  Patent, this was a term Lin Hong had never heard of before.

  He first knew that what he did could be patented, and later if someone else made the same thing, he could restrict the other party from producing it or collect patent fees.

  When he heard his mother introduce patents, he thought a lot in an instant.

  What is the role of patents? Is it to encourage people to invent and innovate, or to set up barriers and restrict everyone from inventing?

  He is still unclear about this issue for the time being. He knows too little, which has brought great obstacles to his thinking.

  This time, he felt that his vision was too narrow. In addition to the content of radio and computer, other things seemed to be worth learning about as well.

  Cook found that Lin Hong was not very enthusiastic about this matter, so he shifted his attention to Feng Wen and tried hard to persuade her to apply for a patent for this thing and start entrusting manufacturers to produce it as soon as possible. He repeatedly emphasized that this is a very good product, absolutely with a huge market. Moreover, he also promised that the patent application in the United States can be entrusted to him, and he will definitely do his best to help him get things done.

  In the end, Feng Wan was persuaded by him. Although she wasn't very optimistic about it, since Cook was so enthusiastic about it, why not just go along with it? Anyway, applying for a patent would be harmless to her son, and as for production, they could cross that bridge when they came to it. If there really was a huge market like he said, they could consider the details later.

  At that time, domestically, patent matters were not taken very seriously, and many people did not even know that the Patent Law existed.

  It's different abroad. Every time a technological innovation emerges, the first thing to do is to apply for a patent. Otherwise, once someone else gets there first, their own invention or technology will be restricted by others.

  Cook is so enthusiastic, largely because of a ham psychology. After all, they have been looking for such a thing for too long, and now that they have finally found something good, they naturally hope to let him out as soon as possible.

  Although he had already understood Lin Hong's circuit diagram and could make it by hand when he returned, he would not do such a thing. On the one hand, he was not that kind of person, and morally, he couldn't pass through. On the other hand, Lin Hong had helped him with a "big favor" before, and he had already recognized Lin Hong as his friend.

  He was more than happy to do things for his friends, and this friend seemed to be no ordinary one. This could be seen from their discussion just now.

  He believes that Lin Hong's road ahead is still very long, and at such a young age, he can design such a device. The design concept and understanding of basic circuits are simply beyond words. These basic circuits are broken down, and anyone with some electrical engineering foundation can roughly understand them. However, combining them in the current sequence and hierarchy, if no one had informed him beforehand, he estimates that only scientists from world-class research institutions could have guessed its purpose.

  Of course, if everything goes smoothly, Cook can also get a lot of benefits from it, which is also one of the important reasons why he is so enthusiastic.

  At the end of dinner, Cook repeatedly instructed Lin Hong to bring that finished product tomorrow. He was eager to verify its function. Moreover, he also made an appointment with Feng Wan to sign a power of attorney for the application of US patents tomorrow.

  Kuk was so excited to see Lin Hong and his friends off that he only then remembered the little Chinese girl waiting for an answer from him.

  Xu Wenjing looked at him calmly and asked, "Mr. Cook, the dinner party has ended. Shouldn't you fulfill your promise and tell me about bd7xzz's whereabouts?"

  "Oh, God!" Cook slapped his own head and rushed outside to take a look, only to find that Lin Hong and the others had already left by bus.

  Cook shrugged helplessly and said, "I'm extremely sorry, ss. Originally, I wanted to give a surprise, but... something unpredictable happened halfway through, I was too excited and forgot about it, I'm really sorry!"

  Xu Wenjing's eyes showed a puzzled color, she didn't speak, just looked at him.

  "The person I've been looking for is Lin Hong, he is bd7xzz." Finally, Cook revealed the answer.

  "What?" Xu Wenjing's eyes widened in surprise, losing her composure, "Are you sure you're not joking?"

  "Today is not April Fool's Day, everything I said is true. Stone is indeed bd7xzz, if you don't believe me, you can ask him yourself. I think it's easy to verify? Originally, I wanted to give a surprise, but I messed up this matter, sorry about that. He will come here again tomorrow, if you want to see him, you can also come here..."

  Xu Wenjing was stunned on the spot and didn't speak for a long time.

  I should have known it earlier!

  It was then! When I heard his voice at the airport, I felt a sense of familiarity and had an inexplicable feeling about him.

  It was like that just now at the dinner table too, feeling very close.

  I didn't even hear it, I'm so stupid!

  It's no wonder she did, because except for the first few times when Lin Hong communicated with her in his original voice, he used a middle-aged uncle's tone to communicate with her, which was a frequency-adjusted version of Lin Hong's voice to avoid being recognized as a young man by other players.

  Although Xu Wenjing knew that XZZ's actual age was not big, and should be younger than herself, the middle-aged uncle's voice still gave her a stronger psychological hint. This is the important reason why she didn't recognize him just now.

  "Stinky apprentice, you've seen your master and yet you still pretend not to recognize him, humph!" Xun Wenjing's eyes narrowed slightly.

  "It's okay, nothing happened, right?"

  Seeing her like this, Cook was startled for a moment and asked with concern.

  "It's nothing." Xu Wenjing suddenly laughed again, her smile was like a sudden burst of blooming flowers, and even Cook was slightly stunned.

  "Ah, so pretty, when she grows up, she'll definitely be a great beauty."

  "Thank you! Mr. Cook, anyway I still want to thank you today, thank you for telling me the answer, also very grateful for dinner, I'm going home now, goodbye!"

  With a wave of her hand to Cook, Xu Wenjing walked out of the Friendship Hotel's gate with quick and light steps.

  Not far from the main gate, a black Audi 100 official car was quietly parked. When Xu Wenjing walked over, the driver immediately came out and opened the door for her. After she got in, he drove slowly towards Zhongnanhai.
