the manufacture and sale of which were discontinued in 1915
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The final sentence explicitly states that a percolator (patented by Charles Nelson and assigned to S. Sternau & Co.) had "the manufacture and sale of which were discontinued in 1915," which directly supports the subject, predicate, object, and temporal details of the claim.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. Viewpoint (author), stance (asserts), sentiment (neutral), time (1915), and quote are all accurate and properly extracted. The context qualifier is empty, which is appropriate since the passage provides no specific contextual restriction beyond identifying it as a percolator. However, there is a minor ambiguity in how the claim frames the relationship: the passage states 'the manufacture and sale of which were discontinued in 1915' referring to the percolator made by S. Sternau & Co., but the claim's predicate could be interpreted as attributing the discontinuation action directly to the company as subject, when the passage is actually describing a property of the product. The qualifier structure is technically faithful to what the passage conveys, though the semantic framing is slightly compressed.
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.

- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote provided matches the passage verbatim, confirming that Sigmund Sternau was granted a United States patent on a percolator in 1904.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (not a named source within the passage). The stance is 'asserts' which matches the factual presentation in the passage. The sentiment is neutral, appropriate for a straightforward historical fact. The time qualifier 'in 1904' matches the passage exactly. The context is empty, which is appropriate as the passage does not restrict the claim to a particular sense or role. The quote appears verbatim in the passage and directly supports the claim about Sigmund Sternau being granted a patent on a percolator in 1904.

- groundedness 1.00 pass — The claim is directly stated in the passage. The quoted sentence explicitly states that J.P. Steppe (along with Sigmund Sternau and L. Strassberger) were granted a United States patent on a percolator in 1904.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (not a named source), the stance is accurately 'asserts', sentiment is appropriately neutral, the time is correctly stated as 'in 1904' with valid_from=1904 and valid_to=null, context is empty as the passage provides no additional sense or role restriction, and the quote appears verbatim in the passage supporting the claim about J.P. Steppe being granted a patent on a percolator.

- 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.
Six others were granted to Charles Nelson, and assigned to S. Sternau & Co., in 1912 and 1913, for a percolator
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The text explicitly states that 'Six others were granted to Charles Nelson, and assigned to S. Sternau & Co., in 1912 and 1913, for a percolator,' confirming that Charles Nelson was granted patents on percolators during those years.
- qualifier_fidelity 0.95 pass — The claim is largely faithful to the passage. All qualifiers are correct: viewpoint is author (the passage itself makes the assertion), stance is asserts, sentiment is neutral, time correctly specifies 1912 and 1913, context is appropriately empty since no specific sense restriction is mentioned, and the quote appears verbatim and supports the claim. Minor deduction only for context being empty string rather than null, which is a minor schema formatting difference but the substance is correct.
