SAO PAULO, Aug 18 (Reuters) - A Brazilian subsidiary of

China's ride-hailing company DiDi Global sued Chinese

rival Keeta on Monday in a Sao Paulo court alleging trademark

infringement and unfair competition, according to court

documents seen by Reuters.

The lawsuit comes days after Keeta, which is entering the

Brazilian market, sued DiDi's Brazilian unit, 99, in Brazil,

alleging its food delivery app 99Food was trying to restrict

restaurants from working with more than two delivery platforms.

In Monday's lawsuit, 99 accused Keeta, owned by Chinese

delivery giant Meituan ( MPNGF ), of using colors, graphics and

font similar to 99's platform to "catapult its commercial

operations" in the Brazilian market.

"The numerous visual similarities ... induce undue

consumer confusion and the defendants seek to 'hitch a ride'" on

99's success, the lawsuit said, requesting the court order Keeta

to change its logo.

In a statement to Reuters, Keeta said its logo and

colors have been associated with Meituan ( MPNGF ) for over 14 years and

Keeta itself for the past three years. 99 declined to comment.
