A big mobile battle is brewing and it is between Samsung and Apple this time around.

Australia Federal Court Justice Annabelle Bennet recently released an order to make Apple produce proof of agreements the company had with Australian carriers namely Vodafone Group Plc (VOD), SingTel Optus Ltd. and Telstra Corp. Alongside with that is the order to grant access to the source code for the iPhone 4S firmware. Samsung requested the source code used for the iPhone 4S firmware so that it could supports its case against Apple in terms of patents for wireless transmissions. In turn, Apple already submitted a 220-page document in response to the source code request but Samsung expressed discontentment regarding this because the company believes that "it was not enough" and a certain file was said to be missing in the document. Andrew Fox, the legal representative for Apple remarked on this new court order saying that "We (Apple) will resist any attempts by our friends to push us into a corner" further describing this request order as a "fishing expedition" on Samsung's part.

Failure to comply on the request means an assertion in Samsung's patent lawsuit against the company.

Samsung Electronics Co. filed a lawsuit against Apple in Australia last Sept. 19 and claims that Apple's products like the iPhone 3GS, iPhone 4 and iPad 2 is infringing its patents. The lawsuit also indicated that the iPhone 4S infringes on three patents that is considered as important in enabling the phone's wireless 3G connectivity. The company is also seeking an order to ban the selling and distribution of these Apple products in Australia. Similar lawsuits were also filed in other countries namely France, Italy, and Japan.

The Samsung lawsuit in Australia was actually a response against Apple's lawsuit to ban the sale of the Samsung Galaxy Tablet 10.1 in the country. Apple's argument states that the wireless patents that the iPhone 4S used are covered by Qualcomm's licensing of wireless patents. Apple was able to receive a favorable decision regarding their lawsuit against Samsung and was successful in banning the Samsung Galaxy Tab 10.1 even before it was released in the market. The same situation could not be described with Samsung's lawsuit because the iPhone 4S was already released in Australia two weeks ago.
