Thank you for sharing.

Went to a link in the comments and found that the name "Pentax is protected there till 30.09.2022. Hope, Ricoh hat this date in mind and will take steps to prolong their reiht to use the name, exclusvely.

Here the entry in the database:

Best regards


Very interesting, because that "Pentax" patent belongs to Hoya, as they still make optical instruments under the name of Pentax. Whether there is another patent for the name Pentax registered by Ricoh, we have no clue. Maybe one day will Hoya bring Ricoh to court for violating the use of the Pentax name.

My understanding is that Ricoh has a license from Hoya to use "Pentax" for the use with cameras ans similar optics (e.g., binoculars). There is some discussion on whether the license is time limited or not.

In addition to medical instruments (endoscopes) the Pentax name has been used on surveying equipment.  Not sure if they are still under production or not.
