Kardashians Call for a Cease-fire in Name War With Blac Chyna

EXCLUSIVE

Blac Chyna got railroaded by the Kardashians' attorneys -- not the K sisters themselves -- in her effort to trademark herself as a member of the fam ... and now Kris Jenner's doing damage control.

Sources close to BC tell TMZ ... KimKourtney, and Khloe reached out to her and assured her their lawyers were following standard ops when they filed docs to block Chyna's application to trademark "Angela Renee Kardashian" -- not singling her out.

The assurances were necessary after the language the lawyers used. We broke the story ... the docs said all 3 sisters would "suffer damage including irreparable injury to their reputation and goodwill" if Chyna got the green light to use the Kardashian name in entertainment.

We're told Kris personally told Chyna there's no beef ... it was a simple mix-up and she's calling off the legal eagles. For now, everyone's saying the right things to make Chyna feel better about the legal diss -- but, fact is, her trademark still hasn't been approved.

Until it is ... it's a lot of lip service.
