Antitrust claims over eBay’s accepted payments policy were allowed to stand this week in a class action against the company and its payments subsidiary PayPal.

The suit, filed in 2010, alleges eBay’s accepted payments policy has made PayPal the only viable payment method, and forces sellers to pay fees to both the marketplace and PayPal.

Earlier this year, the class narrowed its “tying claims” to focus on the continued modification of eBay’s payment policy, which locked out competitors including Google Checkout, according to the suit. eBay’s motion to dismiss the tying claims was denied on Tuesday.

The judge also denied the company’s motion to strike paragraphs about its acquisitions of PayPal and Verisign that “demonstrate the historical progression of the eBay/PayPal business empire,” according to a Courthouse News Service report.
