Quick answer
This backend system interview question asks you to design a distributed patent & innovation management platform. Aim for a design that meets its requirements at the stated scale, then explain its main components, data flow and trade-offs. Interviewers want to see how you scope the problem, size it and defend each choice.
The problem
Design a Distributed Patent & Innovation Management Platform. Large technology enterprises use this system to securely capture internal invention disclosures, manage the rigorous legal review workflow, and search for "prior art" (existing patents that might invalidate a new idea).
Inventors submit confidential disclosures containing detailed technical descriptions and heavy attachments. These submissions move through a strict state machine (Draft, Legal Review, Prior-Art Search, Approved, Filed). During the process, patent engineers perform complex, full-text searches across both a massive public repository of global patents and the enterprise's own highly confidential internal disclosures. The system must securely orchestrate this workflow, store heavy assets, and serve low-latency search results without ever exposing internal trade secrets to the wrong users.
What must a distributed patent & innovation management platform do?
- Invention Submission: Accept highly confidential disclosures including rich metadata and heavy attachments (PDFs, CAD files, diagrams).
- Workflow Orchestration: Manage the transition of submissions through a multi-stage approval state machine, including an immutable audit log of status changes.

What do interviewers look for?
In any backend system design round.
- Clarifies the requirements before drawing anything
- Uses a few numbers that actually change the design
- Draws a clear path from the client to storage
- Picks storage and caching with reasons, not by habit
- Explains what breaks first under load and how to fix it
- States trade-offs openly instead of claiming a perfect design
Questions people ask about this interview question
- Which design type is this question?
- It is a backend system question. You design a distributed patent & innovation management platform and explain your choices the way you would in an interview.
- Is this question asked at entry level?
- It is marked Medium. Entry-level engineers can practise it, but it expects you to reason about requirements and trade-offs, not only list components.
- What should I cover first?
- Start with the requirements: what the system must do, how well it must do it and which numbers change the design. Agree on scope with the interviewer before you design anything.
- Can I practise it for free?
- It is a premium question. Sign up and unlock it once for 10 credits; it then stays unlocked. When you finish, Lala, your personalized AI mentor, can review your design for 30 credits.
