I sincerely hope that no one thinks I am flaming anyone or trying to start any trouble. I have thought long and hard about posting anything else on this thread for the fear that it may appear as such.
For those that don't know we are based on precedent here. We go by what the highest court that has heard the case says. Laws can also change as they did in 1999 with the Lanham Act and the Trademark Law Treaty Implementation Act, also 1999. I believe Spyderco's trademark was granted before the changes and clarifications were made, but I could be wrong.
I am NOT stating my opinion here, but would like to qoute some recent court cases on the issue. I have included the case names and courts so please feel free to look them up. Again, I am posting these for discussion purposes only. Lets try and keep this civilzed.
In Eppendorf-Netheler-Hinz (5th Circuit, 2002), product trade dress in disposable pipette tips were held to be functional. Ritters tips were substantially identical in design and were even marketed as a direct replacement. Eppendorf relied on evidence that many different designs could be used to produce a pipette that functioned well and did not look like Eppendorfs. The Fifth Circuit court held this irrelevant; the evidence conclusively established that the elements claimed to constitute the trade dress served a functional purpose.
Another court case Value Engg Inc vs. Rexnord Corp(Fed. Cir. 2002) says that a court may still consider the existence of alternative designs in deciding whether a design is functional; but having found that it is cannot give trademark protection to a functional design merely because there are alternative designs available.
Clicks Billiards, Inc. vs. Sixshooters Inc. (9th Circuit, 2002) the court states trade dress cannot, however, be both functional and purely aesthetic.
TrafFix Devices Inc. vs. Marketing Displays Inc (U.S. Supreme Court, 2001) considered functionality in the context of a trade dress comprising a formerly patented, dual spring mechanism for temporary road signs. The 6th Circuit had previously held that the availability of spring mechanisms that would function equivalently, but looked different, raised a fact issue to non-functionality. The U.S. Supreme Court overturned that finding that the dual spring design was functional as a matter of law, holding that the availability of functionally equivalent, alternative designs of differing appearance was immaterial and did not raise an issue of fact.
