MARUMAN PATENTS

The start was always from Maruman

In 1974, Maruman started the development of the golf clubs based on the metal mold manufacturing technology learned from our experienced lighter productions, and announced innovative carbon shaft "PARSEC ".
At that time, domestic market totally relied on imports. However, Maruman has been engaged in developing domestic golf club futuristically.
It was believed that the golf clubs were made of persimmon trees.
Maruman completely broke down this widely believed concept, and announced the first metal wood series "Dangan" in Japan.
It was treated as heresy at the time. But now, it becomes mainstream of golf clubs

 

"DANGAN" acquired the first patent for golf club development.

Since Maruman took out the first patent at the same time as the announcement of the first metal head "DANGAN" in 1980's, Maruman has continued to acquire a lot of patents. And we are now applying for a patent for the technology that reflects nano-technology.

 

Explaining the brain of Maruman intellectual golfing relates with the science technology

IThe think tank of Maruman ~Do science for intellectual golf ~
Maruman's development team staffs have a high reputation for technology rivaling world famous manufacturers.
What make it possible are not only academism but also our spirit of making products to break through conventional concepts and to create practical value.
Since our first patent, we have promoted the management of intellectual property aggressively in this field of business.
As a result, we have already acquired a group of patents.
