To the Director of Mugen Denko Co.,
Subject: Usage of airbag jackets
The patent application documentation can be requested at any time from the Hungarian Intellectual Property Office, and the following website contains further information on the subject at issue: www.motor-airbag.com I would like to note that my client did not conclude the entire patent procedure at the time, but irrespective of this fact, the airbag jacket and the substantive elements thereof, i.e. the solution was made public in 1977 or, at the latest, beyond any reasonable doubt, in 1983 upon the patent application . You can verify the above facts by comparing the description of the patent report made by my client in 1976 with the product manufactured by your company. Even an objective examination reveals much similarity, and based on the description, the expert can manufacture the current product based on his best knowledge. Taking the foregoing into account, your were in all probability mistaken when you paid/pay license fees to Kenji Takeuchi as holder of the patent for a global novelty.
I would hereby like to ask you to state your position in this issue within 30 days of receipt of this letter. Please state whether you acknowledge my client’s priority, and if you are still making payments for the use of the patent, whether you are willing to pay liquidated damages to my client under the legal title of know-how fee.
