It is very important to know whether the agent is familiar with your technical field, whether it is a famous big agent or a powerful small agent, and whether the agent understands and accurately grasps your technical core. Because different technical fields are very different, it is best to choose agents and agents who are familiar with and good at your technical field.
It is ideal if you can entrust an agent with rich R&D experience. As an agent with R&D experience is entrusted to complete the work, the technical content of the client can be better understood, and the application strategy of defensive claims or offensive claims can be written in the claims, which makes it difficult to break through the independent claims of patents, with solid stability and the widest scope of protection. When writing patent claims, we should also consider the inventor's industry layout, evidence compensation in future litigation and other factors, so as to properly guide technicians to complete the evasion design of the corresponding technical route, which is simply more difficult for agents who only have legal knowledge but not enough R&D experience.
However, it should be noted that some so-called excellent and famous agency companies are responsible for writing application cases, and nominal agents are not really engaged in these jobs. It can be solved by the following methods: when choosing to cooperate with excellent and famous agency companies, some agents can be appointed as managers.
So objectively speaking, choosing an agency is essentially choosing an agent who writes patents. Looking for an agency with a moderate price and a professional manager will have a very high cost performance and authorization rate.
