Copyright issues if using vector art from Shutterstock?
Perhaps you failed to notice "Copyright: PureSolution" on the Shutterstock page.
In 99% of all cases you can not trademark or copyright royalty free artwork.
What you "purchased" was the right to use the artwork in a limited fashion not ownership of the image. You should read the agreement for any stock image service you are using. Reading the Shutterstock agreement (http://www.shutterstock.com/licensing.mhtml) would inform you that you do not own the image or have any legal claim to said image.
So, short answer, No, you can not trademark or copyright an image from a stock image service.
Part II of the Terms of Service states
YOU MAY NOT:
- Use any Image (in whole or in part) as a trademark, service mark, logo, or other indication of origin, or as part thereof, or to otherwise endorse or imply the endorsement of any goods and/or services.
The license comparison page states the following:
What is not allowed with Shutterstock Licenses?

Italic emphasis mine. So this usage is actually explicitly disallowed.
