Apple has revealed that it has inked a patent-licensing agreement with Microsoft.
Patent licensing director Boris Teksler testified in court that Microsoft has licensed iPhone and iPad design patents from Apple.
Teksler told the jury that licensing terms of the deal included an "anti-cloning agreement", which would have prevented Microsoft from copying Apple devices outright.
His testimony comes at the same time as court document leaks, showing the terms of licensing Apple offered to Samsung prior to its lawsuit.
"There was no right with respect to these design patents to build clones of any type," Teksler said of the Microsoft agreement, according to Reuters.
Microsoft's accord with Apple reportedly includes a clause which would prohibit any cloning of Apple products. The design patents licensed by Microsoft could be used as a bigger part of a unique design but outright copying is prohibited by the agreement.
Samsung and Apple have been fighting in court about the design patents at the root of Microsoft's agreement since last year.
When contacted by V3, a Microsoft spokesperson declined to comment on the licensing pact.
News of Microsoft's patent licensing contract comes on the heels of a release of documents detailing Apple's attempts to license patents to Samsung.
In 2010, Apple and Samsung met to discuss potential licensing terms as a way to avoid litigation. Documents from those discussions show that Apple was willing to offer licences on certain patents for the price of $30 per Samsung smartphone.
"Samsung chose to embrace and imitate Apple's iPhone archetype. Apple would have preferred Samsung request a licence to do this in advance," Apple wrote in peace summit documents shown to Samsung.
"Because Samsung is a strategic supplier to Apple, we are prepared to offer a royalty-bearing licence for this category of device"
The documents make no mention of licensing design patents. However, Apple testimony from the current trial indicates that the iPhone designs were still in the process of getting patented at the time of the Samsung talks.
Apple was not available for comment at the time of this writing.
Apple opened its arguments last week by telling the jury that the iPhone caused a "crisis of design" for Samsung.
