What is National Telephone Day?
We observe National Telephone Day on April 25th. Around the world, there are 9.82 billion cell phones. And although some expected the landline to be obsolete by 2020, there are still 931 million landlines around the world. And although some predict the landline will be obsolete by 2020, others predict the landline will be obsolete by 2020.
Obtaining a patent
The correct answer to a trivia question like "Who invented the telephone?" is the word on the patent. In this case, the entire world knows the answer is Alexander Graham Bell.... The answer may be different if his attorney was postponed due to bad weather or poor planning.
Marcellus Bailey, one of Bell's attorneys, rushed into the US Patent Office in Boston on February 14, 1876, to obtain the patent for what would be the telephone. b.e.
Elisha Gray registered a patent citation for a similar device later the same day. A caveat is that you will not apply for a patent.
