I have this little text here where I am not entirely sure how to understand the second sentence.


Does it mean that the companies rather see their ideas used by other companies when it means to avoid patent battle in the court?

I am also unsure if the correct answer is one or two as they seem quite similar in meaning.

Can someone help me with this text?



問題1 なぜ「ブラックボックス」化が広まりましたか。
1 特許を受け取り使用料より裁判費用のほうが高いからです。
2 裁判をしなければならなくなるからです。
3 技術が漏{も}れたり裁判の煩{わずら}わしさの恐れが生まれるからです。
4 せっかく得た技術が全部盗まれてしまうからです。

  • BTW What does it mean: "the companies rather see their ideas used by other companies when it means to avoid patent battle in the court"?

1 Answer 1


No, I don't think that's what the sentence is saying.


= (A) the profits received from other companies using the companies patents



= (B) and because of the outcome of technical skills passing on to other companies, there is a risk that their own company's technological level are becoming lower.


Comparing (A) and (B)


It is the case that companies are selecting the latter (B).

That's at least how I translate it.

I would have picked 4 myself but that's because I failed to read the first sentence at all. As naruto suggests 3 would be the correct answer since it lists both demerits.

(one of the most helpful hints for studying for the JLPT I learned was that for Japanese reading comprehensions you should never infer. [unlike the GRE which often asks the reader to infer])

    『「ほかの会社から特許の使用料をもらう利益」(=A)と、「技術がほかの会社に流れて結局は自分の会社の技術力が低くなる危険性」(=B)とを比べて、後者(=B)を選ぶ』ってことですよね・・・。「技術がほかの会社に流れて結局は自分の会社の技術力が低くなる危険性」とは、「risk of 自分の会社の技術力が低くなる as a result of 技術がほかの会社に流れる」
