An agency with strong strength and sufficient internal resources can satisfy you.
The high success rate of application mainly depends on whether the agency is professional enough.
The risk is small. If the agency is professional enough and the search is detailed enough, the risk will naturally be small.
Patent application still depends on what type of patent you want to apply for.
Such as invention patents, utility model patents, and appearance patents.
At present, patent examination is gradually becoming stricter.
At this time, there needs to be enough trust between you and the agent so that the agent can fully understand your patent.
If you have any questions, please ask.
