I worked at a trademark search and brand-protection company for a few years, and we never used D&B. We scraped from every secretary of state in the US and the federal patent and trademark office, and got some info from LexisNexis. We had a mess of regular expressions that had to be updated any time a secretary of state changed their website. But in the end, we had a reasonably complete set of information on all registered corporations and DBA registrations in the country, which was updated at least monthly. We certainly had a record for every company that had a registered trademark. Apple could certainly do that work itself, at a fraction of the cost of whatever it pays D&B. Any Joe Schmoe in the country can look at a business name, go to the secretary of state of the state they claim to be registered in, and verify the detail, which always includes the name and address of the registered agent, and most of the time also includes the principals of the corporation. D&B is almost completely pointless in 2018.
