The publisher of RF, ParkerVision that comes from Florida submitted the application to ITC and Florida regional court to prosecute Apple, Samsung, LG and Qualcomm Incorporated as they infringed its wireless networking patent.

ParkerVision claimed that the wireless receivers made by Qualcomm and Samsung violated its wireless networking patent. Apple, Samsung and LG all apply the infringed Qualcomm chips for their mobile devices. The Sahnnon 928 RF reciever which is made by Samsung will be further checked as well.

The involved patents inlcude No.6879817,No.7929638, No.8571135 and No9118528. They are related to the wireless radio frequency technology and its applications usage. ParkerVision respectively sues Qualcomm and Samsung concern the patent infringement.

ParkerVision sued Qualcomm in 2011 for the first time, but it could not prove the evidence. In 2013, the Jury of Florida court ruled Qualcomm infringed ParkerVision’s patent and fined $173 million, but this judgment was objective later.

In the document ParkerVision submitted, it asked for prohibiting to export those infringed products to overseas. The involved Apple products are iPhone 6, iPhone 6, iPad Air 2 and other products.

ParkerVision is a listed company that established in 1989 and it specializes in designing wireless chips. Most of its revenue is from the technology licensing business. The infringement damages its advantage in this industry, so it has to appeal to the court.

ParkerVision’s future seems to be negative. It only signed one contract in the first three quarters this year. The revenue only has $55 million.
