An attorney's work product is absolutely privileged, and is not obtainable. The privilege extends only to documents prepared by counsel acting as such, and to materials uniquely the product of a lawyer's learning and professional skills, such as those reflecting the attorney's legal research, analysis, conclusions, legal theory, or strategy.
