日本における特許侵害訴訟の提起について

2011年5月25日

株式会社ニコン（社長：木村眞琴　東京都千代田区）は、2011年5月25日、株式会社シグマ（神奈川県川崎市、以下シグマ社）に対する特許侵害訴訟を東京地方裁判所に提起いたしました。この訴訟において、一眼レフカメラ用交換レンズの日本における該当特許侵害行為の停止と損害賠償を求めています。

当社は、映像事業を始めとするさまざまな分野において長年に渡って研究開発に投資してまいりました。その成果の一つとして得られた知的財産権は当社の重要な経営資産であり、また、当社はそれらを活用することによって、お客様のご要望にお応えする製品・サービスを継続的に提供することができております。

かねてシグマ社による当社特許の侵害行為があり、当社といたしましては交渉による解決を図るべくシグマ社と協議を行ってまいりましたが、残念ながら解決するに至らず、やむを得ず訴訟を提起することといたしました。

なお、該当特許は、手振れ補正機能を搭載した交換レンズに関するものです。

Sollte das stimmen und Sigma das "OS"-System zurückziehen müssen, hätte das natürlich auch Auswirkungen auf Sigmas A-Bajonett-Objektive mit Bildstabilisator - nicht wirklich schlimm für DSLRs, die ja bekanntlich ihr eigenes Stabilisierungssystem mitbringen, aber da Sigmas "OS"-System auch an manchen Filmgehäusen mit A-Bajonett funktioniert, wäre das ein Verlust für die Analogfraktion.

Hast Du die Pressemitteilung lesen können?

Mist, ich habe vorhin nur überprüft, ob es eine deutsche Presseerklärung zu dem Sachverhalt gibt, aber Fehlanzeige, das dauert wahrscheinlich noch ein paar Tage. Deshalb der japanische Originaltext (ich hab die Sachen gerne im Archiv, damit man später, in ein paar Jahren oder Jahrzehnten, wenn die Links weggebrochen sind, weiß, worum es ging).

Auf die Idee, daß es vielleicht eine englische Fassung geben könnte, bin ich aber irgendwie nicht gekommen. Hier ist sie:
ZITATPress Release:

Nikon Corporation filed a patent infringement lawsuit in Japan

May 25, 2011 - Nikon Corporation (KIMURA Makoto, President, Tokyo, hereafter referred to as "Nikon" filed a patent infringement suit against Sigma Corporation (hereafter referred to as "Sigma" to Tokyo District Court on May 25, 2011. Nikon's lawsuit seeks an injunction against Sigma's manufacture and sale of infringing interchangeable lenses with vibration reduction for single lens reflex cameras, along with damages for past infringement.

Nikon has invested considerable resources in the form of research and development over a period of many years. Such investments have created intellectual property that are important business assets of Nikon and have enabled Nikon to continuously provide the products and services that satisfy its customers requirements.

Although Nikon attempted to resolve Sigma's patent infringement through negotiation, a non-adversarial resolution could not be reached. Consequently, Nikon concluded that filing a lawsuit was the only way it could protect its intellectual property.[/quote]
Die japanische Seite Digital Camera Watch nennt übrigens auch die ihren Informationen nach fraglichen japanischen Patente 3755609 und 3269223:

Ob es sich dabei wirklich um die fraglichen Patente handelt, um die es in diesem Rechtsstreit geht, kann ich nicht sagen, zumindest aber behandeln sie ein Bildstabilisierungssystem:

(54) ZOOM LENS CAPABLE OF IMAGE SHIFT

(57) Abstract:

PURPOSE: To make a lens diameter small, to easily control image shift, and to provide excellent image forming performance in the case of the image shift by moving a lens group arranged between a lens group and a 1st lens group closest to an object side along an optical axis and performing focusing on a short-distance object.

CONSTITUTION: This zoom lens is constituted of a 1st lens group G1, a 2nd lens group G2, a 3rd lens group G3, a 4th lens group G4 and a 5th lens group G5 in order from the object side. An aperture diaphragm S is arranged between the 3rd lens group G3 and the 4th lens group G4 and integrally moved with the 4th lens group G4 in the case of varying power from a wide-angle end to a telephoto end. In the case of varying the power to the telephoto end, it is moved on the optical axis along a zoom track. A bonding positive lens L42 in the 4th lens group G4 is moved in a direction nearly orthogonal to the optical axis so as to perform the image shift and correct the fluctuation of an image position. Furthermore, the 3rd lens group G3 is moved along the optical axis to an image side to perform focusing on a short-distance object.

(54) APPARATUS WITH ULTRASONIC MOTOR AND VIBRATION DETECTOR

(57) Abstract:

PURPOSE: To eliminate the resonance of a vibration detector by setting the resonance frequency band of the detector and the resonance frequency band of the motor in separate bands.
CONSTITUTION: An ultrasonic motor 5 is provided at a photographing lens 3, and a vibration detector 8 is provided at the lens 3 (or a camera body 1). A setter 9 sets the resonance frequency band of the motor (a drive source for matching a focus of the lens 3) 5 and/or a drive control range and a primary or secondary resonance frequency band and/or first or second resonance half- value band of the detector (blurring detecting sensor) 8 in separate bands. Thus, the detector is not resonated by the vibration of the motor 5, and an accurate vibration can be detected.

Nachdem es Anfang 2013 so aussah, als ob sich Sigma und Nikon außergerichtlich geeinigt hätten, hat nun ein Tokioter Gericht entschieden, daß Sigma 1,5 Milliarden Yen (umgerechnet etwa 14,5 Millionen US-Dollar) an Nikon wegen Patent-Verletzungen zahlen muß.
ZITAT"Nikon obtained the patent related to VR technology in 2002. The content of the patented invention relates to technology wherein a vibration detection device, which detects the amount of camera vibration at angles around photographic objects, prevents the influence of vibration of a motor for lens and thereby allows more accurate photo shots. Sigma affirms that the scope of the patented invention does not include any functions which reduce the influence of camera shake. However, Mr. Osuga, the Judge in Chief, states that the effects of the invention in Nikon’s specification is described as "it allows image blur to be reduced” and that the specification clears that it includes camera shake. Thus, Mr. Osuga stands for Nikon’s assertion. In addition, Mr. Osuga points out that image blur prevention system requires various control functions, and he states that this patented invention of Nikon’s should be rewarded based on the contribution of the patent to the defendant’s products, that is 15%. Therefore, the Tokyo District Court calculated profits earned by Sigma to be a maximum of 10.1 billion JPY, and found compensation of damages to be 15% of the profits of the Akkused products earned by Sigma."[/quote]
