Apple recently amended its patent infringement lawsuit which it filed against Samsung in April.

The amended version of Apple's legal finger-pointing included strong language charging Samsung of slavishly copying Apple's designs. FOSS Patents stated that Apple even called Samsung the boldest of all competitors in terms of copying its technology. Apple described Samsung's flagrant replication of its designs as copied' replacing the earlier milder charge misappropriated.

Apple has named some key Samsung products which it deems border on being copycats of Apple devices. The Samsung devices include Samsung Captivate, Continuum, Vibrant, Galaxy S 4G, Epic 4G, Indulge, Mesmerize, Showcase, Fascinate, Nexus S, Gem, Transform, Intercept, and Acclaim smart phones and the Samsung Galaxy Tab tablet.

However, the amended lawsuit also adds some more Samsung devices to the line-up which include Droid Charge, Galaxy Ace, Galaxy Prevail, Galaxy S (i9000), Gravity, Infuse 4G, Nexus S 4G, Replenish, Sidekick, Galaxy Tab 10.1, and Galaxy S II.

Apple's patent infringement lawsuit against Samsung reveals that Apple is nervous about Samsung's product profile. Apple is due to launch its next rendition of iPhone 5 in September probably at the iPod refresh event. And while the lawsuit claims that Samsung products are identical to Apple's iconic devices iPhone, iPod touch and iPad, the underlying fact is that Samsung has a deep product portfolio of Android devices which can give Apple a run for its money.

Apple demanded that Samsung should show the prototypes of its upcoming devices. Samsung counter-sued and demanded that Apple should showcase its upcoming iPhone 5 and iPad 3 devices, an action which Apple termed as harassment.

The lawsuit could be an attempt by Apple to shield its upcoming iPhone 5 from the likes of Samsung Galaxy S2 and Infuse 4G. The delay in launching iPhone 5 is seen as Apple playing catch up with some of the superphones in the Android camp. Until Apple launches its iPhone 5, the only way it can plug users from switching to phones like Samsung Galaxy S 2 is to seek an injection to block Samsung's phones sale.

Here is a list of the top 6 Samsung phones which are making Apple nervous and, thus, have been named in its patent lawsuit:
