What is required when filing a petition to revive an abandoned application?

When filing a petition to revive an abandoned trademark application, a statement of unintentional delay is required. This is crucial because the petitioner must demonstrate that the abandonment was not intentional, which helps in reinstating the application. Accompanying this statement, the petition fee must also be submitted. Additionally, any necessary documents relevant to the application or its abandonment need to be included to support the revival process.

The rationale behind requiring a statement of unintentional delay is rooted in the USPTO's policies aimed at ensuring that trademarks are not abandoned without good reason. The focus is on the applicant's intention, and thus proving that the abandonment was inadvertent is a key component of the petition.

Other options, while they may include some relevant elements, do not encompass the complete and accurate requirements as specified by the USPTO for reviving abandoned applications. For example, while proof of usage in commerce might be relevant for trademark registration and maintaining a registered mark, it is not a requirement for the revival process itself. Likewise, a statement of intentional delay contradicts the necessary premise, as petitions must assert that the delay was unintentional. Lastly, detailing changes made to the trademark isn't part of the revival petition process, which focuses on addressing the abandonment rather than changes
