Implements a professional 7-step prior art search methodology combining:
Goal: Extract key features and define innovation scope
Process:
Output: Structured invention summary with key features
Questions to Ask:
Goal: Develop comprehensive search keyword list
Process:
Output: Keyword search strategy document
Example:
Primary: blockchain authentication
Synonyms: distributed ledger verification, cryptographic authentication
Technical: public key infrastructure, digital signature
Related: decentralized identity, trustless verification
Searches:
- "blockchain AND (authentication OR verification)"
- "(distributed ledger) AND (identity OR credential)"
- "cryptographic AND (login OR access control)"
Goal: Cast wide net to find relevant patents
Process:
Code:
from python.bigquery_search import BigQueryPatentSearch
searcher = BigQueryPatentSearch()
results = searcher.search_patents(
query="blockchain authentication",
limit=30,
country="US",
start_year=2015 # Look back 5-10 years
)
Output: List of 10-20 potentially relevant patents
Goal: Find relevant classification codes
Process:
Common CPC Categories:
Output: List of relevant CPC codes with descriptions
Goal: Comprehensive search within classifications
Process:
Code:
results = searcher.search_by_cpc(
cpc_code="G06F21/", # Security arrangements
limit=100,
country="US"
)
Output: Comprehensive list of potentially blocking patents
Goal: Understand technology evolution
Process:
Code:
# Search by year ranges
recent = searcher.search_patents(query, start_year=2022, end_year=2024)
older = searcher.search_patents(query, start_year=2015, end_year=2021)
Output: Timeline showing technology development
Goal: Professional assessment and recommendations
Process:
Output: Comprehensive patentability report
