Ironworks Patents, fresh off a nearly $11 million patent win over Apple Inc. this summer, is suing the tech giant again, alleging continued infringement with its later-generation iPhones, including iPhone 8 models and the iPhone X.

In a complaint filed Oct. 6 in Delaware federal court, the Chicago-based nonpracticing entity said it was suing out of an “abundance of caution” to preserve its rights to seek damages on the recent iPhone models.
