Anyone can be bankrupted by corporations over literally any bullshit claim. They can afford to lose in court and still win because their objective never was to win in the first place, it was to burn your money through legal fees. It's essentially abuse of the legal system by the rich to keep the poors in line.

Big companies with deep pockets will even bankrupt other companies this way. For an example, look at how Sony sued playstation emulator companies over the most bullshit claims possible, got an injunction, killed their profits and then it didn't matter that they lost in court afterwards. In my country, the judge would have estimated the profits the smaller player lost as a result of Sony's frivolous lawsuit and forced them to pay it all back on top of the legal fees.
