1. the USPTO grants lots of patents on the everyday engineering solutions that designers and engineers come up with to solve typical engineering challenges. this adds huge and unnecessary legal risks to firms creating and commercializing products.
2. patent law puts the burden on firms to determine whether their products infringe any patented concepts/implementations, yet most IP lawyers advise not doing any IP research before/during/after development and commercialization in order to to trigger 'willful infringement' provisions in current patent law.
3. even for firms that would like to find out before/during development how many dozens, hundreds, or thousands of aspects of their designs are already patented, there is no practical way to accomplish that goal now. Patents are written cryptically, using obscure legal language that can rarely be parsed even by the engineers who developed the ideas. Worse, there are no decent tools for efficiently finding patents in areas a firm might want to investigate. It is very unlikely that any US legislator or judge has a good grasp of how expensive in dollars and time it would be for a firm developing one product to fully vet the product for infringement before launching it.
4. the faulty filter at the USPTO creates a 'gladiator ring' dynamic for firms: even if they recognize the ethical and practical shortcomings of the patent system, if they want to survive they must fight in the ring. Fighting means (a) getting weapons (filing patent applications on anything and everything, and hoping some get granted whether they are non-obvious or not), and (b) using the weapons against the other gladiators in the ring (filing offensive litigation against other firms going about the business of developing and commercializing products). The gladiators would really rather not have to fight each other, but within the ring of business their weapons are only useful against each other, not Rome (the USPTO and inane circuit courts)
'facilitators' like IV will be a necessary evil to grease the skids of product development commercialization. Just as soon as our government stops granting monopoly rights to non-innovators, however, these guys are toast.
it would be an illuminating exercise to come up with a laundry list of obvious things that have been patented to show the extent of the issue.
as an aside, there is a population of web commenters who use lazy arguments about how companies 'steal' from other companies and 'freeload off other's R&D'. Nothing could be further from the truth in my experience - companies don't build products, product development teams composed of people create products, and rarely if ever do engineers and designers reverse engineer competing product software or services in order to copy implementation details. It would be an interesting study to try to track a truly novel idea that warrants a patent and follow the propagation of the idea through a population of engineers and designers that operate in the relevant domain, to validate whether people rip off competing products, or if not, how design patterns emerge from industry.
