After a few seconds of silence again, Li Rui, as a representative, also spoke again:

"I think rudder surface operation should be feasible, but the key is the lift of the wing, whether it can support continuous flight ......"

Zhu Jingyuan also nodded and said:

"Yes, the key is flying, and I hope that Qigong can test it as soon as possible, and the available aircraft can make a huge impact, which will benefit our ...... Ahem......"

Zhu Jingyuan almost said his true thoughts, but when the words came to his mouth, he suddenly reacted, and the relevant news had not been made public, so he forcibly stopped the conversation.

At this juncture when the peace talks began, if the Ming Dynasty could quickly build a working aircraft, it would certainly be very beneficial to the negotiations.

Although such early aircraft, like tanks, could hardly have a direct impact on the overall course of the war, the potential and deterrence of flying machines could not be ignored.

The enemy has it, and they don't, and it creates anxiety, mental stress, and makes them better at talking.

As for the role of the aircraft after it matures, this does not need to be specifically described by Zhu Jingyuan, and everyone can imagine that air-to-ground is absolutely suppressive.

Zhu Jingyuan looked at Zou Bingtai, the secretary of the Ministry of Industry, with a serious expression, hoping that the other party could understand:

"The Great Commonplace ......"

Zou Bingtai really understood, and told Li Rui very seriously:

"As soon as possible...... No, go test it right away. ”

Li Rui didn't want to chat with others, but now his colleagues in other departments of the Ministry of Industry are too busy, so he can only ask officials from the Ordnance Department and the Ship Department to come over to accompany the guests.

At this time, after receiving the order, Li Rui immediately stood up with the drawings drawn by Zhu Jingyuan, and bowed to Zhu Jingyuan's father and son and Zou Bingtai:

"Regardless of success or failure, thank Your Highness Jingyuan for the ideas provided, and the lower officials will test it."

Obviously, he felt that Zhu Jingyuan's idea could be tried, but his confidence was still not high, after all, he had failed too many times before.

After Li Rui left, Zou Bingtai, who was a little anxious, instinctively began to prepare again, brewing kind words to send off the guests.

As a result, Zhu Jingyuan took a sip of tea and immediately spoke again:

"Dasikong, I proposed a new airfoil of a flying machine to improve lift, and the scheme of controlling the flight attitude through the rudder surface, pulley, and steel wire, can I apply for a patent?"

The ironclad shield car can basically only be used for military purposes, and there are already civilian car patents, but the new invention of the aircraft can be used for civilian use.

The future of aircraft is unquestionable, and even in the most restrictive regions, air freight cannot be completely rejected.

Moreover, in the Ming Dynasty of this world, whether it is the mainland or the vassal states, there are too many places where ground transportation is inconvenient in this unusually vast space.

The overall population density may not be as good as that of the United States in the 21st century, and the civilian aircraft market will also be promising.

Therefore, the upper limit of the value of this patent is immeasurable.

Although the airplane is also a popular idea, the key realization scheme should be patentable.

It's a good thing to make money by allowing yourself to lie down.

Zou Bingtai was obviously stunned when he heard this question, and he instantly realized the value of these two patents, of course, provided that they could realize it.

If it can't be realized, even if it is patented, it is useless and cannot be sold.

So after thinking about it for a few seconds, Zou Bingtai replied after considering the language:

"Your Highness, if you only want to apply for patents for these two solutions, I can arrange for someone to do it now.

"Maybe no one thought about it before, but there should be no one who comes to apply for a patent.

"If you want to apply for a full, fixed-wing flying machine, you have to wait for the flight experiment to be successful."

Zhu Jingyuan was taken aback:

"Can I patent an aircraft? Something like an airplane that everyone knows, can I also apply for a patent? ”

Zou Bingtai nodded lightly and said:

"Yes, the concept of flying machines, although it was a few hundred years ago and is now widely known as a popular project, has still not been made.

"I can't say that there are no flying machines at all, some flying machines do fly, but only for a few seconds, and they are very unstable.

"We couldn't even tell if it was blown up for a few seconds like a kite, so we didn't get the application.

"In other words, no one has obtained the invention patent for flying machines."

Zhu Jingyuan instantly reacted that the principle of patent application in this era is obviously different from his previous life.

In this era, the "first-to-invent principle" means that whoever succeeds in creating a physical object first will be entitled to the patent for that thing.

The early inventions and creations were usually relatively simple, and they could be made with a little bit of money, and most of the functional effects were relatively intuitive.

However, with the development of science and technology, the difficulty of invention and creation is getting higher and higher, and many people can only put forward ideas and plans, and gradually cannot directly produce real objects.

If you go to someone to raise money for the production without getting a patent, you usually need to inform the investor of the idea, which is easy to plagiarize the idea.

Therefore, in later generations, many countries have adjusted their patent laws, from the early "first-to-invent principle" to the modern "first-to-file principle".

With a complete idea, you don't need to make a physical object, you can first apply for a patent, then go to the investment to raise money, and finally make a physical object to make a profit.

At the same time, it is no longer possible to apply for what is well known, and for the laws of nature that objectively exist.

The concept of aircraft has existed for hundreds of years, and as we all know, the application deadline has long passed.

In the future, if the aircraft is never made, the first successful person will not be able to apply for a patent for the aircraft itself, but can only apply for a patent for a "solution to realize the function of the aircraft".

But now, under the "first-to-invent principle", as long as no one has succeeded in doing it before, it can be applied.

I was able to get the invention patent for the airplane itself, just like the Wright brothers in another world.

The thing and the concept of the airplane will be its own!

Just thinking about this thing makes people uncontrollable and excited.

So Zhu Jingyuan nodded directly and said:

"Thank you for the reminder, then trouble Dasikong, first help apply for a patent for the airfoil and control method.

"If the flight experiment is successful, apply for a patent for the flying machine itself, and cite the first two patents."

This is a typical operation in later generations, where multiple patents are cross-referenced and bound to each other, and in the future, there are aircraft-related patents, which will also be tied to them.

In the future, we can also apply for patents for improved models and functions through continuous research and development, new technology innovation, and continuous application for improved models and functions on the concept of aircraft.

Achieve an indefinite extension of the de facto term of protection and build increasingly stringent patent barriers.

Of course, Zhu Jingyuan did this not to grab huge profits without a bottom line, but to take control into his own hands and prevent others from occupying patents and not working.

Historically, the Wright brothers patronized lawsuits against other American companies that did not pay royalties, but they themselves stopped further research and development.

As a result, the United States, which was the first to invent the airplane, was at a disadvantage in the early competition for airplanes for a long time.

Zhu Jingyuan will use the method of low-cost extensive authorization to attract members, so that as many manufacturers as possible can participate in research, production and promotion.

Establish and dominate the rules and standards of the entire aviation industry.

Of course, money has to be earned on its own.

With the patents of the aircraft itself, plus a lot of upgrade plans in your head, you can apply for a large number of improved patents, and you can make a lot of money by charging a few licensing fees.
