Coffee Maker Patents

The right that the government grants an inventor to ensure that no one else replicates and sells their invention is known as a patent. Patents remain valid for 20 years after an application is filed, and patent rights become enforceable once the U.S. Patent and Trademark Office (USPTO) approves a patent. In order to be patented, an invention must specifically be not obvious, novel and useful.

This was the case when the first coffee maker was first patented. Including the very first one, there have been numerous coffee maker patents, such as the ones below.

A History Of Coffee Maker Patents

= While not exactly a coffee maker patent, the German scientist Ludwig Roselius invented the coffee decaffeination process in 1906 as an alternative to caffeinated coffee. His process involved the use of a “supercritical fluid” for the removal of “coffee wax” from unroasted coffee. An absorbent, which was precharged with pure caffeine, would then absorb that coffee wax.

= The first coffee maker with a filter was invented by Melitta Bentz on January 1st, 1908. Unlike the cloth and linen filters from the past, she used blotting paper to construct the filter.

= On January 1st, 1929, the first French Press Brewer was invented. The brewer has a container into which coffee grounds are placed, followed by boiling water. The container is also attached to a mesh screen. Once the coffee is brewed, a “plunger” is pushed into the container, causing the mesh screen to push the coffee grounds to the bottom and hold them there. As a result, the coffee obtained is free of the grounds.

= Faema, which is a renowned brand of commercial coffee machines, was the first invent a Pump Espresso Machine. If you have ever reviewed commercial espresso machines, you are probably aware that instead of manual force, they use a motor-driven pump to brew the coffee.

= Mr. Coffee was the brand that invented the first Atomic Dip Coffee Maker. The water that is poured in along with the coffee beans gets heated automatically, brewing the coffee and keeping it heated longer. There was a time when only restaurants would have atomic drip coffee makers, but today, you may even purchase one for your home.

= Over the recent years, many brands have introduced different versions of the K-Cup coffee brewing system, which is similar to an automatic coffee maker. Of course, this revolutionary system got its name from Keurig, the brand that invented it. K-Cups are small cup-like packets that contain enough coffee grounds for a single serving of coffee, which are brewed in the K-Cup system. Once a K-Cup is placed in the system and it is closed, a hole is pierced all the way through the K-Cup. Hot water that is poured into the machine beforehand is then poured into the cup and the brewed coffee can be collected into a mug below.


Of course, there have been numerous other coffee maker patents that have been filed over the years. However, when it comes to the history of coffee maker patents, these were the most landmark ones, which were milestones that were crossed in order to get to modern day coffee brewing.
