I'm fairly pro patent, but I disagree. Unlike copyright where there is an almost unlimited amount of expression available, some inventions are just something people would independently come up with.
Nobody would organically and independently come up with Mickey Mouse or Sherlock Holmes.
But different teams would have invented the BJT transistor if Bardeen, et al. never existed.
Patents length acknowledges that by not giving exclusive rights forever. It's more of a challenge prize than a pure ownership of the idea indefinitely.
But that's an interesting idea. In that system how is the valuation of an innovation determined?
This way big pharmaceuticals put a couple million into a new drug and they get to profit for a few years. An Apple engineer makes slide to unlock in a couple days and given the number of iphones sold the patent is over quite quickly.
tl;dr a salary cap for patents based on R&D cost
First copyright is always a life long idea, but the focus of patents have always been to incentivice long term research efforts that have budget constraint by having a mid-term monopoly
problem today: a lot of trivial design-patents and even patents that are used in the wars between big corps. as one of my advisor board state - screw that patent, we cannot defend it anyway Behind a lot of those patents there is no research in the sense but it rather came out of "usual" engineering.
i think that the proof of non-trivial has to be a part of the application and is better suited than discussion about life-time - because patents could still have a strong point in basic-research
Problem is what to do with the already existing bogus patents - any suggestions?
Not true in the USA until Disney started twisting the law. This idea has a longer history in Europe.
