Motorola Mobility has been ordered by a US jury to pay US$10.2 million (A$12.8 million) in damages for using Fujifilm's patented technology in its phones without permission.
Fujifilm sued Motorola in 2012, accusing the company of infringing three of its patents on digital camera functions and a fourth patent relating to transmitting data over a wireless connection such as Bluetooth.
The damages the jury ordered this week were less than the US$40 million Fujifilm sought when entering into the trial, which began on April 20.
The jury in San Francisco said Motorola Mobility, a unit of China's Lenovo, proved that three of the disputed patents - two on face recognition and one on wifi-bluetooth - were invalid. Motorola failed to prevail on a patent related to converting color images to monochrome.
"We are pleased with the verdict related to three out of the four patents and are evaluating our options on the one patent on which we did not prevail," Motorola spokesman William Moss said in an email.
A spokeswoman for Fujifilm did not immediately respond to a request for comment.
Motorola, which Lenovo bought from Google last year, had argued that the Fujifilm patents should be canceled because they were not actually new or they were obvious compared to previously patented inventions. The company also argued it already held a license to Bluetooth technology.
