Is a stroller patented?

Short answer: specific designs of a stroller have been patented many times, but "a stroller" as a general idea is not what is protected. What matters is the exact combination of features in your version.

  • 1,824 US and WO patent publications since 2000 have a title matching “stroller” or a close variant (our index of 9.7 million patent families; one publication per family).

  • Most frequent assignees in those matches: WONDERLAND SWITZERLAND AG (86), LINK TREASURE LTD (42), GOODBABY GROUP CORP (38), WONDERLAND NURSERY GOODS (35).

What this means for your idea

Because patents cover specific combinations of features, the useful question is not “has a stroller been patented?” but “has my combination of features been described before?” Baby and child products are heavily patented and safety-driven; compare the locking, restraint and cleaning features carefully.
