Anything sold can have trademarks and brand names. Even things that seem to be as boring as it gets, or as difficult to market as they come.
I have written before about the trademarks for manure brands and slaughtering services. And any type of brand can have a creative brand name or slogan or logo. I have written before about libraries and electrical supply companies.
Even sewing awls can have creative names!

And toilet paper brands too!

In short, anything can have a great – creative and memorable – brand name.
