Published Workflows
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.
database patent searchkeyword filteringIPC code filteringstatus-based patent filtering
Stages
- 1.Patent search and retrieval(in_silico_filter)
To identify a broad initial set of patent families relevant to nanotechnology-based nucleic acid delivery systems for breast cancer.
Selection: Keywords and IPC codes related to breast cancer, nucleic acid therapies, and delivery platforms
- 2.Patent status and recency filtering(decision_gate)
To narrow the broad patent set to a recent active subset for detailed examination.
Selection: Active patents from the past five years (2020-2025)
- 3.Detailed examination of selected patents(secondary_characterization)
To characterize technological platforms, trends, and opportunities within the recent active patent subset.
Selection: Detailed examination of the filtered active subset
Steps
- 1.Search DWPI using keywords and IPC codes
Retrieve patents related to breast cancer, nucleic acid therapies, and delivery platforms.
A broad database search is needed before any filtering or prioritization can occur.
- 2.Classify documents by status and focus on recent active patents
Reduce the initial patent set to a more current and actionable subset.
Status and recency filtering follows broad retrieval so that detailed examination is limited to the most relevant active patents.
- 3.Examine selected patents to identify platforms and trendsdelivery platforms identified during analysis
Determine dominant technological platforms, geographic leaders, and thematic trends in the selected patent set.
Detailed characterization is performed after narrowing the corpus to a recent active subset to improve decision relevance.
Objective: Engineer and evaluate resveratrol nanoformulations that improve delivery performance while reducing safety risk.
Why it works: The review frames nanoencapsulation and formulation optimization as a way to address the physicochemical instability, poor permeability, and rapid metabolism that limit resveratrol efficacy.

Stages
- 1.Nanoformulation design and carrier selection(library_design)
The abstract identifies multiple carrier classes as promising approaches to improve resveratrol delivery performance.
Selection: Choose among nanodelivery system classes for resveratrol nanoencapsulation.
- 2.Formulation optimization(functional_characterization)
The review describes strategies to improve key formulation properties of existing nanoformulations.
- 3.In vivo safety-oriented testing across disease settings(in_vivo_validation)
The abstract explicitly states that in vivo testing is needed to avoid potential safety issues.
