A civil dispute over patent details (which is basically business as usual in technology) is not the same thing as orchestrating a criminal corporate espionage ring to exfiltrate inside information.

One is arguing over the legal application of publicly filed information, the other is literal espionage, which not only impacts non-public trade secrets and insider (i.e. stock implications) information, but also raises questions about external agents secretly making actions that could undermine operations.

Nobody goes to prison for patent infringement, but you absolutely can for the latter.
