DuPont is really helpless, they are now also engaged in synthetic fibers, and even have produced some results, but these results are too far from nylon, and even so, they are only in the laboratory, and there is still a long way to go from industrial production.

The appearance of nylon can be said to have hit them with a slap in the face, and they also thought about blocking Yang Feng's patent application through the influence of the DuPont family, but as Yang Feng said, even if the United States does not give him a patent, but European countries will compete to give it to him, if the production right of nylon falls into their hands, it will be a fatal blow to DuPont, so they have to get Yang Feng's patent anyway, which is already related to the future of DuPont.

After some bargaining between the two parties, 25 percent of the royalties were finally determined, but DuPont had one more condition: Yang Feng could no longer license patents to other companies, and Yanhuang Labs had to provide technical support for DuPont's production.

"We definitely can't come out, the scientists in the Yanhuang Laboratory are very busy and don't have time to help you with production, but I will provide you with a complete set of production process information, and I will provide you with technical advice at any time in the future." Yang Feng said.

However, he also put forward a condition, that is, the market division of the two sides, Yang Feng's nylon products will not enter the American market, and DuPont's nylon products will not enter the Asian market, as for the European market, it depends on everyone's ability, but the price must be the same.

As for Yang Feng's car patents, except for radial tires, all the others were sold to General Motors at a price of two million US dollars, but because GM's financial situation is relatively tight, one and a half million of them are GM's shares, although Yang Feng is quite dissatisfied with this, but considering that GM's current stock price is only one dollar, he reluctantly accepted it.

However, he added another article that in the future, Chinese cars produced in China can use these patents for free, and GM has no opinion on this, and when the Chinese's cars have the ability to threaten them, twenty years have passed.

Soon after getting DuPont, Pfizer also agreed to Yang Feng's conditions, but there was also a condition, if Yang Feng's Tianyi Shenshui could be mass-produced in the future, then it must also be handed over to the joint venture pharmaceutical factory, otherwise they only agreed to give Yang Feng 30% of the shares, Yang Feng doesn't care about this, anyway, whether penicillin or streptomycin, must rely on Pfizer's fermentation process, and other pharmaceutical companies really can't play Pfizer in this regard.

Next is Kodak, they booked the patent for the Instant camera from Yang Feng at a price of 500,000 US dollars, and it doesn't matter to Yang Feng what they do after they buy it back.

The patent for radial tires was granted to Michelin by Yang Feng, and he originally wanted to sell them for 2 million, but Michelin did not have a bottom on this new technology, so it was changed to patent authorization, and the patent fee for each tire was 10%.

Basically, Yang Feng disclosed one item, and there would be American companies immediately coming to the door, or buying, or authorizing, and booking in various ways, with the urging of these people in the back, the US National Patent Office simply issued Yang Feng all the patent certificates he applied for a month and a half later, and Yang Feng's patent serialization was far from over.

In just one and a half months, Yang Fengguang received more than 10 million US dollars, and about 10 million US industrial giants, including General Motors and GE, sold the patents for tape recorders and rice cookers to GE, on the same condition that Chinese were exempt from patent fees when they were produced in China.

After having the money, he did not hesitate at all, and immediately took out two million dollars to buy silver, although he really wanted to buy silver in the American market, but this would immediately raise the price of silver, so he was ready to disperse to Europe, Japan and China to buy separately, especially those foreign banks in Japan and China, these guys have huge silver dollars in their hands, rather than let them smuggle into the United States after the introduction of the silver bill to make money, it is better to make this money for themselves.

His next new invention was polyethylene, and he was lucky, although he filed an application in the UK later than the Bnemen company, but he filed it earlier than the Bnemen company in the United States, so the U.S. Patent Office did not hesitate to issue him a patent certificate, and the British side did not know the result, but even if they gave the patent to the Bnemen company, it didn't matter, and several other countries in Europe would definitely be happy to add some blockage to them, because if the Bnemen company got the patent, they would not have a chance, On the contrary, give the patent to Yang Feng, then they all still have a chance.

The key is that Yang Feng submitted at the same time, as well as two different ways of high pressure and low pressure polyethylene synthesis process patents, that is to say, when the company held his British patent for polyethylene and shrank at home to study how to industrialize production, other countries could already open factories.

However, at this point, Yang Feng behaved quite noblely.

"This, the contemptible people did not expect such a situation to happen, if I had known that the company was ready to file a patent application, maybe I would have given up, and now that such a thing happened, I am also very uneasy.

In this way, in the name of Yanhuang Laboratory, I am entrusting your radio station to issue a statement, any enterprise that thinks it has production capacity can come to me to apply, if I think he does have this ability, then he can get the right to produce polyethylene, and only need to pay a patent fee of one percent of the selling price per ton, and I can also provide them with a full set of technical information, as well as follow-up technical consultation. Yang Feng said to the British BBC reporter who came to interview him.

"Is it possible for companies in any country?" This very coquettish mature woman said.

"Yes, any company in any country, including Japan, or even the Soviet Union." Yang Feng said solemnly.

The production of a ton of polyethylene needs to consume ten tons of crude oil, the flood of this kind of thing, will intensify the competition for crude oil to a greater extent, especially in countries like Japan without oil fields, and the downstream products of polyethylene are labor-intensive industries, the most suitable country is a large population, but the technology is relatively backward, and diligent and capable Japan.

China can't do it, and countries that fight every day are not suitable for this.

After a while, let's get the polypropylene out and let the white pollution come more violently! Make the scramble for oil bloodier! There will be no oil in China anyway.

No, I have to find an opportunity to plug Li Siguang's mouth quickly, and the other one seems to be Pan Zhongxiang, right? We must not let them study the fallacies and heresies that China has oil, so how can China have oil? How can China have oil? Oil-poor countries, real oil-poor countries, poorer than Japan!

Of course, Yang Feng's various inventions are not all popular, his little jeep was smashed in his hands, the Great Depression caused the United States to plummet by two-thirds of automobile production, countless small car factories went bankrupt, except for the later three, there are few left, in this case, it is obvious that no one has the courage to try such a car that is unreliable no matter how it looks, poor comfort, ugly appearance, and this kind of open roof is also outdated, driving such a car is obviously not favored by the girls.

This made Yang Feng quite depressed.

Nima, no one made Lao Tzu himself, this goods immediately found a bankrupt car factory, and then bought all the assets from the bank, recruited a group of workers, and brought the original boss back as a manager, a salary of three thousand dollars a year plus ten percent of the profit, and then handed everything over to him, Jinyuan Company was responsible for financial management, and soon a company named after an Indian tribe, the Cherokee Automobile Company was officially established in Detroit.

The first car launched by the Cherokee is Yang Feng's little jeep, because the prototype car can't come out for a while, it's still his one for advertising, but the outside adds a semi-metal and half-canvas roof that can be installed by himself, Yang Feng doesn't care how many cars he can sell in the United States, and after a while get a group of workers from China as apprentices, and see if it is not popular in the United States, it will be directly dismantled back to China with the machine, if it is popular in the United States, it is better, and it is good to stay here and continue to make money from Americans.

For this reason, he also personally went out and took a set of advertising photos, dressed in a western cowboy outfit, holding a finger-thick Havana cigar in his mouth, carrying two Colt revolches on his waist, standing on the endless wilderness, with an open-top jeep parked next to him, a small crop top on the upper body, and a pair of denim hot pants on the lower body.

Speaking of this chick, although she is now standard to be raised by Yang Feng, but when she thinks that she has just turned fifteen years old, Yang Feng can only struggle between birds and beasts, but with bikini advertising, she actually became a little popular, and now when she is idle, she follows Yang Feng as a vase, wears fashionable clothes to attend a prom dinner or something, and occasionally is invited to dance on Broadway.

As soon as he mentioned the movie, Yang Feng remembered that he still had an important thing to do, just at this time his patent serialization had been completed, so there was nothing on it in the last issue, only a row of big words: At eight o'clock tonight, Times Square, New York, the last invention of Yanhuang Laboratory.

That night, New Yorkers, who had been seduced by Yang Feng for more than three months, began to gather from various streets to Times Square, and even those homeless people looking for food in the garbage cans were much more than before, only to find that a unique screen was set up in the middle of the square, not almost a square in a movie theater, but an elongated rectangle.

"What you are about to see now is a new movie-watching experience, the latest widescreen movie launched by Yanhuang Lab!" Yang Feng, who was dressed in a Chinese collar at eight o'clock, shouted loudly into the microphone in the eyes of everyone.

Then in the background of the blooming flowers, a never-before-seen movie on the screen began.
