judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The quote explicitly states that 'In 1904, Sigmund Sternau, J.P. Steppe, and L. Strassberger, assignors to S. Sternau & Co., New York, were granted a United States patent on a percolator.' All elements of the claim—the subject (L. Strassberger), predicate (was granted patent on), object (percolator), and time (1904)—are directly stated in the passage.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is appropriately set to 'author' since the passage is a historical narrative without attribution to a named source. The stance of 'asserts' and sentiment of 'neutral' match the factual, neutral tone of the passage. The time qualifier correctly identifies 1904 with valid_from as 1904 and valid_to as null, matching the passage's temporal scope. The context is appropriately empty as the passage provides no specific contextual restriction beyond the percolator itself. The quote appears verbatim in the passage and directly supports the claim that L. Strassberger was granted a patent on a percolator in 1904.
