Opinion

MEMORANDUM AND ORDER

VAN BEBBER, Chief Judge.

Plaintiff brings this patent infringement action alleging that defendant manufactures and sells ramps that infringe plaintiffs design patent for an arched lawnmower ramp. The case is before the court on plaintiffs motion (Doc. 2) for a preliminary injunction. The parties presented evidence at a hearing on plaintiffs motion on November 24, 1997. For the reasons set forth below, the motion is denied.

7. FINDINGS OF FACT

Pursuant to Fed.R.Civ.P. 52(a), the court makes the following findings of fact and conclusions of law.

1. Plaintiff Five Star Manufacturing, Inc. has been manufacturing aluminum loading ramps since 1986.

2. Plaintiff owns a design patent, U.S. Design Patent No. 331,305, for an arched lawnmower ramp. The design drawings depict an arch that reduces the angle of incline *1230 of the ramp as it approaches the upper end of the ramp. See Figures 1-6. Two longitudinal beams span the length of each ramp and define the arch of the ramp. Each beam consists of two rectangular bars welded together lengthwise. A center longitudinal beam consisting of only one rectangular bar also runs the length of the ramp. Cylindrical cross bars are welded on top of the ramp across the three longitudinal beams intermittently throughout the length of the ramp and fully extending across the width of the ramp. The upper end of the ramp contains three flat extensions the width of the longitudinal beams connected to the top of each beam and extending out several inches from the end of the beams.

3. Lonnie D. Adams, a co-inventor of the patented design, expended substantial time and resources in developing the patented design. Adams Distributing Company, which sells plaintiffs ramps manufactured under the design patent, spent over $50,000 on advertising for the ramps. Neither Lonnie D. Adams nor Adams Distributing is a plaintiff in this case. Nor is Adams an employee of plaintiff.

4. Plaintiff attempted to obtain a utility patent on the arched ramp but abandoned such pursuit after it realized prior art would preclude it from receiving a utility patent.

5. Defendant Ramp Lite Manufacturing, Inc. has been manufacturing and selling aluminum ramps since 1996. Defendant sells its ramps by phone and through dealers that it solicits to sell the ramps. At least three dealers in Kansas sell defendant’s ramps and advertise the ramps by brochure.

6. Defendant manufactures a ramp containing many of the features included in plaintiffs design patent drawings. See Figure 7. The arch of the ramp is almost identical to the arch in the drawings. The ramp has two rectangular outside longitudinal beams. Cylindrical cross bars are similarly spaced throughout the length of the ramp. The ramp also has fiat metal extensions connected to the upper end of each longitudinal beam.

7. Plaintiff asserts that the design patent protects the following features of the ramp design: the arch, the longitudinal beams, the cross bars, and the extensions at the top end.

8. The patented design and the accused ramp differ in the following respects: the cross bars in the patented design are across the top of the ramp, while the cross bars of the accused ramp are underneath the top of the longitudinal beams; the longitudinal beams in the patented design are two smaller beams welded one on top of the other, while the longitudinal beams of the accused ramp are each one single piece of metal; the patented design has only one center longitudinal beam, while the accused ramp has two center longitudinal beams.

9. The purpose of the arch in the ramp design is to reduce the angle of the incline as a lawnmower approaches the surface on which it is loaded. The specific arch is necessary to provide clearance in the loading of Snapper brand lawnmowers. The arch also provides strength for the ramp. The longitudinal bars are vertically longer than they are wide to supply support for the weight on the ramp. The longitudinal bars are rectangular to provide a welding area on which to connect the cylindrical cross bars. The cross bars are cylindrical to provide the most strength with the least weight, and to allow the loaded vehicle to get traction in all weather conditions. The cross bars are spaced to prevent the wheels of the loaded vehicle from slipping between them. The extensions from the upper end of the ramp are provided to allow the ramp to hang on the edge of the loading surface and to provide a flat level surface between the ramp and the loading area.

10. Plaintiffs witnesses testified that the following alternative ramp designs are available: a long, straight ramp or a ramp with a bend instead of an arch. Neither, however, are feasible options. A straight ramp long enough to provide clearance for lawnmowers would violate freight regulations. The ramp with a bend would not assist in the loading of Snapper lawnmowers because it would provide insufficient clearance for the lawnmower to roll up the ramp without striking either the ground or the ramp. Plaintiffs witnesses also suggested alternatives to the patented design including a forklift or several persons lifting the lawnmower.

*1231 11. The court finds that the patented design is functional. Although plaintiff argues that the choice of design was made for aesthetic, non-functional purposes, the evidence clearly discloses that the arch, the longitudinal beams, the cross bars, and the flat extensions are all functional aspects — going far beyond ornamental. Moreover, plaintiff has failed to show that any alternative ramp designs could fulfill the same functions that the patented design fulfills.

12. Plaintiff believes another manufacturer is also infringing the design patent. Plaintiff, however, has declined to sue the other manufacturer for patent infringement. In exchange, the allegedly infringing manufacturer agreed not to sue plaintiff for infringement of another patent.

II. CONCLUSIONS OF LAW

The district court has subject matter jurisdiction over this dispute pursuant to 28 U.S.C. § 1338. Venue is proper in this district pursuant to 28 U.S.C. § 1400(b) because defendant allegedly infringed plaintiffs design patent in this district and defendant has a regular and established place of business in this district.

The court has discretion to grant or deny a motion for a preliminary injunction. Polymer Technologies, Inc. v. Bridwell, 103 F.3d 970, 973 (Fed.Cir.1996). Four factors are relevant to a preliminary injunction analysis:

(1) a reasonable likelihood of success on the merits;
(2) irreparable harm if the injunction were denied;
