No difference.
The personal port allows individuals to submit patents electronically;
The firm's port allows firms to submit patents to multiple clients at the same time through one port.
The firm's port is licensed by the State Intellectual Property Office, allowing one-to-many ports. Except that the agency has this authority to query and submit patents, there is no other way. The agency quality of the firm is supervised by the State Intellectual Property Bureau.
If the applicant's case is submitted through the personal port, then subsequent notices will be sent to the personal port; if the applicant is entrusted with an agency, then subsequent notices will be sent to the agency.
There are special circumstances: for example, when an individual pays the annual fee and feels that the agency fee is too expensive, then the individual submits the fee through his or her own account, and subsequent notifications will be sent directly to The personal port no longer accesses the agency, causing the agency to no longer be able to monitor patent developments, which may result in no notification of subsequent annual fees. So, sometimes don’t lose the big for the small.
