在加剧争议的情况下，两个芝加哥地区的窗帘壁系统供应商正在交易诉讼。Reflection Window和Glass提起的最新诉讼称，竞争公司的所有者Kurt Levan提出了虚假的广告索赔 - 对伊利诺伊州的消费者欺诈和欺骗性贸易惯例的侵害。

The latest lawsuit was filed in July in federal court in Chicago by反射against LeVan andTalon Wall Holdings，，，，Chicago Heights Glass GroupandEnTekk Group，他拥有三家公司。该诉讼称，“列万公司和爪式挂牌被许可人在芝加哥，纽约，纽约，丹佛和其他地方销售，推广和出售了Talon墙，并在窗帘壁上的消防鸿沟中安装了任何防火材料。”

Back in January, LeVan filed suit alleging Reflection had created a knock-off of its window-wall system, based on a former LeVan employee’s knowledge, and had installed the system on several construction projects.

反思诉讼还声称，这些公司“实质上是虚假和误导的商业代表性来赢得有利可图的建筑合同，包括吹捧自己的爪子墙产品作为满足适用的火灾安全标准，并知道这种代表是不真实的，可能会误解，欺骗和欺骗和欺骗和欺骗和/或导致物质伤害。”

列万反过来声称，反思诉讼是对他在一月份提起的诉讼进行报复。它声称芝加哥Heights Glass的前业务发展副总裁Joel J. Phelps于2020年6月离开公司，并随身携带了与Talon Wall Systems有关的机密信息。他被首席运营官的反思雇用。

“Phelps’ unique knowledge of Talon Wall’s most confidential information—in particular, the effectiveness of the Talon Wall and certain nonpublic trade system improvements to the Talon Wall System—was one of the primary reasons that Phelps was hired by Reflection Window & Wall," says the complaint.

原告还声称，菲尔普斯没有将材料返回芝加哥高地玻璃，他有义务根据分离协议返回。

'A Very Serious Counterattack'

“It is a very serious counterattack that we think was filed in response to a trademark and patent infringement action that we have in place with that company since earlier this year,” LeVan says.

In its legal action, Reflection claims it lost more than $13 million in bids to LeVan's companies, due to LeVan's companies misrepresenting and exaggerating the efficacy of the Talon Wall system.

George Spathis, an attorney for Reflection, asserts Reflection has devised a way to pack the void of its notched curtain wall system, the U8000, with a material to deter fire.

他说：“他们有一名消防安全专家（一个建筑项目），并用矿物质羊毛填充了非常精确的规格。”“如果您的包装太密集，它实际上会变得更加易燃，如果您的包装太松散，您会留出太多空间，无法进行热气体。”

Spathis says their curtain walls are installed in segments and the mineral wool is packed at each different stage.

他补充说，反思工作了六个月，并花费了数十万美元才能公开列出其流程，这意味着由独立实验室对其进行审查，这些实验室证明它在该领域是可复制的。

Spathis说：“这是消防安全的巅峰之作，我们认为，这给了我们竞争优势，这就是我们试图保护的东西。”

反思还声称，莱万向他们的一个工作人员派遣了一份间谍，以查看他们的过程并试图复制它。

“Because Talon Wall has a shelf that actually prevents you from looking down [into the void] and actually getting in there," they can’t replicate Reflection's process, he claims. “They have tried to replicate it. But they can’t.”

反思还指出，在其响应迅速的法律诉讼中，列万将其产品呈现为“同行审查”，但尚未完成公开列出的过程。

列万否认他的公司从事任何虚假实践，并表示其产品是安全的。他将反思称为“诽谤性”和“完全不真实”。

“我们有书面记录,书面表示and written statements from engineers [stating] that everything we’ve provided has been completely safe, completely tested, has met all current guidelines, all current industry standards and is not a risk to any occupancy,” he says.

Talon Wall Holdings拥有其系统的所有专利，该诉讼国家是由Levan发明的。

LeVan’s original lawsuit against Reflection has not yet been resolved.
