I have a question about a shoe brand (trademark etc).
I own a pair of shoes that my father had as running shoes. I don't think that company exists and there is no tm on the name.
How do i do if i want to start the shoe brand again, is it possible, and do i have to buy the rights to the design and brand or?
the shoes must be almost almost 20 years old.

I know it's not about internet but did'nt know any other site to ask at.
