You’ll LOVE These Historic Patents of February!

Feb 13, 2023

February isn’t just the month of love. For many, it has also been the month of invention. In fact, February 11 is actually National Inventors’ Day!

Many inventors have seen their patents granted in February, allowing them to move forward with their inventions and change the world as we know it. Here are a few of the patents for inventions you might recognize — all of which were patented in February.

Digital Voicemail

Today, cell phones and voicemail are all an everyday part of our lives. This was not the case in the 1980s. Cell phones themselves had only been invented a decade before, and they were still the large, blocky devices that offered very limited time to talk before they needed to charge again.

On February 1, 1983, however, Gordon Matthews, Thomas Tansil, and Michael Fannin were granted a patent that made cell phones a little more like the inventions we know today. Digital voicemail.

This invention allowed for recorded messages to be stored in the phone’s database and retrieved and played later. Now, 40 years later, people still tend to fall into playing phone tag, but at least voicemails can help them know what they missed.

Dual-Vent Windows

On February 2, 1965, Alfonso Alvarez was granted his patent for dual-vent windows. These windows offered better ventilation by having two moving sashes instead of one, as well as a central sash control in the middle of the window that could lock or unlock the sashes.

Although the patent referred to these as dual-vent windows, we mostly know them today as double hung windows. These are the most common windows you’ll find in most American households.


This is one of the famous inventions that most of us learned about in school. In fact, of all of Thomas Edison’s inventions, the phonograph was reportedly his favorite. With a patent granted on February 19, 1878, Thomas Edison became known for the invention of a machine that could capture a sound and play it back.

By this point, Edison had lost most of his hearing himself. However, the phonograph set the precedent for recording devices of the future, including modern music players.
