Engineering Turnover and Lost Inventions: Capture the Work Before People Move On

Code stays when an engineer leaves. The understanding of why it works, what was tried first and what was actually new usually does not. I have seen companies discover a promising invention a year after its author moved on, and then struggle to describe it well enough for counsel to work with.

This is not a legal guide. Employment agreements, assignment terms and inventorship are matters for your counsel. It is a practical way to keep the technical story intact.

Why it gets lost

• Senior engineers are busy until their last day, then gone.
• Exit processes focus on access, equipment and handover of tickets, not on what was invented.
• Comments and commit messages describe what changed, rarely why the approach was novel.

A simple capture routine

1. Keep a short list of key systems and their main authors. Update it each quarter.
2. Hold a 30 minute invention conversation each quarter with the people behind the top systems. Ask what problem they solved, what they tried first and what surprised them.
3. Add one question to the exit process: "Is there anything you built here that you think was new?" Record the answer and dates.
4. Store the notes with your other invention records, not in a personal document that leaves with the person.

What a good record includes

The problem, the approach, how it differs from common methods, where it lives in the code, who contributed and approximate dates. Our free Invention Disclosure Record follows this structure.

When turnover is already high

If a reorganization or acquisition is coming, it is worth doing a focused review now rather than later. Our Codebase Invention Audit pairs a read-only code review with short interviews of the people still on the team.
