Cooking Mama IP Owner Sues Planet Entertainment Over Sale of Cooking Mama: Cookstar

Cooking Mom: Cooking Star

Remember the ongoing dispute between Cooking Mom: Cooking Star Does the publisher Planet Entertainment and rights holder for the Office Create series date back to 2020? Well, in an update, Office Create has sued Planet.

In fact, there was a dispute between the two parties prior to the game’s release in 2020, but Planet Entertainment went ahead and released the game worldwide in digital and physical form. The copyright holder Office Create at the time released an official statement, calling it an “unauthorized release”.

It seems that the International Chamber of Commerce sided with Office Create in the end, acknowledging how the release of Cooking Mama: Cookstar violates intellectual property rights. Office Create is now looking to take all remaining physical copies off the market. Digital copies have apparently already been withdrawn from sale.

Here’s a rough translation of the latest Office Create update, via its official website:

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

As we reported to you in April 2020, Planet Entertainment LLC (based in Connecticut, USA; hereinafter referred to as “Planet”) violated our license agreement and released the Nintendo Switch version of Cooking Mama: Cookstar, which does not met quality standards, without our permission, and began sales activities in North America, Europe, and Australia. In addition, in the United States and Europe, we began to advertise for sale the Sony PlayStation 4 version of “Cooking Mama: Cookstar”, which we did not grant 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 related 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” worldwide, except in Asia. It’s time to start.

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

In this final ruling, the ICC Court of Arbitration found that Planet and Mr. Grossman did not have the authority to manufacture and sell “Cooking Mama: Cookstar” for the Switch and PlayStation 4 versions, and that the unauthorized version of “Cooking Mama: Cookstar has also been prohibited by the ICC arbitration court for Planet and Mr. Grossman from taking any action that misleads the company on the grounds of intellectual property rights infringement, unfair competition, etc.

In order to protect the important assets of the “Cooking Mama” series and win the patronage of our customers, we have taken all legal steps to recall “Cooking Mama: Cookstar” manufactured and sold by Planet. We sincerely apologize for the great confusion and inconvenience caused to our former Cooking Mama patrons due to the illegal acts of Planet and Mr. Grossman.
