IP.appify platform allows you to fine tune and build your own legal reference for both EPC and PCT, that will never be outdated.
As an alternative to working on-line, the EPC part is also available as a stand-alone book with author's comments (and cross-references) on Amazon (.de or .com or .co.uk) in English or German.
The main author for the EPC is Dr. Christoph Schindler. This already includes enough comments and references to answer most of the questions at the EQE if you have studied, and are familiar enough with the law to be able to find relevant articles and rules. See my review of last year's edition, which I used to answer the EQE 2019 D paper.
This does not include PCT - this will eventually also be available as a stand-alone book with just the author's comments. We have just finished the first edition for on-line use, and we are currently fine-tuning the page content and the length for printing. I am the main author for the PCT part.
