So you've picked out a name for your startup. You've done a trademark search, and the name appears to be registrable. In addition to filing a federal trademark application, it's important to register the usernames that match your company name on social networking sites liked Google+.
Google+ was launched in 2011 to challenge Facebook, but it never lived up to its potential. Ambitions were subsequently scaled back, and the network was redesigned in November 2015 to focus on people's interests. Network performance was also optimized for smartphones and tablets. Google is not giving up on this platform and neither should you.
What if someone already has registered your company name as a business page? You can first try to resolve the issue informally with the user in question. If that doesn't work, then you can fill out this online form.
