In accordance with the Enforcement Rules of the R.O.C. Patent Act, the _____ shall mean the technical feature(s) which define(s) a contribution which each of the claimed inventions, considered as a whole, makes over the prior art.

專利法施行細則第27條第2項規定：special technical features（特別技術特徵）指申請專利之發明整體對先前技術有所貢獻之技術特徵，與題幹「technical feature(s) which define(s) a contribution which each of the claimed inventions, considered as a whole, makes over the prior art」逐字相符，為唯一正確選項。
