As experienced trial lawyers know, successfully trying or defending a case is all about presenting a compelling, understandable theme and narrative that comports with a judge and jury’s common sense and experience.
Juries especially are prone to favor litigants and lawyers they like and case theories they easily understand. That is human nature on display in the courtroom.
Certain types of patent claim theories and defenses possess greater “narrative allure” than others. In patent litigation, the inventor’s journey of discovery is often a key trial narrative, including a recitation of the trials and tribulations incurred on his or her way to obtaining an official U.S. patent—together with its certified seal and blue ribbon.
For those accused of infringing patents—whether through being named as a defendant or identified as a culprit in a cease-and-desist letter writing campaign—the best choice for a compelling defense story is often less apparent. Affirmative defenses, compulsory counterclaims or declaratory judgment causes of action are often asserted in blunderbuss fashion in order to preserve any and all claim or defense theories.
Patents and their dense, impenetrable prose and complicated technical and scientific jargon often make little sense to the uninitiated—i.e., to almost everyone other than inventors, patent prosecutors, expert witnesses, and patent litigators. Advances in cognitive science are now showing that jurors will seek to avoid the mental strain associated with deciphering difficult trial testimony and jargon, and will instead rely on simpler, preconceived notions of how businesses and their executives operate in rendering their jury verdict decisions.[1]
By virtue of its relative simplicity and the seeming ease by which it can be understood by a lay jury, a “Walker Process” antitrust claim offers an appealing defensive/offensive claim theory for alleged patent infringers. Named after a leading Supreme Court case[2] decided in 1965, a Walker Process claim stands for the proposition that “the enforcement of a patent procured by fraud on the Patent Office may be violative of § 2 of the Sherman Act provided that the other elements necessary to a § 2 [monopolization] claim are present.”[3]
The financial incentives for pursuing a Walker process claim are quite significant: a prevailing litigant may be able to recover treble damages and attorneys’ fees. These claims most often appear as a compulsory counterclaim to an allegation of patent infringement. However, they can also be asserted affirmatively, along with declaratory judgment claims for patent non-infringement, invalidity and unenforceability.
The jury appeal and potential monetary rewards of a Walker Process claim also raise corollary patent legal malpractice risks for both parties. For the party prevailing on such a claim, the risks for the other side are obvious: a patent has been held unenforceable due to inequitable conduct and the client is facing a potentially huge monetary exposure or judgment for damages and the successful party’s attorneys’ fees and costs. Even if the Walker Process claim is ultimately unsuccessful, the losing party may argue that the patent counsel’s prosecution conduct increased the litigation costs of enforcing a patent right and resulted in a weakened settlement position.
For the party who pursues and loses a Walker Process claim, the failure of the claim may well be due to an inability to meet one or more of the procedural and substantive requirements that accompany Walker Process claim litigation. For example, if the client is not properly advised about these detailed requirements, or if proof was not appropriately marshalled and applied to various Walker Process claim elements, the failed claim may also subject the patent litigator to unwelcome malpractice exposure.

The Federal Circuit’s recent precedential decision,
The recently concluded (and now appealed) Gardner v. Toyota Motor Corporation patent case offers yet another important lesson in the pitfalls of missing case schedule deadlines. These deadlines inundate patent litigation, especially with the advent of many local patent rules.
“Then, I said, let us begin and create in idea a State; and yet the true creator is necessity, who is the mother of our invention.”
It is commonplace to bemoan the lack of juror comprehension in patent cases and to describe jury deliberations as a “black box” resisting analysis.
