This dataset covers 14,940 published records matched to Trusted Execution Environment and related security terms between 2015 and the 2026 data cut-off. Filing volume peaked in 2020 at 1,656 records and eased to 961 by 2024, a 36% decline across that three-year span. The most recent one to two years in any such dataset are understated because publication typically lags filing by roughly 18 months, so the true 2025 and 2026 totals will rise as more records publish.

The ranking covers 100 assignees, not a top-10 or top-50 cut, and one filer leads with 2,235 records — more than five times the tenth-place total of 205. The top five assignees together hold 4,425 records, or 29.6% of the 14,940 records in scope, but that still leaves the majority of the corpus spread across the remaining ranked leaders and a long tail of smaller filers. The leaders include major device, cloud-platform and payment-network companies rather than a single specialist vendor.

The bulk of the corpus sits in two IPC subclasses: H04L, digital information transmission, covering 60.4% of the 14,940 records, and G06F, electric digital data processing, covering 56.6%. Wireless communication networks (H04W) and business/admin data processing (G06Q) form a smaller second tier at 16.2% and 15.4%. Because a single record can carry several IPC classes, these shares add up to more than 100% of the record total — they describe overlapping claim coverage, not mutually exclusive categories.
