Patent Claims Continue to Drop

Patent, Patent Applications

PatentlyO077

The chart above shows the percentage of patent applications published with more than twenty claims, grouped by publication date. I use the twenty-claim threshold because patent applicants are required to pay a surcharge to the USPTO for each claim over that limit.

As the chart shows, the percentage of applications with more than twenty claims has been declining for much of the past decade. This change is even more dramatic when looking at applications with forty or more claims.

PatentlyO078

Of course, if the percentage of high-claim applications is decreasing, the percentage of mid– or low-claim applications must show some increases.  The chart below presents a time series showing the percentage of patent applications with fifteen-to-twenty claims.

Facilitating Freedom-to-Operate Searches

Patent, Patent Applications

by Dennis Crouch

A good freedom-to-operate (FTO) search will include a search of pending patent applications with an eye toward potential future threats. Over the past decade, the USPTO has published over 2.5 million patent applications. One problem with using that database for freedom-to-operate searches is that most of the published applications are either (1) already patented or (2) abandoned. Over the past three months (June –  August 2010), for instance, about 80,000 published applications were “disposed of.” If we include unpublished applications, during that period, 36,862 US utility patent applications were abandoned and 62,686 utility patents were issued.

Patent academics argue about the vague nature of pending applications (largely because claims can be modified prior to issuance). However, up to now, the database of published applications has been difficult to use as a FTO search database for a far simpler reason — most of the results in a patent application search are for applications that are no longer pending.  Those concluded cases unnecessarily clog the results.

As far as I know, no search-software-vendor has taken on the task of offering US patent application search results that include only pending applications.  Part of the difficulty of accomplishing that result is that it has been difficult to identify which applications have been abandoned.  

As part of its data transparency project, the USPTO recently began publishing a list of abandoned patent applications. [LINK]. In the near future, I expect that this newly available data will be helping to facilitate your FTO searches.

Prometheus v. Mayo: Patenting Medical Methods

Method Claims, Patent, Patent Cases 2010, Patentable Subject Matter

Prometheus Labs. v. Mayo Collaborative Services (Mayo Clinic) (Fed. Cir. 2010)

This case is one of several pending Federal Circuit appeals that are questioning whether medical diagnostic and treatment methods are the proper subject of patent protection.

The claims asserted by Prometheus are directed toward a method of “optimizing therapeutic efficacy” by first administering an active drug (6-thioguanine) to a subject and then using the subject’s metabolite blood-level to adjust future doses of the drug.  (U.S. Patents 6,355,623 and 6,680,302). Thus, most of the claims are centered around three ordered-steps of:

  1. administering the drug to the subject;
  2. determining the amount of drug in the subject’s blood; and
  3. re-calibrating the drug dosage based on step-2.

A broader claim (claim 46 of the ‘632 patent) eliminates the administering step of claim 1 above.

The district court found the claims invalid as lacking patentable subject matter under 35 U.S.C. 101.  On appeal, the Federal Circuit reversed — holding that the steps of “administering a drug” and “determining the level of 6-thioguanine” were both sufficiently transformative of “a particular article into a different state or thing.”  That Federal Circut decision was based on the court’s machine-or-transformation test that was subsequently discredited by the Supreme Court in Bilski v. Kappos (2010).  In the wake of its Bilski decision, the Supreme Court vacated the Federal Circuit’s Prometheus decision and remanded for a new opinion.  Seeing this as a potential watershed case, Mayo immediately requested that the Federal Circuit hear the case en banc.

Briefing by October 1: The Federal Circuit has apparently denied the en banc request and has moved-forward with a rapid briefing schedule: By October 1, 2010, both parties are scheduled to submit 20–page briefs “addressing the effect of the Supreme Court’s Bilski decision on the disposition of this case. No additional briefing or oral argument is contemplated at this time.”  The scheduling order was signed by the court clerk Jan Horbaly.

Judges in Charge: The scheduling order suggests that the remand will be taken as a supplement to the original decision. A quirk of that original decision is that the three-member panel included two judges who are not on the Federal Circuit (Chief Judge Paul Michel (Ret.) and E.D. Texas District Court Judge Ron Clark). The third member of the panel is Judge Lourie.  Federal Circuit rules indicate that Judge Clark can retain on the panel on remand, but would not be part of any en banc hearing.

Related cases include Classen Immunotherapies Inc. v. Biogen Idec (method of determining an immunization schedule) and Association for Molecular Pathology v. Myriad Genetics (gene patents). 

Successor Company Holds Patents Assigned to Predecessor Company (Even if Assigned after Predecessor Dissolved)

Infringement, Ownership, Patent, Patent Cases 2010

Tri-Star Electronics Int'l. v. Preci-Dip Durtal SA (Fed. Cir. 2010)

Mr. Kerek (from Ohio) invented the claimed “socket contact” while an employee of Tri-Star and he duly executed an assignment of his rights to to Tri-Star.  The year prior to the invention, Tri-Star (OHIO) had merged and become Tri-Star (CALIFORNIA).  However, Kerek's assignment clearly stated that the assignment of rights was to Tri-Star (OHIO) — even though that Ohio company no longer existed. Later, Tri-Star (CALIFORNIA) merged and became Tri-Star (DELAWARE).

Here, the accused infringer has challenged whether Tri-Star (DELAWARE) has standing as owner of the patent rights.  The Federal Circuit accepted this interlocutory appeal and held that Tri-Star (DELAWARE) is the owner of the patent rights.  

In making its decision, the Federal Circuit found two points of law important:

First, contract law attempts to satisfy the mutual intent of the parties, and here, it was clear that the employee had intended to transfer rights to his employer as required by the employment contract.

Second, even after a merger, a predecessor company continues to exist under Ohio law for the purposes of allowing its property to vest.

Based on these two points, the Federal Circuit held that the stated transfer to the merged Tri-Star (OHIO) equated to a transfer to its successor Tri-Star (CALIFORNIA). The later transfer to Tri-Star (DELAWARE) was not disputed.

* * * * *

I have no problem with the Federal Circuit's statements regarding Ohio law — it is correct as far as I know. However, I do have some concern with the ongoing fallacy that there is no Federal law or policy controlling the transfer of patent rights. On point, there is a Federal Law requiring that patent assignments be done “in writing.” 35 U.S.C. 261. Based on that statute, the court should have considered how the supposed transfer from Kerek to Tri-Star (CALIFORNIA) fits within that statutory requirement. In addition, we have seen an increasing number of companies playing games with the patent recordation system by using shell corporations and by mis-recording assignment records. Here, for instance, the assignment record showed ownership by Tri-Star (CALIFORNIA) despite the documentation in the underlying assignment.  Those concerns are important — especially if we believe that the public properly has an interest in knowing the identity of patent owners.

IN DEFENSE OF SOFTWARE PATENTS – PART 2

Articles and Publications, Patent, Patentable Subject Matter, Software, ,

Guest Post by Martin Goetz

 

Back on November 30, 2009, Patently-O published my article “In Defense of Software Patents” in response to the editorial “Abandoning Software Patents” by Ciaran O’Riordan, Director of End Software Patents (posted on Patently-O on November 6, 2009) which had as its premise that software companies are trying to protect “software ideas”.

 

In this article I comment on the Bilski Opinion as well as give some concrete examples of software-only patents as well as hardware/software patents. Also, my previous article received hundreds of comments, many being negative, and part of this new post is in response to those negative comments.

 

Since the June 28th Supreme Court Bilski decision there have been many articles[1] on what the Opinion stated and inferred about the patentability of software.

 

The Opinion restated what previous Supreme Courts concluded: that laws of nature, physical phenomena, mathematics, mathematical formulas (by themselves), algorithms (by themselves), and abstract ideas (which would include software ideas) are not eligible for patent protection.

 

While the Bilski Opinion never directly questioned the patentability of software, the Justices wrote extensively about the meaning of Section 101, the meaning of the term “process” and why the test for patent eligibility should not exclusively be “the machine-or –transformation test”. Justice Kennedy, with the concurrence of all other Supreme Court members, wrote that the Information Age puts innovation in the hands of more people and raises new difficulties for the patent law (and the Patent Office) to determine who should or should not receive patent protection.[2]

 

My November 2009 Patently-O article “In Defense of Software Patents” produced hundreds of comments. Many wrote that they were against the patenting of software because software was an “algorithm” or “mathematics”. In that article my primary argument was that a computer software invention is as patentable as a computer hardware invention and the only difference is the mode of implementation. My thesis was that Software Product companies in the Software Industry are looking to patent a machine process and not a computer program, which is protected by the copyright law. I showed why software product companies can be viewed as high technology manufacturing entities and should be just as eligible for patent protection as computer hardware companies.   

 

In this article I give examples of patents where the preferred implementation of an inventive machine process is in software (via a computer program[3]), hardware (via circuitry), or a combination of both software and hardware.

 

There is little argument that “processes” and “machine processes” are patentable subject matter[4] The question has always been about the nature of software and what one is trying to patent. For over 40 years I have been involved in that argument since I received the first software patent in 1968 for an innovative way to sort large amounts data on a computer that had tape drives that could only read and write data in a forward direction (See Patent # 3,380,029, Sorting System, Issued April 23, 1968).

 

The Sorting System patent was dubbed a software patent but it could also have been a computer hardware patent. It was dubbed a software patent solely because the preferred implementation (the disclosure) was a logic chart (which is recognized by the patent office as a proper disclosure). My Sorting System patent would not have been controversial if the disclosure had been hardware circuitry since there were many hardware patents for sorting data on special-purpose computers and special apparatus. In my patent application I referenced six of those patents which all had unique hardware circuitry in their patent disclosure. Three of them are available online, courtesy of Google Patent Search[5].

 

From 1968 through 1980 my previous company, Applied Data Research filed Amicus briefs in the Prater & Wei, Benson, Johnson, Flook, and Diehr cases in which we argued that a machine process patentable in hardware is equally patentable in software. Here is exactly how we posed a “Question of Law” “in our 1980 Diehr brief:

Whether a computerized machine or industrial process that is patentable subject matter under 35 USC 101 when constructed with a hardware program (wired circuits) would also be patentable subject matter when constructed with a stored computer program (i.e., firmware or software)?

The USPTO is currently in agreement with that “Question of Law” when in 1996 it published its Examination Guidelines for Computer-Related Inventions (Final Version).  The Guidelines stated in its Introduction the following: “The Guidelines alter the procedure office personnel will follow when examining applications drawn to computer-related inventions and are equally applicable to claimed inventions implemented in hardware or software.”

 

In that 1980 Diehr brief we also posed the following argument to the Supreme Court:

An inventor demonstrates his new invention to his patent attorney with great pride; he has developed a cabinet for reading books out loud to the blind. The cabinet contains both a reading and talking computer. After the demonstration, the patent attorney responds:

 

What's inside the cabinet? Did you build it with software or hardware (a stored program or hardware circuitry)? If built with a hardware program, your machine would be patentable. But if you built it with a stored program, the Patent Office would say it was merely mathematics and, therefore, unpatentable.”

The example above of a hypothetical “cabinet for the blind” invention was back in 1980 in our Diehr Amicus brief.

 

Twenty years later, in 2000, a renowned inventor, Ray Kurzweil received a patent named Reading System which Reads Aloud From An Image Representation Of A Document. The patent disclosure shows a diagram of a monitor, scanner, speakers, and a PC computer composed of a processor, storage and a keyboard. The essence of the disclosure and the invention is a logic chart describing a machine system which interacts with a speech synchronizer and the various devices.  

 

The first sentence of the abstract in the patent stated “a reading system includes a computer and a mass storage device including software comprising instructions for causing a computer to accept an image file generated from optically scanning an image of a document.”

 

At that time, Ray Kurzweil’s company, Kurzweil Educational Systems marketed a special purpose hardware/software system called the Kurzweil 3000 Reading Machine which was marketed to the blind and poor readers. Their 2000 year patent protected this product from imitators. Today the company sells a software only system called Kurzweil 3000 and continues to have the protection of the patent system thru his original 2000 patent and with additional patents e.g., Reducing processing latency in optical character recognition for portable reading machine (which is a software-only patent).

 

Few would argue that the Kurzweil 3000 Reading Machine was not an invention and not deserving of a patent.

 

While I am a strong advocate for software-related patents I have always been opposed to the patenting of Business Method Patents (BMPs). In my 2006 article Patents: Where's the Invention? I stated that the Patent Office should do what the European Patent Convention did when it  ruled that anything that consists of "schemes, rules and methods for performing mental acts, playing games or doing business, and programs for computers" is not an invention and therefore not patentable.” Justice Stevens, in his Opinion[6] also wanted to ban BMP’s from being patentable subject matter when he concluded that a method of doing business is not a “process” under 101.

 

Although the Bilski Opinion disallowed the Bilski application they stated that under certain conditions business methods could still be patentable subject matter. On July 27th the USPTO set up more stringent rules for the issuance of BMPs in their Interim Guidance for Determining Subject Matter Eligibility for Process Claims in View of Bilski v. Kappos. In many ways those guidelines are similar to the way computer software and hardware patents are currently being treated under the 1996 Guidelines for Computer-Related Inventions.    

 

One of the greatest challenges facing the Patent office today for BMPs, software or hardware patent applications is in discovering prior art and determining if there is an invention. The USPTO “Peer to Patent” pilot project” which  allows the public (including professionals in their respective fields) to comment on patent applications is still in its infancy, but offers the potential to assist the Patent Office in rejecting the large number of applications that are filed each year. The stated goal of the pilot project was to “connect the USPTO to an open network of experts online.”   Also, private companies e.g., the Article One Partners, a patent research firm, have the potential to significantly reduce the large number of patent litigation cases.

 

In conclusion, while I am a strong proponent of software patents I am very aware, and agree with, many of the arguments against patents because of patent trolls, frivolous patents, e.g. Amazon’s one-click patent, and frivolous patent litigation that can put companies out of business. And I support changes in the Patent Law to reduce those problems. But if one believes in the how the Patent System has fostered innovation and helped the US grow and prosper, then there is no rational reason to eliminate technology inventions that use software as its implementation.

 

In my previous article there were many comments from die-hards that continued to believe that software companies are trying to patent a computer program,  Whether those die-hards still  believe that a computer program is mathematics, or a mathematical formula, or an algorithm, or an abstract idea, so be it. Computer software programs are not what software companies are trying to patent. A software patent invention is on a unique machine process —- nothing more and nothing less. And the criteria should be 1. Innovation 2. A proper disclosure and 3. Usefulness — the same requirement that is the criteria for all patentable subject matter.

[1] Click below for a sample of many of these articles. Reading the Bilski Tea Leaves For What The Supreme Court Thinks Of Software Patents Comments on Bilski and Software Patents; Here's Bilski: It's Affirmed, But . . .No Decision on Software Patentability; Supreme Court Decision Raises Software Patent Questions; Supreme Court 'Bilski' ruling doesn't rule out software, business-method patents; Software patent debate rages on; Software, pharmaceutical, and business method patents survive; Patent Office Says No to Supreme Court and Software Patents; Death Knell For Software Patents; Software Is Not Necessarily Business Method; Software Patents and Business Method Patents Still Possible after Bilski Supreme Court Decision.

 

[2](Underlining and bold added) (pages 9 & 10) “The machine-or-transformation test may well provide a sufficient basis for evaluating processes similar to those in the Industrial Age—for example, inventions grounded in a physical or other tangible form. But there are reasons to doubt whether the test should be the sole criterion for determining the patentability of inventions in the Information Age. As numerous amicus briefs argue, the machine-or-transformation test would create uncertainty as to the patentability of software, advanced diagnostic medicine techniques, and inventions based on linear programming, data compression, and the manipulation of digital signals. See, e.g., Brief for Business Software Alliance 24– 25; Brief for Biotechnology Industry Organization et al. 14–27; Brief for Boston Patent Law Association 8–15; Brief for Houston Intellectual Property Law Association 17–22; Brief for Dolby Labs., Inc., et al.”

 

The Opinion went on to state:

It is important to emphasize that the Court today is not commenting on the patentability of any particular invention, let alone holding that any of the above-mentioned technologies from the Information Age should or should not receive patent protection. This Age puts the possibility of innovation in the hands of more people and raises new difficulties for the patent law. With ever more people trying to innovate and thus seeking patent protections for their inventions, the patent law faces a great challenge in striking the balance between protecting inventors and not granting monopolies over procedures that others would discover by independent, creative application of general principles. Nothing in this opinion should be read to take a position on where that balance ought to be struck.

[3] While the implementation is in a computer program, the disclosure for one skilled in the art, are thru flow charts (also called logic charts) and thru block diagrams.

[4]. The Bilski Opinion closely examined the meaning and the words of 35 U.S.C 101. From 35 U.S.C. 101: Inventions patentable: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent there for, subject to the conditions and requirements of this title.

[5] The Sorting Patents below were described thru and/or gates, and as methods and apparatus for sorting data. Sorting Device, Fillebrown, 5/1961 #2,985,864; Sorting Apparatus, Guerber, 5/1960 #2,935,732; Apparatus for sorting of Recorded Digital data, Dirks 3/1966 #3,242,466.

 

[6] (page 15) Because the text of §101 does not on its face convey the scope of patentable processes, it is necessary, in my view, to review the history of our patent law in some detail. This approach yields a much more straightforward answer to this case than the Court’s. As I read the history, it strongly supports the conclusion that a method of doing business is not a “process” under §101.

 

Preambles as Limitations

Claim Construction, Patent, Patent Cases 2010,

By Jason Rantanen

American Medical Systems, Inc. v. Biolitec, Inc. (Fed. Cir. 2010)
Panel: Bryson (author), Dyk (dissenting), and Prost

It may come as no surprise that the law on whether claim preambles can serve as limitations is unclear.  The Federal Circuit is aware of this issue, and at least one judge suggests that it may be time for the court to address this issue en banc.

The patent in this case, No. 6,986,764, relates to technology for vaporizing tissue using laser radiation.  The invention can be used to treat Benign Prostatic Hyperplasia, a condition in which growth of the prostate gland restricts the passage of urine out of the bladder and through the urethra.  By vaporizing or ablating some tissue, the size of the prostate is reduced, thus reducing bladder outlet obstructions.  Although laser radiation was known in the art, various problems were associated with its use.

The inventors of the '764 patent determined that by using high "volumetric power density" (a high amount of energy delivered to a given volume of tissue) they could produce increased vaporization efficiency while minimizing one of the problems associated with the procedure, residual coagulation.  The patent is directed to various methods and devices for achieving this high volumetric power density by manipulating variables such as wavelength, output power, beam quality, irrigant composition, and distance between the optical fiber and the tissue.

The dispute on appeal hinged on whether the preamble constituted a limitation.  Claim 31 is representative of the method claims. (The apparatus claims are similar, but recite "[a]n apparatus for photoselective vaporization of tissue.")  It recites:

A method for photoselective vaporization of tissue, comprising:

delivering laser radiation to a treatment area on the tissue, the laser radiation having a wavelength and having irradiance in the treatment area sufficient to cause vaporization of a substantially greater volume of tissue than a volume of residual coagulated tissue caused by the laser radiation, wherein the delivered laser radiation has an average irradiance in the treatment area greater than 10 kiloWatts/cm2 in a spot size at least 0.05 mm2.

During claim construction, the district court determined that the preamble phrase "photoselective vaporization" was a "fundamental characteristic" of the invention, and construed the term to mean "using a wavelength that is highly absorptive in the tissue, while being absorbed only to a negligible degree by water or other irrigant."  Based on this construction, the court granted summary judgment in favor of the accused infringer.

On appeal, the majority disagreed, concluding that the preamble phrase "photoselective vaporization of tissue" does not limit the claims of the '764 patent.  The court first noted the limited circumstances in which the preamble may limit claim scope:

“Generally,” we have said, “the preamble does not limit the claims.”  Nonetheless, the preamble may be construed as limiting “if it recites essential structure or steps, or if it is ‘necessary to give life, meaning, and vitality’ to the claim.” A preamble is not regarded as limiting, however, “when the claim body describes a structurally complete invention such that deletion of the preamble phrase does not affect the structure or steps of the claimed invention.”  If the preamble “is reasonably susceptible to being construed to be merely duplicative of the limitations in the body of the claim (and was not clearly added to overcome a [prior art] rejection), we do not construe it to be a separate limitation.”  We have held that the preamble has no separate limiting effect if, for example, “the preamble merely gives a descriptive name to the set of limitations in the body of the claim that completely set forth the invention.”

Slip Op. at 8-9 (internal citations omitted).  After rejecting a prosecution history-based argument and the argument that the preamble phrase provided a necessary antecedent basis, the court determined that the phrase "does not embody an essential component of the invention":

Instead, the term “photoselective vaporization” is simply a descriptive name for the invention that is fully set forth in the bodies of the claims….The bodies of the asserted apparatus claims (claims 63-64) describe a structurally complete device, including a laser adapted to deliver “radiation at a wavelength and irradiance . . . sufficient to cause [tissue] vaporization[.]” The bodies of those claims identify the covered wavelengths by function (“sufficient to cause vaporization”), and nothing in the claim language suggests that the term “photoselective” further limits those wavelengths.

Slip Op. at 10 (internal citations omitted).

Judge Dyk disagreed.  After first noting the confusing and unclear nature of the court's jurisprudence on this issue, he suggested that the court should dispense with the current articulation and instead apply the rule that preambles always limit claims:

It seems to me that a rule recognizing that all preambles are limiting would make better sense and would better serve the interests of all concerned. There is, after all, little to be said in favor of allowing an applicant, in the claim drafting process, to include material in the claims that is not binding. If patentees are allowed to include material in the claim definitions that is not bind-ing, patentees can suggest or imply one position before the U.S. Patent & Trademark Office (“PTO”) to secure allowance of the patent on the theory that the preamble is limiting and another, inconsistent position in infringe-ment litigation on the theory that it is not limiting. Principles of fairness thus dictate that the patentee should be required to clearly define the claimed inven-tion’s scope. By creating a uniform rule that all pream-bles are limiting, we would ensure the patentee has the burden of drafting a patent that avoids confusion as to the scope of the claims….Neither the Supreme Court nor our court sitting en banc has ever addressed the preamble limitation issue. I think the time may have come for us to eliminate this vague and confusing rule.

Dissent at 3-4.  He then turned to the issue of whether the preamble phrase in this case limited the scope of the patent, and concluded that it did based on the prosecution history and what he viewed as a definition of the term in the Summary of the Invention.  He also disagreed with the majority that the district court's construction would be inconsistent with the specification. 

GPG v. ITC: Federal Circuit Review of ITC Determinations

Infringement, Patent, Patent Cases 2010,

By Jason Rantanen

General Protecht Group v. International Trade Commission (Fed. Cir. 2010)
Majority opinion authored by Judge Dyk, joined by Judge Prost.  Dissenting opinion by Judge Newman.

ITC determinations are subject to review by the Federal Circuit under the standards of the Administrative Procedure Act, which allows for de novo review of legal determinations and review of factual findings for substantial evidence.  Although the parties in this appeal largely agreed on the meanings of the relevant claim terms, the majority concluded that the ITC's infringement finding lacked substantial evidence.  Writing in dissent, Judge Newman asserted that the majority's conclusion was based on issues never raised by the appellants.  

* * * *

The three appellants in this appeal, GPG, Trimone, and ELE, import ground fault circuit interrupters ("GFCIs") into the United States.  Pass & Seymour, Inc. obtained an exclusion order from the ITC following the Commission's finding that the devices infringed three patents: 7,283,340; 5,594,398; and 7,164,564. 

On appeal, although the appellants raised "numerous issues" challenging the Commission's determination of infringement, the panel found most of them unpersuasive.  Nevertheless, the majority did conclude that the Commission had erred in some respects, finding that (1) GPG's 2003 and 2006 GFCIs and ELE's 2006 GFCIs do not infringe the '340 patent because they lack a "detection circuit; (2) Trimone's 2006 GFCI's and ELE's 2006 GFCIs do not infringe the '340 patent because they lack the "load terminals" of the patent; and (3) GPG's 2006 GFCI's do not infringe the '398 patent because they perform the function of the "latching means" in a substantially different way than the structure disclosed in the patent.  In all other respects, the court affirmed the lower tribunal's determination.

The disagreement between the majority and dissent is illustrated by their positions on the "detection circuit" claim term, although it permeates the determinations on the other two terms as well.  The Administrative Law Judge construed "detection circuit" to mean "at least one detection circuit having a circuit segment connected between the line terminals and configured to generate a predetermined signal in response to detecting a proper wiring condition, which occurs when the line terminals are connected to a source of AC power.”  Neither ELE nor GPG challenged the construction on appeal; however, they argued that the Commission erred in adopting the ALJ's infringement finding.  The majority agreed that this element was not infringed: 

The construed claims require the “detection circuit” to “generate a predetermined signal in response to detecting a proper wiring condition.” Initial Determination, slip op. at 85 (emphasis added). But as Dr. Harman’s own testimony makes clear, his “predetermined signal” is merely the “current flow” originating from the hot line terminal. J.A. 40,396. The identified circuit does not generate this current; it is the current that comes from the AC power connection. So instead of detecting a proper wiring condition and generating a signal in response, as the properly construed claim requires, the accused GFCIs simply have power to operate, or not. Dr. Harman’s testimony is not substantial evidence to support a finding that ELE’s 2006 GFCIs infringe claims 14, 18, and 30 of the ’340 patent.

(Slip Op. at 9).  The majority applied similar reasoning with respect to GLG. 

In describing both ELE and GPG's arguments, the majority paid particular attention to the dissent's assertion that the appellants did not raise this issue, responding in a footnote that:

The dissent suggests that the parties did not raise this argument, but ELE clearly argued that “[b]y treating the ‘predetermined signal’ as including whatever AC power happens to arrive at a building from the local power plant, the Commission has broadened this limitation beyond all recognition and effectively reads it out of the claim.”

(Slip Op. at 8, fn. 3).

In a strident dissent, Judge Newman took a significantly different view of the ITC decision and majority opinion on appeal:

The Initial Decision of 170 pages and the Commission’s supplemental rulings of 32 pages present a full understanding of the technology, with rigorous discussion of the evidence and extensive analysis, findings, and conclusions. This court now finds its own facts, applies theories that were not raised by any party, uses incorrect standards of review, and creates its own electrical technology contrary to the uniform and unchallenged expert testimony.

(Dissent at 2).  With respect to the majority's "detection circuit" reasoning, after an extensive discussion of the Commission findings, Judge Newman concluded that:

[t]he court creates a theory not proposed by any party, and rules that a signal that originates from the line terminal is not generated by the detection circuit and thus is not “generated.” See Maj. Op. at 9 (“The identified circuit does not generate this current; it is the current that comes from the AC power connection.”). There is no support for this theory. The only signal generated in response to proper wiring as described in the ’340 patent is “generated” in the same way as in the accused devices, that is, the detection circuit uses power from the properly wired line terminals to supply a signal (claim 14) or response (claim 30) that allows the device to be reset. That is how the Commission, and the parties, interpreted the term. The court’s new interpretation of “generate” was not debated and is not briefed.

(Dissent at 8-9).

Notes:

  • I understand that Pass & Seymour is seeking a rehearing and rehearing en banc on the ground that the majority's approach is in conflict with the APA, and intends to raise the argument that the court based its determination on issues not preserved or presented by the parties, thus unfairly prejudicing the party against whom the issues were decided and wasting the resources of the parties and ITC.
  • The Federal Circuit also issued a companion opinion addressing Pass & Seymour's appeal from the ITC's determination that GPG's 2003 devices and Trimone's 2006 devices do not infringe the '398 patent, and that ELE's 2003 and 2006 devices, GPG's 2003 and 2006 devices, and Trimone's 2006 devices do not infringe Patent No. 7,212,386.  The appeal turned on questions of claim construction, with the majority opinion affirming the ITC's constructions largely by applying a "plain meaning" approach.  Judge Newman concurred in the result, but took the position that, with respect to the '386 patent, the majority should have adhered to the Commission's construction, rather then adopting its own construction. 

CHALLENGE.GOV: Prizes as an Additional Incentive Layer

Bits and Bytes, Patent, Science

In my patent law course last week, we had discussion of the role of a patent system as compared with other potential governmental pro-innovation initiatives such as grants or prizes.  Our current patent system does not provide any strong mechanisms for channeling innovation toward particular identified issues.  Rather, investors and inventors choose their own paths according to their own subjective perception of the potential market upside.  When an important challenge is publicly identified, we may want to add an additional layer of incentive to funnel research in a particular direction. In that vein, the Obama Administration's Chief Technology Office Aneesh Chopra and Chief Information Officer Vivek Kundra unveiled CHALLENGE.GOV at yesterday's GOV 2.0 conference.  CHALLENGE.GOV identifies 35 challenges and offers prizes for folks who provide novel solutions.

Identified challenges include:

  • Create nutritious food that kids like — $12,000 prize.
  • Reducing waste at college football games — school prestige award.
  • Best original research paper as judged by the Defense Technical Information Center.
  • Provide a whitepaper on how to improve reverse osmosis membranes — up to $100,000.
  • Digital Forensics Challenge
  • Federal Virtual Worlds Challenge (Create the best virtual world for the US Army) — $25,000 in prizes.
  • Advance the field of wireless power transmission — $1.1M for a team that can wirelessly drive a mechanical climber to 1 kilometer height at a speed of at least 5 meters/sec. 
  • Strong Tether Challenge — create a material with 50% more tensile strength than anything on the market for $2 million.
  • etc.

Best Mode: District Court Improperly Invalidated Patent that Mis-Identified Best Mode

Best Mode, Inequitable Conduct, Patent, Patent Cases 2010

Green Edge Ent. LLC v. Rubber Mulch Etc. LLC (Fed. Cir. 2010)

You might guess from the names of the parties that the subject matter of the dispute is rubber mulch. Green Edge's patent covers a synthetic rubber mulch that is shaped and colored to imitate a natural mulch. In its patent application, Green Edge indicated that a variety of systems could be used to add color to the rubber, but the application also spelled out one particular "VISICHROME" system by Futura Coatings as being the "most preferred" system. It turns out that Futura Coatings never made or sold system under the name of VISICHROME. Rather, the product Green Edge should have identified was "Product Code 24009." The name VISICHROME apparently came from a sales letter from a Futura Vice President who had referred to a VISICHROME system.

Best Mode: During the infringement litigation, the Eastern District of Missouri court held the patent invalid for failure to disclose the best mode under 35 USC § 112 – finding that VISICHROME did not exist and "that Green Edge had concealed the best mode by disclosing 'a misleading, non-existent name instead of the number' when no similar product was available on the market."

Section 112 of the patent act requires that the patent specification "set forth the best mode contemplated by the inventor of carrying out his invention." Federal Circuit precedent has held that such a "best mode" need only be described if the inventors subjectively possessed a best mode on the filing date of the application. Even then, the question is whether the inventor "concealed" the preferred mode from the public.

The second prong asks whether the inventor has disclosed the best mode and whether the disclosure is adequate to enable one of ordinary skill in the art to practice the best mode of the invention. The second inquiry is objective; it depends upon the scope of the claimed invention and the level of skill in the relevant art.

Although not suggested by the statute, the best mode requirement is generally examined on an element-by-element basis. Here, Green Edge clearly had a preferred approach for coloring the rubber pieces and thus was required to disclose that "best mode."

On appeal, the Federal Circuit reversed – holding that the best mode had not been objectively concealed. The court's reasoning was that a competitor looking for "VISICHROME" might have been able to find it around the time of the invention since at least one Futura Coatings executive had been using that name in sales letters.

The disclosure might have, at the time the application was filed, been specific enough to describe the colorant so as to enable a person of ordinary skill in the art to make the claimed product using Futura's 24009 product. The application for the '514 patent was filed in October 1997, and [the Futura VP's] letter describing Futura's "Visichrome" colorant system was written in July 1997. Thus, despite [the VP's] inability to remember why he used the term "Visichrome" in his letter, it is at least possible, even likely, that in October 1997, at the time of filing, someone contacting Futura to obtain the "Visichrome" colorant system would have received a response similar to Jarboe's letter of that July.

In the end, the court held that summary judgment was inappropriate. On remand, a jury could still find the patent invalid on best mode.

Written Description: Description Must do more than Allow PHOSITA to “Envision” the Claimed Invention

Biotech, Enablement, Interference, Patent, Patent Cases 2010,

Goeddel v. Sugano (Fed. Cir. 2010)

When two inventors both claim rights to a single invention, the USPTO is charged with awarding rights to the “first applicant to conceive the invention, provided that [inter alia,] the invention is duly reduced to practice, actually or constructively.” A foreign-filed patent application can constitute constructive reduction to practice “provided that the requirements of §112 are met.”

Sugano filed its original human fibroblast interferon (hFIF) patent applications in Japan in 1979 and 1980 but did not file the claims for the US continuation-at-issue until the 1990s. Meanwhile, Goeddel filed its application in June 1989. In the interference, Goeddel argued that Sugano’s original filings did not provide sufficient disclosure to satisfy the written description requirement of 35 U.S.C. §112 (with respect to the claims being litigated in the interference).

The BPAI (Board) held that Sugano’s 1980 Japanese Application constituted constructive reduction-to-practice of the claims. On appeal, however, the Federal Circuit has reversed – holding that the disputed claims failed the written description test because claimed DNA sequence used to create an hFIF amino-acid sequence was not explicitly defined by the original application.

The Board erred in ruling that priority is established if a person of skill in the art could “envision” the invention of the counts. Sugano argues that this ruling is supported by Enzo Biochem, Inc. v. Gen-Probe Inc., 323 F.3d 956, 968 (Fed. Cir. 2002) and University of Rochester v. G.D. Searle & Co., 358 F.3d 916, 923 (Fed. Cir. 2004), but these cases do not hold that envisioning an invention not yet made is a constructive reduction to practice of that invention. In Enzo Biochem the court confirmed that depositing an actual sample may meet the written description requirement when science is not capable of a complete written description. Enzo Biochem, 323 F.3d at 970. In University of Rochester the court held that the description of the COX-2 enzyme did not also serve to describe all unknown compounds capable of inhibiting the enzyme. University of Rochester, 358 F.3d at 926-27. Precedent in evolving science is attuned to the state of the science, but remains bound by the requirement of showing “that the inventor actually invented the invention claimed.” Bradford, 603 F.3d at 1269; see Fiers v. Revel, 984 F.2d 1164, 1170 (Fed. Cir. 1993).

Sugano had argued that the specific DNA sequence coding for the amino acids was not necessary because a person of skill in the art could have identified the sequence and therefore, it was “unnecessary to spell out every detail of the invention in the specification.” The appellate panel rejected that argument – holding that the DNA itself should have been identified since the DNA sequence was claimed.

Board of Patent Appeals

Academic Studies, Articles and Publications, BPAI, Patent

Although the Board of Patent Appeals (BPAI) is working harder than ever, its backlog continues to rise. The first chart below shows the BPAI’s inventory of undecided appeals in ex parte cases. This only includes fully-briefed appeals whose dockets have been transferred to the BPAI and does not include the thousands of other applications where awaiting briefing. The average timing from notice-of-appeal to appellate decision is 29 months.

PatentLawPic1141

I spoke with BPAI officials who identified the jump in early 2009 as a one-time issue involving the bulk transfer of cases that had been previously delayed.

The next chart shows the number of Ex Parte cases decided each month. The average number of cases being decided each month continues to rise. However, the chart also reveals a high month-to-month variability. That variability is explained by the BPAI judge quota system. BPAI judge performance is primarily judged two times per year, and that process is reflected in a systematic incentive for the judges to do more work in Feburary and August and then less work in March and September.

PatentLawPic1142

Although the BPAI is deciding more cases than ever, inventory continues to rise because more appeals are being filed than ever.

Successor Corporation Held Liable for Default Infringement Judgment Against Predecessor

Doctrine of Equivalents, Patent, Patent Cases 2010

DaewooFunai Electric Company v. Daewoo Electronics Corp. (Fed. Cir. 2010)

In 2004, Funai Electric sued four Daewoo entities for infringement of its patents covering various improved video cassette recorders (VCRs). Funai is a Japanese manufacturer of AV equipment. Daewoo was a historic Korean chaebol that splintered after a financial collapse in the late 1990’s.

Successor Liability: Two of the Daewoo defendants are predecessor companies of the other two defendants. One predecessor-successor pair includes Korean companies and the other pair includes their American counterparts.  At the time of the lawsuit, the two predecessor companies had legally transferred assets to their successors but had not yet ceased operations.  About one-year into the lawsuit, the two predecessor companies stopped participating in the litigation. The district court ordered a default judgment and awarded $8 million in default damages.  Funai then asked that the successor companies be held liable for the liabilities of their predecessors. The district court applied Korean corporate and contract law to hold that there is no successor liability. 

On appeal, the Federal Circuit reversed that judgment — holding that US successor-liability law (actually, New Jersey law) should apply when determining whether the American successor company is liable for the actions of its predecessor. Under New Jersey law, a successor company is liable when the business transfer is simply a “new hat” for the business. Since that was the case here, the Federal Circuit determined that the successor is liable for the default judgment.

The 50–page opinion (including a concurrence by Judge Linn) discussed several other issues. Notably, the opinion provides another example of a prosecution amendment made for purposes “tangential to patentability” and that therefore avoids prosecution history estoppel.

Prosecution History Estoppel: Funai argued that one of its asserted claims was infringed under the doctrine of equivalents (DOE).  Daewoo countered that DOE should be limited under the doctrine of prosecution history of estoppel based on a narrowing amendment made during prosecution of the application. In particular, the patentee had cancelled claims 1 and 2 and then added limitations from those claims into a former dependant claim.  The original claim 1 did not spell-out how insulation would take place while the amended claim indicated that a bearing holder would be “made of an insulating material.”

Under the Supreme Court’s Festo decision, an amendment made during prosecution does not implicate a prosecution history estoppel bar if the “rationale underlying the amendment [bears] no more than a tangential relation to the equivalent in question.”  On appeal, the Federal Circuit recognized the amended claim set as being narrowed, but held that “no estoppel exists” because amendment relating to the insulating material was made for purposes merely tangential to the patentability of the claim. 

It is apparent that the nature of the insulating material was not a factor in the allowance of claim 4, for this aspect was not at issue during prosecution. This limitation is in the category that the Court called “merely tangential” to the prosecution, as discussed in Festo.

The court therefore affirmed the holding of infringement under the doctrine of equivalents.

False Marking Claims: Standing

False Marking, Patent, Rantanen, Standing

By Jason Rantanen

Stauffer v. Brooks Brothers, Inc. v. United States (Fed. Cir. 2010)

Raymond Stauffer brought an action against Brooks Brothers claiming that bow ties sold by the defendant were falsely marked with patents that expired in 1954 and 1955.  Stauffer is a patent attorney who purchased some of the marked bow ties.  The district court granted Brooks Brothers' motion to dismiss for lack of standing, and subsequently denied the United States' motion to intervene.  Stauffer and the United States appealed.

Section 292 states:

(a) . . .
Whoever marks upon, or affixes to . . . any unpatented article, the word “patent” or any word or number importing that the same is patented, for the purpose of deceiving the public
. . .
Shall be fined not more than $500 for every such offense.
(b) Any person may sue for the penalty, in which event one-half shall go to the person suing and the other to the use of the United States.

(emphasis added).  This type of language is called a "qui tam" provision, by which the government  essentially asigns its rights to a private party (the qui tam "relator").  Because the relator is standing in the place of the United States, he or she must prove that the government, as opposed to the relator, satisfies the requirements for standing.  Central to this case was the district court's determination that Stauffer failed to sufficiently allege that the United States suffered an injury in fact from Brooks Brothers' alleged false marking. 

On appeal, the Federal Circuit concluded that the district court had erred on this point:

Congress has, by enacting section 292, defined an injury in fact to the United States. In other words, a violation of that statute inherently constitutes an injury to the United States. In passing the statute prohibiting deceptive patent mismarking, Congress determined that such conduct is harmful and should be prohibited. The parties have not cited any case in which the government has been denied standing to enforce its own law. Because the government would have standing to enforce its own law, Stauffer, as the government’s assignee, also has standing to enforce section 292.

Slip Op. at 9.

The panel rejected Brooks Brothers' reliance on Lujan v. Defenders of Wildlife, 504 U.S. 555, 560–61 (1992), which denied plaintiffs standing under a citizen-suit provision, as relating only to suits against the government itself.  It also rejected the argument that Stauffer's standing depends on whether the alleged injury is proprietary or sovereign, concluding that both types of injury are sufficient to confer standing on the government, and therefore on the relator. 

With respect to the Government's request to intervene, the Federal Circuit determined that the district court  erred in concluding that the government lacked an interest sufficient to intervene as a matter of right under Rule 24(a)(2).  The panel stated that:

Contrary to Brooks Brothers’ position, the government has an interest in enforcement of its laws and in one half the fine that Stauffer claims, disposing of the action would “as a practical matter impair or impede the [gov-ernment’s] ability to protect its interest,” and Stauffer may not adequately represent that interest….As an initial matter, Brooks Brothers does not contest the government’s assertion that Stauffer does not adequately represent the United States’ interest in this case.

Furthermore, the government would not be able to recover a fine from Brooks Brothers if Stauffer loses, as res judicata would attach to claims against Brooks Brothers for the particular markings at issue….Thus, even though, as the district court noted, “the issue of the government’s ability to bring an action pursuant to section 292” in general was not presented,[] the United States’ ability to protect its interest in this particular case would be impaired by disposing of this action without the government’s intervention. We there-ore reverse the district court’s decision denying the government’s motion to intervene.

Slip Op. at 15-16 (internal citations omitted).

Note: The Federal Circuit expressly declined to address several issues, including  the constitutionality of Section 292(b) (an issue that was raised by amicus Ciba Vision Corporation), whether section 292 addresses a proprietary or a sovereign injury, or both, and whether Stauffers alleged injuries to himself, or his asserted injuries to competition, give him standing.  In addition, in its remand the panel explicitly instructed the district court to consider Brooks Brothers' motion to dismiss pursuant to Rule 12(b)(6), which argued that the complaint fails to allege an intent to deceive the public with sufficient specificity.

Federal Circuit Holds-Line on Patent Misuse Defense

Doctrine of Patent Misuse, Infringement, Patent, Patent Cases 2010,

By Dennis Crouch

In a split decision, an en banc Federal Circuit has held that the non-statutory equitable doctrine of patent misuse should be narrowly applied. Here, the court held that an anticompetitive agreement between companies to suppress a given technology would not constitute misuse of a patent covering an alternative technology being promoted by the companies. Thus, the patents can still be enforced. Of course, companies following this pathway could still be liable for antitrust violations.

Princo Corp. v. International Trade Commission and U.S. Philips Corp. (Fed. Cir. 2010) (en banc)

The alleged patent misuse was associated with a CD-R/RW patent-pool arrangement between Philips and Sony. The two companies chose a particular method (Raamaker) of encoding location information on the CD to serve as the standard and then allegedly suppressed another method (Lagadec). (Both methods were covered by patents held by the companies.)

Princo argued here that creation of the patent pool licensing the Raamaker method and the suppression of the Lagadec method constituted patent misuse and should render the patents undenforceable.

Patent Misuse:     

The doctrine of patent misuse is … grounded in the policy-based desire to 'prevent a patentee from using the patent to obtain market benefit beyond that which inheres in the statutory patent right.' Mallinckrodt, 976 F.2d at 704. It follows that the key inquiry under the patent misuse doctrine is whether, by imposing the condition in question, the patentee has impermissibly broadened the physical or temporal scope of the patent grant and has done so in a manner that has anticompetitive effects. B. Braun, 124 F.3d at 1426. Where the patentee has not leveraged its patent beyond the scope of rights granted by the Patent Act, misuse has not been found. See Monsanto, 363 F.3d at 1341 ("In the cases in which the restriction is reasonably within the patent grant, the patent misuse defense can never succeed."); Virginia Panel, 133 F.3d at 869 (particular practices by the patentee "did not constitute patent misuse because they did not broaden the scope of its patent, either in terms of covered subject matter or temporally"). . . .

Given that the patent grant entitles the patentee to impose a broad range of conditions in licensing the right to practice the patent, the doctrine of patent misuse "has largely been confined to a handful of specific practices by which the patentee seemed to be trying to 'extend' his patent grant beyond its statutory limits." USM Corp. v. SPS Techs., Inc., 694 F.2d 505, 510 (7th Cir. 1982).

Recognizing the narrow scope of the doctrine, we have emphasized that the defense of patent misuse is not available to a presumptive infringer simply because a patentee engages in some kind of wrongful commercial conduct, even conduct that may have anticompetitive effects. See C.R. Bard, Inc. v. M3 Sys., Inc., 157 F.3d 1340 (Fed. Cir. 1998) ("Although the defense of patent misuse . . . evolved to protect against 'wrongful' use of patents, the catalog of practices labelled 'patent misuse' does not include a general notion of 'wrongful' use."). Other courts have expressed the same view. See Kolene Corp. v. Motor City Metal Treating, Inc., 440 F.2d 77 (6th Cir. 1971) (There is no such thing as "misuse in the air. The misuse must be of the patent in suit. An antitrust offense does not necessarily amount to misuse merely because it involves patented products or products which are the subject of a patented process." (citations omitted)); McCullough Tool Co. v. Well Surveys, Inc., 395 F.2d 230 (10th Cir. 1968) (the defense of patent misuse has been allowed "only where there had been a misuse of the patent in suit"). While proof of an antitrust violation shows that the patentee has committed wrongful conduct having anticompetitive effects, that does not establish misuse of the patent in suit unless the conduct in question restricts the use of that patent and does so in one of the specific ways that have been held to be outside the otherwise broad scope of the patent grant.

On appeal, the en banc Federal Circuit held that this case does not fit with other misuse precedent. "This case presents a completely different scenario from the cases previously identified by the Supreme Court and by this court as implicating the doctrine of patent misuse." In particular, the alleged misuse was alleged agreement to suppress "an entirely different patent that was never asserted." "Even if such an agreement were shown to exist, and even if it were shown to have anticompetitive effects, a horizontal agreement restricting the availability of Sony's Lagadec patent would not constitute misuse of Philips's Raaymakers patents or any of Philips's other patents in suit."

Reduced to its simplest elements, the question in this case comes down to this: When a patentee offers to license a patent, does the patentee misuse that patent by inducing a third party not to license its separate, competitive technology?

The court answered this question with a resounding "no" – such an action "would not fall within the rationale of the patent misuse doctrine as explicated by the Supreme Court and this court." In particular, the patent-in-suit there must be a direct connection between the patents-in-suit and the alleged misconduct.

Dissent: Judge Dyk (joined by Judge Gajarsa) wrote a 32-page dissent arguing that the patent misuse doctrine should be given teeth:

Evidently the majority thinks it appropriate to emasculate the doctrine so that it will not provide a meaningful obstacle to patent enforcement. . . . Indeed, the majority goes so far as to suggest that the misuse doctrine be eliminated entirely. I read the relevant Supreme Court cases and congressional legislation as supporting a vigorous misuse defense, clearly applicable to agreements to suppress alternative technology. The majority cabins the doctrine in contravention of this Supreme Court authority. I respectfully dissent.

Guest Post: Keys to Hiring Newly-Minted Patent Lawyers

Guest Post, Law School, Patent,

by Thomas G. Field, Jr., Professor, University of New Hampshire (UNH) School of Law (formerly Franklin Pierce Law Center)

There is much ado about generalist and specialty law school rankings, but it is difficult to understand why they should make much difference in hiring new, much less experienced, patent lawyers.

Technical training figures prominently too, but that is difficult to factor in. As has been discussed on this blog, two others and I published a paper concerning the correspondence between the percentage of attorneys with formal training in computer science (our focus) or engineering and the percentage of computer-based patents issued. There we argued, as I strongly believe, that the PTO’s discrimination against computer science graduates is irrational.

The paper also implies that one needs formal training in a particular art to competently draft and prosecute applications in that art. Most patent attorneys would reject the idea. Despite co-authorship, I do too.

I regard the most important technical criteria to be attorneys’ (or agents’) capacity to be educated by inventors and, as one of our alumni put it several years ago, function as a mediator between inventors and examiners. In that regard, I recall the late Robert Shaw. Prior to coming to Pierce in the mid-1970s, where he taught claim drafting and prosecution until he retired, Bob was a full-time attorney for MIT. It’s difficult to imagine that he could have had much expertise with regard to the wide range of applications drafted and prosecuted on behalf of an incredibly sophisticated faculty. Yet there is no reason to doubt the quality of his work for people there or at other universities. I do not envy those who attempt to judge such capacity from college transcripts and unrelated work experience.

Moving from technical to legal training, I regard the most important criteria to be the capacity to identify what decision makers will find critical, spot flaws in opponents’ positions and to argue effectively for their own. Regarding potential clerks, Justice Scalia famously stated, “I’m going to be picking from the law schools that . . . admit the best and the brightest, and they may not teach very well, but you can’t make a sow’s ear out of a silk purse. If they come in the best and the brightest, they’re probably going to leave the best and the brightest, O.K.?” (as quoted by Adam Liptak, On the Bench and Off, the Eminently Quotable Justice Scalia, N.Y. TIMES, May 12, 2009, at A13. If so, what’s gained from the education? There’s also risk of loss. I was struck by the observation that, “For most of the past fifty years, attending Harvard Law School was a miserable experience for the majority of its students.” Kevin K. Washburn, Elena Kagan and the Miracle at Harvard (2010). It is difficult to see how students would be better off for such an experience — unlikely to be unique.

General ranking may be useful for identifying some of the best and the brightest. But many choose schools based on a variety of other factors including cost, effects on partners, and quality of life. It would therefore seem that indicia of drive and intelligence other than that reflected in decisions of law school admissions committees deserve consideration.

In tough economic times, hiring seems more likely to turn on the skills and knowledge candidates have, rather than what they are capable of acquiring. If so, hires may be based on program rankings. But, as I have pointed out at length in Ranking Law Schools’ Special Programs, 50 IDEA 335 (2010), all rankings are suspect, whether based on the number and fame of faculty, the number of specialty courses offered or something else. In that article, at 344, I ultimately wonder whether “anyone other than a fool would favor one candidate over another based on reputations of professors neither candidate may have seen or lists of courses neither may have taken.” You might too.
