"What's the problem?" Lin Tian was startled by Professor Xue, that old man's way of talking was startling, making one think that something major had happened.
"Of course it's about the patent, this prescription must be patented; otherwise, if the formula leaks and someone else gets it, and they apply for the patent before you do, they could turn around and sue you for infringement, then you'd have nowhere to cry," Professor Xue said loudly.
Patent? Lin Tian was taken aback, he hadn't thought about that aspect; the prescription was won from the Japanese, and he didn't know if they had applied for a patent. If they had already applied, then he would indeed have been played by the Japanese.
Because in that case, he could only use it privately and couldn't sell it as a product, otherwise, it would be considered infringement. If he were sued in an international court by the Japanese, that would be a very troublesome matter.
