That is not necessarily true at all. When one does their due diligence before buying a company, they also have a clause in the purchase agreement indemnifying them from things they should have been told about but were not. No company buys another companies lawsuits on purpose and knowingly like that. It just doesn't happen. Buying another company's debt? Sure, that may be different, but not lawsuits that could put them out of business.
