Many of today's smartphones share similar features, from responsive touchscreens that let users unlock the phone with a flick of a finger, to pop-up animations that offer a shortcut to dialing a number or storing it in a digital address book.
Those similarities are at the center of an array of patent disputes as Apple and Samsung Electronics sue each other in courts and trade offices around the world.
The companies' most recent legal fight all but concluded on Friday, when a California jury found that Samsung copied some of Apple's smartphone features. The panel also concluded that Apple illegally used one of Samsung's patents in creating the iPhone 4 and 5.
All told, the jury awarded Samsung $158,400 and Apple $119 million, far less than the $2.2 billion the company sought.
Jurors were ordered to return to court Monday to continue deliberations on a minor matter that could result in a higher award for Apple.
Before determining whether the companies copied phone technologies, jurors had to consider several patents. Here's a look at select patents and the jury's conclusions:
—Official description: System and method for performing an action on a structure in computer-generated data.
