Lawyers for Microsoft, Inc. have filed a lawsuit against Google, claiming the company’s new Chrome OS color scheme infringes on the Windows logo color scheme.

Can Microsoft really own “the four colors” used in its logo and prevent others in the industry from using them even if the logo is completely different? One of the basic principles of color trademark laws in the US is that a functional color cannot be trademarked. In other words, if a company makes lawn mowers, they can’t trademark green because green is the color of lawns and is therefore a functional color. Contrary to urban myths, John Deere does not own green. (They did trademark a green paint but that’s their paint formula in a special shade of green.)

Consequently, one could say that colors and especially RGB (red, green, blue) are functional colors of all computer operating systems. Without these colors, we’d be stuck with black and white images and text on our monitors, as was the case many decades ago. I conclude that a multi-colored logo is in fact descriptive.

There’s something else that troubles me about this lawsuit: Four specific colors are in question- not just one color such as Dow Corning’s trademarked pink. The issues of color monopoly and color depletion become quite serious in Microsoft’s claim.

Although Microsoft has filed a patent for the colored logo, that’s completely different than their subsequent claim that they OWN the four colors. If Google’s Chrome logo were four circles in a layout similar to Microsoft’s four rectangles, one could argue consumer confusion. That is not the case with Chrome’s compact circular logo.

A final detail: The four colors are NOT the same! Did you notice that Microsoft uses an orange-red and Google’s Chrome a pure red. Likewise, the greens are completely different.
