Who Is Lonnie Johnson and What Are His Key Patents
Lonnie Johnson is an American inventor and engineer who holds more than 120 U.S. patents as of the latest public records, according to the U.S. Patent and Trademark Office. He is best known for inventing the Super Soaker water gun, which became one of the top-selling toys in the 1990s and generated billions in retail sales. His patent portfolio spans fluid dynamics, energy conversion, and thermal management systems, as documented in patent databases and company filings U.S. Patent and Trademark Office.
Johnson founded Johnson Research Academy and later Johnson Energy Storage, focusing on advanced battery and energy technologies. His work on the Johnson Thermoelectric Energy Converter, or JTEC, is protected by multiple patents describing a solid-state heat engine that converts heat directly into electricity. The technology has drawn attention from defense and aerospace sectors, and Johnson has publicly discussed its potential for high-efficiency power generation Forbes.
Lonnie Johnson Patents in the Super Soaker and Toy Industry
Super Soaker Patent History and Market Impact
The original Super Soaker patent, titled "Pressure Chamber Water Gun," was granted in the early 1990s and became the foundation for a line of high-performance water guns. Johnson licensed the technology to Larami Corporation, which was later acquired by Hasbro, and the brand remains a major player in the outdoor toy market. The patents describe a pressurized reservoir system that uses air pressure to propel water at distances far beyond conventional squirt guns.
Hasbro continues to release new Super Soaker models under licensing agreements tied to Johnson's intellectual property. The brand regularly appears in global toy sales rankings, and Hasbro's annual reports reference the Super Soaker line as a significant contributor to revenue in the outdoor and water play category Hasbro. Johnson's royalties from these patents have been a primary source of income, enabling his later investments in energy and aerospace research.
Legal Disputes and Patent Enforcement
Major Lawsuits and Settlements
Lonnie Johnson has been involved in multiple patent infringement lawsuits against major toy manufacturers, including a high-profile case against Hasbro over unpaid royalties for the Super Soaker line. In 2013, a federal jury ruled in Johnson's favor and awarded him approximately $73 million in damages for breach of contract and patent infringement, according to court records and financial news reports Reuters. The case highlighted the importance of enforcing licensing agreements in the toy industry and drew attention to Johnson's role as both an inventor and a patent holder.
Johnson has also pursued legal action related to his energy technologies, asserting patents against companies he claims have used his inventions without proper licensing. These disputes often involve complex technical arguments about thermoelectric conversion and fluid mechanics, and they have been covered in both legal and business media. His willingness to enforce his patents has reinforced his reputation as a prolific and uncompromising inventor in multiple technology sectors SEC.
