Beat and Dagrinch, gotta register a vote for dag's option "C" and offer an alternative opinion. Let's look at the statement again, and focus our attention on exactly what did not change in a "material" way:
"The Company believes these rulings, which remain under Court seal, do not materially affect the relief sought by InterDigital Technology Corporation."
See that? InterDigital is on record with a definition of "the relief they are seeking", right? It gets stated as x% of infrastructure and y% of subscriber units for 2G standards instead of a lump sum figure in total dollars, but IMO THAT is the "relief sought by InterDigital technology Corporation" referred to in that statement. And it was THAT RELIEF(i.e., the total infringement damages expected from Ericsson) which was "not materially affected by the rulings on PSJ's last year.
OK, (if that makes any sense??), then it seems like PSJ rulings CONFIRMING the validity and infringement of claims WOULD NOT change the relief sought, while rulings which were favorable to Ericsson absolutely WOULD HAVE a "material" affect on the relief sought. One thing for certain is that whoever crafted that press release was leaving plenty of room for interpretation.
