JOHNSON WORLDWIDE ASSOCIATES, INC. v. Zebco Corp., 50 F. Supp. 2d 863, 1998 U.S. Dist. LEXIS 22379, 1998 WL 1056984 (W.D. Wis. 1998).

Opinion

*864 MEMORANDUM AND ORDER

SHABAZ, Chief Judge.

Plaintiff Johnson Worldwide Associates, Inc. commenced this patent and copyright infringement action alleging that the defendant Zebco Corporation (“defendant”) is manufacturing and selling a bow mounted electric trolling unit which infringes plaintiffs' U.S. patent no. 5,202,835 (the ’835 patent) and that defendant unlawfully copied plaintiffs sales brochure for the trolling unit. Jurisdiction is based on 28 U.S.C. § 1338. The matter is presently before the court on cross motions for summary judgement on the patent claim and on plaintiffs motion for summary judgment on the copyright claim.

FACTS

The following is a summary of the relevant undisputed facts. Plaintiff and defendant aré competitors in the manufacture and sale of trolling units 1 . Plaintiff developed and obtained the ’835 patent on a self steering trolling unit which generally maintains a fixed direction thereby reducing the need of the user to steer while fishing. The ’835 patent was issued as a continuation of United States Patent No. 5,172,324 (the’324-patent).

Claim 1 of the ’835 patent, the only independent claim alleged to be infringed provides as follows:

1. A heading lock coupled to a trolling motor producing a thrust disposed to pull a watercraft, said heading lock comprising:
a steering motor coupled to said trolling motor, said steering motor being disposed to affect the orientation of said trolling motor in response to input signals;
a steering circuit electrically coupled to said steering motor, said steering circuit begin (sic) disposed to generate said input signals to said steering motor in response to heading signals; and
a heading detector electrically coupled to said steering circuit, said heading detector being disposed to transmit said heading signals to said steering circuit.

Claims 2 and 5, which depend from claim 1, provide:

2. The heading lock of claim 1 wherein said heading detector includes a compass, said compass including a pair *865 of light emitting diodes, said compass farther including a pair of photo-transistors mounted so as to be optically coupled to said pair of light emitting diodes.
$ $ ‡ ‡
5. The heading lock of claim 4 wherein said trolling motor has a variable orientation, said orientation being selectable, the direction of said thrust being responsive to said orientation, wherein said heading detector generates a feedback signal indicative of the orientation of said trolling motor, and wherein said steering motor effects a change in said orientation in response to said feedback signal.

The preferred embodiment of the invention employs a compass physically mounted to the head of the unit which monitors the direction of the thrust motor. The description of the preferred embodiment identifies as one significant aspect of the invention the fact that the heading of a bow mounted thrust motor will be the same as the heading of the boat. The following are particularly relevant portions of the description of the preferred embodiment:

A boat having a thrust motor that pulls the boat (a motor that precedes the center of gravity of the boat in the direction of travel) will, if the heading of the thrust motor is held constant, eventually follow the thrust motor and travel in the heading of the thrust motor. Examples of thrust motors that pull a boat include: a bow mounted trolling motor (thrust motor) used with a fishing boat; (Column 3, Lines 17-24)
‡ ‡ sjc :¡< %
Since the boat 104 always follows a course established by trolling unit 102 a single compass may be used to determine the current heading of both trolling unit 102 and boat 104. (Column 4, Lines 48-51)

Defendant’s AutoGuide unit does not determine the heading by a compass mounted to the head of the trolling unit. Rather, the heading is detected by a two-axis magnetometer located in the foot pedal containing the user controls. The foot pedal of the AutoGuide unit contains a microprocessor which receives signals from the magnetometer and conveys steering signals to the steering motor. The head of the AutoGuide unit does not change with a change in the direction of the thrust motor. Instead the steering motor located in the head of the AutoGuide unit rotates the thrust motor shaft independently of the motor head.

Plaintiff designed and distributed its 1997 Marine Catalog which included a two page advertisement for its MinnKota AutoPilot trolling unit. On September 5, 1997 the United States Copyright office issued a Certificate of Registration for the advertisement. In the summer of 1996 defendant obtained a copy of the catalog and provided it to its advertising agent, Brothers & Company, for the purpose of developing an advertisement for Auto-Guide. Defendant informed Brothers that the AutoPilot was JWA’s version of the AutoGuide. Brothers developed an advertisement for the AutoGuide trolling unit providing the individual writers and illustrators with copies of the AutoPilot ad for reference.

The AutoGuide advertisement contains numerous similarities to the AutoPilot advertisement in text, graphics and layout. Each ad contains six pictures depicting the use of trolling units under specific circumstances. The pictures in the ads are strikingly similar. Each picture in both ads has accompanying text explaining the features of the trolling unit. The following are the text associated with similar pictures depicting five boats surrounding a point in a water body:

Plaintiffs ad: “AutoPilot is perfect for trolling or casting along sand bars and points. When you get to the end, just point AutoPilot down the other side and start fishing. AutoPilot will lock onto the new heading and take you where you pointed — automatically!”
Defendant’s ad: AutoGuide is great for trolling along points and sand *866 bars. When you reach the end, simply turn AutoGuide down the other side and start fishing. AutoGuide locks onto the new heading and takes you where you want to go.

Other text comparisons reveal the same type of similarity.

MEMORANDUM

Defendant seeks summary judgment on plaintiffs patent infringement claims arguing that its AutoGuide unit falls outside the properly interpreted elements of claim 1 of the ’835 patent. Plaintiff contends that the defendant’s trolling unit contains each and every element of claim 1 properly construed and, even if outside the literal language of claim 1, the AutoGuide unit employs the equivalent of the elements of that claim.
