Easter for Eggheads

Posted on by

In a St. Patrick’s Day blog, the use of a common shape (in this case the shamrock) as a descriptive term in a patent was explored. In this Easter post, the use of another common shape, the egg is explored. There are multiple ways of describing as being egg-shaped, the most obvious being “egg-shaped” but three other options are: ovoid, ovate, and oviform. The most popular of these is “ovate” found in the descriptions in 19241 patents, and in the claims of 386 patents.
