This dataset’s assignee ranking returns 13 companies covering the full set of 20 records in scope — it is not a top-50 or top-100 cut, it is the entire ranked list the search produces. The leader holds only 3 records, and the count drops to 2 by fifth place, so no single company controls a large share of the filings. Anyone evaluating freedom to operate should treat this as a fragmented field of small portfolios rather than one with a dominant blocker.

Three-quarters of the 20 records in scope (75.0%) fall under G06F, the electric digital data processing IPC subclass, covering claims tied to software architecture, partitioning and processing management. H04L (digital information transmission) and G08G (traffic control systems) appear in smaller shares, 20.0% and 15.0% respectively. Because records can carry multiple IPC classes, these figures overlap rather than summing to 100%, but the pattern is clear: certification IP concentrates on the processing stack itself, not the surrounding communications or traffic-management systems.

The trend shows a peak of 6 filings in 2023, with activity tapering in the years after. A reliable growth rate cannot be calculated here because fewer than four complete years remain once publication lag is accounted for, and lag runs roughly 18 months from filing to publication. That means the most recent one to two years in the data almost certainly understate real filing activity, and the apparent decline should be treated as provisional until later publications catch up.
