Another Bite For The Apple

In Apple v. Samsung (2015-1171), the CAFC once again demonstrated its lawless bias and caprice, reversing an appeals panel to reinstate the erroneous obviousness decision by the district court, finding for Apple against Samsung (no surprise there). Judge Reyna, in dissent: "The majority's en banc review is simply a do over."

Obvious Fabrication

In Arendi v. Apple, Google, Motorola Mobility (CAFC 2015-2073), the patent appeals board exercised illicit bias towards reexamination petitioners Apple et al by adding a missing limitation to a prior art reference and thereby declaring 7,917,843 obvious via "common sense." The CAFC reversed, not wanting the PTO's biases so obvious.

Patent law is the only law in the land where no evidence is required for condemnation. As the CAFC stated: "'Common sense' may only be applied when combining references that disclose all the required limitations. Though less common, in appropriate circumstances, a patent can be obvious in light of a single prior art reference if it would have been obvious to modify that reference to arrive at the patented invention." To be sufficiently obvious, the limitation in question has to be "unusually simple and the technology particularly straightforward. 'Common sense' - whether to supply a motivation to combine or a missing limitation - cannot be used as a wholesale substitute for reasoned analysis and evidentiary support, especially when dealing with a limitation missing from the prior art references specified."

Apple v. Samsung Saga

The long-running patent battle between Apple and Samsung took a comedic turn when the CAFC (2015-1171) threw out a $120 million judgment against Samsung for infringing Apple touch-screen patents that were obvious (8,046,721 & 8,074,172). Through bogus claim construction, the district court was also reversed in finding Samsung infringing Apple's 5,946,647 patent, which claimed an "analyzer server" that Samsung did not employ in its similar technology. The upshot: pathetic jurist work by Northern California Judge Lucy H. Koh.

Toxic Species

"To be sure, it is well-settled that a narrow species can be non-obvious and patent eligible despite a patent on its genus. An earlier disclosure of a genus does not necessarily prevent patenting a species member of the genus. But that is not the situation here." ~ CAFC in Prometheus Labs v. Roxane Labs (2014-1634)

Prometheus v. Roxane illustrates the turpitude of the US patent system. With 5,360,800, Prometheus patented a poison for treating irritable bowel syndrome. It its first run, the drug (Lotronex) was taken off the market after killing numerous takers. After adding restrictions for its usage, the drug was relaunched. "The number of severe incidents associated with Lotronex dropped, but the rate of adverse events did not change." Prometheus was then issued method patent 6,284,770, taking account in the claims the restrictions for medical application.

Prometheus sued Roxane for infringement. The courts found '770 obvious for double-patenting; "at best, the claims at issue are a combination of known elements, combined in a known way, to produce expected results."

ABT sued Emerson Electric for infringing 5,547,017, which claimed fan operations for an air-conditioning system. A judge and jury found the patent infringed, and awarded royalties. On appeal, the CAFC reversed (2014-1618, 2014-1700), finding the patent obvious "as a matter of law" in light of four references which disclose four claimed features, but do not combine them as '017 did, or even suggest such a combination. Lacking evidence, the CAFC surmised "the motivation or rationale for combining those references can be found in the nature of the problem addressed, if not directly from the disclosures of the references themselves."

Obvious After the Fact

A petition for rehearing en banc at the CAFC for a drug obviousness case (Bristol-Myers Squibb v. Teva - CAFC 2013-1306) was denied. What was remarkable was the inane confusion at the court. Judges Dyk and Wallach stated that "post-invention evidence" is rightly not allowed in considering obviousness. As Judge Newman observed: "Precedent is clear that the information and comparative data presented as evidence of nonobviousness need not have existed before the patent application was filed," noting the secondary consideration of commercial success, and citing several instances where evidence of unexpected results found later were considered relevant to obviousness. The CAFC continues to be an inexcusably pathetic excuse for a patent court: creating self-contradictory precedent and thereby failing to provide guidelines that the patent office and patent community may reasonably rely upon.

Judge and jury at district court found the patents infringed, and neither anticipated nor obvious.

The CAFC panel majority agreed with Google that "as a matter of law [the claimed invention] simply combines content-based and collaborative filtering, two information filtering methods that were well-known in the art." To rub it in the noses of unreasonable citizens who waste their time on jury duty: "no reasonable jury could conclude otherwise."

The CAFC continues its rampage against the rule of law. In Allergan v.

In dissent, Judge Chen notes: "This is not a situation in which there are a finite number of identified, predictable solutions. Rather, the single sentence in Johnstone actually proposes hundreds of thousands, or even millions, of variations."

The court today creates a new class of secret prior art, holding that a privately performed experiment, without publication or public knowledge or use or sale or inclusion in a United States patent application, is invalidating "prior art." Heretofore the role of secret prior art has been carefully circumscribed. The new general rule here adopted contravenes the policy and the letter of patent law, wherein inventors are charged only with knowledge of what is known or knowable as defined by statute, subject to special limited circumstances.

Many patents largely invalidate themselves. That comes in vice created between the prior art statutes (§102 and §103) and the written description requirement(§112 (a)).

But by not bothering with enabling disclosure of claimed features, a specification makes an tacit admission that it is merely claiming the prior art.

Outside the Box

The heart of the problem with patents lies with obviousness. Before Obzilla came to town, some scintilla of indication in the prior art had to exist before a claim could be considered obviousness. KSR v. Teleflex reset obviousness calibration to incorporate subjective evaluation; to read between the lines of prior disclosure. No longer being beholden to facts invariably opened the door to hindsight reasoning and adjudication bias, which has been a large part of the legacy of KSR. That withstanding, the problem remains how as to how far "common sense" and ethereal predictability should go as a matter of law. In C.W. Zumbiel v. Kappos, a CAFC panel doesn't go far enough, as the dissent points out.

Obzilla reaps another victim. Peter Droge and his cohorts thought they invented a DNA recombination technique. But a combination of a prior art patent and an article by two of the three applicants made the technique obvious, the patent board ruled, to which a CAFC panel agreed (CAFC 2011-1600). There was no argument over the evidence prima facie, only about what was reasonable. The inventors argued that similar work in prokaryotic cells "would not lead a skilled artisan to expect" the same result in eukaryotic cells. This argument was solidly backed by the prior art prokaryote workers teaching away: the relevant protein co-factors are present in prokaryotic cells, but not eukaryotic cells. But the CAFC is beyond reason in applying hindsight, and in backing the PTO if "a reasonable mind might accept as adequate to support a conclusion." In other words, facts just don't matter that much. To the CAFC and the USPTO nowadays, science is merely a matter of opinion. "'Obviousness does not require absolute predictability of success... all that is required is a reasonable expectation of success. In re Kubin, 561 F.3d 1351, 1360 (Fed. Cir. 2009) (citing In re O'Farrell, 853 F.2d 894, 903-04 (Fed. Cir. 1988))." Case-by-case subjectivity is now called rule of law.

In dissent, Judge Newman stepped on that sticky wad. "The district court erred in holding the '233... obvious on only part of the evidence, ignoring the evidence that supports unobviousness...

Clear & Convincing

When it comes to patent cases, the courts are biased towards mega-corporations, at granting undeserved credibility and in airing their gripes. But the license only goes so far. The Supreme Court has taken numerous patent cases since technology corporations starting whining about "junk patents" coming out of the USPTO last decade. The goal, as Justice Breyer put it, has been "to separate the sheep from the goats." Microsoft cried "goat" about i4i's patent that it infringed. So the Supremes brought in the livestock.

There's a crummy consistency to patent validity stupidity: failure to discriminate (which is symptomatic of the unaware generally). The cattle call "everything is everything" has a holistic ring, but it's more a rant for those too dim to discern between facets that matter. Post-Obzilla, such mental faux pas is common in USPTO examination, as applicants constantly experience. Arnold G. Klein was one of them.

Building an Invalidity Position

Most patents are junk. But proving that to a judge or jury is no easy task. The more technical the claimed invention, the more difficult it can be to convey the mapping between prior disclosures and patent claims to one of less than skill in the art. Prior art search is the first step to developing an invalidity position, and a most important step. But prior art search is best viewed as a cog used to build an invalidity steamroller. Fitting the parts together isn't always as simple as it may seem.

F. Scott Kieff may be witless in choosing article titles, e.g., "The Patent Process Run Amok", but he stirs some stimulating stew. In the i4i v. Microsoft case, a largely incompetent Supreme Court, grossly in thrall to corporate and government empowerment, feels obliged to again worry a detail of patent law that has no constitutional question behind it. What makes this case ironic is that the target i4i patent got bullet-proofed by reexam instigated by Microsoft, so the burden of proof to invalidate it is moot in this instance: the patent is valid, and Microsoft is res judicata in invalidating it. The safe bet is that the Supreme Court will jigger the validity calculator, but in their reasoning, how far they wander from logical rigor into a supreme wonderland of thought is, as always, the entertainment value.

The evidence herein is anecdotal, but the pattern is unmistakable: an incompetent BPAI decision is overturned by the CAFC. Glatt Air Techniques had one of its particle coater patents, 5,236,503, rejected over obviousness in reexam by a third-party requestor. The patent office can't tell the difference between prevention and a remedy. That pretty much sums up the Kappos regime's continuing failure of core competence for quality examination: rejection as prevention, leaving only appeal to the Court for remedy. Pathetic that the USPTO cannot recognize an invention, which thereby damages the sole mission of the patent office: to grant worthy patents.

Meanwhile, the patent office confirmed i4i's claims as valid over Microsoft-cited reexam prior art. The high court must scrutinize a system that is clearly broken: something is terribly wrong when some pip-squeak inventor or puny entity can extort money from mega-corporations raking in obscene cash flow, and have minion courts and bureaucrats let it slip by.

Andrew Chapman and David King had a patent idea "directed to divalent antibody fragments comprising two antibody heavy chains and at least one polymer molecule attached to the heavy chains in a site-specific manner on each chain... Chapman's invention involves joining together two fragments with an interchain bridge containing a polymer, thus achieving a circulating half-life that is intermediate between that of an individual fragment and a whole antibody."

Why the Hawk

A friend and client, India born, was telling me about the different prior art search firms he had used. "The Indians are cheap, and you get what you pay for. They find something and they quit. They know nothing about litigation, or U.S. patent laws. They have no concept of story art. They just throw a piece or two of art over the wall to you and declare victory. The European Patent Office searches like examiners. What else would you expect? They do okay for a superficial search, but for a litigation search, they are incomplete. Like the Indians, the EPO also just cites references."

ResQNet sued Lansa in 2001 for infringing five patents related to terminal emulation. Lansa found art, two unpublished user manuals for a software product called Flashpoint, that it argued anticipated one of the asserted patents, 6,295,075. But the district court wouldn't admit the art as public, and hence not legally prior art. Lansa tried to argue that NewLook 1.0 anticipated '075 by being sold more than a year prior to 075's filing date, but NewLook 1.0 "lacked an essential limitation," so was not found to be invalidating prior art. Alas for Lansa, a later version of NewLook was found to have the feature, and so infringed. Then there were the issues of damages, and sanctions....

Abbott appealed the trial judge's jury instruction over the meaning of anticipation.

Becton, Dickinson and Company threw down a declaratory judgment (DJ) action on competitor Abbott over a couple other patents. Abbott countered with a suit that also asserted '551. Weak move. The DJ worked: summary judgment of non-infringement and anticipation of numerous claims of one patent.

"Although statutorily authorized to triple the jury's damages award because of Microsoft's willful infringement, the district court awarded only $40 million in additional damages. It also granted i4i's motion for a permanent injunction." The inevitable appeal, widely expected to go more Microsoft's way than not, did not.

Patent Contraceptive

The danger lurking in obviousness is hindsight reasoning. A breakthrough becomes predictable. In hindsight, you/they/whoever should have seen it coming. Bayer's oral contraceptive, Yasmin®, had unexpected performance. The active ingredient, drospirenone, readily degraded in an acidic environment like the stomach. Grinding it to itty bits, i.e. micronizing, should have exacerbated the problem. So, logically, you'd coat it, to try to make more of the drug bio-available. Bayer found out that coating wasn't necessary, and micronizing didn't decimate bioavailability in an acidic environment nearly as badly as previously thought. That much was obvious. But only in hindsight.

Emtrak, over 5,097,421, claiming a system for tracking articles in a manufacturing plant, namely semiconductor wafers.

Anticipation Without Obviousness

Cohesive Technologies sued Waters for infringing patents claiming liquid chromatography. A jury found the patents not obvious over "seven separate prior art references." In a 2-1 appeal decision, the CAFC remands because seven patents that singularly or in combination didn't render the patents obvious, to which all agreed, but the appeals court majority thought they might anticipate. Huh? Obzilla obviousness nothing to straight-laced anticipation? Surely they jest. Alas, no. The dissent was a scathing straight arrow.

In a typical drug patent case, Impax wanted to barge in on Aventis' patented treatment for Lou Gehrig's disease (ALS), vis-à-vis 5,236,940, so Impax filed an ANDA, then a DJ motion, charging invalidity and unenforceability for inequitable conduct. The judge didn't buy it. Appealed. Remanded. District court judge still didn't buy invalidity, the only charge left to Impax (inequitable conduct being a regularly ginned accusation that seldom sticks). On second and last appeal, a lesson on prior art burden shifting, and the difference between anticipatory and enabling prior art.

From the appeal are mined jewels of anticipation, including the irrelevance of "teaching away," and applying the gauze of inherency: "a prior art reference may anticipate when the claim limitation or limitations not expressly found in that reference are nonetheless inherent in it." Mere mention is insufficient: "the fact that a claim limitation may be present in a reference does not establish that the reference inherently discloses that limitation."

Obviousness Vampire

Granting patent protection to advances that would occur in the ordinary course without real innovation retards progress. - KSR

All other users having taken licenses, PharmaStem sued the remainder six companies for infringing two patents related to treatment for compromised blood and immune systems. In yet another 2-1 split decision, a CAFC majority finds obviousness where none had been found before (CAFC 05-1490) -

The inventors merely used routine research methods to prove what was already believed to be the case. Scientific confirmation of what was already believed to be true may be a valuable contribution, but it does not give rise to a patentable invention.

- while the dissent finds the hindsight demon unleashed by KSR a vampire, sucking the lifeblood from a deserved patent.

The court's approach reflects misperception of the scientific process as well as the patent purpose. Scientific methodology usually starts with a hypothesis based on what is already known; the record shows that several scientists mentioned the idea of rebuilding destroyed blood cells. However, none achieved this long-sought goal, and the record shows the extreme skepticism concerning even the possibility of this achievement. Nonetheless, my colleagues deny the value of this long-sought result. Instead, my colleagues simply reweigh selectively extracted evidence, ignore the actual peer response and acclaim at the time these inventions were made, reject the testimony and admissions of the defendants, and use present knowledge of the inventors' success to find that it was obvious all along.

Upside Down Down Under

In a unanimous decision Wednesday, recognizing the value of patent protection for incremental invention, the Australian High Court ruled in Lockwood v Doric that "a "scintilla of invention" remains sufficient in Australian law to support the validity of a patent." "'Obvious' means 'very plain'." Most notably, unlike the arrogantly parochial U.S. Supreme Court, relying upon its own cogitations and no other, the Australian High Court draws from understanding and precedent worldwide.

Ordinary Skill in the Art

In 1941, the Supreme Court required a "flash of genius" for a patent to stand. Congress lowered that high standard in 1952 to non-obviousness to one with "ordinary skill in the art." Now again, more than interpretation, the Supreme Court exceeded the law in its KSR v. Teleflex decision. In its own flash of unpatentable creative insight, SCOTUS redefines the statutory "person having ordinary skill in the art" into someone omnificent and possessing comprehensive technical expertise.

Common Sense Turns Wily

The echo of SCOTUS KSR, the domino effect of invalidation by obviousness, has begun. For example, translating a mechanical toy to an electronic version with additional features is old hat. In Leapfrog v. Fisher-Price & Mattel, the CAFC upholds a district court ruling of obviousness that's a real stretch. An electronic child learning toy is obvious by combination of a mechanical version disclosed in a prior art patent, a product with a "slightly different mode of operation," and, to get the screen reader, well, there were screens around; no particular prior art need be cited. "Substantial evidence of commercial success, praise, and long-felt need" yield no counterweight "given the strength of the prima facie obviousness showing."

In its landmark decision of KSR v. Teleflex, reversing the appeals court, the Supreme Court has broadened the interpretive scope of 35 U.S.C. § 103(a), the obviousness clause. Patentable subject matter is thus constricted. In the large, in light of the ruling, a known combination of elements are only patentable if their combined functionality yields the unexpected. What was once impermissible hindsight is now permissible.

Uncertainty is Not Obvious

Indeed, it often requires as acute a perception of the relations between cause and effect, and as much of the peculiar intuitive genius which is a characteristic of great inventors, to grasp the idea that a device used in one art may be made available in another, as would be necessary to create the device de novo. And this is not the less true if, after the thing has been done, it appears to the ordinary mind so simple as to excite wonder that it was not thought of before. The apparent simplicity of a new device often leads an inexperienced person to think that it would have occurred to any one familiar with the subject; but the decisive answer is that, with dozens and perhaps hundreds of others laboring in the same field, it had never occurred to any one before. The practiced eye of an ordinary mechanic may be safely trusted to see what ought to be apparent to every one. - C & A Potts & Co. v. Creager, 155 U.S. 597, 607-08 (1895).

The Salt of Obviousness

Apotex's successful appeal against Pfizer (CAFC 06-1261) points at the near chaotic state of anticipation in case law, ad hoc consideration of what constitutes an obvious innovation, as opposed to a patentable invention. In the case of Pfizer's Norvasc compound, invalidity challenges had been rejected by three different district courts before the CAFC pulled an upset, declaring the mixture obvious. The court elucidates where presumptions lie with regard to obviousness, what constitutes "reasonable expectation of success" has to do with what would have been expected, that the threshold of "undue experimentation" is beyond routine testing, that "obvious to try" isn't good enough, and that predictability has nothing to do with it (huh?). "[P]atentability is not imparted where ‘the prior art would have suggested to one of ordinary skill in the art that this process should be carried out and would have a reasonable likelihood of success.’" Creating a formula to promote litigation, to the appeals court, obviousness is like pornography: you only know it when you see it. And, like good pornography, you better look it over carefully.

Pressure Drop

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.

Mr. Egbert gave his future wife a corset with a feature that he patented two years after she began wearing the corset. Did his lady wearing his custom corset constitute "public use", and thus invalidate his patent? If a company develops a recombinant DNA biotechnology that it uses within the company more than a year before filing a patent, but doesn't sell a product using the technology, is that "public use", thus invalidating the patent under 35 U.S.C. § 102(b)? In Invitrogen v. Biocrest (CAFC 04-1273) we find out.

On-Sale Bar Fine-Tuned

The Federal Circuit Court of Appeals (CAFC) has tuned the on-sale bar standard for 35 U.S.C. §102(b) in its ruling of Electromotive Division of GM v. Transportation Systems of GE (CAFC 04-1412).

The relevant portion of §102(b), commonly called the on-sale bar, provides for invalidating a patent if "the invention was ... in public use or on sale in this country, more than one year prior to the date of the application for patent in the United States".

Mettling With Obviousness In Metal

Kenneth Harris and Jacqueline B. Wahl were trying to get a patent "claiming a nickel-based superalloy for turbine engine blades that experience high temperatures." Rejected by the patent office appeal board as obvious under 35 U.S.C. § 103, they pressed on, all the way to the Federal Appeals Court (CAFC) (04-1370).

Handling §103 Rejections

It’s not unusual to receive a 35 U.S.C. §103(a) combination rejection applied with little more than the glib dab of glue: "it would have been obvious". Examiners often implicitly rely upon art class as a binder for justifying combination. Convenient selective quotations are applied for features that wouldn’t mesh if looking at the art holistically. Application out of context is a similar flaw: applying a prior art feature used in a specific way to a claimed invention using a similar feature differently.
