This study analyzed the domestic patent trends of brassiere to provide fundamental data for promising technology. Relevant patents were searched by inputting the key words of “brassiere” and IPC code “A41C” on patent information search service of KIPRIS. A search for bras patents from 1985 to 2019 revealed 533 registered applications out of the total 744 listed. The IPC code with the highest portion (40%) was A41C3/00 (brassiere), followed by A41C3/14 (forming inserts, 21.6%), and A41C3/12 (component parts, 13.3%). To arrange the guidelines of the content of brassiere patents, we carried out a qualitative technology analysis on 744 patents, to extract 850 technology cases applied in patents. From the technological features of each case, main categories were classified into two parts (function and structure) and function was divided into 7 sub-categories that included physiological comfort, physical comfort, utility, healthcare, appearance, and economic value. As for the structure, cup showed the highest portion (37.9%), followed by pad (16.5%), and wings (13.2%). From the aspect of function, appearance showed the highest portion (30.8%), followed by usability (22.2%), physiological comfort (14.6%), physical comfort (14.6%), economic value (10.7%), and health care (7.4%).
