At last, it's over. InterDigital, which is best known for its episodes in the courtroom with Samsung and Nokia, has finally reached an agreement with the former firm. The two have been at each other's throats since April of last year regarding patents allegedly used in some of Sammy's more sophisticated phones. The decision was reached just a day before the US International Trade Commission was set to rule on whether to recommend barring affected Samsung imports altogether, which we can assure you was not at all coincidental. There's been no public disclosure of settlement value, though one analyst at Hilliard Lyons estimates that Samsung will be coughing up $400 to $500 million over the next five years to make this problem go away. Talk about a recurring nightmare.
