NEW YORK ( TheStreet) -- Even by its own headline-grabbing standards, Apple ( AAPL) 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) 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'spoll 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) 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. > > Bull or Bear?

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.
