More than 30 Maryland cab companies are suing Uber, saying the company is hampering their ability to do business.
The lawsuit was filed Thursday in Baltimore Circuit Court, reported the Baltimore Sun. The lawsuit claims Uber's surge-pricing model is similar to price fixing, and the car service is creating an unfair marketplace.
Taxi companies have begun to fight Uber, a popular ride-sharing company that uses an app to summon rides. In D.C., taxis affiliated with the D.C. Taxi Operators Association closed down Pennsylvania Avenue last month in a protest against Uber that gridlocked traffic.
Virginia has barred Uber from operating in the state, and in San Francisco, the head of one of the oldest cab companies in the city has said that traditional taxis may not survive 18 months in the face of competition from Uber.
Maryland has become a new battlefront for the dispute, with cab companies lobbying against proposals to regulate Uber differently than cab companies.
The cab companies claim that services like Uber aren't regulated the same way that taxis are. Uber has countered that the ride-sharing model isn't a taxi service, and pointed to the consumer demand for the product.
Two of the companies that sued in Maryland -- Barwood Tax and Sun Cab -- are based in Montgomery County.
An Uber spokesperson says it's too early to comment on this lawsuit, but the company will defend itself if it has to.
