Product design is challenging: each 'hit' will have several 'misses', and dozens (hundreds?) of ideas that never make it even to a prototype stage.
As a chain 'geek', I have rooted through a number of chainsaw related patents, and am amazed at the things people have tried over the past 75 years.
Some do not 'work' when first released, but find a market later. E.g. saw chain with replaceable cutters, now used on some harvester chains.
The Intenz product is a great idea, and a step up from the spring-loaded tips, offered by one company, to address the chain tension problem.
If nobody tried to innovate, we would still be using stone axes.
