Why the 1980s beats the 2020s on commercial score
The 1980s saw the first wave of software patents, biotech (Genentech, Cetus), and PC hardware. These were foundational platform patents that created entire industries with no prior art competition. The 2020s patents, while innovative, operate in more crowded, price-competitive technology markets where commercial leverage per patent is lower.
Why the 1960s-70s patents are so highly cited
The 1960s and 70s produced the integrated circuit, the microprocessor, Ethernet, PCR foundations, and internet precursors. These are the ur-patents — everything built since cites them. High forward citation count in older patents is the signature of truly foundational IP that seeded multiple subsequent technology generations.
How to read the commercial premium score
Commercial premium is each decade's avg commercial score relative to the global mean across all 837 enriched patents. A score above 1.0 means that decade produced more commercially leverageable patents than average. The 1980s (1.13×) and 1870s-1880s (Edison era) are the two peaks.
