For now, here's what the verdict means for consumers:
Can I still buy a Samsung phone or tablet computer today?
Yes. The jury didn't prohibit sales of the devices. However, responding to a request from the judge, Apple has submitted a list of smartphones that it wants banned from sale in the U.S. A Sept. 20 hearing has been scheduled. If the judge agrees, that would affect many Samsung devices, but not the Galaxy S III and Galaxy Note smartphones. Most of the two dozen devices covered by the lawsuit aren't sold in meaningful numbers in the U.S., but several newer models are on Apple's list.
Was Friday's verdict final?
No. Samsung is challenging it. First, Samsung will ask the trial judge to toss the verdict. Then it will appeal to a court in Washington that specializes in patent appeals. Samsung has vowed to take the fight to the U.S. Supreme Court, if necessary.
If Apple still prevails, will this drive Samsung out of the phone business?
That's not likely. The verdict doesn't apply outside the U.S. The $1 billion in damages represents 1.5 percent of Samsung Electronics Co.'s annual revenue.
Will this make Samsung phones more expensive?
Possibly. Samsung may have to pay Apple substantial royalties on each phone. Consumers probably will pay for that somehow, but it may not be noticeable in stores. Phone companies such as AT&T and Verizon Wireless already subsidize each smartphone by hundreds of dollars to get retail prices down to $99 or $199.
What does this mean for the Samsung phone I already own?
The verdict doesn't directly affect phones that have already been sold, even if they are the models that the judge decides to ban. In the long run, it could reduce enthusiasm around Android, the operating system from Google that Samsung uses in the devices in question. That might mean fewer applications for Android from outside parties. That will take years to play out, but could conceivably affect the resale value of your phone.
Does this mean Samsung phones will look different in the future?
Possibly. The jury dinged Samsung's flagship Galaxy line for copying the overall look and feel of the iPhone and for using the stock icons with rounded corners that come with Android. Also at issue was the way Android can tell the difference between the touch of a single finger and several fingers. Samsung might delay some models to give it time to rework their look and feel.
What does this mean for other Android phones, such as those from LG Electronics Inc., HTC Corp. and Google's Motorola Mobility?
Although the ruling applies only to Samsung, it will have an indirect effect on all makers of Android devices. Apple could go after them with arguments similar to the ones used against Samsung. But the ruling Friday is not precedential, meaning that other courts could reach completely different decisions.
Most likely, makers of Android phones will take more care to make their phones distinguishable from the iPhone.
What does this mean for Android devices around the world?
Apple and Samsung are waging similar battles in other countries. On the same day Samsung lost in the U.S., it partially won a fight in South Korea. A Seoul court imposed a partial ban on South Korean sales of products from both companies. That verdict didn't affect the latest models, either.
What does this mean for Apple?
Analysts say it could help Apple gain market share at the expense of Android phones, if these have to avoid some attractive and easy-to-use features introduced by Apple.
Despite being a driving force in phone development since the iPhone was launched in 2007, Apple has only 19 percent of the worldwide smartphone market, according to IDC. The high price of the iPhone keeps it out of the reach of many consumers. Android phones have 64 percent of the market.
