Patent Desk
What the companies we track are trying to build: 7,621 filings from 75 companies, as the United States patent office recorded them. A filing dates the work; a grant is the same invention about 28 months older.

CPC B64G, complete for every company
2026
most recent filing year
2024 is the last complete one
Two measures sit on this page and they are not interchangeable. Filings held is what we have read for a company, and for a diversified group that is its spacecraft-class filings only, because a portfolio over 1,500 applications is not a space signal. Spacecraft class is CPC B64G and is complete for every company here, which makes it the one figure that compares across the table.
Filings per year
An application publishes about eighteen months after it is filed, so 2025 and 2026 are still filling in and their bars will keep rising. Read them as the edge of the record rather than as a fall in activity.
Who is filing in the spacecraft class
CPC B64G, spacecraft and their equipment. Read in full for every company, so these bars compare directly.
Ordered by the spacecraft class, the column that means the same thing for every company. "Filings held" is what we read for each, which for a diversified group is its spacecraft-class filings only, so that column does not rank.

Which way the filing rate is moving
Filings in 2022–2024 against 2019–2021. Both windows have fully published, which is why neither is recent: comparing against a year that is still filling in would show every company falling. Each row compares a company against itself, on whatever we read for it, so a trend here holds even where a level would not compare.

What this covers, and what it does not
- United States filings only. A company that files first at the European, Japanese or Chinese office appears here only once it also files in the United States, so the non-US companies on this page are under-counted against the US ones.
- Attribution is by applicant name, because the office publishes no assignee identifier. Exact match or a curated alias, plus a prefix expansion for names of two words or more. A group filing solely under sub-brands is missed rather than credited by guesswork, and the applicant name as filed is in the table above.
- Read for the spacecraft class only, because the whole portfolio is not a space signal: BAE Systems, Boeing, Honeywell Aerospace, Lockheed Martin, Mitsubishi Heavy Industries, Northrop Grumman, RTX, Rolls-Royce, Safran, Thales, Viasat. Every other company here was read in full.
- Counts move as the office publishes. 2025 onward will keep rising for another eighteen months.
- 833 filings are listed under two company records, where a group and its space division are both tracked here. Totals count each filing once; a company row reports what that company filed.
- A filing is an attempt, not a product. It records what a company thought worth protecting on the date it was filed.
