Patent trolls are nothing new. They may have even existed as long as it became profitable to sue people for patent infringement. Of late, however, they have increased in their aggressiveness and boldness, whether out of desperation or out of greed. Case in point this latest patent lawsuit levied upon Apple by a Texas company named Corydoras Technologies, LLC. Its beef is that all of Apple's iPhones, and some of its iPads, can make calls, take selfies, do video chats, and block incoming calls. Practically what makes a smartphone a smartphone.
