Hsu tells an anecdote: more than ten years ago, local inventor Huang Ying-chun devised an air-cushioned shoe. Unfortunately, due to the fact that at the time accessing relevant information was problematic, he did not scrutinize foreign patents and applied only for a domestic patent, with the result that this patent was later challenged and overturned by Nike.
徐義權舉例，十多年前國內發明人黃英俊就發明出氣墊鞋，可惜因當時資訊不方便，沒有進行國外專利的檢索而只申請國內專利，以至於後來專利權被耐吉 (NIKE) 撤銷。
