Filing momentum
Filings by year - recent years still publishing
| Year | Filings | Foreign |
|---|---|---|

| 2024 | 39 | 39 |
| 2025 | 51 | 51 |
| 2026partial | 18 | 18 |
Patents publish ~18 months after they're filed, so the current year is always incomplete. The Rising / Steady / Cooling signal ignores it and compares only fully-published years - read a dip in the latest year as data still coming in, not a decline.
