What It Is

PatentFlare is an AI-powered infringement claim chart generation tool for patent professionals. It is not positioned as a general-purpose chatbot, but as a vertical workflow built around claim construction, evidence extraction, infringement mapping, and auditable citations. The site says its process was built and validated with input from patent litigation attorneys, and can generate a claim chart with evidence and analysis in minutes.

Core Capabilities

Its standout capability is “verifiable citations”: every piece of evidence is quoted verbatim from uploaded or provided source documents, with the document and page number labeled; citations that cannot be verified are discarded. It can also interpret terms based on the patent specification, score each limitation at the phrase level, and reduce overclaiming through an automatic second-pass audit. In terms of source materials, it supports PDFs, product webpage text, URLs, charts/schematics, and YouTube videos, and can analyze product images and structural diagrams—something with real value for hardware and structural claims.

Pricing and Trial

Pricing is straightforward: the first full claim chart is free, includes DOCX export, and does not require a credit card. After that, it costs US$129 per chart, with no subscription. For more than 10 charts per month, users can contact the company for bulk pricing, team accounts, and priority support. For litigation or licensing teams, per-chart billing makes project budgeting easier, but it is not cheap for occasional individual users.

Pros and Cons

Its strengths are its strong fit for legal workflows, emphasis on verbatim evidence, page-level traceability, editable DOCX/Excel exports, and the ability to show which claim elements are supported by evidence and where gaps remain. Compared with using ChatGPT directly, it places more emphasis on citation grounding, reducing the risk of fabricated references. The limitations are also clear: the site does not disclose the underlying model, API availability, or enterprise data protection details; support for Chinese patents and Chinese-language materials is unclear; and the company explicitly states that its output is not a substitute for attorney work product, so final legal judgment and review still require a lawyer.

Who It’s For and Access from China

PatentFlare is suitable for patent litigation attorneys, licensing and monetization teams, in-house IP counsel, and SEP analysis teams that need to quickly produce an editable first draft of an evidence-mapping claim chart. The site does not specify access from China, payment methods, or network availability, so these remain unknown. If Chinese-language support is insufficient, alternatives include using a general-purpose large language model with manual verification, or relying on local patent search and legal analysis workflows.
