Analysis

Sakata Seed Corporation has 6 pending office actions in the Biotechnology & Pharmaceuticals technology area. These actions are handled by 5 distinct examiners across 2 distinct art units. This concentration in only 2 art units suggests that the company's patent applications are focused on a narrow range of technical subject matter within the biotech sector. The high number of actions relative to the number of art units indicates a dense prosecution environment.

ZHONG, WAYNESHAOBIN is the busiest examiner, with 2 pending office actions. The remaining pending actions are distributed among the other distinct examiners. Because 6 pending actions are being reviewed in only 2 distinct art units, there is a high density of applications per specialized group. This concentration may allow for more consistent prosecution strategies within those 2 specialized groups, even though 5 different examiners are involved. Practitioners should focus on the standards of these 2 distinct art units while managing the preferences of the 5 distinct examiners.
