US Patent 9880989 Document annotation service

Organizations maintain and generate large amounts of documentation and entities of these organizations often need to collaborate on generating and reviewing this information. There is a need to maintain and store this documentation remotely in such a way that the entities of these organizations may collaborate with each other. To ensure that entities of the organization can collaborate on documents, a document annotation service is described that converts a text-based document, such as a word processing document, to a fixed-layout document, such as a coordinate-based document. Annotations can be received on the fixed-layout document. The annotations can then be mapped to the text-based document and downloaded to a user for viewing.
