Guiyu Chang currently manages a focused patent portfolio within the Transportation, E-Commerce & Mechanical Systems technology area. The portfolio features 1 pending office action, which represents the current active prosecution for this entity. This single matter is assigned to 1 distinct examiner, DEMUREN, BABAJIDE A, who is responsible for evaluating the technical claims. The prosecution is situated within a distinct art unit, reflecting a specific technical focus for the pending application.
The busiest examiner, DEMUREN, BABAJIDE A, is currently overseeing the 1 pending office action. This creates a concentrated prosecution environment where the outcome of the company's current patent efforts relies on the review of a single individual. For practitioners, this means that the prosecution strategy must be specifically tailored to the feedback and requirements of this one examiner. The lack of distribution across multiple examiners or art units suggests a singular and direct path through the examination process, requiring a focused approach to address the specific concerns raised within the transportation and mechanical systems sector.
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.
