An anchor sheet subfloor that includes a laminate having an upper layer of relatively thin flexible rigid sheet material and a bottom layer of a relatively resilient cushioning material. The upper sheet layer can be formed of a plastic or polymer material. In one arrangement, the sheet can be cut and fit within the boundaries of a room and the sheet has sufficient rigidity and mass to remain without distortion or buckling within the room by free floating on the existing floor without substantial attachment to the floor. It can be possible for a sheet to be cut and fit on site to fit the contours of a room to form by itself or in combination wit other anchor sheets a free floating smooth subfloor on which can be overlaid decorative covering pieces.

Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
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.
