“Untethered to the invention as claimed”

Sunday, November 28th, 2021

by Bill Vobach

The quote for the day comes from the recent Moore/Lourie/Dyk opinion in Mentone Solutions LLC v. DIGI International, Inc. The panel reversed Judge Stark of the District of Delaware with respect to his ruling of patent ineligibility.

Judge Moore writing for the court noted:

The district court held that claim 5 was directed to the abstract idea of “receiving a USF and transmitting data during the appropriate timeslots.” J.A. 7 We do not agree. The district court’s formulation of the abstract idea appears to be a high-level description of how USFs operate in mobile stations using extended bandwidth allocation generally. See ‘413 patent at 1:67-2:8. However, the claimed invention departs from this conventional use through a shifted USF, which breaks the fixed relationship between USFs in a downlink slot and the availability for transmission in the corresponding uplink slot. The district court’s abstract idea fails to mention a shifted USF, nor does it capture the receipt of two PDCH assignments that permit monitoring and detecting the PDCHs for a shifted USF and transmission based thereon. Accordingly, it is untethered to the invention as claimed.

MENTONE SOLUTIONS LLC v. DIGI INTERNATIONAL INC., No. 2021-1202 (Fed. Cir. Nov. 15, 2021)(slip op. at 13)(emphasis added).

This analysis strikes me as an important reminder to be wary of overzealous generalizations of claim language as purportedly being abstract ideas. And, it reinforces the court’s analyses in Visual Memory LLC v. Nvidia Corp., 867 F.3d 1253 (Fed. Cir. 2017) and ENFISH, LLC v. Microsoft Corp., 822 F.3d 1327 (Fed. Cir. 2016):

At the same time, we must not express the basic concept of the claim in a way that is “untethered from the language of the claims.” Enfish, 822 F.3d at 1337. When we assess what the claims are directed to, we must do so at the same level of generality or abstraction expressed in the claims themselves. Id.

Visual Memory LLC v. Nvidia Corp., 867 F.3d 1253, 1263 (Fed. Cir. 2017).

However, describing the claims at such a high level of abstraction and untethered from the language of the claims all but ensures that the exceptions to § 101 swallow the rule. See Alice, 134 S.Ct. at 2354 (noting that “we tread carefully in construing this exclusionary principle [of laws of nature, natural phenomena, and abstract ideas] lest it swallow all of patent law”);

ENFISH, LLC v. Microsoft Corp., 822 F.3d 1327, 1337 (Fed. Cir. 2016).

On a different point, the panel once again treated speed as an important factor in the §101 analysis. The court wrote:

Through this shifted USF, the invention purports to “reduce restrictions affecting extended dynamic allocation with minimal effect on the existing prescript.” Id. at 2:44-46. It allows the mobile station to “transmit up to its physical slot limit.” Id. at 5:17-18. The present invention increases the capacity of networks to communicate data by allowing the network to use timeslots for transmission which, according to the patent, were not available in the prior art. The result is a system capable of a higher rate of data transmission. 

MENTONE SOLUTIONS LLC v. DIGI INTERNATIONAL INC., No. 2021-1202 (Fed. Cir. Nov. 15, 2021)(slip op. at 5-6)(emphasis added).

Like the claim in Packet Intelligence, claim 5 purports to solve a challenge unique to computer networks, or, more specifically, certain mobile stations using extended bandwidth allocation in a network: reducing restrictions to enable additional multislot configurations. It increases the rate of data transmission by enabling the use of timeslots for transmission that were not previously available

MENTONE SOLUTIONS LLC v. DIGI INTERNATIONAL INC., No. 2021-1202 (Fed. Cir. Nov. 15, 2021)(slip op. at 12)(emphasis added).

I will add this case to my earlier post about the disparate treatment of speed for purposes of §103 and §101.

FVRA vs. the Constitution

Saturday, November 13th, 2021

by Bill Vobach

I struggle to understand how the Federal Vacancies Reform Act (FVRA) can authorize a temporary head of the USPTO, who is acting without Senate confirmation, to oversee PTAB decisions. If decisions of the PTAB must be overseen by a principal officer in view of the Appointments Clause of the Constitution, it seems that an unconfirmed temporary head cannot satisfy that role, even on an interim basis. Stated differently, Congress does not have the authority to waive the Appointments Clause of the Constitution on an interim basis.

So, it was interesting to read Justice Thomas’s concurrence in NLRB v. SW General, Inc.:

That the Senate voluntarily relinquished its advice-and-consent power in the FVRA does not make this end-run around the Appointments Clause constitutional. The Clause, like all of the Constitution’s structural provisions, “is designed first and foremost not to look after the interests of the respective branches, but to protect individual liberty.” NLRB v. Noel Canning, 573 U. S. ___, ___ (2014) (Scalia, J., concurring in judgment) (slip op., at 3) (internal quotation marks and bracket omitted). It is therefore irrelevant that “the encroached-upon branch approves the encroachment.” Free Enterprise Fundsupra, at 497 (internal quotation marks omitted). “Neither Congress nor the Executive can agree to waive” the structural provisions of the Constitution any more than they could agree to disregard an enumerated right. Freytag v. Commissioner, 501 U. S. 868, 880 (1991). The Judicial Branch must be most vigilant in guarding the separation between the political powers precisely when those powers collude to avoid the structural constraints of our Constitution.


Courts inevitably will be called upon to determine whether the Constitution permits the appointment of principal officers pursuant to the FVRA without Senate confirmation.

NLRB v. SW General, Inc., 137 S. Ct. 929, 949 (2017).

It will be interesting to see if anybody challenges a post-Iancu/pre-Vidal decision by the PTAB as being unconstitutional for failing to be overseen by a principal officer whose appointment satisfied the Appointments Clause of the Constitution.

The “(cleaned up)” citation

Friday, November 5th, 2021

Have you noticed that in recent opinions the Federal Circuit seems to have adopted the “(cleaned up)” citation when citing “busy” sources. The “(cleaned up)” citation allows a writer to make an argument more forcefully by eliminating some of the distracting citation details that have traditionally been involved in legal writing. For more details, here are some articles discussing “(cleaned up)” [LINK] and [LINK].

Below are some of the recent cases where the Federal Circuit has used “(cleaned up)” in an opinion or order. It appears that Judge Prost and Judge Taranto are far and away the biggest users of “(cleaned up).” Judges Bryson, Chen, Stoll, Dyk, O’Malley, Moore, and Hughes have only used it once or twice. Not surprisingly, Judge Wallach does not appear to have used it yet. During oral argument he is a stickler for accurate quotation from references. It will be interesting to see if “(cleaned up)” is abused and becomes frowned upon.

Judge Cunningham takes the bench

Tuesday, November 2nd, 2021

I believe Monday was the first time that Judge Tiffany Cunningham has sat for oral argument as the Federal Circuit’s newest judge. In her initial panel, she was paired with the Chief Judge and Judge Dyk. I’m not sure if that pairing was the Federal Circuit’s version of hazing or of moral support. Judge Cunningham clerked for Judge Dyk after law school.

Judge Cunningham asked a few questions during the first case for oral argument. You can hear some samples here:

There had been some discussion during the oral argument of not wanting to issue an opinion that ruined the law. During rebuttal, one of the advocates tried to reassure Chief Judge Moore that she would not ruin the law by ruling in his client’s favor. Chief Judge Moore quickly quipped that she knew she wasn’t going to ruin the law. Listen:

Who are the PTAB judges?

Saturday, October 30th, 2021

I was looking for a recording on YOUTUBE of yesterday’s symposium on patent law by the SMU Dedman School of Law and instead ran across this previous symposium session about the PTAB:

One of the interesting tidbits from the video is when Professor Semet shares some of her research about the backgrounds of the PTAB judges. You can see her discussion beginning about the 23 minute mark of the video.

Through a FOIA request and follow-on research she has reviewed the backgrounds of about one half of the PTAB judges and determined the following statistics:

38% are female;

23% were former examiners;

13% were formerly PTAB lawyers or from the USPTO Solicitor’s Office;

19% were former Federal Circuit clerks;

85% have private practice experience;

40% are engineers/scientists;

48 is the median age;

29% attended D.C. area law schools;

74% did not attend T14 law schools.

Here’s a link to an earlier video where Professor Semet discusses the research (beginning about the 10 minute mark) [Link].

I’m surprised by the “40% are engineers/scientists” number. That’s all? Perhaps that statistic is actual work experience as an engineer/scientist, rather than just degree earned.

Patent Law Symposium

Tuesday, October 26th, 2021

There is an interesting virtual symposium scheduled for this Friday. It is being hosted by SMU Dedman School of Law, the FedCircuit Blog, and the Tsai Center for Law, Science, and Innovation.

The three topics look really interesting.

Panel I: The Rise of the Western District of Texas: Forum Selling and Forum Shopping in Patent Trial Courts; Or, the Failure of T.C. Heartland

Panel II: Arthrex, the PTAB, and the USPTO Director’s New (Temporary?) Authority over Patent Opposition Proceedings 

Panel III: The Federal Circuit: Is Its Exclusive Jurisdiction Still Needed Given the Supreme Court’s Renewed Interest in Resolving Disputes over Patent Law?

More details and registration information are available at this [LINK].

I thought the third panel looked particularly intriguing. That panel is focused on the impact of the Supreme Court in patent law and whether there is a continuing necessity for the Federal Circuit. It would seem that there are some other factors at play, as well, when it comes to whether there is a continuing necessity for the Federal Circuit. For example, given the Federal Circuit’s ineptitude in framing a workable rule for §101 that fosters innovation in today’s information economy, is the CAFC really serving the purpose it was designed for? The Federal Circuit hasn’t voted to take a patent case en banc in over three years — again, is it really serving the purpose it was designed for? The Federal Circuit has to rely heavily on Rule 36 Judgments to dispose of its docket of cases. Would it be better to distribute that workload of cases across the other circuits so that the case law could be developed with more written opinions? (I’m just being a gadfly with these questions; but, I do see them as significant failures by the court in recent years.)

Oral Argument of the Day: Tyler Research Corp v. ENVACON, Inc.

Monday, October 25th, 2021

The oral argument of the day is from the CAFC oral argument in TYLER RESEARCH CORPORATION v. ENVACON, INC., No. 2020-2081 (Fed. Cir. Apr. 7, 2021). I enjoyed listening to this oral argument recording because it dealt with forum non conveniens issues. It brought back memories of first year civil procedure class.

You can listen to the oral argument here:

The Rule 36 Judgment is available here: [Link].

Judge Dyk provided a historical overview of forum non conveniens in

Halo Creative & Design Ltd. v. COMPTOIR DES INDES, 816 F.3d 1366 (Fed. Cir. 2016).

Oral Argument of the Day: SmithKline Beecham Corp. v. Apotex Corp. (Jan. 2004)

Tuesday, October 19th, 2021

The Federal Circuit updated its web site the other day. The new oral argument list shows that one of the first oral arguments that was made available to the public by the Federal Circuit web site is from SmithKline Beecham Corp. v. Apotex Corp., 365 F.3d 1306 (Fed. Cir. 2004).

I thought this might be an interesting “Oral Argument of the Day” for several reasons. First, it was one of the last oral arguments made by Ford Farabow of Finnegan Henderson Farabow Garrett and Dunner at the Federal Circuit. Second, Judge Rader (retired) was the presiding judge and he always held lively oral arguments. This is no exception. Third, it was an appeal from a Northern District of Illinois trial where it appears that Judge Posner of the Seventh Circuit sat by designation. Fourth, the claim recited only four words with no preamble: “Crystalline paroxetine hydrochloride hemihydrate.” 

I’m not sure why this oral argument was recorded in January of 2004. Perhaps the Federal Circuit was experimenting with recording oral arguments at that time. During 2006, the Federal Circuit began a regular practice of recording oral arguments.

The opinion for the court is available here: [Link].

One interesting sound bite by Judge Rader, commenting on the district court’s claim construction as being policy driven, is available here:

Quotes for the day

Monday, October 18th, 2021

C.    Review the Claims

The claims define the property rights provided by a patent, and thus require careful scrutiny. The goal of claim analysis is to identify the boundaries of the protection sought by the applicant and to understand how the claims relate to and define what the applicant has indicated is the invention. Examiners must first determine the scope of a claim by thoroughly analyzing the language of the claim before determining if the claim complies with each statutory requirement for patentability. See In re Hiniker Co., 150 F.3d 1362, 1369, 47 USPQ2d 1523, 1529 (Fed. Cir. 1998) (“[T]he name of the game is the claim.”).

MPEP Section 2103 (I)(C).

Finally, when evaluating the scope of a claim, every limitation in the claim must be considered. Examiners may not dissect a claimed invention into discrete elements and then evaluate the elements in isolation. Instead, the claim as a whole must be considered. See, e.g., Diamond v. Diehr, 450 U.S. 175, 188-89, 209 USPQ 1, 9 (1981) (“In determining the eligibility of respondents’ claimed process for patent protection under § 101, their claims must be considered as a whole. It is inappropriate to dissect the claims into old and new elements and then to ignore the presence of the old elements in the analysis. This is particularly true in a process claim because a new combination of steps in a process may be patentable even though all the constituents of the combination were well known and in common use before the combination was made.”).

MPEP Section 2103(I)(C).

Query: Would analogous paragraphs be helpful footnotes for the Federal Circuit’s internal operating procedures?

Decision maker bias

Wednesday, October 13th, 2021

In today’s split-decision in Mobility Workx v. Unified Patents, LLC, I thought the majority decision and the dissent were interesting for their discussion of previous cases and scholarly work describing where there is a potential for decision maker bias to occur. In a cursory review of the decision, I did not see any discussion of the Federal Circuit’s decision in Eolas Technologies, Inc. v. Microsoft Corp., 457 F.3d 1279 (Fed. Cir. 2006). In that case, the Federal Circuit discussed the Seventh Circuit’s practice of reassigning cases to a new district court judge upon remand for retrial from the Seventh Circuit or from the Federal Circuit.

The Seventh Circuit appears unique among the circuit courts of appeals because it sets forth its law on judicial reassignment in the form of a rule. Thus, contrary to Eolas’ arguments, Circuit Rule 36 is not merely an internal glossary for construing silence in Seventh Circuit opinions as a direction to reassign a case on remand. Rather, the Seventh Circuit rule makes reassignment the norm, unless our sister circuit alters the default rule with an express assignment back to the same judge. “The purpose of Rule 36 is to avoid, on retrial after reversal, any bias or mindset the judge may have developed during the first trial.” Cange v. Stotler and Co., 913 F.2d 1204 (7th Cir.1990) (emphases added). Because the operation of Rule 36 avoids “any bias or mindset” that “may have developed,” the law of the Seventh Circuit differs from that of other circuits. See, e.g., Procter & Gamble Co. v. Haugen, 427 F.3d 727, 744 (10th Cir.2005) (“[W]e will remand with instructions for assignment of a different judge only when there is proof of personal bias or under extreme circumstances.”) (internal quotes and citation omitted); Glen Holly Entm’t v. Tektronix Inc., 343 F.3d 1000, 1017-18 (9th Cir.2003) (explaining that reassignment considerations include “whether the district court judge would have substantial difficulty in putting out of his or her mind previously expressed views”); United States v. Microsoft Corp., 56 F.3d 1448, 1463 (D.C.Cir.1995) (explaining that reassignment does not require a finding of actual bias or prejudice, “but only that the facts might reasonably cause an objective observer to question the judge’s impartiality”) (internal quotes and citation omitted).

Eolas Technologies, Inc. v. Microsoft Corp., 457 F.3d 1279, 1283 (Fed. Cir. 2006).

You can read that Federal Circuit opinion [here]. I think it is interesting to note the steps that are taken to avoid the appearance of bias even at a level as high as the district court level.


Tuesday, October 12th, 2021

I’m always interested to see the word “each” come up in claim construction or infringement cases. The Federal Circuit’s decision in Traxcell Technologies, LLC v. Nokia Solutions and Networks OY et al., 2020, 1440, 2020-1443 (Fed. Cir. Oct. 12, 2021) addressed the word “each” again. This time around the court appears to treat the word “each” as merely superfluous and thus providing no distinguishing effect in a doctrine of claim differentiation analysis. That is to say, the court concluded that the various claims all say the same thing, just differently phrased — not to be confused with the various claims saying different things, just differently phrased.

Judge Prost writing for the court stated:

Traxcell first argues that the claims don’t require location to be tied to specific devices. On this point, Traxcell relies on the doctrine of claim differentiation. Because some claims recite the “location for each . . . device,” it says, the claims without “each” do not require per-device locations. But claim differentiation is “a guide, not a rigid rule,” especially if the claim language is clearly to the contrary. Wi-LAN USA, Inc. v. Apple Inc., 830 F.3d 1374, 1391 (Fed. Cir. 2016) (quoting Marine Polymer Techs., Inc. v. HemCon, Inc., 672 F.3d 1350, 1359 (Fed. Cir. 2012)). And Traxcell provides no adequate reason why the mere presence of “each” should have this importance—especially where the various claims all just seem to say the same thing differently phrased. As we explained, each claim recites the location of a device, or “locating” a device. See, e.g., ’284 patent claim 1 (“locating at least one said wireless device”). Not the average of many locations. The fact that some claims require multiple device locations (i.e., locations for “each” device) does not mean that broader claims only requiring a single device location need not be tied to a specific device.

Traxcell Technologies, LLC v. Nokia Solutions and Networks OY et al., 2020, 1440, 2020-1443 (Fed. Cir. Oct. 12, 2021)(slip op. at pages 9-10).

Here are some previous posts where the word “each” came up:

[“Each” — Hard cases make bad law],

[The meaning of “each” ….],

[“Each of a plurality”], and

[Oral Argument of the Month: Timebase v. Thomson].

By the way, I seem to recall that there was another “each” case recently. If I run across it in the future, I’ll add it here.

Do as we say, not as we do.

Tuesday, September 28th, 2021

It is kind of interesting to compare the recent statement in Trust ID v. Next Caller by the Federal Circuit — an intermediate appellate court, rather than a court of last resort — with the Federal Circuit’s Rule 36 practice.

“[T]he Board is obligated to provide an administrative record showing the evidence on which the findings are based, accompanied by the agency’s reasoning in reaching its conclusions.” Alacritech, Inc. v. Intel Corp., 966 F.3d 1367, 1370 (Fed. Cir. 2020) (quoting TQ Delta, LLC v. Cisco Sys., Inc., 942 F.3d 1352, 1358 (Fed. Cir. 2019)). “We do not require ‘perfect explanations,’ and ‘we will uphold a decision of less than ideal clarity if the agency’s path may reasonably be discerned.’” Id. at 1370–71 (quoting NuVasive, 842 F.3d at 1382–83). “We do, however, require that the Board’s own explanation be sufficient ‘for us to see that the agency has done its job.’” Id. (quoting NuVasive, 842 F.3d at 1383). Here, the Board merely partially reiterated and summarily rejected Next Caller’s arguments without explanation. This is not sufficient under the APA and our precedent. NuVasive, 842 F.3d at 1383 (explaining that the Board cannot “summarize and reject arguments without explaining why [it] accepts the prevailing argument.”). Thus, while there is no legal basis to require that the Board have deferred to the examiner’s reasoning, the Board did need to have provided its own reasoning.

TrustID, Inc. v. Next Caller, Inc., 2020-1950 (Fed. Cir. September 27, 2021)(slip op. at 18).

Muddy Metaphysics of Patent Law

Friday, September 24th, 2021

The evening news here in Colorado shared this video clip the other night of some local bears sparring in a mud puddle. I’m not entirely sure how Federal Circuit panel discussions operate immediately following oral argument; but, I suppose it could be something similar to this. Particularly when inventorship rears its head during a case:

One court has said that the “exact parameters of what constitutes joint inventorship are quite difficult to define. It is one of the muddiest concepts in the muddy metaphysics of patent law.”

In re VerHoef, 888 F.3d 1362, 1365 (Fed. Cir. 2018)(quoting  Mueller Brass Co. v. Reading Indus., Inc., 352 F.Supp. 1357, 1372 (E.D. Pa. 1972)).

Quote of the day

Thursday, September 23rd, 2021

The quote of the day comes from the dissent in Scientific Plastic Products, Inc. v. Biotage AG:

It is troubling that the majority and the Board rely on the inventors’ disclosure of the problem their inventions solve as the primary basis for modifying the prior art. This is hindsight of the worst kind, “wherein that which only the invention taught is used against its teacher.” W.L. Gore & Assocs., Inc. v. Garlock, Inc., 721 F.2d 1540, 1553 (Fed.Cir.1983). The patents 1363*1363 do not indicate that leakage was a problem identified in the prior art or a problem known to those of skill in the art. Rather they indicate that the claimed design will avoid leakage. These inventors identified a design problem, articulated it, and solved it. There is absolutely no evidence of the existence of a known leakage problem that would have motivated skilled artisans to modify Yamada. The Board is taking the ingenuity of these inventors and, without any record basis, attributing that knowledge to all skilled artisans as the motivation to make the inventions at issue. Hindsight, hindsight, hindsight.

Scientific Plastic Products, Inc. v. BIOTAGE AB, 766 F.3d 1355 (Fed. Cir. 2014)(J. Moore dissenting).

Senate Confirmation Hearing for Solicitor General Nominee Elizabeth Prelogar

Sunday, September 19th, 2021

The Solicitor General is often referred to as “The Tenth Justice.” I was looking to see if the Solicitor General’s Office had yet filed its requested brief in American Axle and came across this recent Senate confirmation hearing for Solicitor General nominee Elizabeth Prelogar. The introduction begins at the 4:00 minute mark; the questioning begins at the 2:17:20 minute mark.

I thought the discussion of parties that the Solicitor General’s Office consults with before determining its position on a matter, including “agencies with equities” in the matter, was interesting at the 2:36:18 minute mark.
