Complicated subject. I am a manufacturer that produces licensed, Branded and private label products. Not for Porsche. The difference comes down to quality standards and build specification. There is a difference, sometimes minor w/ little variability from the gold standard. There are other times when the difference is major yet the appearance is identical.

In my business,
Branded or OEM would be built to Porsche specification by or for Porsche. Branded parts should have the branded codes and markings. This ultimately means Porsche stands behind the part.

Private Label would be produced or replicated by a competing or independent entity to duplicate the branded part. The tangible difference would be the part would not be built using the branded specifications. Again quality could be equal or better.

Licensed normally is the licensee's spec w/ the brands approval. This isn't the gospel.

There was also an issue w/ goods produced in China. A patent / trademark attorney could provide the legal aspects.
