The process and cost of patent application at home and abroad are roughly the same.

Do you mean that the process and cost of patent application in China and abroad are roughly the same? The patent application process at home and abroad is the same, but the cost is different. Because the patent application process at home and abroad is relatively the same, it is the steps of acceptance, disclosure, retrieval and preliminary examination. However, the cost of patent application abroad is very expensive, and it needs to pay agency fees and certain maintenance fees, which are not available in domestic patent applications. Therefore, the patent application process at home and abroad is the same, and the cost is different.
