You kind of stumped me at first, didn’t think you were referencing Marconi. I was almost ready to give in, but then I went looking for that court judgment. I believe it’s this one. Lemme just quote you one fragment of the attached opinion:

Marconi’s reputation as the man who first achieved successful radio transmission rests on his original patent, which became reissue No. 11,913, and which is not here in question. That reputation, however well deserved, does not entitle him to a patent for every later improvement which he claims in the radio field.

It seems like this case wasn’t about his original patent whatsoever, only his later claimed improvement to it. Yes, the later one was invalidated, but the original was not. And it also looks like they focus more on patents of Stone and Lodge, only sporadically mentioning Tesla. They even state that wireless communication wasn’t even the primary purpose of the Tesla aparatus, it was actually for his wireless energy stuff, altough he did mention it could be used for that.

So I stand by my opinion. Marconi didn’t really screw over Tesla, altough it seems he did screw over Stone and Lodge.

Altough I admit I might be wrong, it’s very hard to look up anything on Tesla and get objective results. Also, after spending an hour reading a 70 year old court case about patent infringment I decided I should probably find something better to do with my time and can’t be fucking bothered anymore.
