Document Viewer Aligning PDF and XML

Some processes can benefit from restructuring or editing submitted documents. For example, patent examiners could benefit from viewing claims in a collapsible hierarchy, reflowing content tablet displays, or editing ex officio corrections. Accordingly, it can be beneficial to interact with the document in a Markup Language format such as XML which facilitates restructuring and editing. However, applicants largely refuse to adopt XML filing solutions proposed by the USPTO and the EPO. The present invention allows applicants to continue filing PDF for initial and subsequent submissions while facilitating a transition to a XML working process. After automatically capturing content, it provides an ergonomic interface, allowing users throughout the process to manually touch-up OCR artifacts, mathematical equations, and chemical structures. When both PDF and XML are available, examiners may seamlessly switch between formats and versions while retaining context and a given Annotation appears in all formats and versions.
