.~ Comprising structurally defined foam material or configuration
DEFINITION
Classification: 5/953
Comprising structurally defined foam material or configuration:
A collection of documents under art collection 948 disclosing the use of an expanded cellular substance having unconventional physical or chemical properties.
(1) Note. Since expanded cellular foams are conventional materials of construction for body supports, placing a document in this subclass requires some inherently unconventional chemical or physical property of the foam, or the foam must have been modified by the addition of other materials to exhibit an unconventional physical or chemical property.
(2) Note. Unusual foam configurations can include the use of chunks, chips, layers, blocks, or unusual shapes and sizes of conventional foams, or an unusual aggregation, such as layering of conventional foams.
