Ann Makosinski filed a U.S. patent application for her thermoelectrically powered portable light source, formalizing the intellectual property behind her Hollow Flashlight invention.
On January 8, 2016, a U.S. patent application was filed for a thermoelectrically powered portable light source, listing Ann Makosinski as an inventor. This filing represented a critical step in transforming her prize-winning science fair project into a legally protected, commercially viable invention.
Patent applications require rigorous documentation of a device's novelty, utility, and non-obviousness, and the filing process reflects the technical maturation of what began as a teenage science project into an engineering innovation with real intellectual property value. The application detailed the thermoelectric generator mechanism, the heat-differential technology, and its application in a portable, battery-free lighting device.
This filing set the stage for the eventual grant of U.S. Patent No. 9,723,659 in 2017, and demonstrated Makosinski's commitment to pursuing her invention beyond the science fair stage into formal commercialization and protection. It also marked her transition from student inventor to a young entrepreneur actively building a technology portfolio, eventually leading to the founding of her company, Makotronics Enterprises Inc.
Filing a patent as a teenager was itself notable, underscoring both her technical sophistication and business acumen at a young age, and it laid important groundwork for her later patents and product lines, including educational toys built on the same thermoelectric principles.
