Inequitable Conduct

The district court and CAFC found Dr. Bernard Charles Sherman, founder and chairman of Apotex, guilty of inequitable conduct in his patenting of an antihypertensive claimed in 6,767,556. "Dr. Sherman breached his duty of candor, good faith, and honesty before the PTO." Typical CEO behavior, especially in the big leagues. But then, Dr. Sherman was just another crooked player in a very crooked game. Abusing the law is bread-and-butter business for Federal judges, particularly when patents are asserted by small fry against corporate giants.

Double Standard

37 CFR 1.56 requires a "duty to disclose information material to patentability," but the CAFC won't uphold it. "[T]his court has now made clear that "[t]o prevail on a claim of inequitable conduct, the accused infringer must prove that the patentee acted with the specific intent to deceive the PTO." Therasense, 649 F.3d at 1290. Moreover, '[a] finding that the misrepresentation or omission amounts to gross negligence or negligence under a 'should have known' standard does not satisfy this intent requirement.'" 1st Media v. Electronic Arts (CAFC 2010-1435). Accountability is certainly not what the CAFC is about.

French Fried

5,750,561 owner Aventis sued Hospira and Apotex for infringing the cancer drug concoction. Co-inventor Jean-Louis Fabre withheld references from the PTO during prosecution, and it caught up with him, and Aventis. "There simply is no justification for telling the [PTO] about the prior art disclosing the problem [Fabre] examined while concealing key prior art disclosing the solution he chose." Overcoming the high hurdle of inequitable conduct set in Therasense, '561 had terminal cancer before it was shot in the heart. The claims were also found obvious. Affirmed on appeal (CAFC 2011-1018).

American Calcar (ACI) sued Honda for infringing 15 car computer patents. The number of patents asserted hardly made up for spotty quality. Only one was found valid and infringed at district court. Nine were appealed over validity, infringement, and inequitable conduct. The whiff of impropriety by ACI, while not legal damnation, was enough to bias the courts, and, in the end, let Honda drive on, patent toll free.

Therasense, now Abbott, got into a patent battle involving 5,820,551 and similar patents claiming "disposable blood glucose test strips for diabetes management." The ubiquitous allegation of inequitable conduct found purchase, for failing to disclose in U.S. prosecution highly relevant prosecution posturing in Europe. Upheld on appeal. Now, in a 6-5 en banc bungle that wipes away much history and seasoned sense that demands accountability for prosecution weaseling, a new rigid rule rules the roost, sending the '551 chicken back to the broiler of district court. The irony is that the new rigid rule, in the name of tightening, actually loosens the bonds obliging honesty. A CAFC majority seems unable to consider the dynamics of consequence.

Lazare Kaplan International owns patents claiming laser microinscribing of gemstones. Two of them, 6,476,351 and descendant 7,010,938, were asserted against PhotoScribe and others. Claim construction resulted in a summary judgment of literal noninfringement. But Lazare was allowed to argue the doctrine of equivalents to the jury. The jury found the patents not infringed, and not valid. In a bench trial that followed, the district court found inequitable conduct, for failing to disclose "the Gresser machine" to the USPTO. Under contract, Herbert Gresser created a nifty machine to air-cushion the inscriber for Lazare. '351 mentioned Gresser's work (and patent, 4,392,476, which Lazare also owns), but only in passing.

Mapping the Territory

A patent is supposed to be an instruction manual. 35 U.S.C. §112 ¶1 requires an inventor to describe her invention "in such full, clear, concise, and exact terms" that it would "enable any person skilled in the art to which it pertains." Windbags who fail the concise requirement are seldom punished. Clarity is as often observed in the breach as not, with infrequent repercussion. Teasing out meaning is tolerated - pointing out obtuse passages for support is not regarded untoward. But fail "full" or "exact," and you're in a peck of trouble. Herein, a broad claim of an early advance falls short. And in an invigorating dissenting concurrence, the sin of not enabling enablement.

Inequitable Conduct

Professor Lisa A. Dolak of Syracuse law school has given considerable research and thought to what amounts to a death sentence for patents. Excerpts from a paper presented last month -

There is no question that inequitable conduct allegations drain resources and inject uncertainty into litigation. And, no doubt, the defense is overpled. But it is also undeniable that serious breaches of the duty of candor occur.

Furthermore, the reported instances of inequitable conduct represent only a small fraction of the cases which involve credible evidence of inequitable conduct. Most such cases presumably settle before trial. Accordingly, the inequitable conduct doctrine, like other defenses to patent infringement, curtails litigation in some cases, and presumably tends to function most efficiently where the evidence is the most compelling and the allegations the most meritorious. Eliminating the defense would lead to an increase in the instances of successful enforcement of patents procured through deception, and, likely, an increase in attempts to mislead the USPTO.

In a touchstone ruling, Star Scientific v. R.J. Reynolds, the CAFC resets the high bar for inequitable conduct:

The burden of proving inequitable conduct lies with the accused infringer. The patentee need not offer any good faith explanation unless the accused infringer first carried his burden to prove a threshold level of intent to deceive by clear and convincing evidence. If a threshold level of intent to deceive or materiality is not established by clear and convincing evidence, the district court does not have any discretion to exercise and cannot hold the patent unenforceable regardless of the relative equities or how it might balance them. Even if a threshold level of both materiality and intent to deceive are proven by clear and convincing evidence, the court may still decline to render the patent unenforceable.

The Plague

McKesson Information Solutions sued Bridge Medical for infringing 4,857,716. The patent was trashed by inequitable conduct; a district court ruling upheld at the appeals level (CAFC 06-1517) in a split decision. Has the appeals court, in the dissent of Judge Newman, returned "to the "plague" of encouraging unwarranted charges of inequitable conduct, spawning the opportunistic litigation that here succeeded despite consistently contrary precedent"?

Open Outcry

Cantor sued Brokertec over 6,560,580, which claimed trading fixed income securities, replacing the prior art of "open outcry" trading. When Cantor asserted '580, it dredged a past it could not erase: Cantor had initially failed to disclose earlier work, then put forth a disingenuously deceptive declaration to cover that up. About intent to deceive: "The affirmative act of submitting an affidavit must be construed as being intended to be relied upon."

Patent Speed

In a press release celebrating its prosecution con job, the USPTO wants your patent application on virtual methamphetamine. Just like the self-destructive nature of chemical speed on the human body, accelerated examination may feel like a rush towards patent grant, while leaving the patent holder with open-ended liability.

Deep Freeze

Dippin' Dots owns 5,126,156, which claims a process for making ice cream. "The Dippin’ Dots brand is known to patrons of amusement parks, stadiums, shopping malls, and the like." After Dippin's distributors turned competitors, Dippin' flipped into patent enforcement, suing left and right. Counterclaim included antitrust, on what defendants called a fraudulently acquired patent. Claim construction, infringement, prior art (including a newly minted definition of "obvious"), inequitable conduct; it's all in the dip. (CAFC 05-1330)

NetFlix Rebuffed

Netflix sued Blockbuster for patent infringement in April, and Blockbuster retorted in countersuit that Netflix was just attempting monopolization via unenforceable patents; unenforceable owing to inequitable conduct: that Netflix didn't disclose known prior art. Netflix tried, unsuccessfully, to get the judge to dismiss the countersuit.

To say that Norwegian Ole K. Nilssen went about it the wrong way would be understatement. Though not found guilty of unclean hands, the man is a disgrace. Pray tell, I am referring to five kinds of inequitable conduct. Is there a Guinness record for this sort of thing?!

Bad Deceiver

In Bayer AG v. Housey Pharmaceuticals, today the U.S. Court of Appeals (CAFC 06-1083) affirmed that Dr. Gerard M. Housey is a lying weasel, his four patents 4,980,281; 5,266,464; 5,688,655; and 5,877,007 voided for inequitable conduct. This guy made a seriously lousy impression on the court.

Up the Creek

Old Town Canoe sued Confluence Holdings for infringing 4,836,963, which goes to a process for making plastic boat hulls by rotational molding. Confluence got a summary judgment of non-infringement based upon claim construction, but lost counterclaim motions on invalidity and enforceability. So the parties appealed the rulings that went against them. The CAFC (05-1123) found the district court had been hasty in some of its summary judgment rulings, glossing over disputable facts. And a well-reasoned dissent argued that the whole case was overdone.

Inequitable Conduct - Intent

S&G Tool Aid sued Astro Pneumatic Tool for threatening its customers with patent infringement (5,259,914), over a portable car sticker remover. S&G went whole hog, seeking declaratory judgment of non-infringement, inequitable conduct, unfair competition, tortious interference, false marking, and violations of the Lanham Act & New Jersey Fair Trade Act to boot. S&G got an inequitable conduct summary judgment ruling out of district court, "determining that there was clear and convincing evidence of materiality and intent to deceive" the patent office. The appeals court said (CAFC 05-1224), not so fast.
