuitry.

The HP 803 integrated inkjet cartridge is a mainstay of HP’s current generation print cartridges and is found in a wide range of inkjet printers.

New HP cartridges were updated in 2017 and are only compatible with current and future printers and do not work with older printers. In August 2018 The Recycler reported concerns about this action. It is not known at this time if the alleged Sharing Color products work with the current generation of printers.

HP has been aggressive and successful in defending its inkjet IP and legal actions taken in recent years have upheld these crucial patents in China.
