Reaction Engines Limited has 2 pending office actions in the Medical Devices & Mechanical Engineering technology area. These actions are handled by 2 distinct examiners within 1 distinct art unit, indicating a high degree of technical focus in the current prosecution. The presence of 1 distinct art unit suggests that the company's active filings are being reviewed under a unified set of technical guidelines, which can help in developing a cohesive strategy for the 2 pending office actions. This concentration within 1 distinct art unit may allow for more consistent application of technical standards across the portfolio.
JON SCHERMERHORN is the busiest examiner, overseeing 1 pending office action. This represents 1 of the 2 pending office actions currently on record for the company. Although there are 2 distinct examiners involved, the fact that they operate within the same art unit may lead to more predictable outcomes. The company can leverage its experience within this 1 distinct art unit to better anticipate the types of rejections or requirements that might arise across its Medical Devices & Mechanical Engineering portfolio, even as it addresses the individual feedback from the 2 distinct examiners.
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.
