Integrating basic research and technology into business is a critical factor in corporate competitive strategy. It has been proposed to describe problems in the research and development of companies, and the "Boost Gate (hereafter BG)" method as a method to overcome them. It is suggested that the use of this method leads to invigorated fundamental research activities within corporate R&D. Existing research on BG has provided certain details on the type of advice provided at each gate. Yet, these details have not provided methods for handling promising topics that still did not meet decision criteria, including whether to revert these topics or clear them to the next gate after advice is provided. Further, there are limited cases available for reference wherein BG has been implemented. This paper outlines the advising method for topics that do not meet a gate's decision criteria in BG. It also provides a reference for leveraging BG in corporate R&D by presenting an actual implementation case of that method.
