Series Features: One-touch press ignites with automatic cap release and friction ignition; releases to extinguish.

Patent Background (Grant and Amendment Application): Background: The absolute patent dominance of the fully automatic "one-motion" lighter belongs to Ronson, which secured the Banjo patent in 1926.

Any brand using a one-touch, fully automatic press machine manufactured in the US will face strong legal action from Lanson.

Evans' approach: In the 1930s, Evans was sued for patent infringement by Ronson over a similar design.

Afterward, Evans adopted a dual-track strategy: paying Ronson royalties (licensing) and incorporating micro-markings like "Under Ronson Pat." on its fully automatic lighters' bodies. Simultaneously, Evans engineers developed the "Trig-A-Lite" side-trigger drop-action mechanism and the post-war Spitfire (later renamed Banner) roller-drive fully automatic mechanism. By altering spring tension direction and gear engagement points, they successfully secured their own patents for specific improvements, transitioning from full reliance on licensing to partial independent innovation.
