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.

The issue at hand is the shape and packaging of the sandwiches, with Smucker alleging that Trader Joe's product has a similar round shape and crimped edges, as well as similar packaging. Trader Joe's has countered that its sandwiches are not round, but rather shaped as "squircles" with rounded edges. The company has also addressed the packaging, but the details of its argument are part of the court filings.

Further information on the lawsuit and the arguments presented by both sides is available from the source.
