Is the brand “marina militare” under panerai patented?

i just want to know if the word “marina militare” which appears on panerai watches are patented or copyrighted. If yes, please paste me some reference link to read up more. I cant find any relevant info on panerai’s patented / trademark items except for its winding crown and “luminor”, “radiomir”. How about “marina militare”?? Thanks in advance

The first “Marina Militare” was launched a short time after world war II for the Italian Military Marines and is one of the most special timepieces developed by Panerai.
The watch based on a former “Radomir”.
One item of MM is presented in the Panerai museum.

The new “Marina Militare” is a replica of the old one but with cheaper materials.
I am informed that the replica is limited to 1950 pieces.

May be that the original MM have had a copyright by Panerai or by the Italian Navy.
I found nothing about.
Same with the replica.
