Is it better for an individual to apply for a patent by an agency or by himself?

If the individual has not received the professional training of patent agents and lacks the corresponding practical experience, it is best to entrust an agency to handle it.

The advantages are: the invention can be written accurately, the scope of protection is reasonable, and time is saved.

disadvantages: the cost is slightly higher.

if you apply for a patent yourself, you can save some money, but the quality of the document will be compromised, and even it will not pass the examination, which is time-consuming and laborious.
