How Fenix works
Your AI, made better at patent work
Fenix guides your assistant through patent work one well-defined step at a time, with your firm's templates and drawing tools, so it is not improvising.
Guided application drafting
Breaks an application into steps: disclosure, claims, figures, specification and review. Each step is saved to a record the attorney can see and edit.
Figure planning and drawing
Plans the figure set in an editable strategy document, then draws numbered flowcharts and block diagrams in patent drawing style.
Firm wording without AI
Writes figure descriptions, the brief description of drawings, boilerplate sections and standard remarks from your firm's templates, with no AI involved.
Office action responses
Imports the office action, analyzes novelty, obviousness and eligibility rejections, and drafts remarks and amendments for attorney approval.
USPTO record and cited references
Pulls the file history from the USPTO and the text of each cited reference, matched to claim limitations by paragraph or column and line.
Pre-filing review
Checks antecedent basis, claim structure, specification structure, figure consistency, priority coverage and subject-matter eligibility language before filing.
An automated patent practice
Fenix automates the work around drafting: docketing, USPTO forms, correspondence intake, tasks, review checklists and document filing.
Docketing with CPI and Patricia
Computes deadlines from USPTO events, emails docket reports, and works alongside CPI and Patricia docketing systems.
USPTO and PCT forms
Fills filing, IDS, prosecution, appeal, petition and PCT forms from matter data and applies the attorney's USPTO signature.
IDS management
Collects references from examiner citations, earlier IDS filings and emails into one citation list for the next disclosure statement.
Correspondence intake
Reads incoming USPTO correspondence and IDS emails, files them to the right matter and starts the follow-up work.
Workflow and task management
Tracks projects, assignments, review queues and attestation checklists, and runs automations triggered by matter events and due dates.
iManage integration
Saves matter documents, including signed filings, to iManage and retrieves them, so work product stays in the firm's document system.
Which AI assistant does Fenix work with?
Fenix works with the assistant you already use: Claude, including Claude desktop and Cowork, ChatGPT, Harvey, and other assistants that accept custom connectors. Fenix does not sell you a model or limit which one you choose, and you keep your assistant's full experience. Fenix adds what a general assistant lacks for patent work: the USPTO record, your matters, your firm's templates and a guided process. Each attorney signs in with their own Fenix login.
Fenix connector for Claude, ChatGPT and HarveyHow does Fenix make AI better at patent work?
A general assistant asked for a patent application improvises the whole document at once, and details drift. Fenix breaks the work into a guided series of smaller steps: disclosure, claims, figure planning, figures, specification and review. The assistant saves each step to a structured record the attorney can see and edit. Routine wording, such as figure descriptions and firm boilerplate, comes from your templates without AI, leaving the assistant only the work that needs judgment.
How does Fenix protect client data?
Each firm's data is stored in its own database, separate from every other firm's. Every connection belongs to one signed-in person, never a shared firm account, and an access token works for only one firm. Every action an assistant takes is logged with the person who authorized it. Fenix does not use client data to train AI models, and its AI providers' terms do not permit training on it.

Can I use Claude or ChatGPT to respond to a USPTO office action?
Yes, with Fenix connected. Fenix imports the office action from the USPTO, retrieves the cited references and guides the assistant through each rejection, including novelty, obviousness and subject-matter eligibility. The assistant stops for your approval before saving amendments or arguments, and Fenix produces the response document for you to review and file.
How does Fenix reduce AI hallucinations in patent drafting?
By giving the assistant less to improvise. Fenix splits drafting into small, defined steps, saves each to a structured record, supplies the USPTO file history and cited references, and generates routine wording from firm templates without AI. Fenix does not eliminate errors; the attorney still reviews every draft, as USPTO and ABA guidance on AI tools expect.
Is it safe to use confidential client information with Fenix?
Each firm's data sits in its own database. Every assistant connection belongs to one signed-in attorney, within their permissions, and every tool call is logged. Fenix does not use client data to train AI models, and its AI providers' terms do not permit training on it. Fenix's SOC 2 Type II report is pending. Firms should confirm their client-consent obligations.
Does Fenix use its own AI model?
No. Fenix does not sell you a model or restrict which one you use. You keep the assistant you already pay for, such as Claude, ChatGPT or Harvey, and connect it to Fenix as a custom connector. Fenix supplies the patent structure, records and tools that a general assistant lacks.
Can Fenix draft a patent application?
Fenix guides your AI assistant through drafting one under attorney direction: disclosure, claims, a figure strategy you can edit, figures, specification and pre-filing review. Figure descriptions and firm boilerplate come from your templates without AI. The attorney reviews each step and finalizes the application.
Which USPTO forms can Fenix fill out?
Fenix includes built-in USPTO and PCT forms for filing, information disclosure statements, powers of attorney, prosecution, appeals, petitions, post-allowance and reissue, including the Application Data Sheet and RCE transmittal. It fills them from matter data and applies the attorney's USPTO signature. Firms can also add their own templates.
Does Fenix file documents with the USPTO for me?
No. Fenix prepares the response, forms and filing package, and the attorney reviews, signs and files them through USPTO Patent Center. The practitioner's duty to verify each submission stays with the practitioner, where the USPTO's guidance on AI-assisted filings places it.
Does Fenix replace my patent docketing system?
It does not have to. Fenix can docket on its own, computing deadlines from USPTO events and emailing docket reports, or work alongside CPI and Patricia. Docketing is part of firm deployments; the free self-serve start covers office action responses only.
Does Fenix integrate with iManage?
Yes. Fenix can save matter documents to iManage and retrieve them, including signed filings, so drafts and filings stay in the firm's document management system.
How much does Fenix cost?
Fenix offers a free self-serve start at spark.fenix.ai for office action responses. Firm deployments with docketing, forms automation and document-management integration are priced per firm; contact the Fenix team for a quote.
