AMD and Intel are rivals in the marketplace when it comes to x86 compatible CPUs and graphics processors. AMD and Intel have a cross-license agreement in place that allow AMD to use Intel IP to build x86 compatible processors.

On October 7, AMD announced that it was splitting its holdings into two separate companies. AMD will continue as a designer of CPUs and GPUs. The other company is called The Foundry and will be responsible for manufacturing chips for AMD and other companies.

The new company starts with AMD's chip fabs and the chipmaker will retain a 44.4% stake in The Foundry. The remaining 55.6% of The Foundry will be owned by a pair of Abu Dhabi companies that together invested $5.7 billion.

BetaNews reports that Intel issued a statement saying that it will be investigating whether or not the split of AMD and AMD's resulting minority stake in The Foundry violates the heavily redacted licensing agreement that allows AMD to design and manufacture x86 compatible CPUs.

Intel's Chuck Malloy told BetaNews, "We have an obligation to our shareholders that we protect our intellectual property. We want to make sure their interests have been taken into consideration."

AMD for its part believes that it is not in violation of licensing agreements in place between it and Intel. AMD's Michael Silverman told BetaNews, "We are completely confident the structure of this transaction takes into account our cross-license agreements. Rest assured, we plan to continue respecting Intel's intellectual property rights, just as we expect them to respect ours."

According to eWeek, Hans Mosesmann, a financial analyst with Raymond James, believes that Intel could use the split of AMD and transfer of its IP to The Foundry to pressure AMD to drop long-standing lawsuits it has against Intel.

Mosesmann wrote, "AMD, in our view, is likely violating the Intel x86 cross-license, but we suspect Intel may look the other way as it benefits Intel to have an AMD that will over time have increasing variable costs (good for ASPs). Intel may choose to entice AMD to drop the anti-trust suits against Intel in return for this altruistic gesture.”

It appears that Intel is pressuring AMD to release a non-redacted version of the licensing agreement to the public, at this point only the heavily redacted version is available. AMD maintains that releasing a non-redacted version of the license agreement is not going to happen.

AMD spokesman Phil Hughes said, "It’s a business document and we are not going to negotiate this in the press or the media. This is something that the lawyers have to work out.
