Prior Art On Trucks?
Does no one else remember the way that trucks used to have name boards on the cab which were brightened up using 'Solar Radiation', (or light to anyone who cares)?
Now let me see, that was considered old hat back in the early '50s and I well remember it being discussed in comics, (or 'children's papers') or the like back then.
Can I please have a patent for recycling any old idea that has fallen out of use due to easier methods being adopted by technology lovers who cannot believe easy solutions?
The ONLY patentable aspect is that it is so adjectivally obvious that no one believed that it was worthy of a patent.
