&AI (YC S24)
AI workspace for patent litigation: prior art search, claim charts, invalidity analysis, and infringement detection
For patent litigators, &AI is the most workflow-complete tool we've reviewed — prior art search, element-by-element charts, and invalidity drafts in one place, with credits pooled at the organization level rather than locked to seats. The catch is cost predictability: the vendor's own July 2026 averages put a claim chart at 241 credits and a prior art search at 176, roughly $96.40 and $70.40 on pay as you go, or $60.25 and $44.00 on Pro monthly ($48.20 and $35.20 on Pro annual). If you file charts every month, the Pro bundle at $625/user/month with $0.25/credit after the included 2,500 is the better economics. Prosecutors should look at prosecution-focused tools instead.

Skip &AI if you're a patent prosecutor rather than a litigator, if you're a solo or small shop that can't absorb $625/user/month for Pro, or if you need a hard per-matter cost ceiling that credit-metered AI actions can't give you.
Credits only cover the included 2,500 on Pro, then every chart and search bills at $0.25/credit — a 241-credit claim chart still runs about $60.25 on Pro monthly even after you've paid the seat fee.
Pay as you go at $0.40/credit with no monthly commitment suits occasional and evaluation work; Pro at $625/user/month (or $500/user/month billed annually) with 2,500 credits at $0.25/credit after suits firms billing patent matters monthly. Enterprise is custom-priced with SSO, RBAC, single-tenant or self-hosted deployment, and passthrough invoicing. Cheaper than five-figure invalidity search opinions; priced above general-purpose legal AI seats that don't do element-by-element charts.

About &AI (YC S24)
&AI is an AI workspace built specifically for patent litigators, covering the arc of a matter from prior art search through claim charts to invalidity contentions. It targets Am Law 100 firms, IP boutiques, and in-house IP teams that need trial-ready work product faster than a manual research cycle allows. The core loop is search-to-chart: prior art search runs across patent applications and publications from major jurisdictions, non-patent literature such as research papers, standards, and clinical trials, and current or archival product listings including specifications, manuals, videos, and teardowns. Claim charts generate element by element with citations back to prior art and product documentation, plus figure annotation, and claim constructions are generated from the patent, its prosecution history, and family. Beyond charting, the platform drafts invalidity contentions, expert reports, and pitch decks through pre-formatted templates with smart variables and generation blocks, worked in a collaborative editor where your team and Andy—the built-in AI assistant—refine documents together. Portfolio tables let you query thousands of documents at once, apply prompts to each with shared context, and slice results with natural-language or metadata filters. A personalized real-time feed of new patent litigation triages cases to the right partner based on your team's prior experience. Security is built for confidential legal work: SOC 2 Type II certified, no training on your or your clients' data with zero data retention policies, SAML SSO and role-based access controls, and encryption in transit and at rest, with single-tenant or self-hosted deployment available at the Enterprise tier.
Behind the Verdict
&AI's pitch is narrow and it holds up: this is a patent litigation workspace, not a general legal assistant with patent features bolted on. The search-to-chart loop is the real product. Prior art search pulls patent applications and publications from major jurisdictions, non-patent literature like research papers, standards, and clinical trials, and product evidence including current and archival listings, specifications, manuals, videos, and teardowns. That product-evidence coverage is unusual and matters for infringement work, where the evidence is a datasheet or a teardown video rather than a patent. Charts generate element by element with citations back to the source, and figure annotation happens inside the chart, which is the part most manual workflows get sloppy about. Claim constructions are generated from the patent, its prosecution history, and family. The assistant, Andy, takes those inputs further into invalidity contentions, expert reports, and pitch decks via pre-formatted templates with smart variables and generation blocks. The editor is collaborative, so your team and Andy refine the same document rather than passing drafts around. Portfolio tables are the sleeper feature for plaintiffs and licensing teams: query thousands of documents simultaneously, apply prompts with shared context to extract structured data, then slice with natural language or metadata to find the products worth a full chart. The business-development feed is a genuine differentiator for firms — a personalized real-time feed of new patent litigation with pitch recommendations triaged to the right partner based on your team's prior experience, plus configurable alerts. Weaknesses are real. Everything is credit-metered, so a broad multi-claim chart costs meaningfully more than a focused one, and a team that doesn't track usage can be surprised at month end. Pay as you go at $0.40/credit with no monthly commitment is flexible but expensive per action; Pro at $625/user/month includes 2,500 credits and drops the rate to $0.25/credit, and annual billing brings that to $500/user/month (billed annually). There is no $0 tier — the entry point is a 7-day free trial. Solo practitioners and small IP shops will struggle with the Pro price. The workspace is web-based, so teams that need mobile or offline access are out of luck. And while output is trial-oriented, it is still draft work product: attorney review of every chart and contention is not optional. Where it fits: Am Law 100 firms and IP boutiques producing claim charts on a recurring basis; in-house IP counsel doing litigation prep, infringement mining, and portfolio analysis; and IP business-development teams hunting new matters. Where it doesn't: patent prosecutors, occasional users who need a hard cost ceiling, and anyone expecting court-ready output straight out of the tool.

Real-world workflow fit
Concrete scenarios for the personas &AI (YC S24) actually fits — and what changes day-one when you adopt it.
You're staffed on an invalidity contention with a tight deadline. You run prior art searches across patents, non-patent literature, and product documentation, then generate element-by-element claim charts with citations and figure annotations, and hand Andy the case context to draft the invalidity contentions from a pre-formatted template.
Outcome: A first-pass contention set with cited charts lands in the collaborative editor in hours rather than days, and the drafting partner reviews and refines instead of starting from a blank page.
You need to mine your own portfolio for evidence-of-use against a competitor's products. You load thousands of product documents into portfolio tables, apply prompts with shared context to extract structured data, then filter with natural language to isolate the products worth a full chart.
Outcome: You prioritize which products deserve full charting before spending outside-counsel budget on the deep work, and you walk into the next strategy meeting with ranked evidence.
You subscribe to the Opportunities add-on and set configurable alerts and filters on the real-time feed of new patent litigation. Pitch recommendations land triaged to the partner with matching prior experience.
Outcome: New matters get routed to the right partner without someone manually scanning filings, and pitch decks are drafted from templates with the case context already loaded.
Use Cases
- Search for prior art across global patents, non-patent literature, and product documentation to invalidate a patent claim.
- Generate element-by-element infringement claim charts with automated citations to product evidence.
- Draft invalidity contentions or expert reports using pre-formatted templates and AI assistance.
- Monitor a real-time feed of new patent filings and litigation to identify pitch opportunities for your firm.
- Analyze thousands of products simultaneously using portfolio tables to detect infringement patterns.
- Build claim constructions automatically from the patent, prosecution history, and family.
- Produce pitch decks and pitch materials for prospective patent litigation clients.
Limitations
- All plans are credit-based, with AI-heavy actions consuming credits (average 241 credits per claim chart and 176 credits per prior art search as of July 2026).
- Pay as you go costs $0.40 per credit with no monthly commitment; Pro is $625/user/month with 2,500 credits included and $0.25/credit after, or $500/user/month billed annually.
- The Opportunities add-on is $175/monthly user for attorneys and $50/monthly non-user attorney.
- Usage varies widely by matter, so different searches, charts, and case stages consume different credit levels — a broad multi-claim chart can cost several times a focused one.
- There is a 7-day free trial rather than a free tier, and the workspace is web-based.

Switching to or from &AI (YC S24)
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From manual prior art search across USPTO, Espacenet, and Google Patents: run the same query set in &AI and keep the citations back to source for your chart.
- →From a general-purpose legal AI assistant: move discovery and chart drafting into &AI's element-by-element chart workflow instead of prompt-drafting claim language by hand.
- →From spreadsheets for infringement mining: replace per-product rows with portfolio tables and shared-context prompts across thousands of documents at once.
- →From Outlook alerts and manual docket scanning for business development: replace with the Opportunities real-time feed and team-based pitch triage.
- ↗To a prosecution-focused drafting tool: &AI is litigation-oriented, so application drafting and prosecution work moves to a dedicated prosecution platform.
- ↗To a general-purpose legal AI assistant: if your work is mostly research and drafting without element-by-element charts, a broader legal assistant may cover it.
- ↗To manual workflow: exports to Word, PowerPoint, and Excel let you take generated charts and contentions out of the workspace if you stop subscribing.
