Not Final

Automated Merchandising Sytems (AMS) sued Crane for infringing four patents. Crane responded by filing inter partes reexaminations on the patents. The parties settled. AMS tried to stop the reexams, but the PTO refused. And the courts refused to contravene the PTO refusal.

Not Withdrawn

Prosecutorial nitwittery went unchecked by the district court, but a CAFC panel checked it by siding with the USPTO in refusing to withdraw a terminal disclaimer. 6,194,187 issued. Its owner, the Japanese Foundation for Cancer Research, then filed a terminal disclaimer, which the PTO accepted. The patent office later refused to withdraw the disclaimer, and so was sued for it. Defending the PTO via deference, the CAFC found "that the PTO did not act arbitrarily, act capriciously, or abuse its discretion in declining to use any inherent authority that it might have in withdrawing the terminal disclaimer."

Gaming Appeal

A vexatious corruption haunts the USPTO: examiners that repeatedly pull applications out of appeal with a new rejection. Freda Nelson plagued this inventor for years with her fresh witless rejections after my filing for appeal. In the recent patent board appeal - ex parte Sheklam (2012/009,005) - the offending unnamed examiner is caught out. Other experienced prosecutors report that examiners gaming the system in this way is not especially unusual. PTO management continues to largely turn a blind eye to this practice.

Without Means

An irascible PTO patent board insisted that "a receiver adapted to receiving" invoked the means-plus-function interpretation of §112 ¶6. This in an application for an automatic light switch. The CAFC reversed, finding sufficient structure to understand the bounds of the invention. (Enocean v. Face International CAFC 2012-1645)

An untold number of patent applications languish at the USPTO, which refuses to grant or even examine them, either because they are considered too valuable to be granted to a non-corporate entity, or out of sheer spite. Gilbert P. Hyatt, prolific inventor with over 70 issued patents, can't get the patent office off its duff. So he (once again) went to Federal court "to compel the PTO to decide two appealed patent applications, each of which has been pending before the PTO since the early 1970s - over 40 years ago." The U.S. patent system is broken, but in none of the ways that so-called patent reformers, who represent corporate interests, care to address. Instead, well-heeled efforts focus on rigging the game further against inventors like Mr. Hyatt (e.g., the Goodlatte "abusive litigation" legislation currently making its way through Congress).

The root problem was incompetent prosecution, in drafting claims that neglected to render a single party culpable.

No Benefits

Steve Morsa filed a patent claiming benefits processing. The PTO rejected over prior art, first arguing anticipation; then, when that deficiency was pointed out, hand-waving obviousness. Morsa made cogent, reasonably undeniable arguments, based on evidence, that the prior art used was not in fact prior art - that it was published nearly two years later. Morsa argued that the supposed prior art wasn't enabling, nor a solid basis for obviousness. The PTO didn't care a whit for any of it. The Board granted a rehearing only to pile on new grounds of rejection, without allowing Morsa any opportunity whatsoever to refute the rejections. On appeal, a CAFC panel didn't bother to examine the facts, nor follow the law. Largely ignorning Morsa's arguments, the CAFC rubber-stamped the PTO. The only issue that caught the CAFC's attention was the examiner dismissing Morsa's prior art enablement argument by saying the he had failed to file any expert declartion or affidavit in support. That odious requirement went too far. "We see no reason to require such submissions in all cases," the CAFC panel opined. "Here, Morsa identified specific, concrete reasons why he believed the short press release at issue was not enabling, and the Board and the examiner failed to address these arguments." For this a partial remand, though to moot point - only to clean a smudge on the claims' death warrant. The claims were damned over an unsupported conjecture of obviousness. One more chip on the pile exposing the fundamentally lawless process of caprice by the U.S. patent office and at the CAFC. (CAFC 2012-1609)

Ignoring the Preamble

Eric Jasinski tried to get a patent for testing computer memory via "verifying the accuracy of logical-to-physical mapping software designed for testing memory devices." In finding anticipation, the USPTO Board ignored the preamble limitation, which was also called out in the body of the claim. In a rare reversal by the CAFC (2012-1482) of patent office rejection, a panel rightly observed: "it also provides the criteria by which the previously-recited comparing limitation is analyzed. We thus conclude that the 'to verify/verifying' language is limiting." If there's a practical lesson here (aside from the capricious irrascibility of the PTO), it's to not rely on the preamble as limiting.

Out of Whack

The USPTO's curmudgeonly incompetence was on display at the CAFC last week. Abbott Diabetes Care had its patents put under reexamination by a third party. The PTO denied the patent it had once granted; a failure of initial examination. In the reexam, the construction of "electrochemical sensor" was disputed. The CAFC found that "the Board's construction of 'electrochemical sensor' is unreasonable and inconsistent with the language of the claims and the specification." The patent appeals board also reversed itself before the CAFC on having agreed with the examiner on rejecting new claims based upon "official notice," which is shorthand for "no evidence."

In re Baxter (CAFC 2011-1073), a majority allow the USPTO to overturn in reexamination a decision of law made by the court. Only Judge Newman is perturbed. "The Patent and Trademark Office's Board of Patent Appeals and Interferences, on reexamination of a patent that had previously been litigated to final judgment in the district court and on appeal to the Federal Circuit, states that "the agency is not bound by the court's determination." My colleagues appear unperturbed by the agency's nullification of this court's final decision. Instead, the court itself ignores our own prior final decision, although it is the law of this case. Thus the court violates not only the constitutional plan, but also violates the rules of litigation repose as well as the rules of estoppel and preclusion - for the issue of validity, the evidence, and the parties in interest are the same in this agency reexamination as in the finally resolved litigation."

A patent disclosure often describes the drawings, which are required "where necessary for the understanding of the subject matter sought to be patented." 35 U.S.C. 113. Kevin Price celebrates the art form in The Art of the Patent. The book is a nicely done picture book, and well thought out, though slight. The text is juvenille, written for junior high school level, both in content and gee-whiz attitude. The opportunity to explain the craft of patent illustration is foregone. This would have been a much better book with more maturity, and truer appreciation of skill by exposition, rather than mere illustration. That might have made the book a reference worth returning to, rather than something consumed in a sitting or two, and then left on the shelf. That said, it is the perfect book for the lobby coffee table of a patent prosecution firm. Perhaps that was the target audience all along.

Best practice for patents that have not had all potential value squeezed is to file continuations and divisionals. Keep the patent alive to mine untapped potential. The only remedy to modify extant claims is reissue. For two years from issuance, claim scope may be enlarged. After that, reissue claims may only be narrowed. This is typically done as a hedge against invalidity. Yasuhito Tanaka sought to do just that, after failing to do more. The sledding was much tougher than it should have been.

Thanks in large part to KSR, it has become harder to obtain a patent grant in recent years. It is one thing when an Examiner makes a ruling based on sound logic and reasoning to reject an applicant's claims; that is their burden and their duty.  But it is quite another when a rejection is based on nothing more than a poor misapplication of the law, under the pretense of the MPEP.

The noxiousness of the faux first-to-invent regime that the U.S. alone clings to is seldom exposed to the harsh daylight of the appeals court. Philips got its pulse up over a patent it inherited when it drew the short straw in a BPAI interference against Cardiac Science. Philips sued in Washington district court, where the judge sua sponte ditched the case with prejudice, provoking appeal. The CAFC reminded of the intricate rules that the PTO ignored, and the district court failed to heed.

RFID Tracker sued Wal-Mart and others for infringing 6,967,563, claiming an RFID reader. The district court judge construed the claim to exclude the RFID reader from also being a transmitter, owing to prosecution disclaimer. Hence, the defendants could not be tagged for infringement, because their reader included a transmitter. RFID Tracker trekked to appeal.

More than ever, patent prosecution is a gambler's game. As Admiral Adama in Battlestar Galactica observes: "sometimes you have to roll the hard six." In prosecution, facing an objectionable rejection, appeal. Professor Dennis D. Crouch has taken a cold-eyed look at rejection rates for BPAI appeals. Not a savory prospect. The hard six is a very hard roll, particularly when playing against Obzilla.

AE = Accelerated Excuses

Start with a well-designed, seemingly effective program; add bureaucratic tanglese; top it off with the ubiquitous "we are always right, as we are the government" mentality, and, what do you get? The USPTO Accelerated Examination (AE) program in actuality. In a non-surprising move, the USPTO has rejected numerous otherwise valid requests for AE on the slightest technicalities. Apparently the easiest way to meet the goal of disposal within one year is to dispose of many without examination, and with no regard to fairness.

Louis Stumberg and James Fulton invented a safety device for firefighters: automatically sounding an alarm if a firefighter didn't move for some time (presumably incapacitated). In 1989, the inventors hired Akin Gump to file a series of patents. Upon later enforcing the patents, they wound up getting settlements totaling $9 million. John Raley of Cooper & Scully, one of the firms representing the inventors: "When these actions were settled, they were settled much more cheaply than they should have been settled for. The royalty that should have been awarded to these plaintiffs was far less than if Akin Gump had done their job properly in handling the patent applications." The apparent problem: the prosecutor had failed to disclose information material to the patent, and, according to Raley, did so with intent to deceive the PTO.

Doubled Over

Dr. Frits Jacobus Fallaux stumbled into a continuation dilemma. The fifth in a family series ran into a double patenting rejection. Earlier patents in the family only one shared inventor in the family, and the earlier patents were owned by a different assignee at the time of rejection. The examiner applied the normal one-way test for obviousness-type, i.e., non-statutory double patenting on some claims. Unable to file a terminal disclaimer to eliminate the issue, because of the earlier patents being assigned away, Fallaux countered that the more rarely applied two-way test was appropriate.

Double Patenting Dilemma

Takeda Pharmaceutical filed a patent application for cephem antibiotic compounds, and the process for making those compounds, in Japan, in December 1974. Takeda in 1975 filed corresponding applications in the UK and US. The US family started with 4,098,888 & 4,298,606. In 1990, Takeda filed for what became  5,583,216, which covered a process for making the compounds claimed in '888 and '606. Anonymous requests for reexamination of '216 led to a double patenting dilemma, which the appeals court resolved badly, not thinking through the implications of its ruling.

The validity of a granted patent may be challenged before the USPTO at any time during a patent's life. There are two types of reexamination: ex parte and inter partes. Both start by petition to the Office, with the petitioner citing "a substantial new question" of patentability in the form of prior art. The older ex parte form comprises a one-shot injection of prior art. Inter partes reexamination, introduced in 1999, affords the petitioner continued kibitzing. At a cost.

Intellectually Amish

Patent examiners are embracing §101 rejection for process claims, reinvigorated by Bilski. Oddly, the rejections often skirt citing Bilski directly, instead relying upon earlier precedent, such as Benson. The Bilski ruling favorably cited 1982 Abele for discrimination between overreaching claims and more "narrowly-claimed process patent-eligible." Abele provides an escape route from rejection, by analogy: data that represents "physical and tangible objects."

The claims lack the necessary physical articles or objects to constitute a machine or a manufacture within the meaning of 35 USC 101.They are clearly not a series of steps or acts to be a process nor are they a combination of chemical compounds to be a composition of matter.

As Wall Street floats on an ocean of dumb money, so invention floats on an ocean of dumb patents. Frequently, patent holders solicit Patent Hawk services with "lame duck" patents - a solitaire patent, often with weak claims, without any continuation. Are prosecution firms, many well-known nameplates, so inept as to not advise their clients to grow a portfolio, so as to improve claim scope coverage? So inept to not have a clue as to how patents are enforced, even as many of those firms work both prosecution and litigation? Repeated anecdotal evidence over the years answers a bit too emphatically "yes."

Old Art Never Dies

A common patent litigation strategy has been to seek reexamination after losing in court, as in the case herein. Defendant counsel has more rhetorical power before the court, as contrasted to a single injection to the PTO for reexam, after which the patentee tries to hold granted ground while an infringer watches from the sidelines. And a post-verdict reexam is as much for spite as anything, as it doesn't necessarily turn back the clock.

Today's CAFC ruling should flip the litigation-first/reexam-last-ditch strategy on its head: scorching prior art search to reexam first, pleading a stay of litigation pending reexam outcome. That's because court validation is not subject to reconsideration from PTO invalidation, but a PTO kill terminally damns. Further, previously cited art can be rehashed in reexam.

Laying yet another brick of fortification against junk patents, the CAFC clarifies the power of reexamination as a "quality check."

Patent Agent Alex Nix recently created Patent Bar Questions, a Wiki, inspired by a thread at Intellectual Property Forums, geared toward poor souls preparing for that test that separates the savvy from the savant. The relatively simple site is bifurcated: Key Things to Know for the Patent Bar Exam, a chapter by chapter walkthrough of the MPEP that highlights key sections; and Questions reportedly asked in the Patent Bar Exam, a listing of questions reported by those who have recently taken the exam. Since reported strictly from memory, the questions are not comprehensive, instead reading more like concept areas. The Wiki is currently a wee sparse; hence, better treated as a supplemental source of information, rather than a primary. For those wanting in-depth Patent Bar study materials, one of the many commercial-test-prep companies is still the way to go.

Round one vacated the BPAI decision for failing to specify a motivation for a combination obviousness finding. Motivation became passé as KSR sucked the oxygen out of the CAFC's longstanding teaching-suggestion-motivation (TSM) test.

The Perils of Prosecution

With proclivity to despotic rule-making, USPTO management has issued edict to trash examination to the lowest common denominator. Playing the numbers to demonstrate its toughness, top management determination was to sink the allowance rate. Many moons ago, anticipating outcry at examination injustice, the agency geared up for a ramp in appeals. Outrageous incompetence is in full flower at the PTO. The governmental agency representing the sanctity of invention has been so corrupted as to soil itself in disgrace; in doing so, pointing out the woeful neglect of its overseers.

USPTO management is pushing rule-crack on examiners, who are smoking it. Rule-crack: crystallized infractions homeopathically processed so that they don't even exist in CFR form. Before rampant rule-crack ingestion, the majority of examiners were randomly competent at best. Engendering curmudgeonly denial of due process, rule-crack is spawning egregious intellectual property theft.

Citing Prior Art

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. In a field crowded with art, to minimize cost while maximizing patentability under the new IDS rules, a crafty prior art strategy is imperative.

The Hanging Tree

Patent malpractice accusations are becoming more frequent as the value of patents has generally increased. With that, the costs associated with malpractice are also going up. Back in 1985, IP attorneys were but a shade over one-half percent of malpractice claims. The rate as of 1999 had breached the 1% mark. With USPTO prosecution proceedings becoming positively squirrelly, and thus more demanding upon prosecutors, a specter looms that the patent malpractice problem may worsen.

Thanks to KSR, the bar of §103(a) is set obscenely high for patent prosecution. Examiner rejections on obviousness, regularly combining three and four references to cover all the claim limitations, reek of hindsight, and are pasted with the thinnest of glue: e.g. "it would have been obvious to one of ordinary skill in the art at the time of invention to combine four patentably distinct references of unrelated subject matter because it would have been advantageous, as the applicant claimed."

Markush claims recite groups of workable alternatives. As such, relative to other claim types, Markush claims are intrinsically complex. Markush claims easily mushroom into a plethora of possible permutations. Hence, Markush claims present a considerable examination challenge: namely, searching prior art for the possible alternatives.

Merck claims the extension rides on the tail of the terminal disclaimer, extending the patent to the end of 2007. Hi-Tech Pharmaceutical wants to market a generic version, and says there is no tail to a terminal disclaimer, at least in this instance.

The USPTO has released the 8th edition, Revision 5 of its Manual of Patent Examining Procedure (MPEP), the patent bible. But 8r5 is released in pdf format only; no hyperlinked web (html) version.

Dependent Claim Koan

What is the value of a dependent claim whose limitations are anticipated by the prior art? Considering the current obviousness standard, most recently enunciated in Alza v. Mylan, is there good reason to assert, or even draft, such dependent claims? After all, if the independent claim is done in by prior art during litigation, the dependent claim practically falls as well. Comments welcome.

Fast Track Patenting

On Monday, the USPTO announced an "accelerated examination" program to go from application to grant (or denial) within one year, appeal notwithstanding. The catches are that the applicant bears the examination burden of searching & explaining the prior art, and elucidating enablement & definiteness, as well as limiting the claims under examination.

Patent Prosecution Highway

Aiming at an international pendency problem, the U.S. and Japan's patent agencies are joining in a patent prosecution cluster farce, together building a so-called Patent Prosecution Highway, hoping applicants filing for patents in both Japan and the U.S. will jump through hoops to get granted claims on either side of the puddle fast-tracked on the other side, whatever that amounts to.

In what promises to be another public flogging, the patent office is going to reexamine Forgent Network's JPEG patent (4,698,672), which has less than a year of life left in it, and has yielded over a $105 million in licenses from over 40 companies, with another 44 currently on the docket for infringement, all of whom have had a chance to douse the patent with invalidity assertion before the courts. Officious PubPat, which specializes in rubbing patents' noses in reexam, instigated, and the patent office, feeling the need nowadays to be ever so politically correct, bit.

Many inventors are disappointed to learn that their idea by itself cannot be patented. Typically, their idea could be patented if it were developed a bit further. This “I-got-a-great-idea” stage isn’t enough because U.S. patent law requires that the invention be both “conceived” and “reduced to practice.”

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.
