Charles Lewis is granted a United States patent on his Kin Hee filter coffee pot
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly and fully stated in the passage: 'Charles Lewis is granted a United States patent on his Kin Hee filter coffee pot' appears verbatim in the 1900 entry, with exact matching of subject, predicate, object, and time period.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage presents this as a factual historical record). The stance is appropriately 'asserts' as the passage states this as fact. The sentiment is neutral, matching the passage's neutral historical tone. The time qualifiers (when: 1900, valid_from: 1900, valid_to: 1900) match the passage's dating. The context is empty, which is appropriate as the passage provides no contextual restrictions. The quote appears verbatim in the passage and directly supports the claim.
