NEW YORK (

TheStreet

) -- Even by its own headline-grabbing standards,

Apple

(AAPL) - Get Report

has had a big week, marked by a major

patent victory

over rival

Samsung

and another record-high stock price.

Late on Friday a jury in San Jose, Calif., awarded Apple

$1.05 billion

in the closely-watched patent case, ruling that the Korean phone giant had "willfully" infringed a number of "valid" Apple iPhone patents.

The landmark case could have

major implications

on the technology landscape, bolstering Apple's confidence in the ongoing tech patent wars.

Samsung, however, looks likely to appeal the ruling.

Apple shares also hit another all-time high this week when they traded at $674.88 on Tuesday.

The iPhone maker also became the most valuable company in history in terms of market cap on Monday, when it surpassed the $620.58 billion valuation set by

Microsoft

(MSFT) - Get Report

in 1999, although the software giant would still hold the record, if the valuation was

adjusted

for the effects of inflation.

Additionally, Friday marked the

one-year anniversary

of Tim Cook's appointment as Apple CEO.

The overwhelming majority of respondents to

TheStreet's

poll

on the Apple chief say that Cook's doing a great job.

A bit less than 75% of the respondents gave Cook a thumbs up, with only 2% describing the former Apple COO as a "disappointment." A little more than 23% of

TheStreet's

readers, however, said they're undecided on the Apple chief, noting that "the jury's still out."

Cook faced the daunting prospect of replacing Apple's iconic co-founder Steve Jobs when he stepped up to the CEO's role last year. The 51-year old, however, has overseen successful launches for the iPhone 4S and the new iPad, as well a major Mac refresh. Cook is also expected to debut the eagerly anticipated iPhone 5 next month. Apple shares have also climbed more than 86% on Cook's watch.

Shares of the Cupertino, Calif.-based firm rose 2.3% this week to close at $663.22. Apple had a valuation of $621.71 billion at Friday's close.

HP

(HPQ) - Get Report

shares slumped after the No. 1 PC maker reported disappointing

third-quarter results

on Wednesday.

The Palo Alto, Calif.-based company brought in sales of $29.7 billion, down from $31.2 billion in the prior year's quarter, and below analysts' forecast of $30.1 billion.

Declining PC and printing sales, in particular, weighed heavily on the company's top line. Revenue from HP's Personal Systems Group (PSG) declined 10% in the third quarter, while Imaging and Printing Group (IPG) revenue was down 3%.

Excluding items, HP earned $1.00 a share, in line with its preannouncement earlier this month, but down from $1.10 a share a year earlier. HP also lowered its guidance.

Although external factors such as macroeconomic headwinds impacted HP's results the company acknowledged that it needs to do a

better job

of executing against its goals. The company is still in the early stages of its turnaround, according to CEO Meg Whitman.

HP shares slumped 9.9% to end the week at $17.58.

HP's results came hot on the heels of underwhelming

second-quarter results

and weak guidance from

Dell

(DELL) - Get Report

on Tuesday.

The Round Rock, Texas-based company reported revenue of $14.5 billion, down from $15.7 billion in the same period last year, and less than analysts' forecast of $14.64 billion.

Excluding items, Dell earned 50 cents a share, compared to 54 cents a share in the prior year's quarter. Analysts surveyed by

Thomson Reuters

were looking for earnings of 45 cents a share.

With PC sales under pressure, Dell expects its third-quarter revenue to slip between 2% and 5% sequentially. Excluding items, the HP rival also adjusted its full-year earnings guidance to $1.70 a share, which includes a 2- to 3-cent dilutive impact from Dell's pending acquisition of

Quest Software

(QSFT)

. Analysts surveyed by

Thomson Reuters

were looking for earnings of $1.90 a share.

Dell shares ended the week down 7.9% at $11.26.

PayPal

, owned by

eBay

(EBAY) - Get Report

, announced a

deal

with

Discover Financial Services

(DFS) - Get Report

on Tuesday.

The deal, which is seen as a shot at rival

Square

in the mobile payments war, brings PayPal access to the 7 million merchants across the country who take Discover, starting in the second quarter of 2013.

Earlier this month,

Square

announced a

partnership

with

Starbucks

(SBUX) - Get Report

to let customers pay with Square's app at the coffee giant's 7,000 U.S. locations.

eBay shares crept up 0.5% to close at $47.10 on Friday.

Salesforce.com

(CRM) - Get Report

flew past Wall Street's estimates in its

second-quarter results

, released after market close on Thursday, although the company's shares tanked on weaker-than-expected profit guidance.

Shares of the customer relationship management (CRM) specialist, one of

TheStreet's

top cloud stocks

, ended the week up 0.9% at $148.54.

Amazon

(AMZN) - Get Report

sent out invitations this week to a major press event taking place in Santa Monica, Calif. on Sept. 6, fuelling speculation that the

new Kindle Fire

is on deck.

Shares of Amazon ended the week up 1.89% at $245.74.
