South Korea-based Samsung has filed a motion to get access on Apple's upcoming devices such as iPhone 5 and iPad 3, as a part of patent dispute between the two electronics giants.

Apple and Samsung depend on each other for their businesses as several key components of Apple products are manufactured by Samsung. For example, Apple’s A4 and A5 processors are designed by Apple but manufactured by Samsung.

But, the problem started in April when Apple accused Samsung of copying the technology, user interface and ground-breaking style of its devices. Last week, a San Jose Federal Court judge allowed Apple to access prototypes of Samsung’s upcoming devices within 30 days.

In particular, Samsung has been ordered to show its upcoming Galaxy S2, Galaxy Tab 8.9, Galaxy Tab 10.1, Infuse 4G and 4G LTE Droid Charge to Apple.

Now, Samsung wants access to Apple’s upcoming products in hope that it would help it to better prepare its defense against preliminary injunction motion brought against it by Apple for trademark infringement.

Apple knows about Samsung’s product lineup as the South Korean manufacturer has already revealed its upcoming product via press release and photographs, while Apple’s plans to release potential iPhone 5 and iPad 3 are yet to be confirmed by the Cupertino-based gadget maker.
