1. Tesla could’ve beaten Marconi to transmit long distance radio signals but his lab burnt down. Tesla’s own basic radio patent in US was filed a year after Marconi’s patent was filed in UK. Marconi’s US patents were repeatedly rejected but Tesla was granted radio patent in 1900.
2. In 1900 Marconi’s Wireless Telegraph company began thriving on the stock markets (went from $3 to $22) due to his family’s connections with English aristocracy and he became internationally acclaimed. Edison (Marconi’s consulting engineer) and Carnegie invested in him.
3. In 1901, Marconi for the first time transmitted and received signals across the Atlantic Ocean and Tesla calmly remarked, “Marconi is a good fellow. Let him continue. He is using 17 of my patents.” Tesla’s confidence was soon shattered.
4. In 1904, the US Patent office suddenly reversed its decision and gave Marconi a patent for invention of radio. Reasons for this were never fully explained but Edison and Carnegie and other powerful financial backing for Marconi was offered as one possible explanation.
5. Tesla was mired in other problems at the time, but when Marconi won the Nobel Prize in 1911, Tesla was furious and sued the Marconi Company for infringement but was in no financial condition to litigate a case against a major corporation.
6. It wasn’t until 1943 - few months after Tesla’s death - that US Supreme Court upheld Tesla’s radio patent. The court had a clever reason for doing so - Marconi was suing US government for use of its patents in WW1, and the SCOTUS avoided action by restoring Tesla’s patents!
