Samsung Electronics seems to focus on its latest smartphone, the Galaxy S6 Edge, the variant of the Galaxy S6, documents showed Thursday, as it won a trademark for the "S6 EDGE+" earlier this week. According to the documents posted by the United States Patent and Trademark Office, Samsung Electronics has won the trademark, meaning that the South Korean tech giant may roll out an updated edition of its flagship smartphone.

The Galaxy S6 Edge features the industry's first screen that is curved on both sides. It was an upgrade from the Galaxy Note Edge, which has a curved screen on only one side.

The "S6 EDGE+" could be a larger-screen edition of the Galaxy S6 Edge, just as Apple added "Plus" for bigger editions.

Samsung is anticipated to showcase its next flagship phablet later this year.
