HP Applies for InkJet Foam Patent

HP Foam
The OEM is attempting to patent the process whereby the foam acts as an airway in the cartridge in Europe, which could be significant for inkjet cartridge remanufacturers.

HP’s patent application, EP 2 807 032 A1, refers to an inkjet cartridge featuring a capillary material – the block of foam – which is placed in the chamber of the cartridge between a vent and outlet, in order for the material – when the ink level has gone down – to then form an airway between the vent and outlet.

In turn, a wick covering an outlet is provided, or the outlet is otherwise configured to create a break in a liquid connection when the air enters the outlet through the material. This application could be significant for inkjet remanufacturers as the replacement of either the material (the foam) or the wick could be considered an infringing act of the patent, should it be granted by the European Patent Office.
