Is a hydroponic system patented?
Short answer: specific designs of a hydroponic system have been patented many times, but "a hydroponic system" as a general idea is not what is protected. What matters is the exact combination of features in your version.
What our index shows
- 872 US and WO patent publications since 2000 have a title matching “hydroponic” or a close variant (our index of 9.7 million patent families; one publication per family).

What this means for your idea
Because patents cover specific combinations of features, the useful question is not “has a hydroponic system been patented?” but “has my combination of features been described before?” Outdoor products differ mostly in weatherproofing, power source, folding mechanisms and how they mount or anchor.
