to get more clear
As TreeCo says, "climbing trees on 100% srt. We know it is coming...... and the pioneers in the field are emerging........."
A more versatile device would allow you to climb SRT, DbRT, DdRT, would be quick-on, quick-off and would allow you interchangability between climbing systems in any given moment. You would be able to do mid-air changeovers from ascent to descent, and descent back to ascent. It can be used left-handed or right. The device would be simple, easy to use, easy to learn and not cost a fortune.
Let's say, hypothetically
, that a climber/inventor has been using and refining this device for ten years, field-testing it daily, photodocumenting it from it's inception, networking with companies like Petzl, DMM, CMI, USHBA, Kong and Black Diamond under contracts of non-disclosure to assess it's feasability for production. In other words, he's done his homework, has done his research and has spent thousands in R and D, prototypes, photography and art.
He's excited about it for the world of arboriculture. He shares it one day on open forum, a skank sees his opportunity to develop and produce the idea, mildly different than the original, throws a pat pend on it because his sister in-law is is an Intellectual Property Attorney, he's now in ownership of the climber's idea and is going to market with it. The only recourse is with money and lawyers.
Do you see, Brian, what you're asking for?
