They keep trying and that is a good sign for PTOI investors!

By far, most inventions are improvements upon other known devices or solutions. In fact, whenever I teach patent law courses I tell students that in their career as a patent attorney they are unlikely to ever come across a pioneering invention (i.e., first of its kind, revolutionary invention). Even the great Thomas Edison, the most prolific inventor in US history, rarely came up with pioneering inventions. What Edison really had a knack for was taking something that someone else had come up with and making it extraordinarily better.

For example, perhaps Edison’s most famous invention was the light-bulb. Truth be told, however, Edison didn’t really “invent” the light-bulb. Edison significantly improved upon the technology by developing a light-bulb that used a lower current electricity, a small carbonized filament, and an improved vacuum inside the globe. Edison’s invention lead to a reliable, long-lasting source of light. Prior to Edison’s invention light-bulbs lasted only a few hours, but after Edison’s improvement light-bulbs could last 50 to 60 days, making them practical for the firs time. So it is entirely fair to say that Thomas Edison invented the first commercially useful light-bulb, which was an improvement on previously existing light-bulbs.

Hopefully the Canadian Patent will give them some leverage
