4D Medicine Limited (T/A 4D Biomaterials) operates a company patent portfolio in the Medical Devices & Mechanical Engineering technology area. Currently, the organization has 1 pending office action. This single action is assigned to 1 distinct examiner, ensuring that the company's current legal efforts are concentrated on one specific set of claims. The prosecution is further localized within 1 distinct art unit.
ALEMAN, SARAH WEBB is the busiest examiner for this portfolio, currently overseeing 1 busiest examiner pending office action. Since the total count of pending actions is 1, this examiner is the only USPTO official with an active role in the company's current applications. This creates a direct and singular line of communication between the applicant and the patent office.
Practitioners should recognize that with 1 distinct examiner and 1 distinct art unit, there is no opportunity to compare different examination styles within the current portfolio. The progress of the 1 pending office action will be entirely subject to the interpretations and requirements of ALEMAN, SARAH WEBB. This focused structure requires a precise response strategy tailored to the specific standards of the single art unit involved in the Medical Devices & Mechanical Engineering field.
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.
