Filing momentum
Filings by year - recent years still publishing
| Year | Filings | Foreign |
|---|---|---|
| 2022 | 3 | 3 |
| 2023 | 5 | 4 |
| 2024 | 5 | 5 |
| 2025 | 6 | 5 |
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.
