Unearth forgotten inventions
Patents filed during eras of obscurity — no funding, no spotlight, no commercial future.
Era of Obscurity
ALL ERAS
Any year before 2006 — guaranteed expired
GILDED AGE 1870–1900
Massive invention output — wealth consolidated, independent inventors shut out
WORLD WAR I 1914–1918
Civilian R&D abandoned — military commandeered all capital and attention
GREAT DEPRESSION 1929–1939
No funding, no commercialization — patents filed and died on paper
WORLD WAR II 1939–1945
Civilian technology shelved indefinitely — inventors waited for a world that moved on
POST-WAR RECESSION 1946–1952
Brief but brutal — reconversion chaos swallowed small inventors whole
SPACE RACE 1957–1969
All capital and public attention funneled to aerospace — everything else went dark
OIL CRISIS 1973–1979
Economic shock killed development pipelines — energy patents especially buried
PRE-INTERNET ERA 1985–2002
Pre-internet inventions completely overshadowed — dot-com euphoria erased everything before it
Jurisdiction
◈ All eras selected — results guaranteed expired (pre-2006)
