Patent Term Adjustments (PTA) and Patent Term Extensions (PTE)

A review of the prosecution history for US Patent 6,963,505 indicates that no Patent Term Adjustments (PTA) or Patent Term Extensions (PTE) were granted.

PTE is a separate mechanism, typically used to restore patent term lost due to regulatory review of products like pharmaceuticals. As neither of these extensions apply, the patent's term is determined directly from its filing date.
