Rebirth of Northern Technology

Generally speaking, in the field of scientific research, a saying that everyone often says is to stand on the shoulders of giants.

Its implication is that future generations of scientists will step on the footsteps of their predecessors, groping forward generation after generation.

Hero Nakamura chose another path, that is, stepping on the heads of his predecessors!

However, in this world came a more fierce one!

Cheng Yongxing didn't just step on his shoulders and head, he was here to lift the table!

—————————

After a month of hard work in Fengtian, and with the help of an equipment factory, Cheng Yongxing has actually reached the forefront of science and technology in this world.

Even compared with Nakamura, his progress is at least one month ahead.

Judging from the blue LED timeline compiled by future generations, Nakamura should get his first gallium nitride crystal film next month, which is September 1990.

The achievement of this step, although not of great thesis value, but it has considerable patent value.

A large number of Yueya Chemical's patents are piled up here in the preparation of gallium nitride. These patents should have been applied for during this period or some time later.

Therefore, when Cheng Yongxing returned to Bingcheng, the first thing to do was to apply for a patent!

—————————

Patent application is also a university question.

The patent applications we often talk about are actually functional patents. For example, I modified something or invented something.

But there is another kind of patent, which is directed at other patents, which is a destructive patent. The purpose of its existence is to destroy the patents of others.

For example, you invented a bicycle pedal. So my patent is pedals of various colors. You have no product patents, but you can't use them.

—————————

There is also a patent, which is a protective patent. The purpose of this kind of patent is to protect the existence of the main patent. Because many patents can be bypassed.

For example, the core of the double blowing method is two airflows, one suppressed from top to bottom. So can I design a new structure and change it into three air streams, with two air streams from top to bottom?

Or blow it down at 45 degrees, can't it?

Let's not talk about whether these patents can be approved, but the idea is probably what it means.

Can this method be effectively prevented when applying for a patent?

For example, I do not apply for the double blowing method, but generally refers to any method of blowing from top to bottom, will it enter my patent category?

This method of expanding the scope of application, of course, will expand the scope of protection after it is approved, but there is a high possibility that it will be rejected!

Because of this patent application, it may cover the structure that has been published or the patent that has been applied for.

Under normal circumstances, when a patent application is rejected, the applicant will generally narrow the scope of the patent based on the given opinions, thereby increasing the pass rate.

But this creates a new risk, and the best time to apply for a patent is missed. Everyone is staring at this famous technological invention. There are even some people who are dedicated to staring at the newly published papers, and then try their luck to apply for their own patents.

Once the rejected situation occurs, someone else's patent may be passed. Or maybe because the paper was published first, the patent can no longer be applied for!

It takes a long time to reject or pass a patent. If it is not a success, the risk is extremely high.

The scope of the patent is too large to be approved. If the scope is too small, it is easy to leave loopholes.

Because there is too much talk about it, patent application has become a specialized subject. As long as it is a slightly larger technology company, it will raise a group of experts to guide engineers to apply for patents.

—————————

The auxiliary patent clusters formed around the core patents are called patent barriers.

Of course, this kind of patent cluster has two purposes. One is to prevent others from sneaking and bypass the main patent. This kind of patent itself may not be meaningful, it is just a garbage patent, but as mentioned above, once someone else’s patent is touched, the patent will become invalid.

For example, the inventor himself applied for a multi-air flow, multi-angle patent. If approved, there will naturally be an extra layer of protection. If it is rejected, it will not affect the approval of the main patent, and there will be no loss.

The other is monopoly. When a patent is granted, it is sold in bundles.

There are not many ordinary scientific and technological workers who can apply for patents correctly, especially in this era. And those who have experience to engage in patent barriers are even rarer!

This is not even an ordinary scientific researcher, even a company can handle it. Only those large patent firms have the ability to specialize in these things and play with this luxury.

A patent, especially an international patent, is not worth tens of thousands of dollars. If attorney fees are added, $50,000 is considered the average price.

Based on the 60 patent groups formed by Yueya around the blue LED, the cost of applying for a patent alone is more than three million US dollars. This does not include the attorney fees involved in various lawsuits that will be encountered in the future.

This kind of game is not a huge profit, and it is not worth hundreds of millions, so it is not worth playing like this.

Cheng Yongxing's patent level is only an entry level, he has only heard of such a luxury thing as patent barriers, but has never seen it.

—————————

Another reason for restricting patent applications is cost.

According to Yueya's approach, the total number of patents for the entire Blu-ray portfolio is at least 60. However, the total number of patent applications for the two project groups of the optical fiber laboratory and MEMS has not reached this number.

As long as Cheng Yongxing produces a two-digit patent application form, it will definitely cause an uproar.

I am afraid that this patent application model has not appeared in the history of Chinese science and technology.

The second is the cost itself. International patent applications are only recognized in U.S. dollars.

Regardless of the cost of the subsequent steps, it is only the registration fee for the first phase. After a few dozen, it will cost 100,000 US dollars. This number, in this era, is about the same as the astronomical number. At the current prices, it is enough to build another low-profile semiconductor laboratory.

The school will not pay the money anyway.

Because patents don’t just register.

Should I pay for the next steps?

Do not pay, then do things now. It's just taking money to get rid of water. If you pay, the follow-up cost will be multiplied by 20 times the existing cost!

3 million US dollars, calculated at the exchange rate of the black market, 30 million yuan! It is almost equal to the school's one-year education expenditure, and it is foreign exchange!

The application of international patents is also a novelty to the University of Technology. More than half a year, that is, because of the two joint laboratories, it is considered a start.

The blue LED project can get special approval and get valuable foreign exchange. This is already the result of special affairs.

Most scientific research projects, even if the inventor has an idea, apply for domestic patents. Even for later generations, not many schools are willing to subsidize international patent applications.

In this case, Cheng Yongxing can only make a low allocation plan and apply for a core patent. As for protection and barriers, he knew it, but he was powerless.

After a busy month of work, the result was just a few patent application forms.

And whether these patents can be approved is still unknown. Perhaps Yueya Chemical, where Nakamura is located, is already applying for the same process patent.

After working on patents, it is reasonable to continue to work on scientific research, continue to consolidate and occupy the leading scientific research position, but the laboratory has not been established yet.
