Apple-Motorola patent dispute revived

US Judge Richard A. Posner scheduled an injunction hearing regarding the Apple-Motorola Mobility patent dispute after raising the possibility that the case may be dismissed as the two haven’t established their rights to relief.

“The parties should be prepared to address the possibility of substitution for an injunction of an equitable decree for a reasonable royalty going forward,” the judge said.

The hearing is scheduled on June 20, Wednesday, and both parties will be given a chance to argue for injunctive relief against alleged patent infringement by the other.  Last week, Judge Posner stated that the case should be dismissed but decided that he would allot another week before he makes his judgement.  In his issued statement, Judge Posner stated that Motorola should be prepared to address the bearing of FRAND (fair, reasonable and non-discriminatory) on the injunction analysis.

Microsoft to launch tablet on Monday

Microsoft sent out invites for their press event on Monday, June 18, in Los Angeles for a “major announcement.”  There are no clues yet as to what Microsoft would be announcing, but rumor has it that the software giant will be announcing their very own Windows 8 tablet, as in Microsoft Windows 8 tablet, not a tablet made by some other OEM that runs on Windows 8.  Microsoft wants what Apple wants, they want to produce both software and hardware.

In other Microsoft news, they’re said to be eyeing Yammer Inc., the social network for businesses, for the hefty price of $1.2 billion.  Microsoft wants to upgrade Microsoft Office and they see Yammer as the perfect fit for their plan to go social.  It’s a growing area of interest right now for cloud service providers, and Microsoft would be joining a buying spree recently initiated by SAP and Oracle.

Dropbox updates iOS app

Cloud service provider Dropbox updated their iPhone app with automatic photo and video upload from their device’s camera roll.  The new features works over Wi-Fi or 3G.  The feature isn’t something new for Android users, as it’s been available for some time now.

Users just have to update their Dropbox app to the latest version, v.1.5, or if they don’t have it yet, they can download the latest version from Apple’s App Store.  When the user opens the app for the first time, or after the update, he will be prompted to enable automatic upload.  A user has the option of sharing previously taken photos or only the photos taken in the future.

Nokia stocks’ major fall

A Nokia buyout seems more and more likely as their stocks plunged 18% after forecasting a wider second-quarter operating loss from handsets, and saying it will cut as many as 10,000 jobs.

“The key question is, can they do something to turn this into a growth business again?” Michael Mahoney, senior managing director at Falcon Point in San Francisco, said in a telephone interview. “If they can just make it grow, even a little bit, it’s very cheap.”

Nokia was the largest phone maker for years but as more people embrace Apple and Samsung devices, interest in their products has continuously declined.

FCC review mobile radiation

The Federal Communications Commission is set to review their standards regarding the safety of mobile phone use as more and more people use their devices for longer periods of time.

“Our action today is a routine review of our standards,” FCC spokesman Tammy Sun said. “We are confident that, as set, the emissions guidelines for devices pose no risks to consumers.”

The FCC last updated their guidelines in 1996 when they set the maximum radiation-exposure levels, which are based on the amount of heat emitted by mobile phones.  If there will be changes in their guidelines, it could mean millions for OEMs as they have to change their mobile phones in order to comply with the FCC’s standards in order for their devices to be market-ready.

“Any changes in the rules will have an impact on handset vendors,” said CW Cheung, the Asia-Pacific head of consulting for telecoms at Ovum, which advises companies in the telecommunications industry. “As most vendors are based outside the U.S., it could also become a trade issue.”
