Today’s mobile roundup features Apple’s legal battles against Samsung, Motorola and Proview, AT&T’s new “unlimited data” policy, Sprint and Chrysler partner up, worm attacking Android devices, and a tablet especially made for kids.

Apple

Both Apple and Samsung lost their cases for patents in the Regional Court of Mannheim this week.  Samsung lost its bid to protect mathematical coding procedures, while Apple lost its case over features for unlocking touch screens.

Presiding Judge Andreas Voss stated that both failed to show that the other infringed their patent.  Samsuing lost the case because “the standard doesn’t protect the result but the way to reach the code,” while Apple lost because Samsung’s devices “don’t use a displayed pre- determined path on the touch screen,” Voss stated.

But Apple was victorious in one of their cases against Motorola Mobility, as they were granted an injunction against Motorola’s use of photo management software on an electronic device.

Apple declined to comment while Motorola stated that “Yesterday’s ruling in Munich, Germany on the patent litigation brought by Apple concerns a software feature associated with performing certain functions when viewing photos in a ‘zoomed in’ mode on mobile devices,” said a spokesperson.

“We note that the Court ruled that performing the functions in a ‘zoomed out’ mode does not infringe on this patent. We expect no impact to supply or future sales as we have already implemented a new way to view photos on our products that does not interfere with the user experience.”

As for the Apple-Proview dispute, Proview International Holdings Ltd. lawyer Roger Xie stated that the two companies haven’t made contact yet to settle the issue.  Proview is more intent on settling than going through all the brutal court battles, since they’re already knee deep in financial woes, but we all know Apple loves to fight for their rights in court.

“Up to now, we didn’t have any formal negotiations with Apple,” Xie said in a telephone interview today. “I hope they will positively contact us and make an appointment with us about formal negotiations out of court. It would be useful.”

AT&T

To appease the angry mob of AT&T “unlimited data plan” subscribers who experienced throttling in service id they’re a part of the 5% heavy data user, the service provider announced a new plan of slowing down service if they reach 3 gigabytes of usage within a billing cycle.  This made people relax a bit as they now know what to avoid to prevent slowing of service.

“Our unlimited plan customers have told us they want more clarity around how the program works and what they can expect,” AT&T said in a statement.

Sprint

Sprint announced a strategic wireless partnership with Chrysler Group for their Uconnect Program.

“Chrysler Group and Sprint share a mutual commitment to the delivery of advanced, next-generation connected vehicle and telematics services,” said Matt Carter, president — Wholesale and Emerging Solutions, Sprint. “Sprint is delighted to be chosen for this unique alliance as we develop a robust wireless engine for Chrysler Group’s Uconnect program.”

Android

According to Kaspersky Lab, the Russian computer security company, this year, they are expecting a mass of worm attacks on Android devices.  Worms are notoriously known for stealing important data from computers, and they are now coming to Android devices.

“It is the root exploits for Android that started the mass use exploitation of vulnerabilities in mobile operating systems, and they are the go-to choice for Chinese virus writers,” Kaspersky Lab Senior Malware Analyst Denis Maslennikov said. “Many users do not yet realize that they are being victims of cyber crime.”

On a lighter note, there’s a new Android Ice Cream Sandwich tablet made especially for kids.  Archos unveiled the Child Pad which might cost $129 or around £99.  The Child Pad features a 1GHz processor and, a first at this price, 1GB RAM, and a 7-inch display with a 800×480 pixels screen resolution.

Though this tablet doesn’t have an access to the Android Market, they have their own “Kids App Store” powered by Appslib, containing 10,000 apps scattered amongst 14 categories.

The Child Pad comes bundles with 28 games including Angry Birds, Pig Rush and Flight Frenzy and Archos stated that they designed the tablet to comply with CIPA and COPPA regulations.
