A brief introduction to the book The Patents of the Poor.

The Patent Right of the Poor, one of the masterpieces of Dickens' short stories. During the Constitution Movement, John, an industrious and gentle old blacksmith, was persuaded to come to London, and he encountered all kinds of sad twists and turns in the process of applying for the invention patent right from the government. He stopped his work and spent more than six weeks. He had to deal with all kinds of people over and over again, from the high queen to the interior minister, judges, financial assistants, and so on. He went through 36 procedures and paid nearly 1 pounds (that was not a small number). Finally, the patent right was finally settled, but "it is only useful in the United Kingdom. If it is taken out of the United Kingdom, it will cost another 3 pounds."
