Judge: Apple's new VP could cause 'irreparable harm' to IBM

Unsealed opinion spells out concerns over former IBM exec's role

A US federal judge ordered Apple's newest executive to leave the company just five days after starting work because he might cause "irreparable harm" to his former employer, IBM, unsealed court documents show.

Although US District Court Judge Kenneth Karas ordered Mark Papermaster, a 26-year veteran of IBM, to stop working for Apple on November 7, his opinion explaining the decision was made public only on Friday and posted to the federal court system's database Monday.

In the opinion, Karas explained why he granted IBM's request for a preliminary injunction that blocked Papermaster from working for Apple, where he was to head iPod and iPhone hardware development. Last month, IBM sued Papermaster, claiming that a non-competition agreement he signed in 2006 barred him from working for competitors for a year after leaving the company. According to IBM, Papermaster had information of "highly confidential IBM trade secrets" that would "irreparably harm" the company if he's allowed to work for Apple.

Karas said that the injunction was justified. "Because Mr. Papermaster has been inculcated with some of IBM's most sensitive and closely-guarded technical and strategic secrets, it is no great leap for the Court to find that Plaintiff has met its burden of showing a likelihood of irreparable harm," Karas wrote.

Elsewhere in the opinion, he dismissed Papermaster's contention that Apple and IBM are not competitors, and expressed concern that while Papermaster would not be designing chips for Apple -- something IBM claimed, based on Apple's acquisition of P.A. Semi, a small processor design firm, last April -- his background in processor design at IBM would play a part in his new job.

"It is likely that Mr. Papermaster inevitably will draw upon his experience and expertise in microprocessors and the 'Power' architecture, which he gained from his many years at IBM, and which Apple found so impressive, to make sure that the iPod and iPhone are fitted with the best possible microprocessor technology and at a lower cost," Karas said.

"Indeed, any claim that he would merely use general engineering skills is belied by Apple's focus on Mr. Papermaster's 'spot on' knowledge of semiconductors and microprocessor design," he added.

For the majority of his years at IBM, Papermaster worked in processor design, and eventually became IBM's vice president of microprocessor technology development. Most of his work was on IBM's Power line of CPUs. Ironically, until early 2006, when Apple switched to Intel processors, its desktop and laptop systems ran on IBM's PowerPC chip.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
