Twitter has been trying to trademark the word for a while now but has consistently been blocked by the US Patent and Trademark Office because two other companies had already applied for variations of the term.
Back in September, Twitter filed a lawsuit against Twittad, a company that arranges for people to get paid to Tweet. But instead of a long drawn out battle, it turned into a short fight. Yesterday, the Wall Street Journal reported that the two companies have come to an agreement. Twitter will withdraw their lawsuit and Twittad will give them the trademark on the word “Tweet.”
