The vacuum flask was invented by Scottish physicist and chemist Sir James Dewar in 1892 and is sometimes referred to as a Dewar flask after its inventor. This invention wasn’t implemented for commercial use until a German company, Thermos GmbH, was founded in 1904. Unfortunately for Dewar, he failed to ever register a patent for his invention, and Thermos patented it instead, effectively stealing his design and having it protected under law. Dewar wound up eventually losing a court case in claiming the rights to the invention.

Even though “Thermos” remains a registered trademark in some countries, it was declared a generalized trademark in the U.S. in 1963. Again, an example of a brand becoming too well-known as the product itself.
