CYTIVA - Grogan, Tuccillo & Vanderleeden, LLP is a patent law firm that has filed 1633 career applications. The firm focuses on the Chemistry & Materials technology area. It maintains a resolved allowance rate pct of 92.87. This success is achieved with an avg office actions per allowance of 4.26. Currently, the firm has 8 pending office actions.

The avg office actions per allowance of 4.26 indicates a prosecution strategy involving several rounds of examiner interaction. In the Chemistry & Materials sector, this figure suggests the firm engages in multiple rounds of rejection and response to secure a grant. This approach is reflected in the 92.87 resolved allowance rate pct, showing that the firm succeeds in a large portion of its 1633 career applications. The 8 pending office actions suggest a specific phase in their current filing cycle. Practitioners can interpret these figures as a sign of a firm that reaches a final allowance even when the examination process is lengthy.
