Specifically, Apple says that Qualcomm's now-dated Snapdragon 800 and 820 processors - used in a number of Android phones from the likes of Google and Samsung - infringe on these patents, but Qualcomm is the only firm named in the countersuit.
In January, Apple sued Qualcomm for almost US$1 billion in patent royalty rebates that Qualcomm allegedly withheld from Apple.
APPLE HAS FIRED a countersuit in the direction of chipmaker Qualcomm, alleging the firm's Snapdragon chips infringe on eight of its battery patents.
The three cases filed Thursday were all filed in US District Court for the Southern District of California in San Diego.
Apple is filing these new patent infringement claims to get Qualcomm's own patent claims dismissed. Unless the two settle their differences out of court, it may take years until we hear final verdicts in these patent lawsuits - and these trials are bound to become even more complicated. Companies like Apple have this routine of filing and receiving technology patents but that is only there is to it.

"Apple's patents are critical to what consumers value in a handset - cutting-edge functionality with superior battery life", said the company in the lawsuit.
The Apple patents involve ensuring each part of a phone's processor draws only the minimum power needed, turning off parts of the processor when they are not needed and making sleep and wake functions work better.
Qualcomm filed its patent infringement lawsuit at the same time it filed a complaint with the U.S. International Trade Commission seeking to ban the import of Apple iPhones that use competing Intel Corp chips because of the alleged patent violations.
Qualcomm in November sued Apple over an alleged breach of a software agreement between the two companies. In a connected case, Qualcomm charged the contract manufacturers that create Apple's devices, however Apple associated with the team to defend them.
