Patent Agent
- A patent agent can prepare and file your application for a new invention, or I can help you do it yourself.
- A patent agent can handle all the paperwork and responses to make sure that your application describes your invention completely, includes enforceable claims, and makes sure your application complies with all the formalities that the patent office requires to be ready for examination.
- A patent agent can respond to office actions from an examiner, such as objections, rejections, and restriction requirements, and can explain what options the inventor has at each of these obstacles.
- A patent agent can file an appeal of an examiner’s decision or action, using the PTAB (Patent Trials and Appeals Board) system set up within the patent office.
