Common general knowledge meaning

Published by a LexisNexis IP expert
What does Common general knowledge mean?
In patent practice, common general knowledge (CGK) is the stock of information and routine techniques that the notional person skilled in the art would ordinarily know and accept at the relevant priority date. CGK is a case-law concept, not defined in statute. UK authorities (for example, General Tire v Firestone and KCI v Smith & Nephew) explain it as what is generally known and taken for granted in the field, including standard textbooks and widely used reference works and manuals, together with well-established, routine methods. Material is not CGK merely because it is publicly accessible or discoverable by a literature search; obscure, speculative or fringe publications will not usually qualify. CGK is central to patent validity and scope. It informs how the skilled person reads the specification and prior art, and is applied when assessing inventive step/obviousness, sufficiency/enablement and claim construction. It may justify combining prior art only where the skilled person would do so without hindsight, using their CGK. Usage is consistent across England & Wales, Scotland and Northern Ireland under the Patents Act 1977, and broadly mirrored in Ireland under the Patents Act 1992, where courts commonly consider UK and EPO jurisprudence.

It decided the defendant company directors, the Ahmeds, were not liable for procuring Lifestyle’s trade mark infringements, nor under a common design, because they lacked knowledge of the essential facts that made the use of the signs in question, by the company of which they were directors, wrongful. The Court further held the Ahmeds could not be ordered to account for profits made by the company and, on the facts found, had not personally gained from the infringements.

England and Wales Patents Court revokes two CureVac mRNA vaccine patents in BioNTech/Pfizer case: plausibility not established; insufficiency in fact; obvious over Thess ([2024] EWHC 2538 (Pat))

What are the practical implications of this case? The judgment offers insight into how the UK Patents Court currently treats plausibility. Applying the approach articulated by Lord Sumption in Warner‑Lambert v Actavis [2018] UKSC 56, and restated by Mr Justice Meade, the touchstone is that there must be a substantive basis to consider the claimed effect credible, not mere conjecture. Absent such a reason, plausibility fails. On that test, the judge held the Patents were not plausible. Nonetheless, he accepted that, in some instances, the necessary “positive reason” might flow solely from the skilled person’s common general knowledge (CGK). He cautioned, however, that this is more likely in mechanical arts than within the life sciences, and particularly not in the context of second medical use claims—the very scenario considered by the Supreme Court in Warner‑Lambert. In any case, an example of that kind would be a long way off...

Admissibility of Accused's Statements in Scots Criminal Trials: Hearsay Exceptions, Police Interviews, ECHR and Statutory Safeguards, Co-Accused, Implied Admissions, Mixed Statements, Special Knowledge Confessions

As a broad principle, hearsay does not qualify as admissible proof in Scottish criminal proceedings (see, for instance, Introduction: Stair Memorial Encyclopaedia [237]). Yet there are a number of recognised departures from that principle. The first and most straightforward exception in Scots Law permits hearsay to be led simply to demonstrate that a statement occurred (commonly termed primary hearsay). Such material, however, is not receivable as proof at trial of the truth of what was asserted (secondary hearsay). For further detail, see Introduction: Stair Memorial Encyclopaedia [237]. Accordingly, parties may adduce evidence to establish that words were spoken, which may bear upon a person’s knowledge or serve to account for later conduct; nevertheless, that evidence cannot establish that the content of the utterance was true and accurate. This Practice Note addresses the other main exception to the hearsay prohibition: statements made by the accused person, which are generally always admissible notwithstanding their inherently hearsay character. Witness statements As a general position, statements given by an individual while...
