Apple Inc. climbed 1.9 percent to close at a record high on the first trading day after a U.S. jury found that Samsung Electronics Co. infringed on six of its mobile-device patents.

Shares of Apple, based in Cupertino, Calif., rose to $675.68. Apple has gained 67 percent this year.

A California court on Friday ruled that Samsung, based in South Korea, must pay more than $1.05 billion in damages in the first lawsuit between the dominant global smart-phone rivals to go before a U.S. jury.

A judge scheduled a hearing next month to consider Appleís request for a permanent U.S. sales ban on devices such as the Galaxy S and S II smart phones and the Galaxy Tab 10.1 computer. A ban could undermine Samsungís grip on a smart-phone market valued at $219.1 billion by Bloomberg Industries and set a precedent for rival handset makers that use Google Inc.ís Android operating system.

The court victory poses questions for consumers. Will Samsung phones still be available for sale? Will they be more expensive? Will owners of existing phones need to worry?

The $1.05 billion in damages was less than the $2.5 billion sought, but still a victory for Apple. Meanwhile, the jury rejected Samsungís patent-infringement claims against Apple. An appeal is expected.

For now, hereís what the verdict means for consumers:

Q: Can I still buy a Samsung phone or tablet computer today?

A: Yes. The jury didnít prohibit sales of the devices. However, Apple asked a judge to ban U.S. sales of several Samsung devices. A Sept. 20 hearing has been scheduled. If the judge agrees, that would affect many Samsung devices, but not the most recent ones, such as the Galaxy S III and Galaxy Note smart phones. Most of the two dozen devices covered by the lawsuit arenít sold in meaningful numbers in the U.S.

Q: Was Fridayís verdict final?

A: No. Samsung is challenging it.

Q: If Apple still prevails, will this drive Samsung out of the phone business?

A: Thatís not likely. The verdict doesnít apply outside the United States and doesnít apply to the latest Samsung devices, either. The $1 billion in damages represents 1.5 percent of Samsung Electronics Co.ís annual revenue.

Q: Will this make Samsung phones more expensive?

A: Possibly. Samsung may have to pay Apple substantial royalties on each phone. Consumers will likely pay for that somehow, but it may not be noticeable in stores. Phone companies such as AT&T and Verizon Wireless already subsidize each smart phone by hundreds of dollars to get retail prices down to $99 or $199.

Q: What does this mean for the Samsung phone I already own?

A: This doesnít directly affect phones that have already been sold. In the long run, it could reduce enthusiasm around Android, the operating system from Google that Samsung uses.

Q: What does this mean for other Android phones?

A: Although the ruling applies only to Samsung, it will have an indirect effect on all makers of Android devices.
