Absolute
novelty describes the
patentability requirement that an
invention must not have been made available to the public anywhere in the world before its filing or priority date. In the UK (Patents Act 1977, section 2; European Patent Convention, Article 54) and Ireland (Patents Act 1992), novelty is assessed against the “state of the art”: any enabling disclosure—by document, product use, sale, oral presentation or any other means—counts if it was publicly accessible.
Key features:
- Worldwide scope (no territorial limits).
- An enabling disclosure to at least one person not bound by confidentiality can destroy novelty.
- Earlier‑filed but later‑published patent applications are novelty‑only prior art (Patents Act 1977, s.2(3)/EPC Art 54(3)).
- Very limited grace period: certain non‑prejudicial disclosures within six months are disregarded (evident abuse/breach of confidence, or display at an officially recognised international exhibition). There is no general grace period—applicant self‑disclosure is usually fatal.
Used in patent prosecution, prior art searches, validity opinions and transactional due diligence, absolute novelty is applied consistently across England & Wales, Scotland, Northern Ireland and Ireland through EPC alignment. Practically, maintain confidentiality and file before any public disclosure to preserve novelty and patent rights.
