The problem is that patent cases are intrinsically prohibitively expensive. It's the nature of them, not a result of some recent regulatory change advocated by Google. Especially when there are companies that hold many thousands of patents, any of which can be claimed in combination and cause the defense to incur significant costs even if the claims or their applicability ultimately turn out to be bunk. And you're bankrupt before you can prove it.
The result is that large companies can destroy small practicing inventors with legal fees at will, which is naturally what they do if the small practicing inventor attempts to assert their patent.
To avoid this is to not practice your own invention so you can't yourself be sued for infringement. Which implies that the patent system is only useful to trolls and large incumbents and is actively harmful to small practicing inventors, who can't usefully assert their own patents against the incumbents but can have the large incumbents assert their patents against the small inventor.
Some more detail: during bankruptcy, anyone that had business with the company can either file an adversary proceeding (essentially a lawsuit within bankruptcy court), and/or can do depositions/discovery (2004 examinations). They can also buys assets of the defunct company as well as legal claims to go after the company officers. Then after bankruptcy they can try to use whatever information, assets and claims they acquired, to sue the company officials personally.
What on Earth could make someone so angry to go through the hassle of doing this?
Make sure to stay away from assholes and never sign a contract that says you (your company), will cover the other party's legal expenses.
Whatever the case, I wish you luck.
