We're not sure this was the right move on Apple's part, but the company has in fact filed for the iOS Notification Center patent with both the U.S. Patent and Trademark Office (USPTO) and the World Intellectual Property Organization. While the document tries to outline the feature in excruciating detail, even the most ardent Apple fans would have to admit that the feature is way too similar to Google's Notification Bar in Android.
To make matters worse, Google got there first as its Android software had the Notification Bar in place before Apple introduced Notification Center in iOS 5, which was released in June 2011.
Maybe Apple hastily moved to file for this patent because Samsung last month filed a lawsuit in its home country against Apple regarding the iOS Notification Center, arguing the feature infringes on one of its active patents?
