FireFox-trademark picture Firefox to see how the trademark picture in the trademark network is upside down.
I often worry about this problem, too. In the source code queried in FIREFOX, there is a code filter:FlipV, and the image will be normal after inversion
But it only supports IE, so it looks normal to display the inverted image in IE
But other browsers don't support this code, and the Trademark Office website doesn't seem to have considered this problem ...
