Edit:
AI can be a great help here, ask it:
- How to prepare your case for your country.
- Where to file and how much it going to cost.
- Help you find weaknesses in your case and what you can do to fix those.
- Rewrite your text in proper legalese (I do recommend to prepare the your arguments yourself to avoid over generalization from an LLM).
Of course you need to verify because of hallucinations but showing up is half the battle here. Big (tech) corps + internal bureaucracy makes it quite expensive for fight these cases. Especially if there are many different countries.
