Miromatrix Medical Inc. maintains 6 pending office actions in the Biotechnology & Pharmaceuticals technology area. These actions are spread across 6 distinct art units, showing a diverse range of technical classifications for their biological and pharmaceutical filings. The portfolio is being reviewed by 6 distinct examiners, with each examiner handling exactly one action. This distribution indicates that no single examiner or art unit currently dominates the company's pending patent prosecution, requiring a broad strategy across multiple USPTO divisions.
GU, QINHUA is the busiest examiner with 1 pending action. This highlights the lack of concentration in the portfolio, as even the most active examiner for this company only manages a single case. For a practitioner, this means that the prosecution of these 6 pending office actions will likely proceed independently of one another. The involvement of 6 distinct art units further suggests that the company's innovations touch on several different specialized fields within biotechnology. This variety requires the legal team to be prepared for different examination styles and technical standards across the various art units. The current data reflects a decentralized prosecution environment where each application is subject to a unique set of examiner expectations.
Based on the USPTO statutory response window for each pending office action. 1 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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.
| Bucket | Cases |
|---|---|
| §103 only | 1 (20%) |
