A lawsuit filed by J.M. Smucker against Trader Joe's will be allowed to proceed. Smucker claims that Trader Joe's frozen peanut butter and jelly sandwiches are too similar to its Uncrustables product. The lawsuit alleges that the shape and packaging of Trader Joe's sandwiches infringe on Smucker's trademark.

Trader Joe's has argued that its sandwiches are not round, but rather shaped as "squircles" with rounded edges. The company also disputes the similarity of its packaging to that of Uncrustables.

Further details on the lawsuit and the court's decision are available from the source. The case was filed in federal court in Ohio, where it will continue to move forward.
