Can't successfully sue a job title in the US either. Plaintiff needs to list a real person or legal entity (i.e. corporation, LLC, Trust, etc) by name.
If he doesn't know this info, he can use fictitious names such as JOHN DOES 1-10 and ROES CORPORATIONS 1-10. In the writeup, he would say these people/companies will be named later as their true identities are uncovered. Unless the plaintiff sues a real person or legal entity, there won't be a binding judgment.
Apparently, the legal system in your country is way different than ours. So, it's not surprising you have a hard time understanding the way things work in the US.
