Chudleigh’s is an apple farm and bakery based in Ontario, Canada, which sells baked goods to consumers and commercial entities. In the mid-1990s, Scott Chudleigh, an owner of the business, began developing a “single-serve, fully baked . . . apple pie” to sell to restaurants, to which it already distributed multi-serving apple pies. Mr. Chudleigh and his wife tested several possible shapes for the single-serve pies, settling on a round shape with six folds of pastry encircling the filling. Chudleigh’s registered a trademark for the six-fold pastry design, known as the Blossom Design, and the mark became incontestable in 2005.
