Microsoft gave a preview of its Windows Phone 8 software in June, and promised the first phones would be on the market by the autumn.
Windows Phone 8 looks similar to, and is built on the same core code as Microsoft's upcoming Windows 8 operating system, but is not the same product. Windows 8, which will run on tablets and PCs, is scheduled to launch on 26 October.
Samsung said the ATIV phone would hit stores in the October-November period but did not give an exact start date.
The Korean corporation also showed off a slew of tablets using Windows 8 software and the second generation of its popular Google Android-based Galaxy Note phone-cum-tablet "phablet" in downtown Berlin.
Samsung has sold some 10 million of its original Galaxy Note devices, creating a new product category which has smaller screen than tablets, but bigger than smartphones.
"I am pretty confident it will even outsell its predecessor," said JK Shin, Samsung's chief of mobile business.
Samsung hopes the new device will take the focus away from its loss of the court case. Apple is now seeking speedy bans on the sale of eight Samsung phones, moving swiftly to turn legal victory into tangible business gain.
Samsung hopes the phablet upgrade will lift any post-Apple gloom. The new version of the Note features a thinner and slightly bigger 5.5-inch screen, quad-core processor, the latest version of the Android operating system called Jellybean, and improved stylus function.
"There won't be huge innovative changes in design, but the Note 2 will feature quite a few improvements and enable Samsung to carry on its strong sales momentum in the category," said Lee Sun-tae, an analyst at NH Investment & Securities.
"With the launch, Samsung will also be trying to turn around downbeat sentiment after the US legal defeat."
Apple did not include the Note and other newly unveiled Samsung products in its original lawsuit. But the company and its lawyers are expected by many legal experts to try and use last week's legal victory to go after future gadgets, especially because the jury found infringing features in Samsung phones such as pinch-and-zoom and bounce-back common in Android.
