I'm curious what happens if someone holds a trademark for an unrelated business and then they pivot into a new market. What if she decides she wants to begin to offer rides.. Just curious around trademark law here, any ideas?

For an example of this: http://en.wikipedia.org/wiki/Apple_Corps_v_Apple_Computer

You file your trademark for a particular type of business - it does not give you the right to practice that business elsewhere.

For example, McDonalds Hardware, a fairly popular Hardware business, does not have the right to open up a McDonalds FastFood restaurant.
