What's wrong with the patent tax credit? I want to buy some patents to offset the tax.

The purchased patents obtained special invoices. If the purchased patent is used for taxable items and a special invoice is obtained, it can be deducted if the buyer is a general taxpayer. New technology enterprises need at least two invention patents to reduce tax. The original VAT general taxpayer purchases services, intangible assets or real estate, and the VAT indicated on the special VAT invoice obtained is the input tax, which can be deducted from the output tax.
