Roy is having a hard time right now, very sad to be exact, it's a feeling of falling out of love again. It was also the first time that he felt that Alyssa was so unlovable, and he doubted the rational portrayal of his future wife.

No matter how it ends, I have already written down these feuds.

Roy hid his weakness and irritability in his heart, straightened his back, looked at Noah, and said calmly: "You came all the way to make me have a longer memory? ”

Noah also put away his arrogance and conceit, and his expression became serious, "That's not the case, I'm here to cooperate with you." ”

"Cooperation?" Roy felt funny, just now Noah was aggressive to steal other people's results, and now he suddenly said that he wanted to cooperate, looking at his square look, he didn't expect to be a drama spirit, and he couldn't stop when the performance started.

"You may not believe it, but that's exactly what I came for. ”

"Do you want to cooperate in the development of the QR code market?" Roy asked calmly, now he has at least three hole cards in his hand, each of which can make the other party steal chickens and rice, so there is nothing to be angry about. Business model imitation, learning, learning is the norm, if you encounter this kind of trivial things, you will be indignant, complaining, that is definitely a failed entrepreneur, he has not yet adapted to the law of business warfare, in the big wave of entrepreneurship just play cannon fodder.

"It can be a QR code or something else, I have management experience, you have innovative ideas, we can work together perfectly. Noah invited earnestly.

Insiders often say that awesome entrepreneurs are all actors. This is not an exaggeration at all when applied to Noah.

The other party's combination of punches came over, and Roy couldn't tell which sentence was true and which was false, or he was in a trance and had a delusion.

"I beg you to see it, but I refuse. Roy continued, "Who knows if you're a spy on the enemy? Honestly, Mr. Fielding, I think you'd be better suited to go to Hollywood, which is really the place where you can make a big difference." ”

"It's not funny. Mr. Fan, I'm serious. ”

"Your seriousness didn't let me see sincerity, I can't be honest, what tacit cooperation can we talk about?"

"You're still too young. Noah sighed: "I admit that you have a sharp business vision, but you are too ambitious, you know, an excellent team can be in business, and there is no tomorrow for a lone hero." ”

"I never wanted to be in power, to be arbitrary. On the contrary, you communicate with others in such a high-minded and cooperative attitude, without a little self-knowledge, don't you think it's naïve?"

"I just want to prove that I have what it takes to match you. Noah mused, "I can cause trouble for you, share the profits, and I can also help your company to glory." ”

The corners of Roy's mouth rose, and he smiled lightly: "Although you are very annoying in this way, I still kindly remind you that the trouble you imagine can cause me will only be an itch in the boots in real practice, adding some fun to my company." Even if I don't choose to solve the problem by litigation, you still can't compete with me. The world of QR codes is far beyond your imagination. ”

This Roy is not a red-mouthed and white-toothed empty city plan, and that's what it is. On the surface, QR codes only add one dimension to barcodes, but in fact, there are many hidden mysteries.

On the 4 corners of the QR code, except for the lower right corner, there is a big eye-like frame in the other 3 triangles, which will tell the lens where the QR code is and which way the direction is facing. In fact, there are 22 small eyes hidden in the QR code picture horizontally and vertically, which are combined with 3 large eyes to adjust the graphic distortion.

All of these eyes work with Reed-Soloman's error correction code, and the machine can recognize even if the QR code is damaged or scribbled. (Appendix 1)

In reality, there are four levels of QR code error correction, 7%, 15%, 25%, and 30%, which means that up to 30% of the area is blocked without affecting decoding.

There are many more technical details like this in the QR code, and the high-quality experience brought by these aspects can make this product stand out from the competition in the market.

Technology is a little bit of an iteration, not an overnight process. Most of the problems are only discovered by engineers under the test of the market.

For example, when Apple first made smart phones, it just wanted to make the screen bigger, but the screen was bigger, and the place where the buttons were smaller; after thinking of a lot of methods, it began to try to use the touch screen, so that each mobile phone had a keypen......

In this way, the technical details are iteratively created layer by layer, and it is not the perfect creation of a genius in an instant, and the final version is directly developed.

Therefore, in the area of QR codes, when the products and technologies of competitors are polished and iterated little by little, and finally comparable to Roy products, the times do not know what will become of the times.

If Roy is a little more ruthless, sees that the timing is not right, and directly makes the QR code technology free and open-source, and adopts value-added marketing methods, then the competitors will definitely go bankrupt and can't find a place to cry.

Of course, this is just a strategy to disgust the opponent, and if the competition is not fierce to that extent, as a rational businessman, he will not lose both.

Noah's eyes wandered: "Are you so confident?"

"Hehe, if you are an engineer, you will know that there are new scientific and technological achievements in the world every day, but there are very few who have the ability to convert them into commercial use. You can't imagine the algorithm contained in this small picture, if you underestimate this ordinary QR code, you may suffer a big loss. ”

Noah hesitated for two seconds, and the sudden reversal of the situation made him hesitate, he thought for a while and said, "Maybe technically I am a layman, but in the study of patent law, I can win the blow." You may not know that when you invent a patent, you have to protect the process of realization very completely, of course, it is not enough to support technical barriers through only one patent, but through a series of patents. ”

"A series of patents?" Roy was very interested, and to be honest, patents were indeed his weakness.

"That's right, we must not only protect the realization method of a process, but also protect all possible realization processes, exhaust all roads, block all the simple implementation roads, and form a long, dense, and high patent Great Wall! Whoever wants to pass through will either leave the money to buy the road, or hit his head and bleed!"

Roy listened indistinctly, which reminded him of a well-known case in mobile communications.

CDMA is a method of communication, and its own patent has long expired in the era of mobile communication, and theoretically anyone can use it.

However, how to turn the 3G wireless communication standard CDMA into a process that can be implemented on mobile communications, this is the invention of Qualcomm. Qualcomm has been very clever in patenting all the simple implementation paths.

China did not want to pay royalties to Qualcomm at the time, so it wanted to devise an implementation process TD-SCDMA that bypassed Qualcomm's patents. However, when it was realized, it was found that this road had to be detoured so far that the 3G era had passed, and TD-SCDMA in China had not yet been popularized.

At this time, Roy actually has a real patent hidden danger to be solved, that is, this two-dimensional code technology patent, in fact, has been registered, the time is in 1994, the patent is registered in RIBEN, the registered company name is Denso Corporation, and this company is the largest spare parts supplier of Toyota Motor Corporation.

Roy felt that Noah's profession was his opportunity. He asked tentatively, "If we cooperate, how many shares are you going to take?"

[PS] Appendix 1: RS codes, also known as Reed-solomon codes, are a kind of forward error-correcting channel codes, which are valid for polynomials generated by correcting oversampled data. When the receiver receives enough points correctly, it can restore the original polynomial, even if many points on the received polynomial are distorted by noise.
