a) General 

Disclosures on the internet are generally regarded as part of the state of the art within the meaning of Art. 54(2) EPC. Information disclosed on the internet or in online databases is considered to be publicly available as of the date it was publicly posted (Guidelines G‑IV, 7.5 – March 2022 version).

The appropriate standard of proof for internet disclosures is the balance of probabilities (T 286/10, T 2227/11).
