Yes, there are some in Legends. For example:

[Aquaware][1]:

>Aquawear was a brand of swimwear for females that was manufactured by AthleticGal.

[Hypergym][2]:

>HyperGym was the brand name of a line of personal exercise equipment.

[Star Rush][3]:

>Star Rush was a brand linked to interstellar travel and luggage transportation. It had stickers on certain luggage cases at the Tomorrowland Starport.

I'm currently looking for canon examples.
