It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the self-climbing screed system as disclosed by Chen and include the screed comprising: a turntable configured to be positioned around the mast, the turntable being mountable to and dismountable from the mast; a screed boom having a proximal end and a distal end, the proximal end being connected to the turntable as disclosed by Sacken. When modified, the turntable as disclosed would be modified to be open and attached at a certain point around the mast/tower, furthermore, attaching the screed boom to the turn table allowing for a 360 rotation for ease of pouring concrete. As well as integrating and modifying the already attached latches to be flush with the frame of the turntable allowing mounting/dismounting. Doing so allowing for an easy of concrete pour regarding large projects in a 360-degree rotation range and further allowing ease of transportation between separate job sites. In general, it has been held that a mere change in shape of a component is within the level of ordinary skill in the art absent persuasive evidence that a particular configuration of the claimed shape is significant.
