Single Amputation Kills Whole Family
Ohio Willow Wood came up with some patented designs for cushions over amputated limbs. One was amputated during litigation-related reexam. That was enough to effectively kill the whole family. "Collateral estoppel protects a party from having to litigate issues that have been fully and fairly tried in a previous action and adversely resolved against a party-opponent. Our precedent does not limit collateral estoppel to patent claims that are identical. Rather, it is the identity of the issues that were litigated that determines whether collateral estoppel should apply." (CAFC 2013-1642)

The CAFC has become so inured to blithe invalidation of patents that the finer points of law no longer matter. In a dust-up between rivals Hamilton Beach and Sunbeam, HB's 7,947,928 slow-cooker patent was invalidated under the on-sale bar of § 102(b). Yet, as the dissent pointed out, the supposed invalidating action was not the requisite commercial offer for sale.

Blind Pig & The Acorn
The CAFC concocted the "substantial evidence" standard so as to ignore appeals from PTO Board rejections. Rare is the instance when the appeals court will exercise otherwise. But in Smith & Nephew v. Synthes (CAFC 2012-1343), as part of the CAFC's proclaimed war on patents, a panel took the opportunity to invalid a patent, via excruciatingly detailed analysis, that the Board had wondrously found non-obvious. The claimed invention was clearly an incremental improvement at best. And it looks like the PTO Board was simply asleep at the switch on this one.

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)). Patent backgrounds typically confess their technological pedigree. This is explicit admission of prior art. But by not bothering with enabling disclosure of claimed features, a specification makes an tacit admission that it is merely claiming the prior art.

In re Chevalier (CAFC 2012-1254) is a garden-variety affirmation of obviousness, where hindsight motivation was used to combine prior art references to solve the problem of the claimed invention. "The Supreme Court stated in KSR that "when a patent claims a structure already known in the prior art that is altered by the mere substitution of one element for another known in the field, the combination must do more than yield a predictable result.'" Further, under its recent "substantial evidence" standard, the CAFC continues to make clear that some egregious error must be evident for it to give any traction to denying the USPTO its purview.

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.

Transocean got patents on an oil drilling rig, particularly the drill bit.

But on the second appeal, the CAFC reversed itself, that the patents weren't obvious, because Transocean had commercial success.

The core concept behind rule of law is that evidence is required to make a determination. Rule of law is turned into a sham when courts have the power to arbitrarily decide matters based upon their own bias. That sham is exactly what patent law (using the term "law" loosely) became with the 2007 Obzilla ruling by the Supreme Court (KSR; Obzilla a portmanteau for the Godzilla of obviousness). This week's episode involves a hand-waving incantation of obviousness by the ITC, affirmed by the CAFC...

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 pursuit of a "crossbar arithmetic processor" patent, Blaise Laurent Mouttet provided another lesson in the way of Obzilla: any possible combination of known features is not patentable, even when the prior art technologies are not compatible. Mouttet envisioned an arithmetic processor using a crossbar structure. He cited a prior art publication, Das, that disclosed a "nanoscale crossbar array with molecular switches." The examiner found Falk (5,249,144), which taught a "programmable optical arithmetic/logic device," and Terepin (4,633,386), an analog-to-digital (A/D) converter. The examiner put them together to fabricate Mouttet's claimed invention, a rejection affirmed by the PTO appeals board and CAFC.

Wrigley sued Cadbury over its menthol gum patent, 6,627,233. Cadbury counterclaimed with 5,009,893. Wrigley was found not chewing into '593 (noninfringement). Then Wrigley got hit a lick on its own mentholated stick. '233 was found anticipated and obvious; judgment affirmed on appeal (CAFC 1201-1140,-1150; precedential). 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... The district court also granted summary judgment of invalidity on the ground of anticipation, not relying on any reference cited for obviousness, but relying on a different reference that does not show the claimed combination at all, but merely presents the ingredients on lists." Rule of law is gummed up at the CAFC (and in courts across the country). Chew on that.

Sadly for the co-conspirators, a few on the court inclined to rule of law continue to speak out. Judge Newman, in dissent, is one: "The Hyon procedure and its effects are not shown or suggested in any reference, despite the long history and extensive scientific studies of all forms of polyethylene...

In a close-call case, Otsuka v.

"In keeping with the flexible nature of the obviousness inquiry, the reason or motivation for modifying a lead compound may come from any number of sources and need not necessarily be explicit in the prior art." The ruling also gives a nuanced reading of nonstatutory double patenting. Here too, the subjectivity of "unpredictability" plays a lead role.

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.

Tessera designs semiconductors, and thereby manufactures patent litigations. This episode emanates from the ITC, in an action against several parties: Spansion, Freescale, ATI, STMicro, and Qualcomm. Motorola settled. 5,852,326 and 6,433,419, going to a particular semiconductor packaging, were asserted. After typical bureaucratic discord, the ITC found the patents valid and infringed. The inevitable CAFC appeal inevitably went to claim construction, infringement, and validity.

Lay That Burden Down
The black-robed toads who feel beholden to uphold the powers that be are taking it upon themselves to look at a more open season for patent killing. i4i squeezed a $290 million jury award from Microsoft for a feature in Word that few users knew existed, let alone use: customizing XML using metacodes (which, technically, is like herding cooties). The CAFC affirmed willful infringement, enhanced damages, permanent injunctive relief, and validity. 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.

AstraZeneca sought and got a preliminary injunction against Apotex, which was hankering to launch a generic version of the asthma drug Pulmicort. Apotex did manage to invalidate "kit" claims of asserted 6,598,603 and 6,899,099. Appeal left things as at district court, with dissent on the injunction, owing to a different take on validity.

Richard F. Schwemberger filed an application for a surgical stapler which the patent office found an obvious combination of two prior art references. We're talking pre-KSR obvious (not that the PTO or CAFC bothered with such legal finesse). Which makes Schwemberger not exactly patent savvy. Rather than advise reality, Howard N. Flaxman of Welsh & Flaxman pocketed Schwemberger's hard-earned for appeal of a hopeless case. In a lot of ways, this is not unusual. But it is a good cautionary tale.

The Invention Zone
6,730,817 claims a process for making a refrigerant gas that won't deplete atmospheric ozone and turn Earth into more of a baking oven than humans are busy otherwise doing. Owner Solvay sued Honeywell for infringing '817. For their pains, Solvay had some asserted claims found infringed, but "invalid under 35 U.S.C. § 102(g)(2) because Honeywell was a prior inventor." Appeal got the invalidity ozone depleted from district court summary judgment.

Spine Solutions, Inc. (SSI) sued Medtronic for infringing 6,936,071, which claims a spinal implant, "used to replace discs between vertebrae in the spinal column that have degenerated or become diseased." 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.

Daiichi Sankyo owns 5,616,599, which claims a compound formula (angiotensin receptor blockers "ARBs") used to treat high blood pressure. Research on this line of drugs began in the 1970s. '599 represents an advancement in the second generation of similar compounds. Mylan's ANDA got the litigation ball rolling. With the pressure on, Mylan couldn't convince the district court, in a 10-day bench trial, that '599 was obvious. The pressure stayed on in appeal.

Eli Lilly got 6,458,811 and 6,894,064 (the "Particle Size Patents") for processing "raloxifene particles until their size falls 'within a specified narrow range.'" Raloxifene, an antiestrogen, aims at treating osteoporosis in women by mimicking estrogen, without inciting increased incidence of breast cancer. 6,906,086; RE39,049; and RE38,968 (the "Bone Loss Patents") aim more specifically at preventing bone loss. 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. Lilly prevailed on all but the Particle Size Patents - not invalidated by prior art, but by failing the written description requirement of §112.

A "bundle breaker" is a machine that separates stacked sheets of corrugated cardboard. 6,655,566 claimed an improvement that allowed a bundle breaker to simultaneously separate stacks of different heights. George M. Martin is this country's king of cardboard stacking. Martin has been stacking cardboard since 1960, and has about 90% of the cardboard stacker machine market. Martin has sold bundle breakers, which incorporate '566's claimed technology, since 2002. Martin sued chief competitor Alliance Machine Systems International for infringement. A hung jury resulted in the judge breaking Martin's potential bundle by ruling the asserted claims obvious. Martin stacked his hopes on the CAFC.

Transocean Offshore Deepwater Drilling innovates so humans can drive around on the cheap until they pollute themselves out of existence. And, as anything that lives in the Gulf of Mexico would tell you (if it could talk), pollution begins at the wellhead. Transocean tried drilling rival Maersk for infringing 6,047,781, 6,068,069, and 6,085,851, in South Texas, where they love oil like cattle love grazing. But apparently not those patents, because the district court held the asserted claims invalid, not infringed, and Maersk not acting willfully. Transocean had to pitch its bit to the CAFC.

King Pharmaceuticals sued Eon Labs for infringing 6,407,128 & 6,683,102 after Eon filed an ANDA to make a generic version of the muscle relaxant claimed, metaxalone, which was first patented in 1962 (3,062,827). Eon got summary judgment of invalidity via six prior art references, three of which the court relied upon. The district court found claims inherently anticipated. "To inherently anticipate, the prior art need only give the same results as the patent, not better." One claim was found inherently obvious. Other claims, in both '128 and '102, were found wanting under §101 for lack of transformation: the claims' "informing" limitation was ethereal. Whereupon appeal, with its own special informing about "informing" being unpatentable. "It is not invention to perceive that the product which others had discovered had qualities they failed to detect."

Wyers sued Master Lock for infringing 6,672,115, 7,165,426, and 7,225,649, applicable to hitch pin locks for trailer towing. A jury found the patents nonobvious. Wyers secured an injunction along with $5.35 million in reasonable royalty damages. Master couldn't break the lock to obviousness post-trial, so it appealed. Herein, a thorough discussion of KSR, and case law that will be cited for years to come.

You don't need to have a novel invention to get a US patent. You just need to beat the clock, a clock rigged to America as superior to inferior foreigners, a patent xenophobia most unbecoming. "Domestic and foreign filing dates stand on entirely different footings." Peter J. Giacomini and his pals tried rigging the clock for their computer data cache patent application. The BPAI upheld the examiner's § 102(e) rejection over 7,039,683 (Tran). Giacomini did not dispute Tran as invalidating if prior art. Giacomini argued Tran was not prior art, even though Tran claimed priority to a provisional application. Giacomini's problem was that Tran's provisional was a US application.

Telcordia sued Cisco for infringing network data transfer patents 4,893,306; 4,835,763; and RE36,633. '306 was knocked out by noninfringement in summary judgment. '763 and '633 ran the gauntlet through trial to a $6.5 million damages award. 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." Telcordia appealed the '306 claim construction. Cisco cross-appealed '306 and '763 validity, as well as the post-trial damages award and ongoing royalty negotiation dictate.

Opium for the Masses
Par Pharmaceutical filed an ANDA to make a time-released version of the opiate tramadol. Patent holder Purdue sued for infringing 6,254,887 & 7,074,430. What was Purdue smoking? The asserted claims were readily obvious in light of 5,580,578. A charge of inequitable conduct by submitting "a materially misleading declaration" was merely "overly aggressive" "positive spin," not intent to deceive.

TriMed sued Stryker in 2006 for infringing 5,931,839, which claims "an implantable device used to set bone fractures." The district court granted summary judgment of noninfringement.

B-K Lighting sued FVC for infringing RE39,084, which claims an adjustable mount for a sealed light fixture. After giving the B-K's expert short shrift, the district court granted summary judgment of invalidity by obviousness for the asserted claims. The per curiam appeal pitched it back to the district court, because of "the conflicting testimony of the parties' experts" about whether a prior art reference disclosed a critical feature. In dissent, Judge Newman put the spotlight on spotty reasoning.

In offering a license, Ablaise accused Dow Jones of infringing 6,961,737 & 6,295,530, claiming web page personalization. Dow Jones replied with a DJ. Realizing that validity was in jeopardy, Ablaise offered a covenant not to sue for '530 (not '737), which Dow Jones spurned, because Ablaise wouldn't extend the covenant to Dows' parent, News Corporation. In the issue of continuing subject matter jurisdiction, the district court waved the proffered covenant away, and kept the railroad running. The district court found the asserted claims obvious in light of Fishwrap, an MIT online newspaper, 5,675,507, a customizable fax viewer, and HTGrep, with optional views of search results. The CAFC took Ablaise's covenant offer more seriously.

Microthin.com sued SiliconeZone computer mouse pad patents 5,942,311 & 5,997,995, which claim "a thin, non-slip mat or pad made of plastic" and a method of making the same, respectively. After claim construction, the district court, by summary judgment, found the asserted claims, claim 1 of each patent, anticipated by 5,738,325. Microthin.com appealed construction of the claim term "non-slip," wanting the term to include "not sticky."

Another patent applicant groans like Tom Jones: "Stop Breaking My Heart." Does this lyric sound familiar? "The applicant argues that these rejections were based on a misunderstanding of the [prior art] references, and lacked sufficient findings by the Board. The applicant states that the Board misinterpreted claims , leading the Board to conclude erroneously that the additional limitations in these claims were taught by [the prior art]. The applicant complains that neither the examiner nor the Board made sufficient findings or adequately explained their reasoning. The PTO, through the Solicitor on this appeal, now seeks to substitute new reasoning for that supplied by the Board concerning how the asserted references should be interpreted." Business as usual at the PTO. But, like Tom Jones hammering home "Sixteen Tons," the CAFC lambasts the PTO for randy rejection.

Jerome sold the patent to Orion in 2004. Orion sued Hyundai and 20 other automakers. The 20 others settled, but Hyundai fought on. Hyundai lost, to the tune of $34 million, plus interest and ongoing 2% royalty. Failing post-judgment JMOL, Hyundai appealed over anticipation and inequitable conduct.

David T. Pelz tried to patent a golf training mat (11/066,554). Non-final rejection purely on anticipation prompted Pelz to amend the preamble.

Hearing Components sued Shure over hearing aid patents 4,880,076; 5,002,151; and 5,401,920, technologies used in Shure's earphones. 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.

Trial found Antec willfully infringing some claims. Some claims were obvious to the jury, others validly novel. Appeal found that "irreconcilably inconsistent." The CAFC resolution was to define analogous art as either "from the same field of endeavor," or "reasonably pertinent to the particular problem with which the inventor is involved." Upon that the CAFC created its own reconcilable inconsistency.

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."

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....

His rejoinder is that it was never public. Lister finally got to the court of appeals.

To characterize USPTO examination quality over the past 20 years as uneven would be a complimentary understatement.

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.

Callaway Golf sued Acushnet over four golf ball patents. Acushnet teed itself up with an admission of infringement, but tried to whack the asserted claims into the sand trap of prior art invalidity.

Douglas J. Shoner had a pneumatic tire design rejected by the PTO over obviousness. Shoner appealed to the CAFC, which affirmed. Shoner's plea (hardly an argument) relied upon reading an unstated limitation into his claim from the spec. "The PTO is required to give claim terms their "broadest reasonable interpretation consistent with the specification," and there is nothing in the specification that would explicitly limit the air chamber to a particular structure... See In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004) ("Absent claim language carrying a narrow meaning, the PTO should only limit the claim based on the specification or prosecution history when those sources expressly disclaim the broader definition.")."

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.

Bryan took it to the CAFC. Apparently, without legal advice.

Martin Gleave and Maxim Signaevsky tried for a patent on an antisense oligodeoxynucleotide, an organic compound. Examiner prior art rejection was upheld by the patent board. On CAFC appeal, two points were made: 1) a reference is anticipatory if enabling, regardless of utility; and 2) knowing a genus anticipates all its species if the genus is so limited that the species hold no mystery.

Clock Spring sued Wrapmaster for infringing 5,632,307. '307 claims a method of gas pipe repair. Without expert affidavits, the district court found in summary judgment the patent invalid due to obviousness, rejecting a prior-use argument. On appeal, the CAFC bought Wrapmaster's showing of prior use: that Clock Spring publically demonstrated the technology in 1989, more than a year prior to filing the patent (1992). Herein, rubber-band §102(b) readily stretches to envelop §103(a). And a discourse on experimental use.

In many instances, the proposed IDS rules will create a prior art search dilemma for patent prosecutors. The new rules require extensive analysis of cited art, reportage that characterizes the claims and thus invites prosecution estoppel, hence hampering enforcement potential, particularly applying the doctrine of equivalents.

Aventis sued Lupin for infringing 5,061,722 after Lupin filed an FDA drug application (ANDA). '722 goes to a blood medication, Altace. District court summary judgment found infringement under the doctrine of equivalents, and a pre-KSR bench trial rendered the patent "not invalid," as the appeals court backhandedly put it. Which is to say, on appeal, the CAFC took the double negative out, finding the patent "would have been obvious." KSR strikes again.

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.

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.

Accessible Prior Art
In Bruckelmyer v. Ground Heaters, the CAFC gives broad latitude to what constitutes "publicly accessible" prior art. The court decided that abandoned drawings of a foreign patent application were "publicly accessible," because the file history could be located from the published patent. The lynchpin seems to be whether the material, or even reference to the material, has been catalogued or indexed, not whether the material itself had ever been published.

Leonard Kahn, trying to patent a reading machine for the blind, appealed his §103 rejection by the patent appeals board (PBAI) to the appeals court. The CAFC (04-1616) in this case further clarified the ground rules for obviousness rejection.

As Monty Python once quipped, no one expects the Spanish Inquisition, but here it is. In a second round of protracted litigation to establish priority of invention, i.e., legal first-to-invent status, Medichem v. Rolabo square off before the CAFC (05-1179, -1248) over the credibility of lab notebooks related to discovering the patented process for making loratadine, the active ingredient in the blockbuster allergy medication Claritin®. This is the second ruling in as many days from the Appeals Court relating to the anachronistic alchemy of having patent priority determination subject to tortuous legal complications at ungodly cost. More simply put, here's another compelling argument for a first-to-file patent priority regime.

The Cure for Junk Patents: Old Hat
The Wall Street Journal yesterday hit the nail on the head: "In Patent Disputes, A Scramble to Prove Ideas Are Old Hat." Silliness aside, and there are a lot of silly patents (see Patently Silly), junk patents most commonly originate because adequate prior art search isn't done during examination. To compound the problem, patent owners trot to court without vetting their wares, potentially costing millions in attorneys fees that can go up in smoke. For professional prior art searchers, finding old hats that kill patents is where the action is.

Veracity Requires Documentation
KSR International v. Teleflex is under consideration for review by the Supreme Court. The issue is the appropriate standard for prior art anticipation vis-à-vis 35 U.S.C 103(a), particularly combination of prior art references. In short, the current standard is that veracity requires documentation. There has been outcry to weaken that standard to allow speculation as a basis for invalidating a patent claim, replacing a reasonable standard of documented certitude with case-by-case subjectivity. What are they thinking?

Secret & Exploited
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".

It's still salad days where patent product prior art posted on the Internet might be useful anticipatory art. The problem is that companies continually update their sites with the latest offerings, shucking antecedents.

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.
