Apple has made a number of alterations to its patent infringement filing against Samsung in an attempt to strengthen its case and prevent the Korean manufacturer gaining access to unreleased products.
In the amended filing, Apple accuses Samsung of creating "products that blatantly imitate the appearance of Apple's products to capitalise on Apple's success".
The iPhone maker said previously that Samsung had been "misappropriating" its designs, but now alleges "copying" in an attempt to add weight to its case, according to software patents expert Florian Mueller.
Apple specifically referred to the iPhone, iPhone 3G and iPhone 4 models to block Samsung's lawyers from getting access to the iPad 3 and iPhone 5 prototypes, he explained.
"By making it clear that only particular generations of the iPad and iPhone product lines are relevant to the case, Apple tries to make it even harder for Samsung to convince the court that it should get access to future Apple products," Mueller said on the Foss Patents Blog.
Apple has also amended the list of patents that it believes Samsung to be using without permission.
Two patents have been dropped from the litigation, but three have been added. These include two hardware patents in relation to touch-screen technology and a software patent concerning content display.
Finally, Apple has formally added high-profile devices such as the Galaxy Tab 10.1, Galaxy S2, Droid Charge and Nexus S 4G to the list of alleged infringing products.
Apple is due to receive samples on Friday of the Galaxy S2, Galaxy Tab 8.9, Galaxy Tab 10.1, Infuse 4G and Infuse 4G LTE - also known as the Droid Charge - together with packaging and inserts.
Apple will then decide whether to request a preliminary injunction, which Mueller believes is reasonably probable, although a settlement is also possible.
"I think what Apple wants more than anything else is to force Samsung to change the design of the Galaxy product line so it will be more distinguishable from the iPhone and the iPad," he told V3.co.uk.
"Royalties could also be part of the settlement, but it's too early to figure how high they would be because it remains to be seen which patents the parties assert against each other in the further process. We may still see some more assertions during the next couple of months or so."
