The color(s) red, white, and black is/are claimed as a feature of the mark.
The mark consists of the upper-case letters "PERI", followed by a hyphen; "IMPLANT", followed by a hyphen; and "ITIS" - all in black letters and arranged in three stacked horizontal lines, on a white background which includes a red circle surrounding the text and a red forward slash running through the circle and crossing - diagonally, behind at least one letter, on each line. The white area surrounding the outer aspect of the red circle is not part of the mark, and is only used to indicate the edge of the design.
