Patent Litigation Posture

Based on the provided data, AT&T Inc. is an operating company that defends itself against patent infringement lawsuits. It has been a defendant in all five tracked cases and has not been a plaintiff, a litigation posture typical for a large technology corporation. The lawsuits have been filed in venues known for patent litigation, including the Eastern and Western Districts of Texas and the District of Delaware.

The plaintiffs in the tracked cases appear to be patent assertion entities (PAEs). For example, Fleet Connect Solutions LLC is described as a non-practicing entity (NPE) and an entity of Empire IP, a monetization firm. Orthosie Systems, LLC has also been identified in public reports as an NPE asserting patents related to vehicle monitoring. AlmondNet, Inc. is an ad-tech company that actively litigates its patents, having won a significant verdict against Amazon. Portus Singapore Pte Ltd. has also filed numerous patent infringement lawsuits against various technology companies. These cases suggest that AT&T is primarily targeted by entities seeking to license or litigate patents related to technologies used in its extensive operations.
