US Patent 12383854 covers positive pressure air filtration system design for livestock facilities. The library record carries the patent number and the subject matter; the full inventor list is not held here.
A patent occupies a different evidentiary position from the studies that surround it in this library. It establishes that a particular arrangement was claimed as novel and was granted, which is a statement about the claim and its examination, not a measurement of field performance. The engineering literature on positive pressure filtration is carried by Ramirez and Hoff 2016 on fan selection, static pressure budgeting and filter bank sizing, and by Smith, Holck and Carman 2019 on siting and sampling in commercial installations. Those are the sources that report what positive pressure systems do once they are running.
For a producer or designer, the practical use of a patent record is orientation rather than specification. It indicates where design attention in the sector has been directed and what arrangements are held as proprietary, which can matter when comparing offered systems. Performance expectations should be set from the measurement literature, and the patent text should be read directly before any claim about its scope is relied on.
