judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage's first entry. H.C. Lockwood from Baltimore was granted a United States patent on a coffee package in 1873, exactly as claimed.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to 'author' (the passage itself presents this as factual record). The stance is 'asserts' which matches the declarative nature of the passage. Sentiment is neutral, appropriate for a factual historical statement. The time is correctly set to 1873 with matching valid_from and valid_to dates. Context is empty, which is appropriate as the passage provides no restrictive context or sense distinction. The quote appears verbatim in the passage and directly supports the claim.
