Abstract
This installment of the semi-regular column on patent law presents part two of a case study of an electrochemical cell invention. The case study continues with the description of numerous "events" during the prosecution of the original patent application as well as three additional patent applications. Specifically, we describe a restriction/election requirement by the patent examiner leading to divisional patent applications. In addition, on-going research led to new embodiments of the original invention. The case study illustrates other prosecution events including non-final and final rejections, affidavits, requests for continued examination and examiner interviews. The intent of the authors is that the subject case study will enable electrochemical scientists, engineers, and technologists to better understand the invention to patent application process.
