The word HEMI is copywright. Same as GM & FoMoCo have name copywrights on products. Hemispherical is the mech. design description.Manufactures can have a Hemi [ hemispherical] by design, they just cant use the name!!
 HEMI is trademarked by FIAT Corp. If any other manufacturer use it on a product without FIAT Corp permission they will be most probably be sued. "Permission" is the key here, they hold the trademark so permission must be given from the owners-FIAT Corp.

 Look at any FIAT  Corp advertising and the words, Jeep,Challenger,Dodge,HEMI etc etc are trademarked. Dont confuse trademarked with design. The 429 may be of a somewhat hemispherical design, but it is not technically known as a HEMI and will never be known as one.Now if FoMoCo trademarked the  flathead as a HEMI back in the day, it may well be different! lol

 sms777, I think you may be forgetting the 6.1 and 5.7 Hemis and the Super Stock 392 concept car that made a limited build run in 0809. Fitted to a limited run 'production' vehicle. Although limited and built 'off the line', it was a limited 'factory' build just the same.Just like a GM dealer COPO or Shelby or Royal Bobcat build from the past

Well, you better get Chrysler onto these guys, because it doesn't say 'used with permission' anywhere.

Doesn't a patent only last for so long, then unless you renew it becomes usable.

I am aware of the 5.7 and 6.1 hemis and they quiet right to use the term Hemi since they own the copyright..... But....
Have you seen a pair of heads off a 5.7-6.1 hemi?

They are not what they seem .... are they?
