Kim Kardashian's Company Sued for $100 Million, Accused of Jacking the Technology Behind LuMee (UPDATE)

4:23 PM PT -- A rep for the Kardashians tells TMZ, "The patent lawsuit filed by Snap Light has no merit and is just another attempted shakedown. Kim has done absolutely nothing wrong."

A rep for LuMee tells us the lawsuit has no merit and Kim did nothing wrong. The rep added, "LuMee is an innovator of illuminated cell phone cases and was the first to market. Between its patents, copyrights and trademarks, LuMee has developed substantial intellectual property rights surrounding its product line. LuMee is currently asserting patent infringement against Snaplight.”

Kim Kardashian's use and promotion of an illuminated smartphone case is totally ripping off the guy who invented it, and he says he has receipts to prove it ... according to a $100 million lawsuit.

Kim's company ... Kimsaprincess, Inc. got slapped with the suit Monday -- a guy named Hooshmand Harooni says he got a patent back in 2013 for an "integrated lighting accessory and case for a mobile phone device." If that sounds familiar, that's because it's a perfect description of the LuMee.

No doubt you've seen Kim flaunt the LuMee on her social media. She says it helps her take perfectly lit selfies -- obviously, a major asset in her world. She even used it for her famous selfies with Hillary Clinton.

Problem is ... Harooni licensed his invention to a company called Snaplight, which is now getting buried in sales. Snaplight and Harooni say LuMee jacked their patented technology, and made it an unfair fight by teaming up with a supreme trendsetter like Kim.

In the docs, Snaplight says Kim is getting a cut of LuMee's sizable profits -- and now it wants a chunk of that cheddar too. The company says $100 million will cover its lost profits.
