That only you (as a company) are allowed to label it as Rodinal?

Wouldn't that cause the same copyright problems for other companies trying to remake it, if you leave the business?
The former owner of the trademark rights in the USA did not care enough for prolonging his rights. Adox slipped in and finally got the rights granted.

Making and trademarking Rodinal are legally total different things. And in contrast to a patent a trademark can be held for a looong time. But this does not happen automatically. Trademarks cannot get buried so to say with the demise of a company.
