工業設計功能的發揮是創新發明的重要環節，本文主要目的是從工業設計技術構思的特徵，論述運用專利制度保護工業設計成果的適當形式。首先討論工業設計與創新發明的關係，並比較工業設計領域與專利領域對於工業設計定義與成果的差異，據此檢討我國現行專利制度與實務對於工業設計成果保護的缺失。接者，提出以手段功能用語為撰寫形式的適當性，包括論述該形式的適用時機與撰寫方式，並以實際的案例討論該形式對於保護效果的改進。最後提出以「手段功能用語」的撰寫方式，在專利請求項中尋求較佳的保護，以表達本研究之研究結果：工業設計之結果，尤其是涉及功能重組的創作發明，以手段功能用語之請求項更適合保護創作的價值。

The unleashing of industrial design utilization is an important part of innovations and inventions. The main purpose of this paper is to discuss the appropriate form of using the patent system to protect industrial design results from the characteristics of industrial design. Firstly, this article discussed the relationship between industrial design and innovation/invention, and then compared the differences definition and outcome between the discipline of industrial design and patent. Based on this review, the defects of protection industrial design results by our current patent system and practices are pointed out. And then, the author proposed the appropriateness of the using ＂means plus function＂ language as a form of drafting claims, including the discussion of the appropriate situation and writing method of that. It followed by discussing the improvement of the protection effect in practical terms. We expected to find out how the patent system could appropriately protect the results of industrial design products and strengthens ownership of the owners.
