Callaway Golf has had a good week... their players dominate the field on Sunday and they are awarded 2 golf ball patents and 1 golf club patent on Tuesday.

Callaway was issued USPN 7,179,175 titled “Golf Club Having Stepped Grooves.” The ‘175 patent is definitely worth reading… it is short and it illustrates that broad patents issue to inventors that come up with inventions that are the first in their field. The figure below illustrates the “stepped groove” concept.

Next, Callaway was issued USPN 7,179,177 titled “Golf Ball With Covered Dimples.” The ‘177 patent is another broad patent that is fascinating reading. The figure below is a cross-section of a portion of a dimple and illustrates the overhang that is covered by the patent. How do they come up with this stuff?

Lastly, Callaway was issued USPN 7,179,178 titled “Golf Ball Dimple Pattern.” The ‘178 patent isn’t as interesting as the ‘175 and ‘177 patents, but reading it will make you appreciate the amount of research going into golf technology.

Congratulations Callaway on one heck of a week.
