| 71 | from python.bigquery_search import BigQueryPatentSearch |
| 72 | searcher = BigQueryPatentSearch() |
| 73 | |
| 74 | # Keyword search |
| 75 | results = searcher.search_patents( |
| 76 | query="blockchain authentication", |
| 77 | limit=50, |
| 78 | country="US", |
| 79 | start_year=2015, |
| 80 | end_year=2024 |
| 81 | ) |
| 82 | |
| 83 | # CPC classification search |
| 84 | cpc_results = searcher.search_by_cpc( |
| 85 | cpc_code="G06F21/", |
| 86 | limit=100 |
| 87 | ) |
| 88 | |
| 89 | # Get full patent details |
| 90 | patent = searcher.get_patent("US10123456B2") |
| 91 | ``` |
| 92 | |
