    Pelikan recognizes HP’s printer cartridge patent claims
    the context of the patent infringement lawsuit filed by the printer
    manufacturer Hewlett-Packard with the District Court in Düsseldorf
    against the Hanover-based printer consumables supplier Pelikan
    Hardcopy, the defendant has now recognized the patent claims of the
    plaintiff. When asked about the case by heise online, a spokesman of
    the court on the afternoon of Friday the 27th of July 2007 confirmed
    that this was the case. The hearing scheduled for next Thursday had
    therefore been canceled, the spokesman added.

    The lawsuit had
    centered on Pelikan’s alternative cartridges to HP’s No. 28 and No. 57
    triple color cartridges, which are used in many older, still very
    popular Deskjet printers. In a departure from common practice Pelikan
    is alleged to have marketed newly manufactured copies of the originals
    in place of used and refilled original cartridges. The integrated print
    head of these cartridges in particular is protected by a variety of
    patents. Thus HP has patented, among other features, the way in which
    the FET circuits have been adapted and the ground lead arrangement of
    the wiring heater element of the thermal print head. In addition
    Hewlett-Packard had claimed that three of its patents relating to the
    composition of the ink itself had been violated.

    Details of the
    out-of-court settlement have not been released by either party. Neither
    HP nor Pelikan have yet been prepared to comment. It thus remains
    unclear what the impact on the future range of HP inkjet printer
    consumables offered by Pelikan will be. Whether the settlement includes
    a promise by HP to withdraw the action it has filed with the District
    Court in Cologne also remains to be seen. In the action filed there the
    printer manufacturer had accused Pelikan of unfair competition
    practices, because the cartridge copies marketed by Pelikan had on
    their packaging inaccurately been described as recycled products.

    do not exclude the possibility that Pelikan itself might have been the
    victim of irregularities perpetrated by foreign suppliers, which,
    without the headquarters in Hanover being aware of what was happening,
    had on occasion made up for the odd scarcity of empty originals by
    turning to patent-infringing copies made in Asia.
