Patent Strikeout

by Geoff Mantooth

2003 | Originally published in Fort Worth Business Press

Last month, the Supreme Court upheld California’s “three strikes and you’re out” law for convicted felons. That case was particularly difficult because the guy got caught stealing about $400 worth of golf clubs, yet this third conviction landed him a harsh 25 year prison sentence.

In contrast to criminal law, the government doesn’t always keep count of the number of strikes against an inventor. Because their behavior is inherently less harmful than crime, inventors have lots of chances to lock up protection on an invention.

About a decade ago, two Wisconsin smelt fisherman came up with an idea. Fast growing to 7-8 inches, smelt swim around the Great Lakes region. One way to catch smelt is by ice fishing. In the winter, some folks prefer going to the mall while others trudge off to fish on the ice.

Sun or snow, fishing is one of those inspirational hobbies. When the fish are biting, ahhhhh, life is soooo good. If they aren’t, fishermen have lots of time on their hands and tend to dream up new ideas. There are lots and lots and lots of fishing inventions.

These two fishermen became concerned with zebra mussels. Like smelt, zebra mussels are nonnative to the Great Lakes. Unlike smelt, they don’t provide hours of pleasure. Instead, the mussels are like huge barnacles, growing everywhere, fouling everything. They proliferate at the fabled speed of rabbits, crowding out other species by taking up all of the good underwater real estate and devouring the food.

Their invention uses an acoustic generator tuned to a particular frequency. The thing vibrates loudly underwater and fatally breaks the shell of any nearby zebra mussel. The principle is akin to an opera singer singing so loud and pure that the wine glass shatters.

Something else that probably works is dynamite, where you get one loud BOOM! A few ice fishermen have been known to use Alfred Nobel’s invention to both break the ice and float a few fish.

For the two inventors, strikes one and two came from the Patent Examiner and the Appeal Board that backed the Examiner’s decision of unpatentability. The Examiner’s decision was based on earlier patents and research. One patent told how to kill zebra mussels using acoustics… sounds close right? Well yes, but the inventors argued, unsuccessfully, that their invention used an oscillator, while the earlier inventions used a plasma sparker to make the acoustic noise.

Their next at bat was somewhat unusual. Instead of appealing to a circuit court, the inventors essentially asked for a new trial in federal district court. By doing so, new evidence can be introduced. There’s also the fact that the Patent Office loves to complain about how much it costs to examine patents and how little money it actually has. So it’s a bet that in a trial the Patent Office might not put up a stiff fight.

Except… the tactic backfired. The Patent Office found some new evidence of its own, a German research paper that detailed the same invention. The government attorney also dynamited the inventors’ new evidence through some questioning of the witness. Thus, the trial court threw the third strike. Not only that, the trial court tried to have one of the inventors, a lawyer representing himself, ejected from the game for filing a smelty motion.

The fourth strike came at the appellate court level. The inventors said that the German paper was in a foreign language than neither one understood. As in criminal cases, where ignorance of the law in no defense, in patent cases, ignorance of a foreign language does not make an old invention patentable.

Striking out in patents doesn’t mean that the invention is dead. The inventors just can’t keep others from copying it.

One wonders about the commercial potential of the noise maker invention. If the US Navy catches flak due to its sonar disturbing the whales in the big oceans, there’s bound to be some non-zebra animal that hates the noise. So, not even counting the Patent Office, the strikeout may come from environmental regulations.

A few months ago, this column reported on the Victoria’s Secret case, where a Kentucky novelty shop had adopted the name “Victor’s Secret”. Victoria’s Secret sued and won, although not on the question of trademark infringement. Instead, the lower courts held that Victor’s Secret diluted the value of the Victoria’s Secret mark.

The Supreme Court slapped the briefs of Victoria’s Secret, ruling that its evidence of dilution was too threadbare. The ruling is significant because it establishes that to show infringement of a trademark, the owner need only show a probability of such, while to show dilution, actual dilution is required. Imagine trying to prove that a coin will come up heads when tossed. The probability of heads is easier to prove than the actuality. Unless the two sides settle their differences, the case returns to a lower court.
