An RCBO is a type of circuit breaker with two functions. 1  To protect life. 2  To protect an overload on a circuit â overcurrent and short circuit.
When the United States Patent and Trademark Office (USPTO) intends to issue a patent, it sends the applicant a Notice of Allowance. For this to happen, an inventor provides information such as product description, design, and blueprints or drawings.
The USPTO will issue an official filing receipt by email if the application is filed electronically or by mail if it is filed on paper. A serial number will be assigned, and the details of the application should appear on the USPTOâs website within 14 days of filing. The progress of the application may be tracked at http://tsdr.uspto.gov/. Typically, an application is examined three to four months after filing.
