FlowLeap vs Rowan Patents: Drafting or Evidence?
Disclosure: FlowLeap is our product. Every statement about Rowan Patents below comes from Rowan Patents' own website or the cited source, fetched on 14 September 2026, and is cited in this page's sources. Rowan is a serious drafting environment, and the thing it does best, holding specification, claims and drawings in step so part references and terminology stay consistent, is work that very few products in this market have actually done.
TL;DR
Rowan Patents is where you write the application. FlowLeap is where you build the evidence around it, before the draft and after it, across more than one office. They compete less than the shared label "patent AI" suggests, and a practitioner who lives in figures could reasonably run both.
What each one is
Rowan Patents is a desktop drafting environment for patent practitioners. Clarivate acquired its maker, Rowan TELS, in July 2024, and describes the product as an integrated patent drafting and prosecution solution. It installs on Windows 10 or higher and macOS 10.14 or higher, wants 16 GB of RAM and recommends 32 GB for local language models or large applications. Specification, claims and drawings sit in one application, with part references synchronized, terminology held consistent, and dependencies tracked across claims and specification. Chemistry and biotechnology drafters get compound and sequence management and an integrated chemical structure tool. Generative AI appears as an assistant for drafting selected parts of the application, using your choice of local or cloud-based models.
FlowLeap is an agent workspace for the research and analysis around a matter. It searches USPTO and EPO patent data, WO publications through EPO OPS, and scientific literature, and it does not invent patent numbers or claim text: every cited document comes from a real search and conclusions link back to the passages behind them. Matters, drafts, figures and reports live in a folder on your own machine, and FlowLeap keeps no copy. The same tools are reachable from a command line and from an MCP server, so the work can happen inside an agent you already run.

Where Rowan Patents is strong
Drawings that stay in step with the text. The part numbering problem is the one drafting chore that no amount of prose generation solves, and Rowan attacks it directly: part references synchronized, terminology consistent, claim dependencies tracked across the whole application. If you draft mechanical or electrical cases where figures carry the disclosure, this is the feature to weigh, and FlowLeap has no equivalent.
Chemistry and life-science depth. Compound and sequence management with an integrated structure tool is a narrow, expensive thing to build, and most AI-native patent tools have not built it.
Checks that run on your own machine. The Review module looks for antecedent basis problems, unsupported claim concepts, informalities, part reference inconsistencies and undefined acronyms, and Rowan states that none of your data is sent to the cloud for those analyses. On top of that, files stay on your disk, cloud calls happen only when you invoke an operation that needs one, and anything that does reach Rowan's servers is erased within a day. That is a clear, checkable posture, and we are not going to claim to be more private than it.
A supervised-AI stance, stated plainly. Rowan positions the practitioner as holding full control of the drafting process, with task-based tools over inputs and outputs rather than an agent running ahead of you. For a firm whose partners are nervous about generative drafting, that framing is a feature.
Office action shells. Rowan Prosecution takes an application number or a copy of the action and produces the response package for Non-Final, Final and Restriction Requirement actions, working from USPTO records. If most of your volume is US office action responses on a repeating template, that automation is mature and FlowLeap does not emit a formatted filing package.
Where FlowLeap differs
The work before the draft, and the work after it. Rowan's documented surfaces are drafting, review and prosecution shells. FlowLeap covers the parts of a matter that surround those: prior art search across offices, claim analysis, freedom to operate, invalidity, infringement mapping and landscape analytics, with full-corpus analytics over 170 million publications.
More than one office, from live data. Rowan's prosecution module works from USPTO records. FlowLeap reads EPO and USPTO data plus WO publications through EPO OPS, which is what you need when a patent family spreads across jurisdictions or when an EP file matters as much as the US one.
The record ships with the report. Conclusions link back to the passages that support them, and cited documents come from searches that actually ran. Rowan's drafting assistants generate parts of the application from your inputs; that is a different job, and it does not produce a citation trail you can hand to a reviewer.
Your key, your provider, no meter. After the trial you bring your own model key and pay that provider directly, with no credits, no markup and no second meter. Rowan also supports bringing a model, but through Portkey or Azure OpenAI endpoints only, and an account manager has to switch the option on for your organization.
Full workflows inside the agent you already run. The MCP server puts 32 patent tools into Claude Code, Cursor, Codex, opencode, Cline, Gemini CLI, Windsurf, Zed, Roo Code and Goose. The CLI carries 26 commands, 32 bundled skills and 14 workflow recipes, and its data commands run on the same FlowLeap account. Rowan's help centre documents a desktop application and two web applications, with no API, command line or MCP surface.
A price you can read without a call. $39 a month or $199 a year, and a 7-day trial of the complete product with no credit card, free models inside the trial and shared EPO and USPTO data access.
Pricing, side by side
Clarivate does not publish a Rowan Patents subscription price on the product page; the page routes you to a demo request. One published number does exist. The NAPP member offer lists $600 per practitioner per month for associations of 1 to 20 members, $500 for 21 to 40, and $400 for 41 or more, with reviewing attorneys and assistants covered by a practitioner licence at no extra cost and Rowan AI Chat described as an optional addition. Rowan Prosecution is sold separately as a monthly subscription based on your volume, with setup charges possible for customized templates.
| FlowLeap | Rowan Patents | |
|---|---|---|
| Published price | $39 per month, $199 per year | Not published; NAPP member rate $400 to $600 per practitioner per month |
| How you buy | Sign up and start the trial | Request a demo |
| Model usage | Not included; your provider bills you directly | Local models, or your own endpoint once activated |
| Prosecution module | Included in the plan | Separate volume-based subscription |
The gap on the seat is real, but read it for what it is: these are not the same purchase. Rowan's number buys a drafting desk with drawing and chemistry tooling that FlowLeap does not have. FlowLeap's buys search, analysis and the evidence record around whatever you draft.
Who should choose which
| Choose Rowan Patents if | Choose FlowLeap if |
|---|---|
| Figures and part numbering are the bottleneck in your drafting | Search, analysis and opinions are the bottleneck in your matters |
| You draft chemistry or life-science cases with sequences and structures | You need EP and WO evidence alongside US records |
| Your volume is repeating US office action responses on templates | You want every finding traced to a source a reviewer can open |
| You want AI as a supervised, task-based assistant inside the draft | You want the tools inside Claude Code, Cursor or Codex |
| Procurement is comfortable with a demo and a quote | You want a published price and a trial you start yourself |
They are not mutually exclusive, and if you are weighing both, the honest test is to take one real matter and split it: run the search, the novelty read and the analysis in one, write the application in the other, and see which half of the work each tool actually made lighter.
