Structured reports vs conversational search
Perplexity recently launched Perplexity Patents, calling it “the world's first AI patent research agent.” It brings Perplexity's conversational AI search to the patent domain. PatentNexus is a dedicated patent intelligence platform that delivers structured patentability reports. Both use AI, but they solve different problems at different stages of the patent process.
Perplexity Patents is a conversational search tool. You ask a question in natural language — “has anyone patented a drone-based power line inspection system?” — and Perplexity returns AI-summarized answers with links to relevant patents. It uses semantic search to find results that keyword matching would miss. It's fast, free, and great for exploration.
PatentNexus is a structured analysis platform. You describe your invention and receive a 6-section patentability report: technology classification, prior art analysis with ranked results, patent landscape data, novelty assessment, claim gap identification, and suggested claim language. The output is a PDF you can hand to a patent attorney.
Perplexity Patents excels at semantic search — it understands the meaning behind your query and finds relevant patents even when they use different terminology. This is powerful for initial exploration when you don't know exactly what to search for.
PatentNexus goes beyond search. It automatically classifies your invention into CPC/IPC codes, runs multiple search strategies (semantic, classification-based, keyword), ranks results by relevance, and then analyzes what it finds — identifying which elements of your invention are covered by existing art and which represent potential novelty. The analysis is the product, not just the search results.
With Perplexity Patents, your output is a chat conversation. Useful for learning and exploration, but not structured for patent prosecution. You can't easily share a Perplexity chat with your attorney as the basis for a filing strategy.
PatentNexus generates a structured PDF report designed to be shared with patent professionals. Six sections, ranked prior art with similarity analysis, claim suggestions, and a patent landscape overview. This is the format attorneys expect and can act on immediately.
Perplexity Patents is free — it's part of the Perplexity search platform. This makes it the obvious choice for quick exploration and initial research.
PatentNexus offers free executive summaries, with full reports at $249 (Standard) and $499 (Comprehensive). The cost reflects the depth of analysis — you're paying for a structured patentability assessment, not just search results. For comparison, the same assessment from a patent attorney costs $5,000–$15,000.
Use Perplexity Patents when you're exploring an idea and want to quickly see if similar patents exist. It's perfect for early-stage research, learning about a technology space, or getting a quick sanity check before investing in a formal assessment.
Use PatentNexus when you're ready for a formal patentability assessment — when you need to know whether to invest in a patent application, need a report to share with your attorney, or want structured analysis with claim suggestions and landscape data.
The best approach: use Perplexity Patents to explore first, then run a PatentNexus report when you're serious about filing.
Perplexity Patents and PatentNexus are complementary tools, not competitors. Perplexity Patents is the best free option for quick patent exploration. PatentNexus is for when you need structured, actionable patentability analysis you can take to an attorney. Start with Perplexity to explore, then use PatentNexus when you're ready to make a decision.
