Appeal No. 2004-0415 Application No. 09/764,743 admittedly old shopping cart, wherein improvement is said to include the implementation of: [A] spring urged brake mechanism capable of selectively impinging against said rear wheels in order to provide a braking force; and [M]eans for releasing said impinging when two respective shopping carts are nested together. The dispositive question is, therefore, whether one of ordinary skill in the art would have been led to employ the above improvement in the old shopping cart. On this record, we answer this question in the affirmative. As is apparent from this record, the appellants do not dispute the examiner’s finding1 that: Trimble teaches a conventional shopping cart comprising front and rear wheels, a basket with an upper rim (Figure 1) and a spring (60) urged brake mechanism capable of selectively impinging against the rear wheels (Figure 1) in order to provide a braking force, and means for releasing said impinging when two respective shopping carts are nested (lines 18-21 of column 6). In other words, the appellants do not dispute that Trimble teaches the claimed improvement, i.e., the claimed spring urged brake mechanism and releasing means. See also Trimble, column 5, lines 10-62 and column 6, lines 7-25.
