Workflow Stage Observations
Patent search and retrieval
Why this stage exists: To identify a broad initial set of patent families relevant to nanotechnology-based nucleic acid delivery systems for breast cancer.
Selection basis: Keywords and IPC codes related to breast cancer, nucleic acid therapies, and delivery platforms
Advance criteria: Patent families matching the search strategy were retained for subsequent filtering.
Enriches for: topic relevance
Patent status and recency filtering
Why this stage exists: To narrow the broad patent set to a recent active subset for detailed examination.
Selection basis: Active patents from the past five years (2020-2025)
Advance criteria: Patents classified as active and within 2020-2025 were selected for detailed examination.
Decision gate: Documents were classified as alive, dead, or indeterminate, and the analysis focused on active patents.
Higher fidelity: yes
Enriches for: current relevance, active intellectual property
Guards against: inactive patents
Detailed examination of selected patents
Why this stage exists: To characterize technological platforms, trends, and opportunities within the recent active patent subset.
Selection basis: Detailed examination of the filtered active subset
Advance criteria: Not explicitly stated in the abstract.
Higher fidelity: yes
Enriches for: platform prevalence, emerging trends, R&D opportunities
Preserves downstream axes: decision relevance for research and development
Workflow Logic
Workflow evidenceSource 1
Objective: Analyze the global patent landscape of nanotechnology-based delivery systems for nucleic acid therapies in breast cancer to identify key technological platforms, emerging trends, and research and development opportunities.
Why it works: The workflow combines database retrieval with topic-specific keywords, IPC codes, and status/time filters to reduce a broad patent corpus to a more decision-relevant active subset.
Priority logic: The analysis first captures a broad set of patent families, then prioritizes active patents from the past five years for detailed examination.
Validation strategy: The abstract describes detailed examination of the filtered active patent subset to identify platforms, trends, and opportunities.
Target properties: recent patent activity, platform prevalence, technology trends, innovation opportunities
Target techniques: database patent search, keyword filtering, IPC code filtering, status-based patent filtering
Workflow Step Observations
Search DWPI using keywords and IPC codes
Purpose: Retrieve patents related to breast cancer, nucleic acid therapies, and delivery platforms.
Why now: A broad database search is needed before any filtering or prioritization can occur.
Targets properties: topic relevance
Classify documents by status and focus on recent active patents
Purpose: Reduce the initial patent set to a more current and actionable subset.
Why now: Status and recency filtering follows broad retrieval so that detailed examination is limited to the most relevant active patents.
Decision gate: The study focused on active patents from the past five years.
Targets properties: current relevance, active status
Examine selected patents to identify platforms and trends
Purpose: Determine dominant technological platforms, geographic leaders, and thematic trends in the selected patent set.
Why now: Detailed characterization is performed after narrowing the corpus to a recent active subset to improve decision relevance.
Validation focus: Characterization of platform prevalence and thematic focus within the selected patent set.
Targets properties: platform prevalence, technology trends, geographic leadership
Evidence Snippets
A patent landscape analysis was conducted using the Derwent World Patents Index (DWPI, Clarivate Analytics). The search strategy combined keywords and International Patent Classification (IPC) codes related to breast cancer, nucleic acid therapies, and delivery platforms. A total of 1,084 patent families were identified. Filters were applied to classify documents as alive, dead, or indeterminate, focusing on active patents from the past five years (2020-2025), resulting in 323 patents selected for details examination.
