Why was Gordon Gould's initial 1957 patent application suspended by the U.S. Patent Office?

Answer

Public disclosure of the concept before filing

The U.S. patent system includes a rule regarding public disclosure. If an inventor shares their invention publicly, such as through a lecture, before filing a formal application, it may disqualify them from receiving a patent. Because Gould gave a lecture at the Brookhaven National Laboratory months before his official filing, his application faced this legal obstacle.
