Premium Invalidity / Validity Search

In addition to our Standard Invalidity Search, Cardinal’s Premium Invalidity Search includes a dedicated patent literature searcher(s), a dedicated non-patent literature searcher(s), a library scientist(s) and a technical expert(s).

All of Cardinal’s project managers are patent attorneys* who will review the prosecution history (when available), claims, and the specification. Our Premium Invalidity Search Reports also include claim mapping as a standard feature.
