filings read under mixed scope
7,748
4,101 granted, 3,647 pending, across 81 companies that filed
read under mixed scope: a space-first company's whole portfolio, a diversified group's spacecraft-class filings only, so the total counts records held rather than portfolios compared, a filing dates the work; a grant is the same invention two or three years older
What companies sought to protect, which is different from what they build or sell today. Filings are matched to company records by exact applicant name, a reviewed alias, or a name prefix of at least two words, so a group that files solely through sub-brands is under-counted rather than credited by guesswork. The classification shown is the one the patent office recorded.

Spacecraft-class filings by company
CPC B64G, spacecraft and their equipment, read in full for every company. This is the comparison the record supports: ranking on filings held would put a group we read in one class beside a company we read entirely, which is two different measurements in one chart.
