The Oklahoma energy company Oneok filed a lawsuit this week against Twitter for allegedly allowing an impostor to create an account on the service. But the lawsuit, filed in the northern district of Oklahoma on Tuesday, has already been dismissed.

Oneok alleged in its court papers that someone who was not affiliated with the company created a Twitter account under the Oneok name and then posted at least two tweets. The tweets also allegedly displayed Oneok's diamond-shaped logo, which is also trademarked.

"These tweets have the appearance of being an official statement issued by Oneok on the Twitter system," the complaint alleges. Oneok added that the account could harm its reputation.

The company said it unsuccessfully sought to obtain contact information for the account holder. The energy company also alleged that it asked Twitter to transfer the account.

The court papers do not indicate why the case was dismissed, but an Oneok spokesperson said the company withdrew the case because the account had been transferred to the company.

This case marks at least the second time Twitter has been sued for allegedly hosting a fake account. Earlier this year, St. Louis Cardinals manager Tony LaRussa sued Twitter over a parody page. LaRussa also dropped the lawsuit shortly after it was filed.

Twitter says in its terms of service that it will suspend accounts that use misleading business names or logos.
