First French patent (1806)
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage, which explicitly states 'First French patent (1806), 699' in the index of percolators. This directly confirms that the first French patent for a percolator was issued in 1806.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is appropriately 'author' since the passage presents this as factual information without attributing it to a named source. The stance 'asserts' matches the declarative presentation. Sentiment is neutral, which is appropriate for a factual claim. The time qualifier correctly reflects the date (1806) stated in the passage. Context is empty, which is appropriate as the passage provides no restrictive context beyond the subject itself. The quote 'First French patent (1806)' appears verbatim in the passage and directly supports the claim about when the first French patent for a percolator was issued.
