Thomson Reuters, one of the biggest news gathering and public relations companies, has purchased Mark Monitor for an undisclosed sum, the companies announced yesterday.

Mark Monitor is a service that helps brands track what’s said about them in public and offers trademark and copyright protection, domain management, and more. The company has more than 400 employees across five countries, and its clients include about half of the top Fortune 100 brands.

Thomson Reuters said it will add Mark Monitor’s services to its own to enhance the quality of protection offered to its vast number of clients. As part of the deal, the Mark Monitor team, including president and CEO Irfan Salim, will join Thomson Reuters.

Founded in 2006, the San Francisco-based company raised $12 million in total funding to date from Cargill Ventures, Focus Ventures, Foundation Capital, and Institutional Venture Partners. Completion of the acquisition by Thomson Reuters is subject to standard regulatory approvals.
