SEC. 101
Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.
美國專利法對Machine的定義是多個機構元件的組成與結構
此類發明案,"Apparatus"是一般建議用的名詞,可能比device或是其他用詞所能解釋的範圍還大,當然,應該還是看該專利的實際技術特徵,這裡是建議較好的命名方式
對解釋此類專利的Claim範圍時,或是考量新穎性、進步性的要件時,會考量所包含的元件與各元件間的連接關係,而其中各機構元件的運作或是產生的結果也都有"可能"列入考量,但是如果有"相同領域"公開的技術或是前案涵蓋該發明案的Claim的所有元件,即使產生的結果不同,實務上也難以獲准專利。
舉個例子:
美國專利第5,801,497號揭露一個power輸出裝置
這就是一個很典型的機構案,圖示中描述一個power output apparatus 10,其中元件有complex motor 30, stator 32, rotor 34, crankshaft 56, engine 50, rotor 36, drive shaft 22, first motor MG1, second motor MG2, driving circuit 92, three-phase coils 38等,而Claim除了放入這些必要元件外,需要描述各元件的連接關係。
Claim列舉如下:
1. A power output apparatus for outputting power to a drive shaft (先提到目的,多半並無需要), said power output apparatus comprising:
- an engine having an output shaft;
- a complex motor comprising a stator having multi-phase coils wound thereon, a first rotor connecting with said output shaft of said engine, and a second rotor connecting with said drive shaft, wherein said stator and said first rotor constitute a first motor that can carry out a regenerative operation and said stator and said second rotor constitute a second motor, at least either one of said first motor and said second motor being constructed as a non-synchronous motor;
- a motor-driving circuit for regulating an exciting electric current flown through said multi-phase coils wound on said stator of said complex motor, thereby driving said first motor and said second motor in said complex motor; and
- control means for driving and controlling said first motor and said second motor via said motor-driving circuit, so as to enable at least part of power output from said engine to be output to said drive shaft.
