In the first grade of elementary school, Edison was persuaded to withdraw from school because he was embarrassed by the teacher by publicly asking strange and tricky questions. (Is it illegal to dissuade elementary school students?) ）

Semi-illiterate and semi-scientifically illiterate Edison invented and created about a hundred kinds of inventions, including phonographs, film projectors, Edison mineral processors, automatic voting counters, improved telegraph machines, mimeograph machines, bamboo charcoal filament bulbs, lead-acid batteries, fuses, DC generators, etc.

There are more than a thousand patents for inventions under Edison's name.

Most of these invention patents belong to the collective research results of Edison's research team.

The reason why Edison spent a lot of money to feed a large number of researchers was to legally occupy the ownership of their invention patents.

According to the Patent Law, inventions made by employees of enterprises using the company's capital, technical materials and equipment are service inventions.

The right to apply for patents and the ownership of patents for service inventions belong to the enterprise.

Of course, if the business owner is willing, the ownership of these invention patents can also be jointly owned by the enterprise and the inventor.

The specific proportion of the division is negotiated by the business owner and the inventor, and in general, it is 50% each.

Of course, Edison could not easily split the ownership of patents with his subordinates, because patent ownership meant huge profits.

It was not easy for Edison to pay them a high salary.

In the United States in the 19th century, where there were mostly illiterate and semi-illiterate people, it was very rare for entrepreneurial capitalists who could pay attention to scientific research.

So these researchers can only work for Edison.

Although Edison was insatiably greedy for profit and righteousness, his and his scientific research team's great contribution to human civilization cannot be denied.
