UII is extremely pleased with the judge’s order.
The judge ruled that the Arwen chips do not infringe Lexmark’s patents and are completely out of the case. We knew this all along, but it is nice for the judge to officially confirm that these chips are free of any infringement. For clarification, Arwen chips are the MS/MX and CS/CX families of chips.
We are also pleased that the judge ruled that the Pensive chips (E260, T650, and C540 families) do not literally infringe Lexmark’s punch bit patents.
This means the only issues left in the case are some minor issues regarding the Pensive chips, which we also do not infringe, but the judge wasn’t able to make this ruling in summary judgement. A jury will have to make this ruling in trial.
At this point the important detail for the aftermarket industry is that the MS/MX chips do not infringe any of Lexmark’s patents and are completely out of the case and the only issues remaining are regarding the E260, T650, and C540 chips, which everyone in the industry knows are no longer in high demand.
UII prides itself on developing its own non-infringing technology, where other chip manufacturers from Asia simply copy the OEM technology.
