That's not true, although Samsung did claim this. They lied. Samsung did indeed reply to the request for an injunction, their evidence was presented to the court, and the fact they are lying about it and trying to win a PR fight here only illustrates that they have a weak legal argument and so have to resort to other means:

Appleinsider is your source ? No, Samsung did not get a chance to reply at all. They got to file a preliminary letter without knowing at all what Apple's claims were (From the PCWorld article in the very summary of this post) :
In Düsseldorf, Apple filed the case "ex parte": the judge decided on the infringement claims without a hearing or an opposition brief by the defendant, Samsung. The Korean company only filed a preemptive "protective letter"' without having seen the complaint. This also means that Apple's complaint was the principal evidence on which the judge decided to issue a temporary injunction.
It's AppleInsider that is misrepresenting what actually went down here, don't make the mistake of buying into their biased reporting (really, they are a bad source of objective information).
