My mark “PATENTLY-O” was registered with the USPTO back in January 2006. That means that I am about to hit the deadline for filing a Section 8 trademark renewal application (declaration of use – $100 fee). I'll also be eligible to file a Section 15 declaration of incontestability ($200 fee).
Here's the question: (1) Should I file these? (2) Should I file for protection internationally as well?
