If you own registered trademarks and service marks, ignore ALL private firms requesting money to “protect them,” or extend them, or apply them in foreign countries. They are all scams. Most are overseas in Slovakia or Belarus or Kazakistan, but some are domestic (United States Trademark Maintenance Service). They will print in small letters that they are not a government agency in some area almost impossible to find. And they will try to extort thousands of dollars for their “protection.”
Find a good trademark attorney, have that attorney file and extend for you at the appropriate intervals, and you’ll be doing everything you need to for about $250 an hour.
It’s amazing how many people try to rob and steal thinking the rest of us are even stupider than they are. Trademark that.
