83% Complete Claim Charts in 5 Minutes

Claim charting follows a familiar routine: pull the patent, pull the prior art or product materials, open Word, build a table. Copy each limitation into the left column. Hunt for evidence. Paste. Format citations. Repeat. 

After thousands of exported charts and countless conversations with users, &AI built Charts to shorten that loop without taking control away from you.

Create a strong first-draft chart in minutes

On the platform, you can generate a claim chart from a target patent and one or more materials, which may be patent documents, non-patent literature, specification sheets, or product teardowns (including video). For each claim element, &AI proposes supporting evidence from your materials with pinpoint citations and a short relevance rationale. If you need additional support, you can run keyword and semantic search across everything you’ve uploaded.

In an internal review of exported charts from the &AI platform, we found that approximately 83% of the evidence included in the final export was present in our first pass, for both invalidity and evidence-of-use charts.

Above all, you stay in control throughout: accept, reject, or refine each suggestion. Nothing is included in an export unless you approve it.

Compare references at a glance

The summary view illustrates how each document maps to each claim element, which is particularly useful for invalidity charts. Rather than charting one reference to completion, you can generate drafts for several and select the strongest reference before committing.

This way, gaps and overlaps surface sooner, so you can select the strongest reference (or the best combination) before you invest time polishing.

Maintain case context as positions evolve

Claim charts are living documents, so when constructions or strategy change, Charts can adapt in tandem. Add an Annotation with your updates, and create a new draft that reflects that direction, without starting from scratch.

Format your way

Finally, we know that both you and your firm have their own way of doing things. Charts supports dozens of export settings for boilerplate, citation formats, fonts, figure alignment, claim‑element labeling, and more. Set firm-wide defaults with per-user overrides to reduce post-export formatting.

If a setting you need is missing, we’ll build it.
