Free search vs AI-powered analysis
Google Patents is a free tool for browsing and reading patents. PatentNexus is an AI-powered patentability platform that analyzes 166M+ patents and generates structured reports. They serve fundamentally different purposes — one is a search engine, the other is an analyst.
Google Patents is completely free — you can search and read any patent at no cost. PatentNexus offers a free tier with executive summaries and technology classification, with full 6-section patentability reports at $249 and comprehensive analysis at $499. The question is whether free search alone is sufficient, or whether you need structured analysis.
Google Patents supports keyword search with basic filters (inventor, assignee, date, CPC code). You need to know what you're looking for and construct your own queries. PatentNexus uses AI to automatically classify your technology into CPC codes, then runs multiple search strategies — semantic search, classification-based search, and keyword search — to find the most relevant prior art without requiring patent expertise.
Google Patents provides no analysis. It shows you patent documents and lets you read them. Determining relevance, assessing novelty, and identifying claim gaps is entirely up to you. PatentNexus generates a structured 6-section report: executive summary, technology classification, prior art analysis with ranked patents, patent landscape, novelty and claim gap assessment, and recommendations with suggested claim language.
Use Google Patentsif you want to browse specific patents, look up a known patent number, or do preliminary research to understand a technology area. It's an excellent free reference tool.
Use PatentNexuswhen you need to answer the question "Is my invention patentable?" — when you need comprehensive prior art analysis, novelty assessment, and actionable recommendations before investing in a patent application.
Google Patents and PatentNexus are complementary, not competing. Google Patents is a free search tool — great for browsing and reading individual patents. PatentNexus is an AI analyst that transforms a plain-language invention description into a structured patentability assessment. Use Google Patents when you want to look something up. Use PatentNexus when you need to make a decision about whether to file.
