Wartime Law on Industrial Property

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Wartime Law on Industrial Property (Kogyo Shoyuken Senji Ho) was a special law enacted by the Government of Japan in 1917, which declared that any patents owned by the nationals of countries in a state of war with Japan no longer had effect. The impact of this law was both immense and lasting, because a majority of drugs had been invented in Germany and this law meant that Japanese companies could produce them without worrying about patent infringement.
