IPMS - Intellectual Property Management System

A modern, open-source platform for managing intellectual property portfolios. Built for companies, legal departments, patent attorneys, and innovation teams.

Features

• Asset Management - Track patents, trademarks, copyrights, and design rights through their full lifecycle
• Deadline Tracking - Never miss a renewal, filing, or response deadline
• Document Management - Store and manage filings, certificates, correspondence with approval workflows
• Portfolio Analytics - Group assets into portfolios and analyze portfolio health
• Workflow Automation - XState-powered state machines for asset lifecycle, filing, and document approval

Quick Start

Prerequisites: Node.js 20+, pnpm 9+

git clone https://github.com/melvin-corp/iptoassets.git
cd iptoassets
pnpm install
pnpm dev        # Start development server at http://localhost:5173
pnpm test       # Run test suite (59 tests)
pnpm check      # Run lint + typecheck + tests

Architecture

IPMS follows Clean Architecture with Functional Core / Imperative Shell in a pnpm monorepo.

apps/web (SvelteKit)          <- Imperative Shell (UI + API routes)
  |
  +-- packages/ui             <- Svelte 5 Atomic Design components
  +-- packages/state-machines <- XState 5 workflow actors
  +-- packages/application    <- Use cases + port interfaces
  +-- packages/infrastructure <- Repository implementations
  |     |
  |     v
  +-- packages/domain         <- Pure functional core (entities, rules)
        |
        v
      packages/shared         <- Branded types, Result<T,E>, value objects

Dependency rule: arrows only point downward. Domain depends on nothing. Application defines ports. Infrastructure implements them.
