Nonprecedential Federal Circuit Decision Generates a Dissent

The Federal Circuit recently issued a non-precedential opinion in Vehicle IP, LLC v. AT&T Mobility, LLC. Perhaps the most interesting aspect of this decision was that it was a non-precedential opinion with a dissent, which to some extent seems a bit contradictory.

According to Federal Circuit Rule 32.1(b), “[a]n opinion or order which is designated as nonprecedential is one determined by the panel issuing it as not adding significantly to the body of law.” Still, a non-precedential decision with a dissent strikes me as odd. Perhaps this was a decision largely left to the staff attorneys. I suppose on some level it really doesn’t matter because Federal Circuit Rule 32.1(c) does not prohibit citation to nonprecedential dispositions issued after January 1, 2007.

I would have to think that this decision, which required the Federal Circuit to construe claim terms, would have to be precedential in at least some ways, unless the outcome in this case will not have any implication for the claims themselves or the patent. I guess I just don’t understand the concept of a nonprecedential claim construction. I cannot fathom a nonprecedential order in a real property boundary dispute. The whole point of suing over real property is to get a decision that is binding. Patents are property and it strikes me that the definition of the metes and bounds of what is covered in the claim really has to be precedential. If it isn’t precedential what is the point? This type of disposition is what leads to patent claims being construed to mean one thing in one case and another thing in another case. It is frustrating.

The Federal Circuit recently issued a decision in CardSoft v. Verifone, which the Court overturned the district court’s claim construction. Overturning a district court’s claim construction is hardly unusual, and perhaps more typical than it really should be, but that is another story for another day. What was unique about this particular case was that the Federal Circuit also went on to rule that CardSoft had waived any argument that the defendants had infringed under what they determined to ultimately be the correct claim construction.

CardSoft filed this patent infringement suit in March 2008 against VeriFone, Inc., VeriFone Systems Inc., and Hypercom Corp. (collectively, “Defendants”), asserting infringement of U.S. Patent Nos. 6,934,945 (“the ’945 patent”) and 7,302,683 (“the ’683 patent”). The district court held a Markman hearing in July 2011 and conducted a jury trial in June 2012. The jury determined that certain of the Defendants’ devices infringed claim 11 of the ’945 patent and claim 1 of the ’683 patent and that these claims were not invalid. The Defendants moved for a new trial and for judgment as a matter of law, but the district court denied both motions.

The United States Patent and Trademark Office (USPTO) announces the launch of a new Glossary Pilot as part of a White House Executive Action designed to enhance claim clarity in the specification of software-related patent applications.

The pilot runs for six months from the start date of June 2, 2014.

Will the Supreme Court Weigh in on Claim Construction Appeals?

The Federal Circuit has affirmed once again—this time in a sharply divided en banc decision—that it will subject a district court’s claim construction to de novo review on appeal. The case is Lighting Ballast Control v. Philips, and the appeal was the latest challenge to the standard of review set by the Federal Circuit over 15 years ago in Cybor Corp. v. FAS Technologies, Inc.

On the surface, this question of patent procedural law seems innocuous enough, but a glance at the title pages of the numerous amicus briefs (filed by an impressive roster of academic commentators and industry heavyweights) shows otherwise.  The question of the appropriate standard of review for claim construction rulings is of immense importance to the patent bar.

At stake in Lighting Ballast was the Federal Circuit’s ruling 15 years ago in Cybor, that claim construction is subject to de novo review at the appellate level, despite the fact that the interpretation of patent terms often has factual underpinnings, a domain where trial judges are usually given a wide berth and significant deference.  As the Supreme Court recognized in its landmark decision in Markman v. Westview Instruments, decided in 1996 shortly before Cybor, claim construction is a “mongrel practice” of both law and fact that often involves “construing a term of art following receipt of evidence.”

Cybor has been criticized both by Federal Circuit judges and by outside commentators, with most critics deriding Cybor’s blindness to the factual issues that are often implicit in the interpretation of what a patent means.  While the question can sometimes be answered by reference to the terms of the patent alone—a traditional legal inquiry—it oftentimes also requires extrinsic evidence and the opinions of dueling experts on the state of the art and the technology in question—factual issues traditionally left alone absent “clear error.”

Conjunctions and/or Patent Claims

As the late Judge Rich famously wrote in 1990, “the name of the game is the claim.”  Extent of Protection and Interpretation of Claims—American Perspectives, 21 Int’l Rev. Indus. Prop. & Copyright L. 497, 499.  That is, a beautifully-written Detailed Description section of a patent’s specification is pointless if the patent’s claims are drafted in a manner that renders their infringement remote or even near impossible!  Okay, so why is this important?  Well, let’s start with one of the Patent Bar’s best-kept secrets: not all of us, despite having earned our USPTO registration numbers, are truly gifted at drafting claims!  With that said, we have taken a keen interest in studying the specific issue of how practitioners employ the conjunctions “and” and “or” in patent claims.

For those of us of a certain age, we can probably remember the School House Rock series of musically-animated, educational short films produced by the American Broadcasting Company from 1973 to 1985.  One of the more well-known titles of the series, “Conjunction Junction: What’s Your Function,” sought to teach grade school children how to use conjunctions to connect words, phrases and clauses.  (For older readers seeking some nostalgia, or younger readers wondering what we are talking about, the three-and-a-half minute film can be found here.)  Fast forward a decade or two, now that we are registered patent attorneys, is a refresher course in order?  More specifically, when writing patent claims, have we mastered when to use the conjunctions “and” and “or”?  Have we even recognized the difference in the two?

Federal Circuit Puzzles Over Claim Construction Deference

The en banc Federal Circuit on September 13, 2013, heard oral argument on whether to overrule its en banc decision in Cybor Corp. v. FAS Technologies, Inc., 138 F.3d 1448 (Fed. Cir. 1998), and hold that claim construction can involve issues of fact reviewable for clear error, and that it is not entirely an issue of law subject only to de novo review.  Lighting Ballast Control LLC v. Universal Lighting Technologies, Inc., Fed. Cir., No. 2012-1014, 3/15/2013.

Lighting Ballast Control LLC (LBC) owns a patent (5,436,529) on control and protection circuits for electronic lighting ballasts commonly used in fluorescent lighting. The patent includes the term “voltage source means” in the following context: “voltage source means providing a constant or variable magnitude DC voltage between the DC input terminals.” LBC sued Universal Lighting Technologies, Inc. (ULT).

District Court Decision

On appeal is the district court decision that a person of ordinary skill in the art would understand the claim term “voltage source means” to correspond to a rectifier or other voltage supply device. It thus rejected ULT’s argument that the term invokes Section 112 ¶6 and that the claim is invalid for indefiniteness for lack of specific structure in the specification. A Federal Circuit panel reversed in a nonprecedential decision, concluding from a de novo review that “voltage source means” does invoke Section 112 ¶6 and that the claim is invalid for indefiniteness. That panel decision was vacated when the appellate court decided to consider the claim construction issue en banc.

Claim Construction: A Game of Chance at the Federal Circuit

Back in January, Scott Daniels pondered the question of whether patent applicants and patentees have a chance of success when appealing Patent Office rejections to the Court of Appeals for the Federal Circuit. The sad and candid truth is “not much of a chance.” As Scott pointed out, where the Federal Circuit is reviewing a validity decision from the district courts, the Federal Circuit reviews the claim construction de novo. The Federal Circuit also chooses not the most likely meaning, but the broadest reasonable meaning for disputed claim language. That is, the claim construction most likely to invalidate the claim in question. Now, we ask whether the same fate is likely to befall claims that are being asserted in a patent infringement action. Asked differently, does the Federal Circuit choose the claim construction most likely to lead to a conclusion of no infringement? Saffran v. Johnson & Johnson seems to suggest that the answer is sadly, yes.

Dr. Bruce Saffran (“Saffran”) is the owner and sole inventor of U.S. Patent No. 5,653,760 (the “’760 patent”). The ’760 patent describes an apparatus for spurring the repair of bone fractures by containing tissue fragments and tissue growth-promoting macromolecules within the fracture site. A single-layered sheet, which is selectively impermeable to the macromolecules and the tissue fragments, is affixed to the injured bone tissues. The selective barrier properties of the sheet prevent macromolecules from leaking out into neighboring tissues, thus concentrating the macromolecules at the fracture site.

In addition, drugs facilitating tissue regeneration can be bonded via hydrolysable chemical bonds to the inner surface of the single-layered sheet. This inner surface faces the injured tissues. Water molecules present at the fracture site causes lysing of the chemical bonds, which in turn releases and delivers the drugs into the fracture site. Bond lysis occurs at a constant rate, which enables the steady and controlled release of the drugs.

Heightened Judicial Deference for Patent Claim Constructions?

A critical look ahead at the en banc rehearing of Lighting Ballast Control LLC v. Philips Electronics N. Am. Corp. through the exemplary lens of a recent jury verdict in Syntrix Biosystems, Inc. v. Illumina Inc.

Patent litigants have long expected an appeal to follow nearly every jury verdict and that a key question (if not the key question) on appeal will be the district court’s construction of one or more disputed claim terms.  Syntrix’s recent infringement verdict against Illumina[iii] would be seen as no exception if not for what happened the very next day — the Federal Circuit’s decision to rehear en banc the panel’s decision in Lighting Ballast Control LLC v. Philips Electronics N. Am. Corp.[iv] to consider whether to reset the standard of review for claim construction, long recognized as a question of law reviewed de novo on appeal.

First, some background on Syntrix’s suit against Illumina.  Illumina sells BeadArray technology that includes BeadChips used for a broad range of DNA and RNA analysis applications by self-assembling microscopic beads into microwells on a substrate slide.  The beads are covered with specific oligonucleotides that act as a capture sequence in one of Illumina’s assays.  Two days before closing arguments, Illumina asked the district court to find, as a matter of law, that Illumina’s BeadChips could not infringe the Syntrix patent, US Patent No. 6,951,682.   The district declined this request and the case went to the jury.  The jury found that the claims were infringed, not invalid, and applied a 6% reasonable royalty against BeadChip sales of approximately $1.58 billion over the relevant period, awarding Syntrix $96 million in damages.

Harris Corp. v. Fed Ex: “Black Box” Claim Construction by Split Federal Circuit Panel Leaves us in the Dark

What a coincidence that the disputed patent in Harris Corp. v. Fed Ex Corp., decided by the CAFC last month, involved a plane’s black box technology!  Of course, both the majority and the dissent of this Federal Circuit panel scrupulously follow the interpretative roadmap of Phillips v. AWH, 415 F.3d 1303 (Fed. Cir. 2005) (en banc), but ultimately, neither the majority’s “entirely reasonable” explanation nor the minority’s views on “natural” and “intuitive” interpretation provide a convincing analysis.  We are left with the definite impression that the appellate judges, while giving lip service to Phillips, kept the real determinants of their thought process hidden inside the proverbial black box.


Over a dissent by Judge Wallach, Judges Clevenger and Lourie strictly interpreted the “antecedent basis” in the claims, resulting in a reversal of the trial judge’s claim interpretation, and a remand for him to reconsider his patent infringement judgment.

Harris’s patents cover methods and systems for using spread spectrum radio signals to send flight data from a plane’s “black box” to an airport receiver at the end of the flight.  The invention includes steps of generating, accumulating and storing flight data in the plane during the flight, followed by a step of “transmitting the accumulated, stored generated aircraft data” once at the airport.

Does the term “Invention” in the Specification Limit the Claims?

There are some that will tell you that the use of the term “invention” or “present invention” in the specification will limit the claims. This misguided belief suggests that merely using the word “invention” or the phrase “present invention” in the specification creates a problem for the claims. I have heard this numerous times over the years. Every time I hear this it is like fingers on a chalkboard.

The way the objection to the term “invention” or phrase “present invention” manifests itself is in a matter-of-fact manner. I am told: “You cannot use the term ‘invention’ in the specification because it is limiting.” As if not using the term “invention” or phrase “present invention” saves the drafter from the problem of to narrowly describing the invention in the specification. If only inadequacy of disclosure were so simple to solve!

The reality is that there is nothing wrong with using the term “invention” or the phrase “present invention.”  Moreover, the belief that avoiding those terms inoculates a disclosure from insufficiency issues is an extraordinarily simplistic view of what the law really says.  Those that believe this are missing for the trees, and may be unwittingly making the very mistake that they are so desperately trying to ovoid through the excising of specific terms from their vocabulary.

Against the Broadest Reasonable Interpretation of Patent Claims

Since at least the 1930s, courts have construed patent claims under examination according to their “broadest reasonable interpretation” (BRI).  In 1932, the Court of Customs and Patent Appeals, which preceded the Federal Circuit, provided a rationale for BRI rule as follows:

After a patent has issued, and it no longer is possible for the patentee to control the phraseology of his claims, the courts will so interpret them, if possible, as to protect him; but there is no reason as we many times have observed, why an applicant in the Patent Office should not draw his claims to cover his actual invention only. For this reason we have uniformly ruled that claims will be given the broadest interpretation of which they reasonably are susceptible. This rule is a reasonable one, and tends not only to protect the real invention, but to prevent needless litigation after the patent has issued.[2]

In the intervening eighty years, the CCPA and then the Federal Circuit repeatedly and vigorously upheld the BRI rule.  The Federal Circuit upheld the BRI rule after a challenge based on Markman, a major Supreme Court decision on claim construction.[3]  The Federal Circuit now applies the rule to all Patent Office proceedings (except those involving expired patents), including examination of applications, interference proceedings,[4] reissue applications,[5] and reexamination proceedings.[6]  The Patent Office cites a desire for a unitary standard as justifying application of the BRI rule to issued patents in postgrant review, where application of the rule is more controversial.[7]

The Mysterious Disappearance of Functionality Considerations in Apple v. Samsung Design Patent Claim Construction

On December 2, 2011 the district court in the Apple v. Samsung patent litigation issued a 65 page ruling [ii] denying Apple’s motion to preliminarily enjoin the U.S. sales of several Samsung products, [iii] based upon such products’ alleged infringement of three design patents [iv] and one utility patent, [v] owned by Apple.

In this ruling, the district court:

(1) recognized that “certain aspects of the design patent that are dictated by function” may limit the scope of such patent; [vi]

(2) listed elements contained in Apple’s design patents that are “dictated by function;” [vii]

(3) explained that it should “consider only the remaining aspects of the design in the infringement and anticipation analysis of the design patent” [viii] (citing Richardson v. Stanley Works, Inc. [ix] and OddzOn Prods., Inc. v. Just Toys, Inc. [x]);

(4) identified functional features in Apple’s design patents; [xi] and

(5) performed an infringement analysis of these design patents “in light of” its claim construction. [xii]

The above described claim construction and infringement analysis appear balanced and consistent with Federal Circuit authority cited by the district court.
