Samsung have fired back at Apple after Apple slapped them with a lawsuit saying that Samsung have copied their iPhone and iPad designs with the Galaxy phone and Galaxy Tab range. Samsung provide Apple with semiconductor chips and display panels for Apple's mobile products and have not (to this point in time) sued Apple for infringement but obviously Apple have pushed Samsung over the edge and now they're fighting back saying:

"We have no choice but to respond strongly this time".

Them be fighting words! Instead of directly countering Apple's claims, Samsung made a claim of their own saying Apple are infringing on their wireless patents. Samsung said in a statement:

Samsung will respond actively to this legal action taken against us through appropriate legal measures to protect our intellectual property.

Keep in mind that Apple was Samsung's second largest customer last year with over $5.68 billion in purchases.
