Synthes went after Spinal Kinetics over 7,429,270, which claims an artificial spinal disc. In dissent over claim construction and written description, where the CAFC affirmed the district court's damning the patent, fledgling Judge Taranto demonstrates the easy corruption of U.S. courts.

The caprice of the courts is one of two main reasons that the U.S. patent system is terminally broken. The other cause is of course the USPTO: a cesspool of incompetence, as evidenced by how few granted patents legally claim actual invention, and the multitude of applications that linger in examination for up to a decade or more. ePlus v. Lawson illustrates how unpredictable the courts are, as well as how unjust the CAFC is.

35 U.S.C §112 ¶1 requires that claimed invention be reduced to practice; that is, described in the patent specification such that one of skill in the relevant art area would be able to read the patent and implement the invention. Without this requirement, shambolic specifications would confer patents on rough ideas rather than practical inventions. Hence, evisceration of the written description requirement would make a mockery of the law, and the very purpose of the patent sanction. The courts don't see it that way.

The CAFC again limits patent protection without basis in statute. Under government grant, MIT developed a device, usable as a sensor or computer memory, employing quantum mechanical effects; patented as 5,629,922. Exclusive licensee Masgil and MIT launched an enforcement campaign against 20+ disk drive makers. In summary judgment, the district court found '922 not enabled, for the sin of being too valuable a patent. A CAFC panel affirmed.

5,875,435 claims an automated accounting system. '435 owner Noah Systems sued Intuit for infringement. Intuit got the litigation stayed pending reexam. Reexam by "the PTO confirmed the patentability of the original claims of the '435 patent and determined that new claims 19-56 were patentable." With litigation restarted, Intuit sold the district court on the illicit idea that the claimed "access means" were indefinite under §112 ¶2 "because the specification disclosed no algorithm by which the computer was programmed to perform the function asserted in the claims." By law, that failing would be written description, §112 ¶1. But the fix was in, and that was all that mattered. The district court ignored that the claimed "access means" referred to entering a passcode, which was well-documented in a figure and written description, as court documents showed. Affirmed on appeal. (CAFC 2011-1390). One more chip on a mountainous pile showing blatant patent court corruption favoring well-regarded companies over patent holders.

5,507,412 claims a system to deliver fluids from multiple sources into a patient's body. An adjusting means is claimed to influence the fluid flow from each source. There is a claimed programmable control means coupled with the adjusting means. In the disclosure, the functions of what the control device does are variously mentioned, but how the control device functions is never described. '412 owner Ergo sued CareFusion for infringement. Under the influence of 112 ¶ 2 by way of § 112 ¶ 6, the "district court held that the 'control means' terms are indefinite for failure to disclose corresponding structure." The CAFC affirmed. (CAFC 2011-1229). Should have been euthanized by 112 ¶ 1. The claim was definite enough, but lacked written description.

6,879,830 goes to "a method for handing over a link between" base stations for a mobile phone. Actually, a mobile phone is claimed, an apparatus, but where a claimed networking method must be performed for the claimed handover to occur. Thus the meat of the claims are of a method, though the claim is of an apparatus, which is a transgression of §112 ¶2, indefiniteness, for mixed claim types, vis-à-vis IPXL v. Amazon. So this ruling is easy. But not so fast. Consistency is the hobgoblin of small minds. As there are no small minds on the CAFC, there is no need for consistency.

In the claim construction dust-up, the district court's grasp of means-plus-function needed some modernizing, for missing the necessity of "means" in proclaiming that § 112, ¶ 6 applied.

Described and Enabled
35 U.S.C. § 112, ¶ 1 has two requirements: 1) a written description so as to enable any person skilled in the art to make and use the claimed invention; 2) a best mode "set forth." The first requirement is of a piece. Any description that falls short of enablement is inadequate. But case law has grown a thicket of complication, essentially bifurcating adequate written description from enablement, even as the statutory inquiry is singular. The CAFC majority opinion in Boston Scientific v. Johnson & Johnson muddies the bifurcation, albeit flying under the banner of written description, not enablement. The partial concurrence disliked the mud, and the banner.

For that, "all claims were invalid for lack of written description under 35 U.S.C. § 112" in summary judgment, along with noninfringement. Gasping for air, LMA appealed. At issue was claim construction, and whether the inventor had acted as his own lexicographer. "A patentee may act as its own lexicographer and assign to a term a unique definition that is different from its ordinary and customary meaning; however, a patentee must clearly express that intent in the written description."

Summary judgment of infringement for claims 1 and 2, and dismissal of "all of Medtronic's 35 U.S.C. § 112 defenses" led to stipulated capitulation by Medtronic, setting up a trial on damages and obviousness. SSI was going for lost profits even though it didn't sell or make any device covered by '071. But SSI's sister companies did. SSI was allowed to amend its complaint to include them. The jury found '071 not invalid, and willfully infringed, to the $5.7 million in lost profits, and an 18% reasonable royalty on $9.1 million in infringing sales. Whereupon the district court doubled the damages and awarded attorneys fees. Adding insult to injury, the court entered a permanent injunction. All that left Medtronic a lot to appeal. And some of it was appealing to the CAFC.

RE39,050 was called by the court "the Low Dose Patent." Generic drug manufacturer Teva embroiled itself into a patent fight with Lily by filing an ANDA with the FDA to make generic versions.

The district judge then tacked on prejudgment interest, an accounting for interim sales, and "ordered the parties to negotiate the terms of a royalty that would apply to the accounting and to post-judgment sales."

6,919,373 is a drug patent that claims a treatment regime for folks with short attention spans. The claims specifically go to "an ascending release rate over an extended period of time." A bench trial found '373 not infringed, and "invalid for lack of enablement because the specification does not enable the full scope of claim 1, which covers both osmotic and non-osmotic dosage forms." Enablement hinged on whether undue experimentation was needed to deliver an oral dosage that didn't rely upon osmosis. The district court found too much tinkering was needed based upon scant disclosure, hence the claims were not enabled. Appeal found the same deficit of attention.

The district court outcome was invalidity by indefiniteness for '920 asserted claims, and noninfringement for a few claims of '076 and '151 for Shure's product that used a straight nozzle. A jury found the '076 and '151 patents "not invalid and infringed by Shure's products both with a barb and with a straight nozzle," and awarded $4.6 million in damages. Post-trial, the judge granted a portion of Shure's noninfringement motion, but left the patents valid. That went to appeal, as well as denying Shure noninfringement JMOL for its barbed nozzle earphones, and denying laches. Hearing Components wanted another hearing on the claim term "readily" turning its claims deaf to definiteness.

Lonza attacked priority date by way of parent enablement; fought the finding of infringement via questionable testing; argued prior invention with uncorroborated evidence; and tried to clobber the claim construction using the file wrapper as a club.

There's a claimed "means for comparing the detected incoming telephone number with said directory of telephone numbers to identify the party associated with the incoming call number." Not exactly rocket science there, even back in 1988 when the patent was filed. Sued for '496 over its iPhone, Apple wanted summary judgment indefiniteness, for failing to disclose an algorithm for comparing. Unconvinced, the Massachusetts magistrate judge on the case blew that off. Tell it to the jury, she wrote.

In Bilski, the rogue CAFC ruled on the wrong grounds, and in the process warped the law, by setting in stone what were intended as guidelines. To afford case-by-case consideration, a court writes itself wiggle room. Instead, the CAFC tends to sew itself straightjackets.

Bilski's claims are neither useful nor definite, and hence non-patentable under §101 and §112 ¶2.

Here's how SCOTUS should shoot down Bilski and claims of its ilk - recognize the intertwining of §101 and §112 ¶2, that an ill-defined process is a strong indicator of indefinite usefulness, and hence unpatentable subject matter.

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.

Lame Blaming About Claiming
CAFC Judge Plager recently mused out loud about claim construction, most strikingly, his and the court's technical incompetence.

Dr. Kenneth Alonso lost his appeal for patenting a cancer treatment because, while he claimed a genus, he had only disclosed some species, and insufficiently so. Disclosure coverage is at issue when the claimed genus is wide-ranging, and the disclosed species may not be fully representative. "A patentee of a biotechnological invention cannot necessarily claim a genus after only describing a limited number of species because there may be unpredictability in the results obtained from species other than those specifically enumerated."

The claims, in the form of means-plus-function, were invalidated because they lacked specification support. The road to that invalidity is § 112 ¶ 2, indefiniteness, not § 112 ¶ 1, the written description requirement. Patents by Mark Ogram, inventor and patent attorney, turn Shakesperean: "hoist with his own petar." At least he only has himself to blame. Also herein, the arrangement requirement for anticipation.

Technology Licensing (TLC) went after Gennum for infringing a family of patents going to video synchronization. The most interesting facet of this case pivoted on patent priority date. With a continuation-in-part (CIP), a claim is entitled to the effective filing date of an application that provides written description support for the claim. The effective filing date becomes an issue when invalidating prior art exists between the initial parent filing date and the filing date of a later CIP.

5,126,270 and continuation 6,017,745, claim turning bacteria into enzyme factories. Patent owner Carnegie Mellon University sued Roche for infringement. Roche got a claim construction that led to summary judgment of non-infringement, and invalidity for "lack of written description in light of... Regents of University of California v. Eli Lilly", with Gentry Gallery v. Berkline riding shotgun. On appeal, the CAFC met the written description requirement on meeting the written description requirement. And relegated to the unremarkable the earlier § 112, ¶ 1 ruling, Gentry Gallery.

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.

Fargo Electronics sued IRIS for infringing 5,755,519 and 6,152,625, which claim a ribbon type sensor for a printer. IRIS sells replacement ribbons compatible with Fargo printers. A couple of claims fell on the reasonable repair doctrine. Incompetent prosecution, resulting in indefinite claims, killed the rest of the assertion.

Most junk patents are created by incompetent prosecutors, with an assist from incompetent examiners granting bad claims. Example in point - Arthur A. Collins got a couple of junk patents: 4,701,907 and continuation 4,797,589. '907 sunk by §112 ¶2, an unconstruable claim term. '589 down on non-infringement over missing a limitation, and claims "invalid for improper reexamination amendment." Appeal offered no real reprieve.

John Wong got 5,568,779 for TALtech, claiming a seam for wash-and-wear dress shirts that don't pucker when laundered. Wong didn't disclose all the prior art he knew of, including the prior art that was the inspiration for his invention. The district court found inequitable conduct. The appeals court starches that shirt: "If the material is cumulative to other disclosed material, as a matter of law, the inventor is not obligated to disclose it." And, a lesson on best mode.

21st Century Schizoid Everyman
Sitrick v. Dreamworks stirred muddy water. Marc Brown of McDermott Will & Emery worries: "Without realizing it, a recent series of Federal Circuit decisions has established a standard for enablement that may arguably be higher than any patent can meet." Is the concern justified? Why hasn't enablement had a head-on collision with its alter ego behind obviousness and the doctrine of equivalents?

They killed the bunny patent. It's enough to make you cling to your guns and religion. Energizer tried to zap Chinese battery makers using the ITC, but the ITC pulled the plug. Twice. On appeal, a non-precedential decision, owing to all-around discord in the panel. A badly drafted claim loses its juice on antecedent disconnect.

PowerOasis had a dysfunctional family of patents, notably 6,466,658 and 6,721,400. The patents claim telecommunications access via a vending machine. PowerOasis went after T-Mobile, who successfully broke the family lineage, that these CIP children weren't entitled to their parent's birth date. On appeal, the written description requirement is recited as part and parcel of determining priority date for a CIP. There is no presumption that a CIP is entitled to an earlier filing date.

An Algorithm Shy
Australia-based Aristocrat threw away money getting gaming machine patent 6,093,102, and then threw away money trying to enforce it. Means-plus-function with no unction. From the CAFC, a crash course in means-plus-function claims for computers: the claimed function is bounded by the specifically disclosed algorithm. Lacking an algorithmic tether, a means-plus-function processor claim is indefinite.

Mixed Claim Types
Both the USPTO and the courts proscribe claims mixing statutory claim classes as both unpatentable subject matter under §101 and indefinite under §112 ¶2. But, as is often the case with claim construction, the line may seem fuzzy. Herein a guide.
February 22, 2008
For now, the CAFC retains a polite fiction: "We review claim construction de novo on appeal. Cybor Corp. v. FAS Tech., Inc., 138 F.3d 1448, 1456 (Fed. Cir. 1998) (en banc);" de novo because claim construction is considered a matter of law, not a factual inquiry. In today's Aristocrat nonprecedential reversal and remand, summary judgment of indefiniteness in claim construction was ruled in error because "genuine issues of material fact remained pertinent."

Black Hole of Enablement
Enablement was spun into a black hole of uncertainty by the CAFC in Sitrick v. Dreamworks, which expanded the enablement requirement at least to the degree that an accused product must be a disclosed embodiment for a claim to be enabled. Hal Wegner: "In essence, Sitrick voids any generic claim that is fully enabled as to a preferred embodiment, but includes other embodiments not yet enabled." Can a patent now be invalidated by showing any undisclosed embodiment within the scope of a claim?

David Sitrick sued movie makers DreamWorks and Warner Brothers for infringing 5,553,864 and 6,425,825, which claim integrating a user's voice or imagery into a pre-existing video game or movie. The district court process was fitful, but the judge granted summary judgment: invalidity for lack of enablement for movies, though having no problem with enablement for video games. The CAFC affirmed.

Trimed sued Stryker for infringing its bone fracture fixer patent: 5,931,839. Claim construction fractured the assertion, resulting in a noninfringement summary judgment. Trimed had the misconstruction mended on appeal. The spat was over the structure of a hole.

Halliburon sued M-I for infringing 6,887,832, claiming oil drilling using fragile gels for drilling fluid. The problem was that "fragile gel" was ill-defined, leading to invalidity under 35 U.S.C. § 112, ¶ 2. Irresolvable ambiguity to one skilled in the art is the yardstick of indefiniteness. The CAFC pens a claim construction classic on delineation of claim term definiteness.

Paul Lew and Jason Schiers dreamed up a wheel hub with a clutch, for bicycles, which allowed free wheeling when not pedaling, but instantly engaged when pedaling. The torque transfer was "through a multitude of ball bearings." Lew got 6,644,452 for it. Prosecuting the continuation, he canceled his original claims and submitted a substitute specification, essentially identical, except replacing "ball bearings" with "curved members," and "pockets" with "slots," both new terms. The examiner balked.

6,593,318 & divisional 6,593,320, owned by Par Pharmaceuticals, "relate to stable flocculated suspensions of megestrol acetate and methods for making such suspensions." Par's patented work sprung from trying to design around 5,338,732, owned by Bristol-Myers Squibb. In the event, Par sued Roxanne for infringement. Roxanne got a district court summary judgment of invalidity via lack of enablement (§112 ¶1) because the claims were so broad. Par futilely appealed.

Means claims have been problematic for years; many prosecutors avoid the means-plus-function claim form altogether, as means claims are tightly bound to the specification. Courts have often limited doctrine of equivalents application for means claims, even though DOE is statutorily bona fide. But sometimes there's an even more fundamental problem. Maurice Mitchell found out what that was.

ATI sued a bevy of car makers for infringing 5,231,253, which claimed a velocity sensor for detecting side impacts. The defendants drove a frontal assault: that the claims were invalid for failing to meet the written description requirement of 35 U.S.C. § 112, ¶ 1, and lack of enablement. The patent crashed.

William Young patented a surgery procedure for removing cat claws. In suing Lumenis for infringing, the district court ruled in summary judgment the asserted patent indefinite under 35 U.S.C. § 112, ¶ 2, over the claim term "near," and unenforceable for inequitable conduct, in part because Young was tardy giving the patent office a litigation deposition during reexamination, though timely enough for the examiner to consider its import. Young successfully appealed. (CAFC 06-1455)

MicroStrategy sued Business Objects for infringing three patents related to decision support software. In an affirmation of what Hal Wegner called "an unforgiving trend of finding against a patent owner’s sloppy use of the English language," summary judgment of noninfringement and invalidity were upheld (CAFC 06-1320).

Biomedino appealed an indefiniteness ruling for claims of its asserted 6,602,502 against Waters Technologies. '502 went to detecting psychoactive drugs in the blood. While the courts differed on the applicable paragraph, Biomedino's patent trip turned out to be a bummer.

Liebel asserted four patents against Medrad. In the second appeal of the litigation, the appeals court (CAFC 06-1156) concurs with a district court ruling that Liebel had not enabled broadened claims in two of the four patents, thus invalidating the patents under 35 U.S.C. § 112, ¶ 1. Liebel had broadened its claims to ensnare Medrad, and so tripped itself up over its own greed. The full scope of claims must be enabled. As the CAFC tooted: "The motto, “beware of what one asks for,” might be applicable here." Concurring again with the district court, the other two asserted patents were found invalid by prior art; cited prior art; in summary judgment, with no factual dispute.

Liquid Dynamics (LD) sued Vaughan Company for infringing 5,458,414. In the first round, LD successfully appealed an erroneous claim construction. Upon remand, a district court trial found Vaughan willfully infringed, and then in a subsequent bench trial, trebled damages and awarded attorneys fees because of "Vaughan’s behavior as a litigant," as well as then issuing a permanent injunction. Naturally, Vaughan appealed (CAFC 05-1105).

Claim Scope Per Disclosure Redux
LizardTech got its wavelet compression patent dubbed by the CAFC (05-1062 panel) for overreaching in its claim beyond its specification, when only one embodiment had been disclosed. So, desperate, LizardTech appealed for an en banc hearing (05-1062 en banc); request denied. But in its snub, the CAFC put on a little fireworks show between the ruling majority and dissenters.

IPXL Holdings assertion of patent infringement against Amazon.com for its one-click checkout didn't click with the courts. What especially missed the click track was tacking a method onto a system claim. MPEP § 2173.05(p)(II): "A single claim which claims both an apparatus and the method steps of using the apparatus is indefinite under 35 U.S.C. 112, second paragraph."

Fisher-Price sued Graco Children's Products, and its parent, Newell Rubbermaid, for patent infringement regarding a collapsible infant swing (6,520,862). The district court threw the case out in summary judgment owing to the asserted claims being indefinite. The appeals court (CAFC 05-1258) had a different swing, giving the patent holder the benefit of the doubt in readily understood technology.

And he tried to put the squeeze on Wadsworth Manufacturing for infringement, but couldn't loop them in district court. The CAFC said that the lower court ruling was bull (04-1597).

Overcoming §112 ¶ 2 Rejection
35 U.S.C. §112 ¶ 2: "The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention."
Process/method claim rejections may be off-base if the rejection complaint is that the claimed method is not enabling, or even that the claimed method is not self-sufficiently comprehensible.

§112 Rocket Science
Space Science/Loral received a patent (4,537,375) for saving fuel in rocket thrust maneuvers to maintain orientation and attitude of a satellite in space. Gravitational tugs by the earth, sun, and moon require positional adjustments. Things just don't sit still in space.
The claimed maneuver was a two-step process: fire thrusters once, consider what that did, then adjust if necessary. Lockheed convinced the district court in a summary judgment motion that there was not sufficient disclosure of the considering and adjusting portions of the claim. The Court of Appeals fired their thrusters with a different attitude.
