  "country": "US",
  "title": "Better Lab Tests with Engineered Humanized Antibodies",
  "original_title": "Reagent containing humanized antibody",
  "summary": "This patent describes a special lab test ingredient, a 'humanized antibody,' designed to make medical and research tests more accurate by preventing false alarms.",
  "what_it_does": "This patent describes an immunoassay reagent, which is a key ingredient for laboratory tests. This reagent contains a 'humanized antibody' that targets a specific substance (Claim 1). The special feature of this antibody is its ability to 'inhibit a non-specific reaction' (Claim 2), meaning it only binds to its intended target and avoids reacting with other similar substances that could cause false results. The patent also covers a 'kit' that includes this reagent (Claim 7) and an 'immunoassay method' for using it (Claim 8). For example, a diagnostic test for a specific virus would use this humanized antibody to accurately detect only that virus, ignoring other harmless substances in a blood sample.",
  "what_it_does_not_cover": [
    "Immunoassay reagents that use antibodies which are not 'humanized' (e.g., purely animal-derived antibodies).",
    "Humanized antibodies that do not specifically 'inhibit a non-specific reaction' (Claim 2).",
    "Lab tests that do not involve antibodies, such as those that detect DNA or RNA directly.",
    "Methods for inhibiting non-specific reactions that do not involve the use of a humanized antibody.",
    "Immunoassay methods where the humanized antibody is not brought into contact with the target substance (Claim 8)."
