A sponge cushion material is suitable for use as a carpet underlay. The sponge cushion has a cellular layer bonded to two nonwoven textile layers which can delaminate. The carpet is adhesively bonded to the cellular layer and one of the textile layers is adhesively bonded to a floor. The carpet can be easily removed by pulling it away from the floor so that the two textile layers delaminate and one of the textile layers remains bonded to the floor.

An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
