It would appear that BlackBerry are now on the patent offensive. After filing a patent suit against Avaya two weeks ago, BlackBerry has filed two patent lawsuits in the United States, this time against BLU Products.

Filed on August 16, 2016 in the U.S. District Court for the Southern District of Florida, BlackBerry claims BLU has infringed fifteen of its U.S. patents,

The complaint states that BlackBerry offered BLU a patent license in a letter dated November 21, 2015 and a follow up letter December 8, 2015, but the company failed to respond.

The first case alleges seven patents relate to battery, API, messaging, and imaging technologies. The second case alleges eight patents, which are Standards Essential Patents (SEPs) and were declared to the standards setting organizations (SSOs) when the various working groups were developing new technologies.
