The online auction-comparison company Bidder’s Edge responded Feb. 10 to eBay’s December lawsuit against the company by asserting counterclaims that accuse eBay of “monopolization and attempted monopolization under the Sherman Act, unfair competition and interference with contractual relations” (eBay Inc. v. Bidder’s Edge, N.D. Calif., No. 0-99 21200, filed 2/10/99).

The response, along with reports that eBay is being investigated by the Department of Justice for possible antitrust violations, has called into question eBay’s recent strategy of attempting to control who can access and use its online auction information.
