Versions

Fixed

• A missing USPTO key now opens the key setup directly instead of a generic "service unavailable".
• The patent-data keys page now says the keys are free and explains that server keys cover the trial while paid plans use your own.
• One canonical USPTO signup link.
• Bundled skills updated to the CLI v0.8.1 contract.

Changed

• Patent data now runs on FlowLeap's unified tools API. Versions before v0.2.2 can no longer search patents — please update.
• The in-app patent API guides now come from the live backend catalog, so new capabilities appear without an app update.

Fixed

• Testing your EPO/USPTO patent-data keys now gives a clear per-provider verdict, and the key setup explains that the keys are free.
• PDF text extraction (OCR) uses the same robust backend connection as everything else, with clearer guidance when sign-in or a trial is needed.
• Windows installers are now code-signed.

Fixed

• A rejected model-provider API key now says so. Chat previously ended the turn
• with the provider's own wording — OpenRouter answers an unrecognised key with
• "User not found." — followed by a stack trace, which read as though your
• FlowLeap account were missing rather than your key being wrong. The message
• now names the provider, tells you to check the key, and links Manage Models,
• keeping the provider's text as a supporting detail. A key that never reached
• the provider is reported differently from one that was refused.

Patent analytics over PATSTAT

• **Portfolio analytics** — aggregate a named applicant's filings by CPC/IPC
• class, office, year, family, and grant status, with harmonized entity
• resolution. Every figure carries its PATSTAT Data Edition.
• **Guarded SQL** — write read-only `SELECT` queries against the `flowleap.*`
• semantic views for landscapes, grant rates, citation impact, and inventor
• analytics that the typed commands do not cover.
• **Graph analytics** — six graph operations over the worldwide DOCDB citation
• network: who cites a patent (examiner versus applicant origin), citation and
• family paths between two patents, family coverage, and an applicant's
• co-applicant network. Every edge is tagged with a confidence level and a
• PATSTAT row reference.
• The agent now routes between keyword analytics, structured aggregation, and
• graph traversal on the shape of the question rather than its wording.

Provider-key handling

• The agent knows which patent-provider keys are connected and adapts instead
• of stalling: it does the work that needs no key, tells you exactly which key
• a blocked step wants, and resumes that step once you connect it.
• Key state is shown in the chat surface, so a missing EPO OPS or USPTO ODP
• credential is visible before a search fails.

Bundled skills

• Updated to FlowLeap CLI v0.6.0 — refreshed provider-key setup guidance,
• authentication states, and search recipes.
• Added the `flowleap-patstat-graph` skill for the new graph analytics.

Fixed

• Chat output panels no longer go blank when a streamed response re-renders.
• A patent lookup by number no longer drops its only matching record.
• An empty result set now reports that it is empty instead of reporting a
• size overrun, and a large result that is trimmed says so plainly.
• Class-based landscape questions route to portfolio analytics instead of
• free-text search.
• The GitHub Copilot walkthrough no longer appears in patent mode.

• First public release of **FlowLeap Patent AI** — an AI patent agent for
• patent professionals, built on the VS Code platform.

Patent research agent

• Chat-driven patent agent with 28 typed tools against the FlowLeap backend:
• EPO patent search (CQL, with natural-language query building), USPTO Open
• Data Portal search, applications and continuity chains, file-wrapper and
• office-action documents, enriched citation data (backward and forward, with
• X/Y/A relevance tagging), patent-law reference search (MPEP, EPC, EPO
• Guidelines), academic and non-patent literature search, claim analysis and
• comparison, patent details and figures, portfolio analytics, and report
• writing.
• 25 bundled patent skills covering the full lifecycle — invention disclosure,
• prior-art and novelty search, claim drafting and analysis, office-action
• response, freedom-to-operate, invalidity analysis, infringement charting,
• patent landscaping, maintenance-fee checks, and formatted patent reports.
• Project templates for common patent workflows.

Bring your own key

• Model access is BYOK: connect your own API key (Anthropic, OpenRouter, and
• other providers) — prompts and documents go directly from your machine to
• your model provider.
• Dedicated settings page for managing model and patent-provider credentials
• (EPO OPS, USPTO ODP).

Documents

• Built-in PDF viewer with OCR text extraction for prior-art documents and
• office actions.
• DOCX viewer and Markdown-to-PDF export for work products.

Platform

• FlowLeap account sign-in for backend access, with a free tier for patent
• data.
• Agent sessions window for long-running, reviewable agent work.
• macOS builds (Apple Silicon and Intel) are code-signed, notarized, and
• stapled. Windows installers (system and per-user) are Authenticode-signed.
