In another thread, a member asked for info on the patent numbers pertaining to lasering on denim. This has come up a few times in the past so I thought I'd put in in a new location so it can be found easier if anyone wishes to review the patents. The validity of the patents has been debated here a few times before; I do not want to rehash that again but this info is for provided for reference and research.

The main patent holder seems to be a company called TechnoLines LLC. They have 3 subsidiary companies listed. The one pertaining to laser marking on denim is called TechnoBlast LLC. (However, at least one of the patents is general and discusses lasering on just about every common fabric, including synthetics and leather.)


The patents TechnoLines owns are found here:

The patents themselves are not easy reading.

Most of the patents show Darryl Costin as the inventor. He also appears to be CEO of TechnoLines.

Here is an article about the company:

So basically we are infringing on his patents. Luckly I live in Canada, and his Patents don't apply here. :D
