Back in January, Apple filed a $1 billion lawsuit against Qualcomm, claiming the chipmaker maker was charging it for patents it “had nothing to do with”.

In its suit Apple also alleged that “the more Apple innovates with unique features such as TouchID, advanced displays, and cameras, to name just a few, the more money Qualcomm collects for no reason and the more expensive it becomes for Apple to fund these innovations.”

Qualcomm was rumoured to be considering legal action for some time now, and last night it laced up its boxing gloves and stepped into the ring with Apple.

The chipmaker has countersued, denying each and every allegation made in Apple’s suit alleging instead that the iPhone maker is in breach of contract and that it is deliberately misrepresenting the facts. It also alleges that Apple’s original suit is simply a ploy to force Qualcomm to lower royalties on its contribution to Apple’s technology.

“Apple’s goal is clear — to leverage its immense power to force Qualcomm into accepting less than fair value for the patented technologies that have led innovation in cellular technology and helped Apple generate more than $760 billion in iPhone sales,” Qualcomm said it in its suit.

Qualcomm’s executive VP and general counsel Don Rosenberg also had some pretty combative words for Apple.

“Over the last 10 years, Apple has played a significant role in bringing the benefits of mobile technology to consumers with its popular products and services,” said Rosenberg.

“But Apple could not have built the incredible iPhone franchise that has made it the most profitable company in the world, capturing over 90 percent of smartphone profits, without relying upon Qualcomm’s fundamental cellular technologies. Now, after a decade of historic growth, Apple refuses to acknowledge the well established and continuing value of those technologies,” Rosenberg said.

Qualcomm and Apple have worked together for years with the former providing the chipsets for pretty much every iPhone and iPad iteration since the beginning. Ahead of the iPhone 7 launch, however, Apple has started using chips from both Qualcomm and Intel. How this legal kerfuffle will affect the next iPhone launch remains to be seen.
