Not technically, but if I recall, during the Motorola acquisition, when the terms of the deal included requiring Google's okay to do any patent lawsuits while the acquisition was pending, Motorola started several patent lawsuits non-defensively.

Moto went after Apple and Microsoft that were threatening and trolling and suing Android vendors. Those cases were clearly defensive.

But they were surely trolling cases fought with garbage patents on Moto's side. Google grossly overestimated the quality of Motorola's portfolio and was blinded by the sheer number of mostly worthless patents Moto had.
