Patent Intelligence · Talent Migration
Where do inventors go?
Patent filings leave a paper trail of talent migration. When an inventor files patents at Company A, then later at Company B, that's a real signal — visible in the USPTO record long before it shows up on LinkedIn. These are the talent flows the industry rarely talks about.

How migration is detected
An inventor 'migrated' if their earliest patent at Company B was filed after their earliest patent at Company A, with a gap of 1–8 years. This catches genuine career moves while excluding brief consulting relationships or concurrent appointments. The detection is conservative — real migration rates are higher.
Why patent records reveal this
When an inventor joins a new employer, their subsequent patents list the new assignee. This assignment record in the USPTO becomes a historical record of employment. It's not perfect (independent inventors, contractors, spinouts all create noise), but for large companies filing many patents, the signal is strong.
What talent flows mean strategically
A company consistently losing inventors to startups is building the next generation of competitors. A company consistently gaining from academia may be the commercialization engine for a research field. Net flow over time is a measure of whether a company is building or eroding its technical talent base.
