Intel Corp and Qualcomm Inc have provided US lawyers with source code that will help prove Apple Inc isn'''t infringing patents of Samsung Electronics Co, an Australian lawyer for the maker of iPhones said, reports Reuters.

As part of the patent dispute brought against Apple by Samsung in Australia claiming that many versions of Apple's iPhones infringe on its 3G patents, Apple is seeking to prove that Samsung previously licensed 3G patents to other vendors that it has not licensed to Apple. Apple's argument is that it was extraordinary to deny the same licences to Apple on what it considered to be fair, reasonable and non-discriminatory (FRAND) terms.

In court yesterday it was revealed that on Apple's request, Samsung has been providing the Cupertino company with licensing documents it has with other vendors for those patents. While Apple was hoping to get the full details of these agreements, Apple's counsel said that the information provided wasn't "intelligible", with much missing from the documents, including information about the royalty payments the other vendors made to Samsung for those 3G patents.

Attorneys in the US have inspected the code and Intel and Qualcomm have agreed to provide it to lawyers involved in a patent dispute in Australia, Andrew Fox, Apple's lawyer, said at a hearing in Sydney.
