Key facts
Coverage
What does this patent actually cover?
While specific claimclaimA numbered sentence at the end of a patent that legally defines what the inventor owns. The most important section.Read more → details are unavailable for this patent, titled 'Submarine boat,' it describes the fundamental components and operation of an early submersible vessel. John P. Holland's designs typically included a hull capable of withstanding water pressure, ballast tanks for diving and surfacing, and a propulsion system for underwater travel. Such a submarine would submerge by filling its ballast tanks with water, then surface by expelling the water using compressed air. It would also feature control surfaces, like hydroplanes, to manage depth and direction while submerged.
The gap
What does this patent NOT cover?
- Does not cover submarines propelled by nuclear reactors or advanced air-independent propulsion systems.
- Does not cover surface-only naval vessels like battleships or destroyers.
- Does not cover remotely operated underwater vehicles (ROVs) or autonomous underwater vehicles (AUVs) without human crews.
- Does not cover diving bells or other stationary underwater habitats.
- Does not cover submersibles designed exclusively for deep-sea exploration without military capabilities.
These exclusions are unique to PatentBrief — derived from the actual claim language, not patent-office boilerplate.
