True, but it is a trial by jury and Samsung is understandably more worried about the opinion of the jury than the judge. IANAL, but I reckon the worst that can happen is a mistrial and they will have a harder time now finding new jurors that have not been exposed to news media stories regarding this case. Plus, I think that in a retrial Samsung would be allowed to readmit this material since the original reason for it's dismissal was timeliness of submission.

Fortunately for Samsung, the court can't really get them if they didn't break any rules. :)
