Why Do Designers Put Their Logos on Bags?

Hi Darlings:

The answer to the question above is because fashion designs are not protected by IP law however logos are via Trademark law. Don't despair the idea or rather the fight for IP protection for Fashion Designs has been debated by many for a very long time. Finally, Congress is taking note.

So,while the Divas are strutting down the runways and other designers are taking their bows in Milan, Narciso Rodriguez was in Washington, DC this week to testify on behalf of the Council for Fashion Designers of America before the US House of Representatives Committee on the Judiciary. HR 5055 is finally before the House the true question is whether or not it will be passed. If the law as narrowly tailored as it is becomes part of Copyright law fashion designers may finally have legal recourse.

Here are some other articles and testimonies on the issue.
