That's a separate issue. If Huawei violated some IP patents then why aren't they suing for that? Any meaningful R&D developments would be patented and would be publicly available and described anyways.

And if your product is so weakly innovative that a picture of the circuity or some power point slides basically give away significant trade secrets, then your product probably sucks.

These charges sound like they're for non-innovation based trade secrets, whatever those may be.
