Bell were first because they didn't have a big stock of Germanium. The issue was purity. Each time the guys in Bell ordered it, it was purer.
The idea of transistors goes back to the late 1890s and purity was the problem. Valves proved easy and cheap to do. Still cheaper than transistors in 1954 and EB91 was cheaper than 2 x 1N34 or 1N60 etc.
Westinghouse in France thought they were first because Bell delayed publishing. They used Germanium from diodes recovered from munitions!
The USPTO is totally broken since the time of Edison. They hardly do due diligence. They are paid more for approvals than rejections and their theory is that anyone objecting can take a court case, which benefits USA companies and the richest corporations.
Who was the Russian that worked on LEDs and transistor theory but died at Stalingrad's Siege?
However the early point contact device wasn't commercially viable.
