The allegations and the counter allegations make for a brief interesting read.

Qualcomm Inc has hit back hard at Apple Inc’s charges that were made in its January lawsuit, stating that the U.S. company had breached multiple agreements and had encouraged regulatory attacks on its business in various jurisdictions around the world by making false statements.

Earlier this year, Apple had filed a lawsuit against Qualcomm stating that the chip manufacturer had overcharged for its products and had refused to pay $1 billion in promised rebates.

Following the lawsuit, the U.S. government had also accused the chip manufacturer of resorting to anticompetitive tactics to maintain a monopoly in key technologies in the semiconductors industry which are widely used in mobile phones.

“It (Apple) has launched a global attack on Qualcomm and is attempting to use its enormous market power to coerce unfair and unreasonable license terms from Qualcomm,” said Qualcomm in a statement.

The company has filed counterclaims to Apple’s lawsuit with the U.S. District Court for the Southern District of California.

In its statement, Qualcomm stated that Apple had interfered in its agreements with other licensees that manufacture iPhones and iPads. It said Apple had threatened it in an attempt to prevent it from making any public comparisons about the superior performance of the Qualcomm-powered iPhones, and misrepresented performance differences between iPhones using Qualcomm modems and those using competitor-supplied modems.

Responding to Qualcomm’s allegation, Apple reiterated that Qualcomm had overcharged its royalties and had gained from Apple’s technologies not related to Qualcomm’s patents.

Earlier this year in January, Apple has also filed a lawsuit against Qualcomm in Beijing, alleging that the chipmaker had abused its clout in the chip industry and has sought $145.32 million (1 billion yuan) in damages.
