Insurance technology company Lemonade Inc. is suing German insurance company One Versicherung AG and parent entity wefox Group for allegedly reverse engineering its app and website.

The lawsuit filed in U.S. District Court in the Southern District of New York claimed that the defendants, which include wefox Group founder Julian Teicke, accessed the Lemonade app and website to copy and extract the content in order to create their ONE app.

Teicke allegedly registered for insurance on the Lemonade app using various names and addresses, some of which were fictitious, and filed false claims.

According to the complaint, Teicke's policy was cancelled after he initiated seven claim requests in 20 days. Other wefox Group executives also allegedly filed false claims.

Lemonade said it wrote to the defendants multiple times asking them to stop their activity, but those requests were ignored.

The defendants are accused of copyright infringement, breach of contract and violations of the Computer Fraud and Abuse Act.

Lemonade is seeking permanent injunctive relief and damages, among other things. A wefox Group representative did not immediately respond to a request for comment.
