The owners of 462 Boston medallion cabs yesterday sued Uber for what they say are the profits Uber cost them through unfair competition over a five-year period.

The suit comes days after a federal judge dismissed a lawsuit by an association of Boston medallion owners against the state's new regulations that allow Uber, Lyft and other "transportation network companies" to operate, and a month after the judge dismissed the owners' suit against the city of Boston over the way it did or didn't regulate the companies.

The latest suit, filed yesterday in US District Court in Boston, names only Uber - and is limited to damages for the period between 2011, when Uber entered the Boston market and Aug. 4 of last year - the day before Gov. Baker signed a law removing Uber and similar companies from local control.

The suit alleges that by evading city taxi regulations - which set minimum standards for everything from the condition of cars and insurance to a requirement to serve people with disabilities - Uber put the medallion owners at an illegal disadvantage.
