Technology area: Biotechnology & Pharmaceuticals
2 pending office actions • 2 art units • 2 examiners • 0 of 2 (0%) have an AI response strategy ready
Fettech LLC manages 2 pending office actions within the Biotechnology & Pharmaceuticals technology area. These actions are distributed across 2 distinct examiners and 2 distinct art units, showing a diversified prosecution effort relative to the portfolio size. The busiest examiner for the company is UNDERDAHL, THANE E, who is currently handling 1 pending office action. With 2 pending office actions, the company is engaging with multiple points of contact at the patent office.
The use of 2 distinct examiners and the current distribution across art units indicates that the Biotechnology & Pharmaceuticals filings are being reviewed in different specialized groups. This structure can be beneficial for risk management, as the company is not dependent on a single examiner's discretion. For a practitioner, the workload is split, with UNDERDAHL, THANE E managing 1 pending office action, while another examiner handles the remaining case. This arrangement requires monitoring separate timelines and sets of examiner behaviors. The presence of 2 distinct art units suggests that the company's innovations may span different sub-specialties within the broader technology area.
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.
