A lawsuit over frozen peanut butter and jelly sandwiches can proceed, a federal judge has ruled. J.M. Smucker claims that Trader Joe's frozen sandwiches are too similar to its Uncrustables. The lawsuit alleges that Trader Joe's committed a trademark violation with its packaging and sandwich design.

Trader Joe's has argued that its sandwiches are not round, but rather shaped as "squircles" with rounded edges. The company also addressed the crimped design of its sandwiches in court filings.

Further details about the lawsuit and the judge's ruling are available from the source. The case was filed in federal court in Ohio, where Smucker initially sued Trader Joe's last fall.
