What are the patent rights for commodity inventions obtained by Nobel?

Liquid explosives, explosives and X-ray tubes Nobel is engaged in research work, not just explosives. Like his father Emmanuel, Nobel's rich imagination sometimes reaches a whimsical state. His research work covers a wide range of natural science fields, including electrochemistry, optics, mechanics, biology, physiology and medicine. Nobel has never forgotten an idea he inherited from his father in his early years, that is, using raw materials to make explosives to make leather substitutes. After many experiments, he obtained a temporary invention patent in this field. Later, Nobel planned to build a factory for artificial leather products. This plan did not come true for some reason, but the leather and lacquered cloth substitutes that appeared during World War II used his original inventions to varying degrees. Nobel also carried out improvement experiments on records, telephones, batteries and electric light accessories. He even put clay into a test tube and melted it by using the high temperature generated by explosives, trying to make artificial gem. His exploratory experimental work greatly inspired inventors who later had better equipment. Andre, a Swedish explorer, once sailed a balloon to explore the North Pole. 1896 after his first attempt failed, he sought support from Nobel. Nobel expressed warm congratulations on his exploration plan and promised to help him in his next flight. Then, Nobel said to the people present: "No matter whether Andre can fly to his destination or just fly halfway, this special achievement is a creative work in itself, which will produce new ideas and new changes. 189 1 year, Nobel cooperated with an inventor of the Swedish military department to develop a military rocket. Nobel's characteristic is always standing at the forefront of the times. When Nobel's assistant carefully read his catalogue of patented inventions, he could not help feeling that so many inventions actually came from one person's mind. The assistant wrote: In the eyes of serious technical experts and entrepreneurs, many of Nobel's ideas are just whimsy and whimsy. But don't forget that many ideas that modern technical experts think have actually been realized by Nobel and become the most important thing. It should also be remembered that some of his other ideas can be applied to various fields in the end. In his creative activities, his real talent is rich in ideas, just like the nature of production. Nobel himself once said, "if I have a thousand ideas a year, even if there is only one useful idea, I will be satisfied." "
