Those "papers" do represent actual inventions, no matter how condescendingly you say the word "papers". And inventions only a handful of years old at that.
I'd venture a guess that many of AT&Ts inventions were (or would be, given a wider audience like we have today) looked down upon in a similar way - there were probably people who said "Ha! A toy like that? A couple of screws and some silly wires? We've already got _____ that can get that done, that clunky thing will never be practical."

Then again, I also think its a good thing that with more resources at our disposal we can take such a critical eye to work being produced by capitalistic companies, and as practices and inventions enter the industry, more easily take them for what they are really worth.
