Among the above patents, only two invention patents are authorized: karaoke scoring device and method (No.3) and karaoke scoring equipment (No.5); The applicant is a Japanese company: Yamaha Company; Taiwan Province Company: Lianfa Technology Co., Ltd.
Since everyone basically has no patents, most of them can be used for free. However, if Japanese companies sue, domestic manufacturers and TV stations that are manufacturing and using related equipment may be involved.
However, the companies with patent rights are Japanese and Taiwan Province companies, which is relatively better.
In addition, if the technology used by everyone is different from the technical scheme of the authorized patent, there will be no infringement.
If you have a scheme, which is also a voice scoring software, it depends on whether your scheme and other implementation schemes are innovative. To achieve certain innovation, you can apply for an invention patent.
In addition, software can be patented and does not need to be combined with hardware.
The cost of patent licensing should be discussed with the patentee. But we must first find out the true value of the patent.
I hope I can help you.
