In the spring of 2013 GL&V sued three former employees and their newly formed company C Inventing AB as well as the company's representative for patent infringement. In the lawsuit for the patent case GL&V pointed out to the defendants that they had used GL&V proprietary mixing technology for their own benefit.
GL&V also sued the former employees at the Labor Court for having violated the Duty of Loyalty to the employer and during their employment engaged in a competing business through their company C Inventing AB.
The defendants denied patent infringement and filed an opposition to the validity of GL&V's patent. The former employees claimed that they had not breached the Duty of Loyalty in their employment.
The parties have subsequently reached a settlement.
In the settlement it has been clarified that the defendants admit that GL&V has patent protection against the defendants’ manufacturing and selling GL&V’s proprietary mixing technology to a Swedish pulp & paper mill. The former employees also in the labor dispute admitted that they breached the Duty of Loyalty under the current collective bargaining agreement. The defendants have also agreed to a payment to GL&V as a financial settlement of both cases.
