[QuadList] RCA BROADCAST NEWS issues for free online viewing

[C. Park Seward]

Hi Bill,

You may want to check that fact. He was the only person who had RCA write him a check for using his television parents. It was said the RCA lawyer had tears in his eyes when presenting the check.

"In 1931, David Sarnoff of RCA offered to buy Farnsworth's patents for $100,000 (USD), with the stipulation that he become an employee of RCA, but Farnsworth refused.[25] In June of that year, Farnsworth joined the Philco company and moved toPhiladelphia along with his wife and two children.[26] RCA would later file an interference suit against Farnsworth, claiming Zworykin's 1923 patent had priority over Farnsworth's design, despite the fact it could present no evidence that Zworykin had actually produced a functioning transmitter tube before 1931. Farnsworth had lost two interference claims to Zworykin in 1928, but this time he prevailed and the U.S. Patent Office rendered a decision in 1934 awarding priority of the invention of the image dissector to Farnsworth. RCA lost a subsequent appeal, but litigation over a variety of issues continued for several years with Sarnoff finally agreeing to pay Farnsworth royalties"

In the late thirties, when RCA and Zworykin, who was now working for RCA, tried to claim rights to the essence of television, it became evident that Farnsworth held the priority patent in the technology. The president of RCA sought to control television the same way that they controlled radio and vowed that, “RCA earns royalties, it does not pay them,” and a 50 million dollar legal battle subsequently ensued. 

In the height of the legal battle for patent priority, Farnsworth’s high school science teacher was subpoenaed and traveled to Washington to testify that as a 14 year old, Farnsworth had shared his ideas of his television scanning tube with his teacher. 

With patent priority status ruled in favor of Farnsworth, RCA for the first time in its history, began paying royalties for television in 1939.
