The names of the milk tea shops need not be the same.

The products are exactly the same, but the trademarks are different, which does not necessarily constitute infringement. It also depends on whether the two trademarks are similar enough to easily cause confusion among the relevant public.

Bubble tea, also known as Boba milk tea, or bubble milk for short, is a tea drink popular in Taiwan. After adding powder balls to the milk tea, it becomes bubble milk tea. Pearl milk tea is a type of Taiwan's "bubble black tea" culture. Although it only adds tapioca rice balls to milk tea, it has become one of Taiwan's most representative drinks and snacks. Bubble tea is a fun drink that usually consists of black or oolong tea, milk or fruit flavor, sweetener and a chewy texture in Taiwanese cuisine called QQ (you might think of the 'bubbles' in bubble tea). Most often, QQ comes in the form of tapioca pearls. The name "bubble tea" originally came from the bubbles that form when the milk tea is shaken, rather than from the interesting pearls in the drink. This drink is known by many other names, including "bubble tea," "boba tea," and "tapioca tea."
