This is all part of an ongoing legal battle. In January, a a jury in San Diego, California jury ruled that Apple must pay WiLan $85 million for patent infringement.
In August 2018, a federal jury in California awarded Canadian patent licensing company WiLan $145.1 million in damages against Apple for patent infringement. However, in January 2019 this was slashed to $10 million by a California jury.
The lawsuits concern Apple’s alleged use of WiLAn’s 4G and LTE technologies found in most of Apple’s products. WiLan was established in 1992 to develop and commercialize technology that made low-cost, high-speed wireless networking a reality.
Apple has urged the Federal Circuit to overturn an $85 million verdict against it for infringing WiLAN’s patented wireless technology, saying that the licensing firm has been “stretching its patents” and otherwise “overreaching” at every stage in the case, reports Law360 (a subscription is required to read the entire article).
