New design patents have a term of 15 years from patent issuance — that is a 1 year bump from the 14 year term familiar to many patent attorneys.  The straight 14-year term took hold in 1982.  In the years leading up to 1982, most design patents also had a 14 year term, but applicants had the option of instead obtaining a term of 7 years or 3½ years at a lower fee.  In 1980, all design patents had an application fee of $20, and the issuance fee was $10, $20, or $30, depending upon whether the applicant wanted 3½, 7, or 14 years of patent term.  In 1930, the prices were $10, $15, and $20.

The chart below is a bit hard to read, but it basically shows the percentage of design patents associated with each of the three potential patent terms. The basic result is that in the 1910s, folks were obtaining all three sizes at roughly equivalent rates; By 1940, the short 3½ year term had become most popular; Then, by the 1970s the overwhelming majority of applicants were paying the extra $10 for 14 years.

This is part of a larger project that I’m working through on design patents, and I’ll be able to fill-in the gaps of the chart at a later date.  I’m downloading the TIFF images for these patents; running through OCR  software and then parsing that text output.  It is a bit of a process, and I probably need a multithreaded approach. 

The original design patent Act of 1840 included a 7 year term. I believe it was the the 1861 Act that added the spread term, and included a respective cost of  $10, $15, and $30 with an optional seven additional years.

The patent system has seen tremendous change over the past decade.  A large part of the transformation stemmed from the Leahy-Smith America Invents Act of 2011 that was enacted ten years ago in September 2011.  Earlier this week, I conducted a quick survey of Patently-O readers asking for their thoughts on the impact of the AIA, which has repeatedly been heralded as the largest change to the U.S. patent system since the Patent Act of 1952.  We have about 600 responses.

Most of the survey question used a modified Likert Scale and asked about the importance of various statutory changes found within the AIA.  In order to run some statistics, I transformed the qualitative scale into a linear quantitative scale ranging from 1 (not important) to 5 (very important).

It is not surprising that creation of the Inter Partes Review (IPR) system is seen as the largest change to the system. IPRs have been used to cancel the claims of thousands of patents as obvious — only a small percentage of those would have been found obvious by a jury.   Although almost everyone agreed that IPRs were most important, Patent Attorneys and Patent Agents differed somewhat on other issues, with agents seeing changes to Section 102 as relatively more important to other issues. This included eliminating the date of invention as relevant to patentability and narrowing the pre-filing grace period.  On the other hand, Patent Attorneys gave more weight to PGR proceedings. Patent Office employees were the only ones to say that the addition of satellite offices was important.

The survey included an open-ended response block asking “What else do you have to say about the impact of the AIA?” About 1/3 of responses included these additional thoughts.  My survey tool (Qualtrics) used semantic analysis on these responses and reports that the sentiment expressed was most often generally either “negative” or “very negative.”   (65% Negative or Very Negative; 25% Mixed; 10% Positive or Very Positive).

Some comments focused on the AIA coupled with Eligibility Decisions have “decimated the patent system”; “Devalued IP”; and “greatly reduced the value of U.S. patents” all “to the benefit of large enterprises.” ” A real mess.”

Folks also mentioned the prior user defense; false marking; reducing your own secret prior art; classification system; The new declaration/oath filings was quite costly for applicants.  I’ll publish a more thorough report in the coming days.

by Hon. Michelle Lee. Lee was the Undersecretary of Commerce and Director of the United States Patent and Trademark Office (2015-2017).

The America Invents Act (AIA), which passed on September 16, 2011, brought about some of the most significant changes to our patent system in over 50 years. The Act included an assortment of reforms from a transition to first inventor to file in the United States, the establishment of processes for third party challenges to granted patents at the United States Patent and Trademark Office (USPTO), the creation of the first regional offices of the USPTO, providing inventors the option for accelerated patent examination, and more.

Many of the AIA reforms strengthened our patent system. For example, as a former Director of the USPTO, I cannot overstate the importance of the Agency’s ability to set its own fees and create an operating reserve. This enabled the USPTO to get through periods of government shutdown and to invest in longer-term initiatives such as much-needed information technology upgrades, hire more examiners to reduce the patent application backlog and provide additional training for examiners. The transition to a first inventor to file system was needed to harmonize the U.S. with the rest of the world. The establishment of the first regional offices of the USPTO made our intellectual property system more accessible to all, and of course, prioritized examination, allowing inventors to accelerate the examination of certain patents, makes business sense.

After passage by Congress, the attention turned to the USPTO, and its massive effort to implement the AIA. Then-USPTO Director David Kappos and his dedicated team at the Agency worked hard to implement the AIA in view of numerous proposed rules, soliciting input from stakeholders along the way. By 2013, the USPTO had completed substantially most of the initial AIA rulemaking, including for the post-patent grant review proceedings.

In 2015, I became Director of the USPTO, and the AIA changes had been in place for barely a few years. Leading the USPTO is a great honor that comes with a tremendous responsibility. As a result, I undertook as a priority to assess how these fledgling and complex reforms were going, and to make improvements where needed. Under my leadership, the USPTO continued to solicit feedback on the AIA reforms via numerous requests for comments to proposed rules and stakeholder engagements. This resulted in the implementation of multiple changes, including to the claim construction standard of soon-to-expire patents to be consistent with the (Phillips) standard used in district court litigation, submission of new testimonial evidence with a patent owner’s preliminary response, the addition of a Federal Rule of Civil Procedure 11-type certifications requiring a duty of candor in papers filed in AIA trials to prevent misuse of the proceedings, and more.

As anyone familiar with rulemaking knows, this process takes time, and that is the way it should be, as agency rules (like legislation) have significant and broad impact on all parts of our society. New rules (and laws) should be promulgated deliberately and with all due consideration of input from all stakeholders, driven by data, in compliance with the law, and with compromise to accommodate the often-times disparate and competing needs.

After the patent community had a reasonable period of time to adjust to and experience the many AIA reforms, we began hearing feedback about additional improvements needed to the AIA trials including, for example, in the areas of motions to amend, the claim construction standard and multiple petitions filed at or around the same time on a single patent. As expected for such complex policy and procedural matters, there was often little consensus on whether and what changes were needed. Given this, my team and I at the USPTO believed it important to gather data and broad stakeholder input on these and other issues raised. As a result of these efforts, we came up with a number of proposed changes and drafted proposed rules for comment. For instance, on the claim construction standard, we recognized the awkwardness and inconsistency of having the validity of patent claims construed under one standard in AIA trials, yet a different standard for patent infringement analysis in federal district court, especially when the petitioner in the USPTO proceeding was often the accused infringer in district court. To provide greater fairness and consistency, I thought it important to change the claim construction standard for all patents in AIA trials to the Phillips standard used in federal district courts.

Signing of the DTSA

By this time, it was the fall of 2016 with an election pending. As was customary, the then-current administration asked the USPTO to stop all significant rulemaking to allow the next administration the courtesy of defining and implementing its priorities. So, we had to pull the package of proposed reforms in the midst of being prepared for publication. While not published during my tenure, these proposals, studies and data put the Agency and my successor, former USPTO Director Andrei Iancu, in a better position to implement needed reforms more quickly. I was pleased to see one of the first reforms implemented in the next administration was changing the claim construction standard in AIA trials to that used in district court for all patents.

As I reflect on my tenure on this 10th anniversary of the AIA, the talented USPTO team and I accomplished much, including the establishment of regional offices to better support innovators (especially individual inventors and small businesses), achieving the passage of the Defend Trade Secrets Act of 2016, making initial improvements to the post-patent grant review proceedings while laying the foundation for more, numerous quality initiatives to ensure the issuance of stronger, more reliable patent rights, launching an open data initiative to provide access to the USPTO’s rich data, bringing artificial intelligence to the Agency to improve its operations, and spearheading the All-In-STEM initiative and other efforts to ensure our intellectual property system is more widely accessible to all.

Few people have had the privilege and responsibility of being the steward of this important Agency so critical to American innovation. As we await the nomination of a new USPTO Director, it is important to keep in mind the job of a USPTO Director is to keep a steady hand on the tiller and to make improvements thoughtfully and deliberately, with careful consideration of the law, stakeholder input and the data, recognizing that with complex policies and procedures and competing stakeholder interests, consensus is often difficult to achieve.

Former USPTO Directors Dickinson, Kappos, and Iancu, each of whom contributed to the enactment and/or implementation of the AIA, have all been dedicated leaders who did what they thought best when faced with the many challenges of their tenure. Just as I benefited from the foundations laid and works-in-progress achieved by my predecessors, the next Director will benefit from the cumulative efforts and learnings of all prior Directors. Our intellectual property system, like our innovations, is constantly evolving. Therefore, all stakeholders must constantly work together to achieve a balanced intellectual property system for the benefit of our inventors, economy and society. That is why I chose the dynamic and impactful practice of intellectual property law, and I wouldn’t have it any other way.

US provisional patent applications continue to be popular, with about 170,000 filed each year since 2013.  After filing a provisional, the applicant then has one-year to move the case to a non-provisional or PCT application, and eventually toward patent issuance.

If the applicant does not follow-up with these next steps, the provisional application is abandoned, and the file kept secret. About 40% are abandoned — and that adds up to 1.4 million application files lost to the public.  As you might expect, the abandonment rate depends upon the type of applicant:

• Micro Entity: 78% Abandonment Rate
• Small Entity: 44% Abandonment Rate
• Large Entity: 25% Abandonment Rate

There is a good amount of talk about patent grant rate — what percentage of patent applications eventually end up as issued patents. In general though, I have never seen any grant rate calculation take these abandonment numbers into account.

I was considering calling for a new publication regime; Something along the lines of amending Section 122 with a statement to the effect that Any application that has not already been made publicly available 5-years after its effective filing date will be published by the USPTO.  My problem with an immediate call for publication here is that we cannot really tell whether these abandoned applications include any of the shoulders-of-giants that future innovation might stand upon.  Does a public interest in this unknown information outweigh the private benefit that the patent applicants receive by secrets kept.  Although these applications are all secret, the USPTO does have the power to conduct a study on the files to begin to help us understand their value. We’ll see if I can push the agency in that direction.

In re Midwest Athletics and Sports Alliance LLC (Fed. Cir. 2021)

MASA sued Xerox for infringing 20 different patents that all relate to printer related technology.   The district court felt that 20 patents was too many to handle and so ordered MASA to reduce the number of asserted patents to 8 patents by the summary judgment pre-trial stage; and then further drop down to only 4 asserted patents by trial.  The defendant agreed that the eliminated patents would be dismissed without prejudice and that any applicable statute of limitations would be tolled — allowing later refiling of those claims.

Courts regularly limit the number of claims that may be asserted, but here the district court “acknowledges that it knows of no other court that has similarly found that it has the authority to limit the number of patents that a plaintiff may assert (as opposed to the number of claims) in the context of case management.” MASA petition. Court’s regularly use case-management powers to limit issues brought to trial — and typically push parties to work together to resolve their issues through a sort of negotiation: Plaintiff drops claims / defendant drops defenses or counterclaims.  Here, MASA proposed such an approach “MASA proposed a balanced approach consistent with case narrowing precedent, in which MASA would narrow its infringement case by reducing the number of asserted claims at certain points in the case, and Xerox would narrow its invalidity case by reducing the number of its invalidity theories.”  Id. However, the the court instead ordered MASA to eliminate patents from the case entirely.

MASA argued that the order to eliminate entire patents is different than eliminating particular claims, since each patent offers a discrete cause of action. However, the Federal Circuit has denied MASA’s petition for writ of mandamus.  In particular the court found that the dismissal without prejudice and tolling provide sufficient safeguards and “negate any concern that MASA would be deprived of any substantive or procedural right here.”

In re DMF, Inc. (Fed. Cir. 2021)

The court has denied DMF’s mandamus petition on an interesting post-IPR estoppel question.

DMF sued ELCO Lighting in 2018 for infringing DMF’s U.S. Patent No. 9,964,266.  As is usual these days, ELCO turned-around and filed an inter partes review petition — challenging the patent’s validity based upon a 2011 product catalog (printed publication) that had featured the Hatteras lighting product.  Although the PTAB instituted the IPR, it eventually sided with the patentee in holding that the prior printed publication wasn’t enough render the invention obvious.

Back in the district court, ELCO is seeking again to invalidate the claims based upon the Hattaras lighting product.  The difference now is that they are not simply raising the defense based upon the printed publication but rather are presenting the actual product as prior art based upon it being “in public use, on sale, or otherwise available to the public.”  35 U.S.C. 102.

Section 315(e)(2) estops an IPR petitioner from later asserting in litigation that a “claim is invalid on any ground that the petitioner raised or reasonably could have raised during that inter partes review.”  IPRs are limited only to arguments based upon patent documents and printed publications — and so the actual prior product could not have been used as the basis for the IPR.  The district court went a bit further and found that there must be “a substantive difference” between the publication and the physical product that is “germane to the invalidity dispute.”

Here, the district court found substantive, germane differences.  In particular, the failing of the prior art reference was that the elements of the invention required cobbling together images from different products in the catalog.  The PTAB found that mix-and-match approach improper.  In the district court litigation, ELCO is seeking to use the single product to show each element.

On Mandamus, the Federal Circuit did not delve into whether the substantive-germane legal standard was correct or whether the facts had been properly decided — but did find them not “clearly and indisputably erroneous.”  Further, the court found that mandamus was not necessary — the patentee should wait until final judgment and appeal. “DMF has not shown that a post-judgment appeal is an inadequate remedy for asserting a statutory estoppel argument.”

You may have heard that most US utility patent claims use the open transition phrase COMPRISING.  Here’s the data to support that hearsay. The chart below shows data from independent claims gleaned from issued US patens grouped by patent issue year.

To make the chart, I calculated the percentage of independent claims that include the phrase comprising or comprises or comprise as the first traditional (or only) transitional phrase within the claim text.

Patent courses traditionally talk about the three primary transition phrases:

1. Comprising/Comprises/Comprised of (Open Transition)
2. Consisting of (Closed Transition)
3. Consisting Essentially Of (Hybrid Transition)

In recent patents, fewer than 1% of claims use “consisting of” or consisting essentially of.”  Rather, the biggest non-comprising segment is the category of claims that lack any traditional phrase as shown in the chart below.  These non-traditional claims might use the word “having” or “including” as a transitional phrase, or they might not use any word at all.

Here are a few examples of these non-traditional transitions from 2021 patents:

• One or more non-transitory, computer-readable media having instructions that, when executed by one or more processors, cause a device to: …
• A non-transitory computer-readable medium configured to store instructions that, when executed by one or more processors, cause the one or more processors to perform operations that include:
• A handheld, self contained, air cooled induction heater including …
• A compound or a pharmaceutically acceptable salt thereof, wherein said compound is: …
• A compound, or a pharmaceutically acceptable salt thereof, having the structure of
• A method, by one or more processors, for managing text in rendered images: [No transition at all except for a colon]
• Intermediate of formula B-20 [showing structural diagram of compound and going on to include several markush groups]

In many cases it appears that attorneys may be using the alternative transitions as part of their claim stratification strategy.  Thus, many of the claims relying upon a non-traditional transition sit alongside other claims in the same patent that use “comprising.”

The Supreme Court has strongly supported arbitration as an alternative dispute resolution mechanism.  The Federal Arbitration Act (FAA) codifies this “liberal federal policy favoring arbitration agreements.”  Quoting Moses H. Cone Mem’l Hosp. v. Mercury Constr. Corp., 460 U.S. 1, 24 (1983).  Although the right to arbitrate patent cases is seemingly clear from the FAA, Congress went further in its 1982 PTO appropriations bill to expressly codify the enforcement of arbitration agreements for “any dispute relating to patent validity or infringement.”  35 U.S.C. 294.  Sometimes a party subject to arbitration will still file their dispute in court. At that point, the opposing side will move to stay or dismiss the case and compel arbitration.

The core question in MaxPower Semiconductor (Fed. Cir. Sept 8, 2021), is whether the arbitration agreement can be used to cut-short an inter partes review (IPR) proceeding.  Here, the Federal Circuit effectively sided with the PTO and the patent challenger and refused to compel arbitration. The majority opinion is by Judge Reyna and joined by Judge Chen. Judge O’Malley dissented — arguing that the court failed to live up to the statute:

The majority’s denial of a writ of mandamus in this case allows the Patent Trial and Appeal Board to add a new caveat to Congress’s clear instruction that agreements to arbitrate patent validity shall be “valid, irrevocable, and enforceable”—i.e., except during inter partes review.

O’Malley in Dissent.

Background: MaxPower worked for several years with Rohm Semiconductor to develop RFP power transistor technology. MaxPower obtained the patents and licensed those to ROHM with an ongoing running royalty.  The license included an arbitration agreement.   Money flowed for several years.  Rohm eventually developed a new silicon carbide transistor and privately suggested new product was not covered by the agreement.   At that point, MaxPower provided notice that it was planning to initiate arbitration in 30 days.  ROHM acted first — filing the IPR petition at issue here as well as a lawsuit in N.D. Cal. seeking a declaration of non-infringement of the same patents.  The N.D. Cal. Judge granted MaxPower’s petition to compel arbitration, and the appeal of that determination is separately pending before the Federal Circuit.

The PTAB instituted the IPR — holding that it was not bound by the Federal Arbitration Act or Section 294 of the Patent Act. According to the PTAB, those provisions are tied to civil litigation, not USPTO proceedings.  PTAB explained:

After careful consideration of this issue, we conclude that the arbitration clause is not a reason to decline institution. Even if Patent Owner’s recitation of the facts is true, and even if the question of whether patentability falls within the scope of the agreement to arbitrate is committed to the arbiter, we nevertheless do not find a statute, rule, or policy that would preclude the Office from acting on the Petition.

Institution Decision. MaxPower immediately appealed.

NonAppealable: The first problem with MaxPower’s appeal is the statutory rule that institution decisions are nonappealable.  35 U.S.C. § 314(d). The court also ruled that mandamus  was not appropriate here because it was being used as a “means of avoiding the statutory prohibition on appellate review of agency institution decisions.” In re Power Integrations, Inc., 899 F.3d 1316 (Fed. Cir. 2018). Another way to get to appeal is via the collateral order doctrine, but, according to the court, that doctrine also requires an issue of rights that “will be irretrievably lost in the absence of an immediate appeal.” Apple Inc. v. Samsung Elecs. Co., 727 F.3d 1214 (Fed. Cir. 2013).

The FAA itself also creates a right of appeal for refusing to stay any action subject to arbitration.  However, the right to stay under the FAA is limited to stays of proceedings in Federal Court. As such, that provision also does not apply.

In the end, the Federal Circuit found no authority to hear the appeal, and thus dismissed the appeal and denied the mandamus petition.  The court suggested that it might be able to do something once the IPR concludes and a right to appeal attaches. However, the court also noted that the questions here might all be wrapped-up in non-appealable initiation questions. “If MaxPower is truly not raising matters that are absolutely barred from appellate review under section 314(d) (an issue we need not decide here), then MaxPower can meaningfully raise its arbitration-related challenges after the Board’s final written decisions.”

In dissent, Judge O’Malley would have heard the case on mandamus.  The court’s failure to hear the case “cast[s] a shadow over all agreements to arbitrate patent validity, which, after today, apply only in district courts and not in inter partes review proceedings.”

= = = =

I have not seen the arbitration agreement in this case. But there is usually a big question about whether patent validity and/or infringement are covered by the agreement that is particularly focused on licensing.   The district court’s parallel decision staying its case to await the arbitration outcome is set for Oral arguments in October.  The Judge did not actually determine the question of arbitrability, but rather found that issue was for the arbitrator to resolve.

My Civil Procedure I outline turned out to be the longest outline of my first law school semester. Personally, I was betting on joinder and class actions to contain the most notes throughout the semester. As it turned out, discovery took the “most notes” crown. That makes sense – there’s a lot to discover in a lawsuit! Upon review of my outline, some of these rules started to come back to me.

That includes, of course, Rule 26, which outlines discovery generally and contains rules on the duty to disclose.[1] Wrapped within Rule 26 are details about expert testimony.[2] While Rule 26 didn’t end up wholly dispositive of this lawsuit, it certainly was the final nail in the coffin for an inventor’s testimony through the course of Pandrol USA, LP v. Airboss Railway Products, Inc.[3]

This appeal arose from a summary judgment grant to Pandrol[4] (Plaintiffs-Appellees) over Airboss[5] (Defendants-Appellants), declaring that Airboss failed to show clear and convincing evidence of patent invalidity.[6]

The patent at issue, U.S. Patent No. 5,110,046 (’046 Patent), relates to preventing abrasion on tie rail seats by using a plate designed to absorb abrasion between the rail pad and rail tie.[7] FIG. 1 below shows the abrasion plate (labeled 10) in between the pad (labeled 4) and the tie (labeled 1).[8]

One issue in the appeal centered on the testimony of the ’046 Patent’s inventor, Hartley Young.[9] Normally, an inventor testifies on behalf of the patentee. However, by the time of this lawsuit, Young had taken a job with the defendant, Airboss, and submitted a declaration supporting his new employer’s contention that the patent was invalid.[10] At the district court level, assignor estoppel quickly put a stop to that testimony.[11] The Federal Circuit agreed and noted that exclusion of the inventor’s anti-patent testimony was justified based on “unfairness and injustice.”[12]

Where Rule 26 comes into play is the rest of the testimony.[13] Under Rule 26(a)(2), Airboss was required to file an expert report for Young’s declaration because the declaration contained .[14] This declaration contained Young’s opinion on the patent specification interpretation to be used on other issues in the trial.[15] The district court noted that Young’s testimony falls under Federal Rule of Evidence 702 and requires an expert report.[16] On appeal, the Federal Circuit agreed. Even though Young was an inventor and thus a potential fact-witness, his declaration also “contains expert opinion because he opines on claim construction and interpretation of the original application.”[17]  In the end, the Federal Circuit affirmed district court’s exclusion of Young’s testimony on both the assignor estoppel and Rule 26 grounds, thus putting the final nail in his testimony.[18]

With Young’s testimony excluded entirely, clearly, that evidence could not come in. Many can speculate on what the outcome of this case would have been including Young’s testimony. No doubt that information from the inventor himself would be very relevant and accurate as to factual issues! However, one bullet point in my notes on expert witnesses lays out the base reasoning for this rule: “Essentially making sure experts are qualified and aren’t using ‘quack science.’”

Rule 26 certainly has plenty of moving parts. The overarching tools of discovery have many checkboxes and procedural steps to jump through. Sometimes I wonder how I kept it all straight on my final exam last year!

Elevate your Prosecution

Lubby Holdings v. Chung (Fed. Cir. 2021)

Lubby’s US9750284 covers a vape-pen (“personal vaporizer”). Lubby sued Henry Chung for patent infringement and won at trial with a jury verdict of almost $1 million. On appeal though the Federal Circuit has reversed-in-part — holding that the pre-suit damages were not available under 35 U.S.C. § 287.

In general, the patent laws bar a remedy for any infringement that occurred more than six years prior to the filing of the lawsuit.  “[N]o recovery shall be had for any infringement committed more than six years prior to the filing of the complaint or counterclaim for infringement in the action.” 35 U.S.C. § 286.  Back damages are further limited in by the patent marking statute of Section 287.  That provision calls for a patentee to to mark any “patented article” that it sells or licenses-for-sale with the patent number.  If the patentee sells/licenses-to-sell a product covered by the patent without so marking, then back damages can only be recovered for infringement after the infringer is “notified of the infringement and continues to infringe thereafter.” Id.; See also 35 U.S.C. § 287(a) (“Filing of an action for infringement shall constitute . . . notice.”).

Here, the patent covers an article (a personal vaporizor) and Lubby sells articles that appear to be covered by the patent (the J-Pen).  In this case, Lubby did not disclose its damages computations until the day before trial, and those computations included request for back damages.  The court’s approach is actually to assume marking unless the defense objects with at least some minimal evidence of the lack of marking.  Here, Chung objected on that same day and pointed to the J-Pen’s lack of marking of the patent number.  At that point, Lubby should have presented its evidence of marking. However, Lubby did not present any such evidence at trial.  As such, Lubby “can only recover damages for the period that it provided actual notice,” which is the date that it notified Chung of the infringement.

Chung did have notice that the patent existed, but that is also different than notice of infringement under the statute.  “[T]he actual notice requirement of § 287(a) is satisfied when the recipient is informed of the identity of the patent and the activity that is believed to be an infringement, accompanied by a proposal to abate the infringement, whether by license or otherwise.” SRI Int’l, Inc. v. Advanced Tech. Labs., Inc., 127 F.3d 1462 (Fed. Cir. 1997).

The appellate court ordered a new trial on remand to calculate the post-filing sales numbers that will serve as the appropriate damages award.

Chung also appealed on the merits of the infringement case.  However, Chung did not file a R.50(a) JMOL motion on the issue and therefore lost his primary right to appeal.  Chung did request a new trial under R.59, and the court does have power to hear an appeal of a denial of new trial. However, that standard is much higher — requiring an “absolute absence of evidence to support the jury’s verdict.”  Here, the court found some evidence supporting infringement and thus upheld the verdict.

Data Engine Techs v. Google (Fed. Cir. 2021)

This is an old-school claim construction case.  The district court narrowly construed DET’s claim term “three-dimensional spreadsheet” and consequently ruled that Google does not infringe.  On appeal, the Federal Circuit has affirmed.

DET’s invention here is mainly about adding tabs to a spreadsheet to make it “three dimensional.”   In a prior decision, the Federal Circuit found the claims patent-eligible.  “[T]he claim is directed to a specific method for navigating through three-dimensional electronic spreadsheets. . . . The Tab Patents solved [a] known technological problem in computers in a particular way—by providing a highly intuitive, user-friendly interface with familiar notebook tabs for navigating the three-dimensional worksheet environment.”

Judge Stark had construed the claims prior to his eligibility ruling. On remand, however, Google asked for additional claim construction of the preamble term “three-dimensional spreadsheet” since that aspect of the invention had been critical to the Federal Circuit’s eligibility determination.

The district court did construe the term in a narrow fashion — requiring “a mathematical relation among cells on different spreadsheet pages.”  This construction essentially requires each tab to be a layer in a stack of sheets and that the order of the sheets have mathematical importance.   In the example above the “Salads” layer is one-page away from “Entrees”, and two pages from “Desserts.” A mathematical relationship is necessary to allow for 3-D features such as 3-D ranges. The specification explains that

Three-dimensional spreadsheets allow the user to create a worksheet having cells arranged in a 3-D grid. In this manner, the user can manipulate multi-dimensional ranges, i.e., Solid blocks of cells. This feature has distinct advantages. For example, the user can build a worksheet consisting of multiple two dimensional spreads, define 3-D ranges that span these spreads, and copy a range of rows and columns into each of many 2-D spreads at once. This feature eases difficult choirs, such as consolidation of multiple spreads.

‘259 Patent at Col. 2-3.   Further, in the prosecution history, the patentee distinguished a Lotus-123 prior art reference allowing linking between different pages as not representing a “true 3D spreadsheet.”

One issue here is that the 3D spreadsheet requirement is part of the preamble of the claim, not the body of the claim.

12. [A] computer-implemented method of representing a three-dimensional spreadsheet on a screen display, the method comprising . . .

Ordinarily, preambles are not limiting.  Here, the Federal Circuit though fell back on the nose-of-wax analogy — explaining that the patentee had already pushed the wax in one direction and is now estopped from pushing it back.  Namely, during the eligibility determination, the patentee pushed its case as an improvement to three-dimensional spreadsheets, and the court relied upon those arguments to find the invention eligible for patenting.

Non-infringement affirmed.
