&AI

&AI is a specialized AI platform built for patent litigators and in‑house patent teams who need to move quickly from case intake to trial‑ready analysis. According to the official site, it focuses on end‑to‑end patent workflows such as prior art search, invalidity analysis, and evidence‑of‑use, all within a secure, collaborative workspace. This makes &AI an attractive option if you are evaluating the best patent litigation AI tool 2026 and looking for a professional‑grade solution rather than a generic chatbot.

​At its core, &AI combines powerful search, structured analysis, and drafting tools into one environment designed around the realities of patent disputes. The platform delivers global prior art search, litigation‑ready claim charts, and AI‑assisted drafts so that patent litigators can produce work product fast enough for pitches yet strong enough for court. A dedicated AI agent called Andy works across these tools on your behalf, using your configurations and context to automate repetitive steps while leaving the strategic decisions to the human team.

​One of the key strengths of &AI is its search capability across patents, non‑patent literature, and products. The platform lets you search patent documents and applications from major jurisdictions alongside research papers, standards, clinical trials, and more, helping you surface prior art that opponents might miss. In addition, &AI searches product listings, specifications, manuals, videos, and teardowns, which is especially valuable for evidence‑of‑use and identifying how real‑world products overlap with asserted claims.

​Beyond search, &AI provides automated claim charting that is tailored for invalidity and evidence‑of‑use work. You can generate element‑by‑element claim charts with citations to prior art or product documentation, which significantly reduces the time required to move from raw references to a structured legal position. The system also supports claim construction by pulling from the as‑filed application, prosecution history, related family, and other relevant materials to propose constructions grounded in the record.

​Drafting is another central pillar of the &AI workflow. The platform includes pre‑formatted templates with smart variables and generation blocks, allowing you to produce invalidity contentions, expert reports, and pitch materials that are consistent and easy to update. A collaborative editor lets your team and the AI refine documents in real time, which means &AI can assist both with the first draft and with iterative revisions based on feedback from partners, clients, or co‑counsel.

​Tables in &AI are designed for large‑scale opportunity analysis rather than simple spreadsheets. You can query thousands of documents in parallel, apply prompts with shared context, and extract structured data to answer questions about infringement patterns or litigation opportunities. Natural‑language filters and metadata‑based views help you slice and sort this data so you can quickly see which patents or products are worth deeper investment and which should be deprioritized.

​From a pricing perspective, &AI offers three main tiers: Core, Pro, and Enterprise. Core is priced at $375 per monthly user and includes 1,500 credits, with additional usage billed at $0.25 per credit. Pro is $625 per monthly user with 2,500 included credits, also at $0.25 per additional credit, while Enterprise offers custom pricing that is tailored to firm‑wide or corporate needs.

​Functionally, each tier maps to different depth of access. Core provides limited, public‑only access to &AI, including patent, NPL, and product search, prosecution and global family views, claim construction, invalidity and evidence‑of‑use charts, default draft and pitch templates, and exports to Word, PowerPoint, and Excel. Pro unlocks unrestricted access, Andy the AI patent assistant, portfolio and document tables, document uploads, custom prompt libraries, custom templates, and advanced instructions and annotations. Enterprise adds SSO and role‑based access control, priority support, single‑tenant architecture, self‑hosted models, passthrough invoicing, workflow automation, and custom integrations.

​Compared with more general legal AI tools, &AI is clearly positioned as a niche platform focused solely on patents and IP due diligence. Instead of trying to cover every legal practice area, it goes deep on patent workflows, from global prior art search to trial‑ready charts and drafts, which is a strong differentiator if you care about domain‑specific quality and repeatability. In that sense, someone searching for an &AI review or for the best patent litigation AI tool 2026 will likely appreciate that the platform is opinionated around how patent litigators actually work, rather than offering a generic document assistant.

​Security and confidentiality are treated as first‑class requirements. The official site highlights enterprise‑grade security, including SAML SSO, role‑based access controls, and encryption in transit and at rest, with an option to run in public‑only mode that disables access to confidential data altogether. &AI and its subprocessors do not train on your or your clients’ data and operate under strict zero data retention policies, which is critical for firms handling sensitive litigation matters.

​Getting started with &AI typically begins with a demo rather than a self‑serve sign‑up. The pricing page invites users to book a demo or email support to see the platform in action, understand how credits work for searches, claim charts, and interactions with Andy, and discuss configuration options that fit existing workflows. This sales‑assisted onboarding is common for high‑value B2B legal tools where configuration, data access, and training need to be tailored to the team’s docket and processes.

​To get the most value from &AI, it helps to anchor your usage around specific workflows rather than ad‑hoc experimentation. For example, you can standardize how the team runs prior art searches and builds invalidity charts for new cases, encode preferred templates and prompts into the system, and then let Andy and the AI actions handle the heavy lifting at scale. Monitoring credit consumption across Core and Pro users can also help you right‑size plans and decide when an Enterprise deployment with workflow automation and custom integrations makes sense.

​As with any AI tool in legal practice, &AI has some natural limitations. The terms of service emphasize that AI output can be unpredictable or incorrect, and users remain responsible for verifying accuracy, quality, and usability of the work product. Additionally, Core users operate in public‑only mode and cannot upload documents or confidential context, which may be restrictive for some litigation scenarios but is ideal for organizations prioritizing strict data boundaries.

​&AI fits neatly into broader AI trends in 2026, where domain‑specific agentic systems are increasingly favored over generic models. The introduction of Andy as an AI agent for patent work aligns with the move toward autonomous, workflow‑aware assistants that can orchestrate multiple tools on behalf of professionals. For firms and patent teams looking ahead, adopting a platform like &AI can be a way to institutionalize knowledge, scale expert workflows, and stay competitive as AI sets new baselines for speed and thoroughness in patent litigation.
