Loop recalls seeing it in an SEC filing, (Could be the 20F).
But I must admit, your reference:
"After failed attempts at negotiating a settlement, Nokia filed an arbitration demand"
is language that is very close to the mark.
And it smacks of Jorma's beady-eyed, "We're the Big Dog, and you better believe it, or else!" attitude.
If I can paraphrase, "We made attempts (Stop here, and notice the plural). . . . to settle with these QCOM wannabees, and they wouldn't fall for our two-bit offer.
So, in accordance with our long-standing policy, we're making their lives miserable.
Damn the consequences! Lawyers! Full speed ahead!"
As usual, Sir Dog, thanks so much for your trouble.
