One assignee leads clearly with 1,532 records in this dataset, more than double the fifth-place total of 156. Behind that leader sits a long tail of over 90 other ranked assignees plus many unranked filers, so the field is concentrated at the very top but still competitively open below it. The top 5 combined hold 29.5% of all 8,150 records in scope, and the top 10 hold 37.3%, meaning most filings sit outside even that group.

Filing volume grew steadily through the late 2010s, peaked in 2021 at 1,138 records, and had eased to 982 by 2024 — a 14% decline over that three-year span. That is best read as a cool-down from a filing peak rather than a collapse, particularly because publication lags actual filing by roughly 18 months, so the 2025-2026 figures in any dataset will always look lower than they eventually turn out to be. Judge momentum on complete years like 2024, not on the most recent partial year.

G06F, the electric digital data processing class, appears on 84.7% of all records in this corpus, making it by far the dominant classification. H04L (digital information transmission) follows at 23.2% and G06N (AI-based computing) at 11.2%, both well behind. Because a single record can carry several IPC classes, these percentages add up to more than 100%, and they should be read against the full 8,150-record total, not against each other.
