Technology area: Chemistry & Materials
1 pending office actions • 1 art units • 1 examiners • 0 of 1 (0%) have an AI response strategy ready
Virobuster International GmbH currently has 1 pending office action within the Chemistry & Materials technology area. This single action is assigned to 1 distinct examiner and 1 distinct art unit, representing a focused point of contact within the patent office. For a company operating in the technical fields of chemistry and materials, this concentration means that the immediate success of their patent prosecution rests on a singular interaction rather than a broad portfolio of diverse applications. The alignment of 1 examiner and 1 art unit suggests that the subject matter is specialized and has not yet branched into multiple technical classifications.
The specific examiner assigned to this case is TAI, XIUYU, who is also listed as the busiest examiner for the portfolio with 1 pending office action. Because there is only 1 pending action in total, this examiner handles the entirety of the company's current workload. This creates a scenario where the practitioner can focus resources on understanding the specific examination style and prior art preferences of TAI, XIUYU. The presence of only 1 distinct examiner and 1 distinct art unit simplifies the communication path but also focuses the success of the active filing on a single set of examiner expectations.
Difficulty is derived from the rejection statutes on the most recent pending office action. §101-driven and multi-statute cases are graded Hard; §112-only and obviousness-type double-patenting cases are graded Easy; everything else is Medium. "Unknown" means we have not yet parsed a statute for that office action.
