一、According to Article 27 of the TRIPS Agreement, patents shall be granted if inventions meet patentability requirements, including utility, novelty and inventive step (or non-obviousness). However, many WTO members, including the USA, Japan and Taiwan, provide the grace period system to grant patents for inventions even if they have been made available to the public before the date of filing of the patent application. Please elaborate the grace period system set forth in Article 22 of the Republic of China Patent Act.（30分）

二、Please translate the following extract from an opinion of the Supreme Court into English：（20分） 按發明專利權範圍，以申請專利範圍為準，於解釋申請專利範圍時， 並得審酌說明書及圖式。解釋申請專利範圍是以其中所載之文字為核 心，探究該發明所屬技術領域中具有通常知識者於申請專利時所認知 或瞭解該文字之字面意義。除非申請人在說明書中已賦予明確的定 義，若申請人無明顯意圖賦予該文字其他意義，該文字被推定為具有 通常知識者所認知或瞭解的通常習慣意義。

a. The maximum um axial load P that can be applied to the shaft. (15%)

b. The principal stresses es and the maximun shearing stress st a point an the outside surface of midway BC. (10%) 

(a) Wrie equations for the shear and the bending maorsent for any section of the beam in the interval CD. (10%)

(b) Draw complete shear and bending moment dingrams for the beam. (15%6)

Prablem 3 (25%) The stress-strain dingram for a bone is shown as the right figure snd can be described by the equstion, where g is in kPa. Determine the modulus of toughness and the a amount of elongation of a 200-mm-long region just before it fractures if failure occurs at σ =6873.52 kPa.

Problem 4 (25%) The bone sbown as the right figure can be modeled as a tube having an inner diameter of 9.5 mm and an outer G (MPa) dianneter of 32 mm. Dotermine the maximum um eiasti tic 16.10 static force P that can be applied to its center. r. Assume 8.75 the bone to be roller supported at its ends. The stress-strain diagran for the bone is shown as the figure below, and is the sanne in tension as in compression.
