Recently I was wearing something with a W and the little TM, and a friend asked, incredulously, "Can they really trademark the letter W?"
Yes, indeed they can. And looking into the trademark created a good occasion to explore the trademarks resources on the United States Patent and Trademark Office website, particularly the Trademark Electronic Search System (TESS). (I am NOT expert in trademark searching, but I was able to mess around and find some things.)
There are a lot of codes involved in trademark searching. For instance, Goods and Services (the [GS] field) are assigned codes, such as 015 for Musical Instruments (goods) and 037 for Construction and Repair (services). The UW provides a service coded broadly as 041, Education and Entertainment. There are also fields for data like the trademark owner's name [ON]. You use the Word Mark [WM] field to look for marks that are letters, punctuation, and words—like, say, W.
Searching for "university of washington" as the owner, and W in the Word Mark field, I found the trademark (serial number 77091314, filed Jan. 5, 2007; registration number 3377279, registered Feb. 5, 2008):
|The UW's trademarked W.|
I also found trademarked Ws with Huskies, one filed in 1992 and one in 1994.
|Two trademarked Ws with Husky faces.|
Not so fast. Look at all the Ws that our W isn't:
Note that the 16 Ws in the graphic are all universities' Ws. If you broaden the search, you can find Ws for banks, plumbers, and nearly every other kind of business.
This trademark doesn't have any letters or words on it:
|UW Husky trademark, filed in 2000.|
03.01.09 - Coyotes; Hyenas; Jackals; Wolves
03.01.16 - Heads of cats, dogs, wolves, foxes, bears, lions, tigers

And if you're so inclined, show your purple on Friday. It's even good for discounts at some local businesses!
