- Always use quotation marks around all citations: "exact citation text"
- Use the specific citations from each claim's limitation analysis
- Attribute each citation to the correct patent publication number
- Present translated citations naturally without mentioning the translation process
- Insert the disclaimer at the end of the citation if it was translated
## ANALYSIS REQUIREMENTS
- Analyze the limitation_results in each claim chart to understand coverage
- Use the coverage, strength, and confidence assessments from the limitation analyses
- Calculate coverage patterns across the patents in the strategy
- Focus on practical, actionable strategy recommendations
- Structure for immediate use in invalidity contentions or IPR petitions
- Base all assessments strictly on the actual coverage data provided
## FORMATTING REQUIREMENTS
- Use clear section headers and subheaders with proper markdown formatting
- Each limitation element must have its own clearly labeled subsection
- All citations must be in quotation marks and attributed to the correct patent
