In its complaint, obtained by MacRumors, Rembrandt alleges that all Apple products that support Bluetooth 2.0 or newer with Enhanced Data Rate, including the iPhone 3GS and newer, all iPad and Apple Watch models, several Mac models, HomePod, and others, infringe on U.S. Patent Nos. 8,457,228 and 8,023,580.
Enhanced Data Rate, often shortened to EDR, is a technology that allows for faster Bluetooth data transmission speeds.
The asserted patents describe wireless communication techniques that appear to be related to Bluetooth with EDR, so the alleged infringement could extend to virtually any Bluetooth-enabled device. The same Eastern Texas court ordered Samsung to pay $11 million to Rembrandt last year over the same two patents.
Rembrandt is not the original assignee of the patents, which both expired on December 4, 2018, according to its complaint. The entity says it is still entitled to damages for infringement that occurred prior to the expiration of the patents.
Rembrandt is seeking an award of damages stemming from Apple's infringement in an amount to be proven at trial. In the Samsung case, a jury calculated damages based on a royalty rate of approximately five-and-a-half cents per infringing device. Rembrandt has requested a jury trial against Apple as well.
The case has been assigned to U.S. District Judge Rodney Gilstrap, who also presided over the Samsung trial.
