EPC.App is an annotated European Patent Convention (EPC), which focuses on finding the most relevant information quickly. On more than 400 coloured pages, all articles, rules and protocols of the EPC as well as the Rules relating to Fees are fully reproduced. These are provided with selected abstracts from the Examination Guidelines, Official Journal articles and case law, as well as numerous cross-references. For quick access, parts of the EPC are provided with an edge index visible on the closed book's edge, articles are always started at the top of a page, and related rules of the Implementing Regulations are assigned to the articles. The commenting is performed in a two-column layout, which allows non-disrupted reading of the legal texts in the left column, as well as authors' comments assigned to the individual paragraphs in the right column. Comments are generally kept in a short style, reduced to the essentials, and distinct in colour from official texts. Authors' comments can also be found as short references within the legal texts, as well as below them in the form of more detailed summaries of the legal situation. The texts are further provided with coloured markings of important key terms, time limits, fees, languages, and legal consequences. Some space is kept free in the right column and below the legal texts to add your own comments.

In addition to this printed version, the entire content of the EPC.App is also available as an electronic book implemented as a web browser application (App), which allows each registered user to add own comments electronically and to receive updates from the authors without losing own user comments. Via the App, users can edit the content (e.g. remove individual authors' markings or comments and add own ones), have their adaptations saved in a personal cloud storage, access and navigate the annotated EPC from anywhere via an internet connection, receive automatic updates of legal texts and authors' comments, and create a printable PDF-file, which includes all self-edited annotations and closely reproduces the layout displayed on the web browser, corresponding to this printed version.

The November 2018 Edition has been updated to the legal status valid as of 01 November 2018 (including the Examination Guidelines of November 2018), clearly indicates law coming into force on this date, and is dedicated for use in the European Qualifying Examination 2019.
