Why are all patent applications handled by agency companies?

1, because the agency is familiar with the practical rules and procedures of patent application, authorization and application. If it is our personal application, the process is complicated or we don't know much about it.

2, can effectively cooperate with the management of patent fees, remind to pay the annual fee.

3. Patents make their literature writing different from pure technical literature, especially claims and specifications. The quality of writing can directly affect whether the patent can be authorized and the speed of patent examination and approval by the patent office, and the writing of patent claims will also affect the scope of patent protection in the future. In this way, others can't infringe, and if they infringe, they need to pay you a fee and so on.
