The EPC and PCT-EPO Guidelines 2023, published in preview mode a month ago, came into force on March 1, 2023, replacing the March 2022 edition.
The new EPC and PCT-EPO Guidelines are published on the EPO website in the three official languages of the EPO and can be downloaded for free in PDF format or accessed section by section in HTML format. The PDF version is available both as a "clean copy" and as a version showing all modifications. In each section of the HTML version, you can display what has changed in the new version by selecting the Show changes box in the upper right corner. A full list of revised chapters, with corresponding hyperlinks, is published with the corresponding guide.
