"Any party that fails to meet a condition under subsection (a)(3) shall be required to post a bond in an amount determined by the court to cover the recovery of full costs." [1]
The subsection (a)(3) reference points to the subsection (d) exemptions for original inventors, parties which have made "substantial investment" in exploiting the patent through "production or sale of an item covered by the patent", universities, and technology transfer organisations "whose primary purpose is to facilitate the commercialisation of technology developed by one or more institutions of higher education".

Any judge worth his salt would either sanction the hell out of the lawyers involved, or let you go after the parents.
LLC is limits liability doesn't it? Its not no liability. Surely a more effective and wide ranging measure would be to enforce limits on the limitations. If no one wants to take some small amount of responsibility for a company, that company has no business existing.
A coworker had his house destroyed by errors on an adjacent building site, and he faces the real risk of the real estate guys declaring a loss on this one and moving on to the next "shell company".
Either that, or mandatory insurance for these cases.
It's just unfair that someone is made homeless and faces the threat of being left out in the cold while the persons responsible are raking massive profits elsewhere. It's not a faceless meteorite crash, it was gross negligence.
I can't find the news in English, but:

In the case of patent trolls, "piercing the veil" is also complicated.
There's also the common practice of naming a figurehead as the person responsible for a company, while the real owners don't figure in the legal documents (we call them "testaferros" over here). I don't know what the solution is (I wish I did), but the current system doesn't seem to be working out well.
In the case of the shell companies the owner is the parent company, not the shareholders. Thus the shell companies limit the liability to the parent company. This allows the parent company to sue people without the risk of an adverse ruling.
