"Why can a QR code do what a barcode can't do?"

Noah's question made Roy feel the goodness of elite talents, and he looked at each other from the bottom of his heart.

Roy had such an impression, not because of how well Noah asked this question, but because if ordinary people heard Roy's more detailed explanation just now, they would have nodded and applauded, and they would subconsciously think of asking why.

Not asking why is not because they know how it works, but because they don't want to show their timidity in front of professionals, it will appear ignorant.

This reminds Roy of a man named Wang Hongcheng in China in the 80s and 90s, and the older people are familiar with it. This almost semi-literate man, who only has a fourth-grade education level in primary school, pieced together to explain the water-to-oil technology he invented. At that time, the "Economic Daily", "People's Daily Overseas Edition" and other newspapers all published the so-called "China's fifth greatest invention" Wang Hongcheng's water-to-oil technology, and the Central Letters and Visits Office received letters from more than 200,000 experts, professors, and senior engineers across the country, requesting the central government to support this great invention.

In this process, there are constantly doubts, but there are always people who believe. It wasn't until a long time later that the deception was exposed and the farce stopped.

And Noah's frank ignorance and questioning of feasibility made Roy see the qualities of an elite.

Luo Yiyun smiled lightly: "In fact, this principle is very simple, the barcode stores information by lines of different widths and narrows, however, the dimension of line length is not actually used to store information, but, as a label attached to the item, it can't be only the length without the width, so the barcode is a waste of at least one dimension." ”

Roy draws vertical and horizontal stripes on the beach, showing the logic behind it at a glance.

If the barcode only has a horizontal dimension, it is a waste of the vertical dimension, and the criss-crossed QR code exponentially improves the capacity of information that can be expressed.

"This is indeed ......" The word great is not spoken, but Alyssa's exclamation is far beyond the literal meaning. She looked at Roy's childish face and felt a string in her heart be touched.

The cold and fierce Noah also applauded, and said forcefully and aggressively: "This idea is very good, I accepted it." ”

You took it?!

Roy and Alyssa were stunned - Nima, this is the villain!

Roy asked with an unkind face, "You don't think I'm stupid enough to not even apply for a patent, do you?"

"Of course not. Noah also picked up a branch and kept drawing figures on the beach, with triangles, circles, diamonds, and five-pointed stars...... He pointed to one of the patterns with a tree branch and said with a smile: "I can make hundreds of changes to each figure here, and I can make thousands of styles at will, without any problems, have you applied for a patent for these patterns?"

Alyssa shook her head helplessly, looking at Roy's eyes full of pity.

Roy took a deep breath, today is really Fake, he was put on a scene, he couldn't suppress his anger, and he wanted to rape and kill Noah's sister Ivy first.

Roy understands the common sense of patents, but he lacks experience in the means behind patent conflicts.

At this moment, Roy once again understood the deep meaning behind the phrase "knowledge is power". In the business world of high water depth, a person has no learning ability, and he can't even think of lines to anger his opponent.

So, what exactly does patent law protect?

Some people say that technology is protected, but technology is a very abstract thing, and any law must have a very clear and specific object and scope of application, so patent law cannot protect those abstract concepts.

Some people say that it is to protect the invention, so what is the invention?

Does inventing a new shape of a product count? If it didn't before, it does.

Does the invention of an important computer algorithm count?

It's hard to say, and it's usually not counted. As for having a new idea, a good idea, it is usually not protected by patents.

The main source of confusion in patent law is that there is a lot of flexibility in what the patent law protects and what it does not.

However, no matter how flexible it is, there are three very clear guidelines in the patent laws of various countries:

First, it protects the concrete, not the abstract.

For example, if you want to apply for a patent for a hexagonal QR code, this is not possible because the hexagonal shape is still too abstract, however, you can apply for a patent for a specific specific hexagonal QR code shape.

Second, patents do not protect ideas, only processes.

For example, I thought that I could use QR codes to solve the problem of complex inventory retrieval, which is not patentable in itself, but if I think of a process to make this idea come to fruition using my process, then my implementation method can be legally protected.

Therefore, if Noah also made a QR code, as long as he did not copy Roy's implementation process, there would be no infringement. In the IT field, a new algorithm cannot be patented, but the process of implementing such an algorithm in a special way can be patented.

Third, patents protect man-made things, not natural things, even if no one has discovered it before, and you have found it.

For example, there is salicylic acid in the willow bark, and the willow bark can be boiled and drunk to reduce the fever, which is a natural thing, no matter who finds it, you can't just allow yourself to boil the willow bark to drink, and others are not allowed to sell the willow bark to make money. However, if salicylic acid is made into acetylsalicylic acid (the active ingredient of aspirin) and becomes a drug, it can be protected by a patent.

Roy secretly analyzed for a long time, and he was forced to threaten directly: "Are you ready for a protracted lawsuit?"

Noah pretended to be surprised and shook his head: "No, no, no, of course not, we are all businessmen, and we will not do a loss-making business." ”

Roy wondered, "Then you still ......"

"-Mr. Roy, I think you have misunderstood, we each do our own market, why do we need to go to court? You must also know that those insatiable lawyers are raised with gold, and if we want to start a lawsuit, the profits we make are not enough for the legal costs, what do you say?"

"What you say may have a point, but this is a just battle, and I will not back down and will continue to fight until you are ruined. Roy said firmly.

Noah shook his head in disappointment: "I didn't expect you to be so rash instead of seriously estimating the cost of the conflict, to be honest, I'm quite disappointed." But, even then, the winner in the end won't be you. What's more, your company's investors won't sit idly by and watch your foolishness of losing both. ”

Roy sneered: "Alyssa is my investor, as long as I announce public financing now, there will be a large amount of money flowing into the company, and I can play as long as the lawsuit is." Right, Elisa?"

Alyssa was silent for a few seconds, and only after a few seconds did she persuade softly: "Roy, maybe you should give yourself some time to seriously consider this issue in private, and you have to remember that rational entrepreneurs can go to the end." ”

Roy gasped, feeling his heart stabbed like a knife stirring an axe, and it hurt to the heart. Although he is rarely emotional and understands Elisa's rational behavior, this "betrayal" pain is still unacceptable.

Could it be that no matter whether the truth is right or wrong, and which side justice is on, you have already lost?!

No, I still have a few killer features, and the show has just begun......
