  "patent_number": "US 5273995",
  "country": "US",
  "title": "How a Cholesterol-Lowering Drug Molecule Was Patented",
  "original_title": "[R-(R*R*)]-2-(4-fluorophenyl)-β,δ-dihydroxy-5-(1-methylethyl-3-phenyl-4-[(phenylamino) carbonyl]- 1H-pyrrole-1-heptanoic acid, its lactone form and salts thereof",
  "summary": "This patent protects the specific chemical structure of a molecule designed to lower cholesterol, including its various salt forms and its use in medicine.",
  "what_it_does": "This patent specifically claims a complex organic molecule, identified by its chemical name and structure, that is designed to treat high cholesterol. It covers the molecule itself, including its acid and lactone forms, as well as various pharmaceutically acceptable salts like sodium, potassium, calcium, and magnesium salts. Claim 11 describes a pharmaceutical composition containing this molecule for treating hypercholesterolemia (high cholesterol). Claim 12 outlines a method for treating high cholesterol in humans by administering this molecule.",
  "what_it_does_not_cover": [
    "Does not cover other types of cholesterol-lowering drugs that do not use this specific chemical structure.",
    "Does not cover the synthesis process or manufacturing methods for the molecule.",
    "Does not cover the use of the molecule for treating conditions other than hypercholesterolemia.",
    "Does not cover the molecule if it is not in a pharmaceutically acceptable salt form.",
    "Does not cover the molecule if it is not in the specific stereochemical configuration claimed."
