Analysis

SCHLEE IP INTERNATIONAL, P.C. reports 442 career applications, 5 pending office actions, and a Biotechnology & Pharmaceuticals focus. The application history accompanies a limited current workload in a field where claim definitions, biological support, and therapeutic or functional evidence can be central to examination.

The resolved allowance rate is 93.33%, and the average is 2.6 office actions per allowance. The first measure provides historical outcome context, while the second describes the examination effort associated with an allowance. Practitioners may use the pair when planning prosecution, while recognizing that they do not identify the grounds or technologies behind individual results.

File-level review should examine written description, enablement, prior art, and the evidentiary basis for claimed biological or therapeutic features. That review helps translate the profile's aggregate indicators into a defensible strategy for a particular application.
