Patent Intelligence · Pioneer Index
Patent pioneer index
Patents ranked by forward-to-backward citation ratio — identifying inventions that influenced far more than they built upon. A high ratio signals a true pioneer: a patent that started a new branch of the technology tree.

Top pioneer fwd citations
6,231
Forward citations
How many later patents cite this patent. A measure of downstream influence.
Backward citations
How many prior patents this patent cites. A measure of how much it builds on existing work.
Pioneer ratio
Forward ÷ backward. High ratio = outsize influence relative to prior art dependency. Low ratio = incremental improvement.
Influence score
Forward citations × ratio. Rewards patents that both had high reach AND innovated beyond their prior art foundation.

Methodology Notes
Influence score = forward citations × (forward ÷ backward). Patents with 0 backward citations use forward × 1.5 as a conservative estimate (may be the first in a new category). Only patents with ≥5 forward citations and ≥1 backward citation are ranked. Very new patents are underrepresented (less time to accumulate forward citations). Domain tag is the first tag in the enrichment array. Backward citation count includes all prior art references, not just patent citations.
