Patentfield review
A patent search and analysis tool with AI screening and a capped free plan.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Patentfield brings professional patent search and analysis together for intellectual-property work in product development, research, and patent practice. Its web-based service combines field, command, and number search with AI semantic and similarity search, data visualization, and classification prediction. That makes it a fit for people who need to find and screen patent documents or examine patent data, rather than draft applications inside a dedicated workflow. The product is positioned for small, mid-market, and enterprise organizations, though its search limits are especially relevant to budget-conscious users.
The free plan offers a way to begin searching, but its allowance is capped at 30 searches in the registration month and 20 per month afterward. A 14-day free trial provides broader access to search and features. The paid pricing structure is not part of this listing, so buyers should assess the free allowance and trial against their expected research volume before choosing a plan. For occasional exploration, the free tier may be enough; sustained work involving frequent searches may call for evaluating the trial and available paid options.
Patentfield’s clearest strength is analysis and screening: users can combine similarity search with classification prediction, view patent data, and receive email alerts for saved search conditions. These capabilities support monitoring and investigation, but they do not extend to a verified drafting workflow or claim analysis. Teams that need those functions should consider a product centered on drafting or claim review instead. Choose Patentfield when patent search, visual analysis, and AI-assisted screening are the priority; look elsewhere when application drafting or claim-level analysis is central to the work.
