Thats funny, that is a statement from an Article about Samsung suing Dyson. You said Samsung is being sued by Dyson, Dyson is not currently suing them.

"Last August Dyson issued proceedings against Samsung for a patented appliance steering mechanism on its MotoSync range, which it claimed the Korean manufacturer was infringing.
When Samsung's lawyers presented prior art, which it maintained belonged to the company, Dyson was forced to
withdraw the action that had been filed. It could not pursue the claim due to loopholes in the patent system."
Do you know the difference between past, present and future tense? Samsung is not being currently sued by Dyson, as Dyson withdrew there suit. Samsung is now suing Dyson as they claim the initial suit was frivolous.
