Ivanka Trump has been hit by a claim that she ripped off trademarked designs for her coat collection - the second copyright suit filed against the First Daughter in under a year.

Unicolors Inc., a California-based 'textile converter' of imported and domestic fabrics, is suing Trump's brand - Ivanka Trump Marks LLC, Gill Leather Fashions - a manufacturer of Trump's clothing line, and TJX - the umbrella retailer that owns TJ Maxx, which sold the coat in question.

In documents obtained exclusively by DailyMail.com, Unicolors claim that they own the rights to the 'unique two-dimensional graphic design' and that they provide samples to clients with the understanding that if purchased, the design will be reproduced as is.

Ivanka Trump is being sued for allegedly ripping off a California-based fabric company's designs to use for a coat in her collection sold by TJ Maxx

Unicolors claim that they own the rights to the 'unique two-dimensional graphic design' and that they provide samples to clients with the understanding that if purchased, the design will be reproduced as is

But the suit alleges that Ivanka did not purchase the sample and used the design for this coat, making minor changes to Unicolors' original design

The fabric manufacturer is demanding an injunction, ordering Ivanka to stop selling coat, and is suing for all profits made by stealing its design

They believe, however, that the both the First Daughter and Gill Leather Fashions accessed their sample and reproduced it with only minor changes for one of Ivanka's coats.

The suit reads: 'Defendant IVANKA TRUMP purchased, sold, marketed, advertised, manufactured, caused to be manufactured, imported and/or distributed fabric and/or garments comprised of fabric featuring a design which is identical, or substantially similar to, the Subject Design. '

It goes on to explain that Ivanka's clothing is distributed by ten different retailers and is usually displayed and advertised differently than other clothing lines.

'Trump's clothing is often prominently displayed in a manner that is very easily accessible to customers and attracts their attention by displaying the 'Ivanka Trump' name on signs and other advertisements near its clothing.'

It also alleges that as retailers prefer to have the 'Trump name' attached to their clothing, the 'copyright infringement' is costing Unicolors significant business.

The fabric manufacturer is demanding an injunction, ordering Ivanka to stop selling the coat, and is suing for all profits made by stealing its design.

Ivanaka has yet to respond to the lawsuit and is currently in the throes of a separate legal battle, in which she was accused of ripping off designs by the high-end shoe designer Aquazzura.

Unicolors is also suing the coat's manufacturer, Gill Leather Fashions and TJX - the umbrella retailer that owns TJ Maxx

Last year in June, the fashion designer's business filed a federal lawsuit against Ivanka and her licensing company.

It claimed Ivanka's Hettie stiletto was identical to their Wild Thing pump, which has found a following among celebrities including Kendall Jenner and Solange Knowles.

The Italian shoe company pointed out in their complaint that the color, silhouette and fringing design of Ivanka's closely matched their own.

The company is demanding an injunction be issued against Ivanka, as well as accounting for all profits made from the shoes they believe were ripped off.

Matthew Burris, the CFO of Ivanka's licensing company, released a statement after the lawsuit was filed stating: 'This is a baseless lawsuit aimed at generating publicity.

'The shoe in question is representative of a trending fashion style, is not subject to intellectual property law protection and there are similar styles made by several major brands.'

Ivanka is now demanding that the court dismiss Aquazzura's case and pay for her legal costs.

In January, the First Daughter officially stepped down from her role at her eponymous fashion line.

In a statement, she wrote: 'When my father takes office as the 45th President of the United States of America, I will take a formal leave of absence from The Trump Organization and my eponymous apparel and accessories brand. I will no longer be involved with the management or operations of either company.'
