Chapter 680: Can this be made?

Xishan No. 1 Courtyard, living room.

"I'm back."

Song Yao finished changing her shoes and walked over listlessly, lying on Xu Qingzhou, absorbing yang energy to relieve fatigue, "Professor Xu, work is so tiring."

"Do you want to consider being a woman who washes clothes, cooks, and takes care of children at home?"

Xu Qingzhou hugged the girl's waist, and the school beauty burrowed into his arms, a faint fragrance instantly entering his arms.

"Heh, keep dreaming!"

Song Yao chuckled twice.

She didn't expect this guy to want to rebel; she was the one who wanted to keep Xu Qingzhou.

"Humph, you're just double-standard, thinking about keeping me all day."

Xu Qingzhou exposed Song Yao's evil thoughts.

Song Yao didn't speak and played dead, rubbing against Xu Qingzhou again. After a tiring day, the most comfortable thing was to absorb Xu Qingzhou's yang energy like this...

During this period, she was still busy with patent layout and various subsequent promotions.

In terms of lithium dendrites, more than thirty patents have been determined.

Plus the previous Li-NAFION coating technology, dynamic self-repairing SEI film, etc., Lingdian Technology already has over 123 patents in hand.

Take CATL, for example; it has accumulated over 40,000 patents, and just last year it added 730 patents, covering technologies related to battery safety and interface optimization.

Patents.

Basically, a core innovation point of a product will be dismantled into multiple sub-technologies, such as structure, material, and process, and applied for patents separately.

This massive number of patents combined together is a patent barrier.

Lingdian Technology had already established a three-level patent system: core patents, defensive patents, and reserve patents.

According to Professor Li Daiyue's advice, they are currently considering establishing a fourth level—offensive patents—forming a "patent pool" through multiple patents, which can actively sue for infringement.

Simply put, walk others' paths so they have nowhere to walk.

The two hugged together, sitting quietly, thinking about the tranquility after the busyness.

Er Miao upstairs seemed to hear Song Yao's movement, swinging its tail downstairs, looking down at the bipedal beasts at the stairs.

The sofa was clearly so big, but it seemed it couldn't hold a cat's position...

It meowed twice, turned its head, and continued to lie on the windowsill of the study.

On the sofa, Xu Qingzhou felt it was about time, pinched the cheek of the girl in his arms, "If you've absorbed enough, let go, I'm going to cook."

Although Song Yao was reluctant, she still let go. After a tiring day, she planned to take a shower first.

Half an hour passed.

The two were already sitting in front of the dining table.

Seeing Song Yao come out with two large bowls of rice, Xu Qingzhou became happy, "Not on a diet anymore?"

"Don't worry about girls' business," Song Yao said angrily.

Xu Qingzhou shrugged his shoulders, eating his meal, and said: "Guo Ziyang said he would invite us to dinner this weekend."

"Jiahui also asked me this afternoon. You have time this weekend, right?"

"Saturday."

"Okay, I'll tell Jiahui..."

After eating.

Song Yao washed the dishes, while Xu Qingzhou went to the study to continue researching nitrogen/boron co-doped carbon nanotubes.

Friday, 3:00 PM.

Laboratory.

"Nitrogen/boron co-doped carbon nanotubes?"

Hu Jingxuan looked at the plan Xu Qingzhou handed her, a bit confused: "Isn't this material already abandoned?"

"Um, but when I was researching, I found that we could do some design, which could compensate for its defects to a certain extent..."

Xu Qingzhou had two dark circles under his eyes.

To make this set of plans, he stayed up until two o'clock last night and climbed up again at seven o'clock this morning.
