In 1964, Norelco, a subsidiary of Philips North America, launched the eponymous compact cassette cassette made with 3M chromium dioxide technology, and the Compact Cassette, which was registered as a trademark.

It took almost 5 years for Philips to push this tape to the industry standard, and almost all record studios have released music tapes that meet this standard.

In the late '60s, major VCR manufacturers such as SONY, Panasonic, and RCA successively introduced VCRs that matched this tape, and the latest models of these different brands had their own characteristics, but they all had one thing in common, they all used 3M's unique commercial-grade tape drive structure, and Dolby's B-type noise reduction system introduced in 1971.

If Daheng Technology wants to develop a Walkman project, it must obtain the latter two patent authorizations, chromium dioxide tape technology, and it is naturally best to be able to win.

All of this precious information was sold to Daheng by Andrew, a senior scientific and technological intelligence broker, and Zhang Heng felt that the high reward was worth it.

He believes that 3M will be happy to agree to his terms, the marginal benefits of the two own patents have long been recovered, and the additional licenses have no effect, and the Dolby license is a waste for 3M.

Of course, Daheng Technology can also seek to obtain a license from Dolby, but the cost will be very high, according to Andrew's intelligence, the amount can range from $10 to $250,000.

Moreover, this license fee is only an entry fee, even if it is a license taken from 3M, Daheng Technology still needs to pay a patent fee of 0.5% to Dolby for every product that uses the patent in the future.

It doesn't seem to be high, but if you calculate the total output value, everyone will be shocked.

THE WORLD'S FIRST WALKMAN, TPS-L2, LAUNCHED BY SONY IN THE PREVIOUS LIFE, WAS PRICED AT 33,000 YEN, OR $150.6, AND IT SOLD 450,000 UNITS IN 79 YEARS AND 730,000 UNITS IN 80 YEARS.

In the past two years, SONY has paid a total of $888,000 to Dolby in patent fees.

A company's product, Dolby can sit on half a million dollars a year, this is still in the early days of the product on the market, you can imagine what a promising business this is.

In 1981, a total of 3.75 million walkman-like walkman products were sold worldwide, of which SONY accounted for 4 percent.

This year, Dolby earned at least $2.8 million from this category of products alone, which can be called a daily profit.

In the previous life, Qualcomm also adopted this patent gold model and became a "patent troll" that the majority of mobile phone manufacturers dared not speak out.

Looking at it with a normal heart, this also shows the value of scientific research!

An era in which building an atomic bomb is not as good as selling tea and eggs, and an era in which a play can earn 60 million in three days with grease and powder, is definitely not a normal era.

If that's the norm, it's a shame for the country and the nation!

Zhang Heng, who came to 1972, was like a squirrel storing food for the winter, and was deliberately pulling small things to his home in order to establish his own patent kingdom.

An hour later, William returned with a smile on his face, and sure enough, it was good news.

3M agreed to license two of its own patents, as well as a license from Dolby, and even included a patent license: 3M's license for the head from Philips.

It was really breaking the iron shoes, Zhang Heng almost laughed out loud, he originally planned to go to Philips to discuss the matter after returning to Xiangjiang.

Philips' VCR heads are known for being mediocre, with mediocre performance and mediocre prices, but they are enough for most users.

In the future, if you want to launch a high-end version of the Walkman, you can go to two companies, RBAkai and Nakamichi, whose special material heads can be called enthusiast grade.

3M is so generous, naturally there are subsidiary conditions, that is, if Daheng Company authorizes patents externally in the future, 3M has the right of priority.

Daheng Company will focus on the electronic appliances and chip industry in the future, and the overlapping scope of 3M's business will not be very large, besides, it will also require Daheng to agree to external authorization, and 3M can be given priority, so Zhang Heng just sighed a little and agreed.

Then it was time to draw up the final contract, and William invited a few people to go up to the top floor of the hotel and open a luxurious presidential suite, which contained a study with a full range of office equipment, including fax machines, printers, and photocopiers.

"I just opened it with the company's approval, and my level is not enough to live in such a room. William explained with a smile, "However, this room will be reserved for Zhang Dong later, please forgive us for our poor hospitality before." ”

Zhang Heng bowed slightly, which can be regarded as leading his mind.

Lin Liang got busy, drafted the contract, faxed it to the 3M headquarters, the other party reviewed, the two sides discussed the modification by phone, several back and forth, and when the final version agreed by both parties was formed, it was 16 o'clock in the afternoon.

There are several contracts in total: self-owned patent licensing contract, patent licensing transfer contract, poster advertising creative purchase contract, and general agency contract in Greater North America.

Lin Liang, who has two discretionary powers of attorney from Huaheng Holdings and Daheng Holdings, signed and sealed these contracts one by one, and William, who has 3M's discretionary powers-of-charge, also signed and faxed them back to the headquarters.

Ten minutes later, the fax with the 3M company seal came back, and Lin Liang put it away, this contract already has legal effect.

Of course, William will also bring the original back to the company, stamp it and mail it to Daheng.

"Mr. Zhang, happy cooperation, before getting off work today, our finance department will wire the first payment and deposit. William held the contract, poster negatives and other documents, and shook hands with Zhang Heng with a smile to say goodbye.

Zhang Heng kindly reminded: "William, I have to remind you that the advertising contract with Ms. Hussey I signed is a one-time one, if you still need it in the future, I suggest that you contact her as soon as possible to confirm." ”

"Thank you Dong Zhang for reminding me, can you say hello to Ms. Hussey in advance?"

Zhang Heng shook the cash check in his hand and said with a smile: "I will, we are the best partners, these are small things." ”

William walked away with joy, and there was a faint sense of revenge in his heart.

Because of his insistence, Zhang Heng had to accept the US dollar as the settlement payment, and at the high-level briefing hosted by the 3M finance department not long ago, the US dollar was believed to continue to depreciate for a long time in the future.

Zhang Heng was also full of joy, in order to let him accept the payment in US dollars, 3M was even willing to pay for the goods once a quarter, which was simply a relief in the snow.

After coming to the United States, he had several in-depth discussions with Lin Liang, and communicated with Jiexi in Germany and He Jie in Xiangjiang, and Daheng made major adjustments to the internal financial settlement system.

As the general agent of foreign trade of Xiangjiang Daheng Printing Paper, Daheng Holdings is responsible for signing agency contracts with all foreign investors for Daheng Printing Paper related products and capital and goods exchanges.

In this way, all foreign trade profits will enter the offshore Daheng Holdings, which can not only legally avoid taxes, but also use this part of the profits in the international market in a unified and convenient manner.

Next, it's time to talk to that dedicated mining bond broker.
