Federal Circuit Affirms: No Enhanced Damages Against Willful Infringer Who Intentionally Copied

The Federal Circuit last week affirmed a district court’s denial of enhanced patent infringement damages in Sociedad Espanola de Electromedicina y Calidad v. Blue Ridge X-Ray Co., limiting the total damages to just the $852,000 jury award.

In a previous summary of post-Halo cases, we noted the remarkable facts in the underlying trial: the defendants were found to have intentionally copied the plaintiff’s patented design for an x-ray generator and the jury decided that they willfully infringed, but the court declined to award enhanced damages. Instead, the court decided that a brief patent analysis by a senior engineer in Korea was a sufficiently reasonable investigation per HaloIncidentally, according to the plaintiff this engineer “admitted unfamiliarity with basic patent law concepts such as anticipation and claim construction” and “used a Korean-English dictionary to help him review the English language patent.”

Now, we have long advocated that early competitive patent investigation (e.g., freedom to operate) is not only good for innovation but is also a critical component in helping avoid enhanced damages due to willfulness, but this case was still somewhat surprising. After reading through the appellate briefs, the picture is slightly clearer but it suffices to say that we would not recommend modeling your patent diligence policies after this non-precedential case.

We recommend, at a minimum, that the early patent analysis is performed or reviewed by at least one individual who has a fair degree of competence in both the relevant technical field as well as in basic principles of patent law and claim interpretation. That said, this case is still a testament to the broad notion that early patent investigation is looked upon very favorably by courts when deciding on enhanced damages.

What might have happened here?

Based on pure conjecture and without cynicism, I think this case is simply an example of judicial efficiency trumping process. Sure, the plaintiff had a fairly strong willfulness case, but it was also awarded reasonable royalties well in excess of what it actually argued at trial. The final $852,000 jury verdict is nearly three times as much as the highest amount of reasonable royalty damages argued at trial — $297,500. In fact, these excess damages were the subject of the defendant’s JMOL and subsequent cross-appeal at the Federal Circuit.

The district court (and the Federal Circuit, in turn) could have felt that, yes, the jury should not have awarded damages that were so far beyond the argued amount. But the plaintiff did have a pretty good willfulness case, which could have ended up tripling damages in any event. The resulting competing motions, defendant’s motion to reduce the damages verdict and the plaintiff’s request for enhanced damages, each had merit and would have essentially canceled each other out.

Also of note is that it appears that the above-noted characterizations of the engineer’s analysis (unfamiliarity with patent law and consulting a Korean-English dictionary) were not admitted as evidence at trial, so were not considered by the trial court in deciding the motion for enhanced damages.

Conclusion

I don’t want to overstate any takeaways from this particular case because it was, after all, a non-precedential Rule 36 summary affirmance (decision without opinion), but it is still useful and instructive.

The general takeaway is that the Federal Circuit found no abuse of discretion when a trial court denied awarding enhanced damages even when the jury found that the defendant willfully infringed and intentionally copied the plaintiff’s design. The trial court afforded a great deal of weight to the early pre-suit investigation by a senior engineer even though the only evidence of that investigation was a single undated document that included a very brief analysis and conclusion of non-infringement regarding the patent-in-suit.

In practical terms, Sociedad Espanola remains consistent with and supports these best practice points for patent diligence:

  • Certain patents can carry increased risk and should be investigated as soon as practicable after they become known within an organization. Factors that lead to increased risk include, for example, ownership by a close competitor, ownership by a litigious entity, or close proximity in a technical space.
  • The investigation should be performed, either primarily or secondarily, by a person or people with sufficient technical and legal competence. Cases have supported the notion that analysis by an engineer can be sufficient as a “reasonable investigation.” Out of further caution, we recommend that a patent professional, such as an agent or attorney, also perform or at least review the analysis.
  • Review by an attorney can carry the further benefit of establishing a privileged attorney-client communication (an upcoming article will discuss ways to preserve the attorney-client privilege while retaining the option to use the information to defend against willfulness under the new post-Halo paradigm).
  • Track patent analysis in a systematic way so that issues of authenticity and foundation are not in question (the evidence in Sociedad Espanola was somehow admitted, but certainly raised more than a few questions of authenticity/foundation when considering the deposition testimony). Internal policy directives and software tools should align to ensure that a collective patent review effort is best initiated, captured, and preserved.

Willful Infringement Case Update – Eidos Display v. Chi Mei Innolux

Earlier this month, Judge Gilstrap of the Eastern District of Texas issued a post-trial decision penalizing a patent infringer for failing to form a good-faith non-infringement or invalidity position before the lawsuit. The court doubled the $4.1 million verdict for a total of $8.2 million in damages. Eidos Display, LLC v. Chi Mei Innolux Corp., 6:11-cv-00201 (E.D. Tex. Mar. 5, 2018).

This case arose in 2011 when Eidos Display sued a number of defendants alleging infringement of U.S. Patent No. 5,879,958, which related to a method for forming an electro-optical device. Chi Mei Innolux and Chi Mei Optoelectronics (collectively, “Innolux”) were the only defendants remaining when the case went to trial after all of the others settled out.

After trial in mid-2017, the jury returned a verdict finding that Innolux willfully infringed the ‘958 patent and awarded $4.1 million in damages.

Eidos moved for enhanced damages, alleging that Innolux’s conduct was “willful, wanton, malicious, bad-faith, deliberate, consciously wrongful, flagrant, or—indeed—characteristic of a pirate” per the standard set forth in the Supreme Court case Halo v. Pulse (see our earlier discussion of Halo here). As is typical in such cases, the court did not parse the meanings of those flowery words and instead walked through a measured analysis by considering the nine Read factors.

Judge Gilstrap found that five factors favored Eidos’ argument for enhancement, one factor favored Innolux, and three factors were neutral. With the weight of the factors on the plaintiff’s side, Judge Gilstrap opted to enhance the damages by 100%, to $8.2 million, which was short of the fully tripled amount allowed by statute.

Factors favoring enhanced damages:

  • Lack of Investigation or Good-Faith Belief of Non-Infringement/Invalidity (Read factor #2) – This factor weighed the heaviest against Innolux. Innolux’s predecessor (CMO) first learned about the ‘958 patent through one of its customers, Fujitsu, who received infringement claims from the patentholder and “repeatedly asked CMO to undertake a serious analysis.” The court found that no good faith pre-suit investigation occurred and that Innolux had not “formed, prior to this lawsuit, any reasonable non-infringement or invalidity positions.” As such, this factor favored enhancement.
  • Litigation Conduct (Read factor #3) – The court found that Innolux engaged in some degree of discovery misconduct relating to delays in producing documents, waiting until the last minute to resolve disputes, and other gamesmanship tactics. Though the behavior was not so severe as to warrant adverse jury instructions, the court found that it weighed in favor of enhancement.
  • Size and Financial Condition (Read factor #4) – This factor favored enhancement simply because “Innolux is a large company with billions in revenue.”
  • Duration of Misconduct (Read factor #6) – Innolux continued to infringe the ‘958 patent for at least 8 years prior to the filing of the lawsuit. While it attempted to point to Eidos’s delay in bringing suit to justify its behavior, that argument was not persuasive and the court held that “Innolux is responsible for its own actions, including failing to meaningfully investigate the ’958 patent while continuing to infringe it for several years. This conduct supports an enhancement in this case.”
  • Lack of Remedial Action (Read factor #7) – There was no real dispute that Innolux did not take any remedial action after learning of the ‘958 patent.

Factors against enhanced damages:

  • Closeness of the Case (Read factor #5) – The single factor found in Innolux’s favor was supported by the fact that Innolux had previously won summary judgment of invalidity due to indefiniteness, which decision was later reversed by the Federal Circuit on appeal.

Neutral factors:

  • Deliberate Copying (Read factor #1) – Eidos conceded that there was no evidence of affirmative copying.
  • Motivation for Harm (Read factor #8) – “[T]he record lacks evidence that Innolux gained some specific ‘competitive edge’ over LG or Eidos in the marketplace by infringing the ’958 Patent. The record also lacks any indication that Innolux carried on its infringing conduct to gain such an edge or to harm LG or Eidos.”
  • Attempts to Conceal Misconduct (Read factor #9) – To the extent that Innolux’s discovery abuses could be considered an attempt to conceal misconduct, they had already been considered with respect to factor #3. The court did not address any other arguments.

Conclusion

The takeaways from this case are in line with other post-Halo decisions. They stress the importance of conducting early patent investigations and establishing good faith non-infringement and invalidity positions:

  • Ignorance is not bliss when it comes to others’ patents.
  • A solid approach is to adopt a policy of prompt investigation, and to establish reasonable non-infringement or invalidity positions as soon as a relevant patent becomes known by anyone in the company.
  • Evidence demonstrating pre-suit non-infringement or invalidity positions would likely have saved this defendant $4.1 million, and may have led to design-arounds that could have avoided liability entirely.

Willful Infringement: More Clarity From the Federal Circuit — Exmark v. Briggs & Stratton and More

The Federal Circuit’s recent decision in Exmark v. Briggs & Stratton echoes the central point in our prior analysis of Halo v. Pulse that timing matters in determining whether an accused infringer did so willfully. The case leaves us with two key practical implications:

  • Early investigation of patent threats can help avoid a finding of willful infringement; positions developed at the time of litigation are too late and irrelevant.
  • Prior art-based invalidity positions can form the basis for a subjective intent sufficient to defeat willfulness.

Case Summary

Exmark sued Briggs for infringement of U.S. Patent No. 5,987,863, relating to high-end lawn mowers. After a jury trial, the Nebraska district court awarded $48 million to the plaintiff after doubling the damages as a result of willful infringement. Notably, the trial took place before the Supreme Court’s decision in Halo v. Pulse, which meant that the district court applied the now-overruled Seagate standard for willfulness. After determining that Briggs’ defenses were objectively unreasonable, the trial court precluded Briggs from presenting prior art evidence at trial. Briggs’ hope was to use the prior art evidence to support a subjective state of mind that lacked willfulness.

On appeal, the Federal Circuit held that the trial court’s finding of objective unreasonableness did not comport with the Halo standard, which only requires consideration of subjective intent. The court further found that Briggs should be allowed to present prior art evidence in a new trial, conditioned on the timing at which Briggs considered it:

The district court must reconsider its decision to exclude evidence of the prior art during the jury trial on willfulness to determine whether Briggs had developed any views about the prior art at the time of accused infringement or whether the evidence only relates to Briggs’ litigation-inspired defenses.

The Federal Circuit vacated the damages award and the enhancement due to willfulness, and remanded to the district court for a new trial on those and other issues.

Analysis

The Exmark case is a straightforward but significant application of the willfulness doctrine after the Supreme Court’s standard-shifting decision in Halo v. Pulse. In Halo, the Court made it easier for a patentee to obtain enhanced damages from a willful infringer by rejecting the “objectively reckless” prong while also lowering the burden of proof from “clear and convincing” to “preponderance of the evidence.” In practice, the former standard allowed even blatant copiers to escape liability for enhanced damages if they could come up with a reasonable non-infringement or invalidity position at the time of litigation. Now, the focus is on the subjective knowledge, intent, and behavior of the infringer at the time of infringement.

Cases following Halo have begun to shape the new willfulness doctrine. While Exmark does not include an extensive discussion regarding willfulness, the takeaways are clear. If Briggs could have shown that it had developed prior art-based invalidity positions when it allegedly committed the infringement, then it would have been able to use that evidence to prove a lack of subjective willfulness and avoid enhanced damages. But if no pre-litigation analysis had taken place, then the trial court would exclude the prior art evidence, and Briggs would likely be liable for up to three times the jury’s damages verdict.

Other Recent Cases

In Presidio Components, Inc. v. Am. Tech. Ceramics Corp., 2016-2607 (Fed. Cir. Nov. 21, 2017), the Federal Circuit affirmed the district court’s denial of enhanced damages even when the jury determined that the defendant willfully infringed. An engineer for ATC knew about the patent-in-suit for years, which knowledge contributed to the jury’s finding that ATC behaved with reckless disregard. However, due to a later re-examination that resulted in amended claims, the period of infringement was set to begin on a later date — a time when the parties were already well into litigation (the court had issued claim constructions and ATC had developed its defenses). So while the jury found that ATC’s conduct was willful, the district court recognized these “unique circumstances” and ultimately declined to enhance damages because, looking at ATC’s conduct after the relevant date, the case was a “garden-variety” patent infringement action. Had the patent not undergone a re-exam that ended up resetting the infringement period, logic suggests that enhanced damages would have been much more likely.

In Tinnus Enterprises, LLC, Zuru Ltd. v. Telebrands Corporation, 6:16-cv-00033 (E.D. Tex. Nov. 21, 2017), several defendants are currently staring down the barrel of potential liability of up to $36 million (if trebled) after a recent jury verdict of willful infringement. The facts of the case relating to willfulness have not yet come to light, as much of the briefing and trial records are under seal, but we will monitor the case as it makes its way through post-trial motions and appeal. This is a high-profile case against a so-called “knock-off company” that has garnered much attention.

Pirates Among Us? How Have Courts Treated Willful Infringers in the Year Following Halo v. Pulse?

 

As the Supreme Court’s Halo decision[1] recently celebrated its first anniversary, we take a look to see whether the lower courts have effectively rooted out the “wanton and malicious pirates” about whom the unanimous High Court was so gravely concerned. Have we found and singled out our swash-buckling ne’er-do-wells for public shaming, or have we discovered that the label, if defined by the reduced willfulness standard set out in Halo, might suggest that even some of the best-intentioned among us might be keeping parrots in their desk drawers and their closets well-stocked with puffy shirts? And importantly, what can we do to trade those bandannas for halos in the eyes of the court?

Recap

In Halo v. Pulse,[2] the Supreme Court made it easier for a patentee to obtain enhanced damages from a willful infringer under 35 U.S.C. § 284. The Court rejected a part of the previous requirement, under Seagate,[3] in which the patentee had to show that the infringer acted “objectively recklessly.” It also lowered the burden of proof from “clear and convincing” to “preponderance of the evidence.” In practice, the old standard allowed even willful infringers to escape liability for enhanced damages if they could come up with a reasonable non-infringement position even as late as during litigation. The Court felt that this standard was too rigorous. It ratcheted back the necessary showing to, essentially, “egregiousness,” which is centered on the subjective knowledge, intent, and behavior of the infringer.

To that end, courts will consider the nine so-called Read factors[4] in considering whether to award enhanced damages. In terms of guiding behavior outside the context of a specific dispute or litigation, three of these factors are most salient here:

  • Read Factor #1: Whether the infringer deliberately copied the patentee’s ideas or design.
  • Read Factor #2: Whether the infringer, upon knowing of the patent, investigated the scope of the patent and formed a good faith belief that it was invalid or that it was not infringed.
  • Read Factor #7: Remedial action taken by the infringer.

Enhanced Damages After Halo

If one pattern clearly emerges, it is that courts disfavor infringers who “know” about a patent but do not conduct an analysis of the scope of its claims (Read factor #2). Mere knowledge of a patent is generally not sufficient in itself to find willfulness, but knowledge in combination with copying and malicious intent, with no investigation, has proven extremely dangerous.

In Dominion v. Alstom, a Pennsylvania district court found that seven of the nine Read factors weighed in favor of enhanced damages against the defendant.[5] The court doubled the reasonable royalty findings to $972,000. The court found evidence of copying over a long period of time and took particular issue with the fact that “Alstom’s belief it did not infringe . . . is based entirely on the opinion of people without expertise in reading patent claims. On balance, it is not a good faith belief in non-infringement.”[6] The court noted that Halo played a role here and may have ultimately led to Alstom’s downfall. During the course of infringement, Alstom was operating in a Seagate world where an infringer can avoid enhanced damages if they can “muster a reasonable (even though unsuccessful) defense at the infringement trial.” But the Halo ruling did away with that post hoc safe harbor and essentially requires a good faith belief of non-infringement during the actual period of infringement.

In Imperium IP Holdings v. Samsung, an Eastern District of Texas court tripled jury verdict damages to nearly $21 million due to willfulness, the maximum enhancement allowed. The crux of the decision was that, “despite knowing of Plaintiff’s patents since at least April 2011, Defendants never undertook any serious investigation to form a good-faith belief as to non-infringement or invalidity.”[7] In deciding Samsung’s JMOL motion, the court reiterated that “evidence offered at trial established that Defendants had pre-suit knowledge of the patents-in-suit and took no steps to avoid infringement after becoming aware of the patents.”[8]

SRI International v. Cisco Systems also involved large damages numbers.[9] There, the Delaware trial court doubled the jury’s damages verdict to award more than $46 million to the plaintiff. Again, the court was swayed by a finding that the defendant did not perform a sufficient analysis of known patents, noting that evidence showed “that key Cisco employees did not read the patents-in-suit until their depositions.” The fact that Cisco knew about the asserted patents but did not investigate the technical aspects relating to infringement led to more than $23 million in additional damages.

How have defendants avoided enhanced damages?

Here is where the contrast becomes sharp. Even in cases where the Read factors might suggest some troublesome behavior, like knowing and intentional copying, defendants were spared enhanced damages because they made a reasonable investigation at the time of infringement.

In Greatbatch Ltd. v. AVX Corp.,[10] a Delaware district court found no willfulness in relation to three patents infringed by AVX. Even though AVX knew about all three patents at the time of the culpable activity, the court held that the conduct was not egregious or wanton because AVX performed a reasonable investigation at the time. The court distinguished a Federal Circuit case in which enhanced damages were awarded by noting that “here, by contrast, AVX sought and obtained invalidity and non-infringement opinions of counsel before litigation and developed designs and processes to avoid infringement” (court’s emphasis).[11] AVX relied upon opinions of counsel with respect to two of the three asserted patents, and “made significant efforts to avoid infringement of the [third] patent” (i.e., design around) according to the court.

In another remarkable case, Sociedad Espanola de Electromedicina y Calidad v. Blue Ridge X-Ray Co.,[12] the jury explicitly found that the defendants “knowingly and intentionally copied Sedecal’s transformer,” and the court upheld a finding of willful infringement.[13] However, the trial court has discretion to award enhanced damages even when infringement conduct is egregious and willful. Using this discretion, the court appreciated that the defendants “conducted a reasonable investigation of Sedecal’s patent claims and made a good faith determination that the patent was not infringed by their activities and that the patent was likely invalid,” and did not enhance damages. In other words, the defendants here blatantly copied the plaintiff’s product but escaped increased willfulness liability because they made the pre-suit effort to formulate reasonable (though ultimately incorrect) non-infringement positions. In this case, the pre-litigation investigation was conducted by a head engineer.

Similarly, in Koninklijke Philips v. Zoll Medical,[14] a plaintiff’s request for enhanced willfulness damages was rejected on summary judgment because the defendant had evaluated the asserted patents before the lawsuit and established a reasonable non-infringement position. After a portion of the case was appealed, the court quoted the Federal Circuit’s binding finding “that [although] Zoll’s claim construction argument against the jury’s direct infringement verdict . . . was incorrect, [its] argument was based on a reasonable interpretation of the claims in light of the specification and the prosecution history. . . . [T]his belief in non-infringement was reasonable . . . .”

Conclusion

An important practical result here is that Halo has effectively shifted the point in time at which an accused infringer should establish reasonable non-infringement or invalidity positions. We can no longer rely upon arguments that were first conjured up after being sued. By and large, future patent defendants stand a good chance of avoiding enhanced damages if they have a process in place to competently evaluate asserted patents at an early stage. They should have systems to collect relevant information such as analysis, documents, technical information, and relevant discussions in order to bolster a good faith belief of non-infringement or invalidity. That, or else they may find themselves walking the plank.

Three Keys to Effective Freedom-to-Operate Management

Freedom-to-operate is a murky world where the quality of the investigation greatly depends on the skills and resourcefulness of the lawyer or analyst doing the work. Best practices and standards of care are not very well defined and, even when systems exist, they are rarely adaptable to changing needs.

It is our mission at ClearstoneIP to gather, implement, and standardize best practices in FTO and patent risk management. This article is a step in that process and sets forth three basic foundational concepts for effective FTO management.

  1. Well-defined product parameters. For an effective FTO investigation, it is important to define the product or project parameters at the outset. FTO is necessarily carried out with regard to a specific subject. Thus, the analyst should create or ascertain a detailed definition of the product, process, system, or future concept that is being cleared  in order to memorialize the current state of the product. This contrasts with the sort of “invention harvesting” that might be done as part of growing a patent portfolio, where the goal is to identify broad inventive concepts and build on them in creative, but not necessarily actualized, ways. In FTO, the more that is known about the actual product intended to be sold, the more effective the investigation will be. Also, as a product evolves over time, past FTO analysis on that product may change radically. We should document parameters and features at a specific point in time in order to establish a clear historical record.
  2. Patent analysis must focus on the claims. More critically than perhaps any other activity in patent law, an FTO investigation must be centered on patent claims. Prior art patents might include any number of embodiments, alternatives, and everything else under the sun in its specification, but the claims define the exclusive rights. If we can point to a single element of a claim that is not present in the product being investigated, then the claim is cleared and we can move on. There may be some exceptions to this when, for example, we’d want to monitor a cleared patent and its family when the subject matter is particularly close. But the point remains that infringement analysis is all about the claims. Losing sight of this, and using systems that make it difficult to access and act upon claims, can result in inefficiency and wasted time.
  3. A mechanism to tie products to claim determinations. Building on the first two keys, it follows that the investigation would fall apart if we don’t use an effective mechanism to track, memorialize, and manipulate our work product. If we only had one simple product that never changed, this part wouldn’t be too difficult. But as products become more complex, upgrades and modifications are implemented, and product lines grow larger, our need for a robust system to handle the different permutations of product-analysis combinations becomes critical.

There is, of course, much more to the process, such as how to locate relevant patents, how to properly interpret patent claims, when to dismiss patents or merely flag them for monitoring, how to strategically assess relative risk among critical sets of patents, and more. We will touch on specific nuances and more in-depth analysis techniques in future articles.

Accuracy and Speed in Patent Infringement Searching Need Not Be “One or the Other”

“Faster and better results at lower cost!”

A claim so common it blends in with the hum of office chatter. We’d like to believe that patent searches could be turned around within a day or two, but it typically takes much longer.  We’d like to believe that the work returned to us includes everything we need to know.  But, at some level, we sense there are shortcomings.

This is particularly true in the case of freedom-to-operate investigations (FTO).  Searchers often fail to consider certain product features.  Claims are not always afforded their full scope.  And sometimes key patents are just plain missed.  Despite relying on highly competent and experienced analysts, “faster, better and cheaper” just does not seem a reality.

But a departure from conventional methods can overcome the trade-off between speed and accuracy. We can achieve both.  Clearstone Elements is that departure.

Why is there a speed/accuracy trade-off when using conventional search methods?

Imagine for a moment that you have been asked to carry out an FTO analysis.  Let’s also say that, as is often the case, you must complete this analysis under budget, say $3,500.  Assume a billing rate of $75/hour (you have overhead and a boss) and that you’re able to review a patent every 6 minutes.  That means you only have budget to manually review about 470 patents.

This might seem like a reasonably-sized lot.  However, experienced FTO searchers would likely feel that it’s not nearly enough to guarantee a high level of recall (i.e., the ratio of the number of relevant patents retrieved to the total number of relevant patents), say of about 95%.  This will of course vary case-by-case.  But, for many competitive industries, you’d need a starting set in the range of about 2,500-5,000 patents to achieve a sufficiently high recall.

Why must so many patents be manually reviewed in FTO?

Certainly, products don’t typically infringe thousands of patents.  Else, industries would come to a grinding halt.  Indeed, out of a robust set of patents to be reviewed, a searcher is likely to only uncover a handful of relevant ones.

The short answer to the above question is that it’s very difficult for a searcher to anticipate whether a patent is relevant without actually reading and understanding its legal claims.  Products may be described in countless ways, many of which will go unnoticed to a searcher.  Claims of a patent may be written in much broader terms than used to describe the specific embodiments of the patent’s technical disclosure.  For these and other reasons (see here for more information), conventional search tools are imprecise blunt instruments in the FTO context.  Thus, a broad net must be cast.

It should now be obvious why inaccuracy seeps in.

A searcher will typically approach a search with the best of intentions, considering every angle of attack.  Patent classes will be reviewed, important ones selected and queried.  Key assignees will be queried.  Citation, clustering, and family analysis will be conducted on patents flagged as relevant.  Natural language queries, perhaps using semantic analysis, will also be applied relating to key product features.

These tools are all great at robustly representing technology areas.  However, most likely, this aggregation will far exceed, in number, what could be reviewed under budget in an FTO context.  Accordingly, the searcher will necessarily have to take additional steps to downsize this set.  And this is where it goes awry.  The searcher may do as follows:

  1. limit all results by requiring the inclusion of certain key terms;
  2. exclude unknown or small-scale assignees;
  3. exclude patents based on Title, Abstract and/or Drawings; and/or
  4. limit patents by relevancy score cut-off (if relevancy scores are provided).

These processes are generally arbitrary in nature and bare little correlation with relevance.  They are simply not sound bases for reducing a large aggregation of patents in an FTO search.  Inevitably, they cause omission of critical patents.

How does Clearstone Elements overcome this dilemma?

Clearstone Elements is a fundamentally unique search platform.  In Clearstone Elements, associations between patents and technical attributes are memorialized, forming specialized data files called workspaces.  Notably, these technical attributes are associated with patents on the basis of their claims and using human analysis.  These attributes (or elements) are then presented to a searcher as an interactive taxonomy.  A searcher may than effortlessly eliminate swaths of patents from a robust patent set by selecting elements not embodied by the product undergoing search (more on this process here).  In contrast to the arbitrary procedures discussed above, the Clearstone process is objective, reliable, and deliberate.

In fact, current users of Clearstone Elements are typically able to reduce a robust patent set by 90-95%.  This means that, once a workspace is put in place, provided the same constraints as in the above example, a searcher using Clearstone Elements is actually able to objectively consider upwards of 4,700-9,400 patents.  We are essentially empowering searchers to cast significantly broader nets with significantly reduced manual effort.  By replacing the conventional tools that are blunt and arbitrary with Clearstone Element’s logic-based reduction process, “faster, cheaper and more accurate” is no longer an empty promise.
