It is hard to predict how long it will take for an application to mature into a registration since many factors can affect the process. Generally, an applicant will receive a filing receipt approximately six months after filing. In addition, you should receive a response from the Patent and Trademark Office within six to seven months of filing the application.
However, the total application processing time may be anywhere from a year to several years. This depends on the basis for filing and any legal issues that arise in the examination process.
