What are the EPC.App / PCT.App?

EPC.App is an annotated European Patent Convention (EPC) and PCT.App an annotated Patent Cooperation Treaty (PCT), which allow each user to further annotate them electronically and to receive updates from the authors while retaining individual user annotations.

EPC.App /PCT.App are printable electronic books implemented as a web browser application (App), which offer for (already more than 1000) registered users:

  • to access and navigate the annotated legal text from anywhere via an internet connection
  • to adapt authors' annotations and legal contents to personal preferencesarrow_drop_down
    • remove individual authors' markings
    • change marking styles and colors
    • hide individual authors' comments and legal contents

    • comments as separate text blocks (with links to other parts)

  • to order a correspondingly customized color paperback with up-to-date content and typed user comments

For whom are the EPC.App / PCT.App?

EPC.App and PCT.App are intended for both the Practitioner and the Trainee.
