Cooking Mama IP owner sues Planet Entertainment over sale of Cooking Mama: Cookstar

Mum Who Cooks: Cookstar

Remember the ongoing dispute between Cooking Mama: Publisher Cookstar Planet Entertainment and the rights holder of the Office Create series dating back to 2020? Well, in an update, Planet has been sued by Office Create.

There was actually a fallout between the two parties prior to the game’s 2020 release, but Planet Entertainment still went ahead and released the game worldwide in digital and physical form. Intellectual property owner Office Create issued an official statement at the time, calling it an “unauthorized release.”

It seems that the International Chamber of Commerce has finally sided with Office Create, acknowledging that the release of Cooking Mama: Cookstar violates intellectual property rights. Office Create is now looking to pull all remaining physical copies off the market. Apparently, the digital copies have already been removed from sale.

Here is the translation of the latest Office Create update, via its official website:

Thank you very much for your patronage of the “Cooking Mama” series.

As reported in April 2020, Planet Entertainment LLC (located in Connecticut, USA; hereinafter referred to as “Planet”) violated our license agreement and we released the Nintendo Switch version of Cooking Mama: Cookstar, which did not meet the standard quality, without our permission, and has set up sales operations in North America, Europe and Australia. Also, in the US and Europe, we started advertising the sale of the Sony PlayStation 4 version of “Cooking Mama: Cookstar”, which we didn’t allow in our license agreement in the first place. In response, on March 30, 2020, we notified Planet of the immediate termination of the license agreement and immediately prohibited the use of our intellectual property rights relating to “Cooking Mama”.

Despite this, Planet continues to sell the Nintendo Switch version of “Cooking Mama: Cookstar” without our permission, and even sells the Sony PlayStation 4 version of “Cooking Mama: Cookstar” to all over the world, excluding Asia. It’s time to get started.

Therefore, we have personally sued Planet and its CEO Steve Grossman before the International Court of Arbitration of the International Chamber of Commerce (ICC) for the unauthorized manufacturing and production of the Switch and PlayStation 4 versions of Cooking Mama: Cookstar. We had filed for arbitration seeking a ban on sales, etc., and on October 3, 2022, the ICC Arbitration Tribunal issued a final ruling.

In this final ruling, the ICC Arbitration Tribunal ruled that Planet and Mr. Grossman did not have the authority to manufacture and sell “Cooking Mama: Cookstar” for both the Switch and PlayStation 4 versions, and that the “Cooking Mama : Cookstar” unauthorized was found to infringe our intellectual property rights. In addition, the ICC Arbitration Tribunal has prohibited Planet and Mr. Grossman from any action that misleads the company on the basis of infringement of intellectual property rights , unfair competition, etc.

In order to protect the important assets of the “Cooking Mama” series and obtain the patronage of our customers, we have taken all legal measures to remove “Cooking Mama: Cookstar” manufactured and sold by Planet from the market. I am here. We sincerely apologize for the great confusion and inconvenience caused to our longtime Cooking Mama customers due to the illegal acts of Planet and Mr. Grossman.
