U.S. Patent Number 12,383,915 – Portable Fluid Spraying System
Every Tuesday, the United States Patent and Trademark Office publishes newly granted patents. This blog post is part of a weekly series in which I pick an interesting new patent that has Idaho connections and briefly describe it.
Inventor: Vance Turbeville (Kimberly, ID)
This week’s featured invention is a practical device. It has a housing with an internal water tank, pump, and battery. It even has wheels and a handle. It can be used to “to water plants, wash a car or boat, and the like.”
The independent claims in this patent are highly detailed, which suggests a relatively narrow scope of protection. While I haven’t reviewed the prosecution history of the patent, it’s likely that the original claims were broader but were incrementally narrowed in response to examiner rejections. This kind of evolution is typical in patent prosecution, where applicants often add specificity to overcome prior art or other objections.
Such claim narrowing underscores the critical role of the prosecution phase in shaping the final scope of a patent. Strategic responses during this stage can significantly influence the strength and enforceability of the resulting patent, making it a key focus for both applicants and their counsel.
