According to Theverge, the U.S. Patent and Trademark Office has issued a patent for the appearance of Apple's rounded rectangle, patent number D670286. Previously, there was a lot of discussion about the patent of rounded rectangle. Now, this patent has finally come true. The following figure is the design diagram disclosed by Theverge, in which only the solid line is the patent protection content, and the dotted line is the schematic diagram of enhancement effect. Different from the previous design patents for iPad and iPhone, the previous patent design contains at least one additional feature solid line, such as Home key, rear surface outline, side outline or screen, but all of them are represented by dotted lines here, which shows that Apple did not put the above content into the discussion scope in order to highlight the design of "rounded rectangle".

Theverge pointed out that the concept of rounded rectangle is very broad, for example, the scale of the horizontal and vertical lines of the border in the figure is also within its protection range. At the same time, because the patent content is too broad, the practical value of the patent is not very large. Although Apple has obtained the patent, the patent is too broad, which may become the reason for the litigant to request the judge or jury to reject the patent, or make the public opinion biased towards the litigant.
