Apple has revoked Monster’s MFi program membership, according to a report from The Wall Street Journal. Representatives from Monster reported the news, indicating that the move was in retaliation to Monster’s lawsuit against the now-Apple-owned Beats Electronics. Monster has been making licensed accessories under the MFi program since 2005, and many of its accessories have even been sold in Apple’s retail stores. David Tognotti, general counsel for Monster, stated that Apple’s chief litigation counsel advised him that their MFi agreement was being terminated as of May 5 due to their relationship with Apple no longer being “mutually beneficial” and that Monster’s lawsuit against Beats would “destroy the working relationship” between the two companies. Monster has reportedly paid Apple more than $12 million in licensing fees since 2008, and more than 20 percent of the company’s products are produced under the MFi program license. Under the terms of the agreement, Monster will still be able to sell its existing stock of Apple-licensed accessories until September, but will no longer be permitted to manufacture new MFi accessories.
