Claim Duality: Multiple Dependent Claims Can Be Both Patentable and Unpatentable

By on Mar 9, 2023
Posted In

Addressing, for the first time, the issue of patentability of multiple dependent claims under 35 U.S.C. § 112, fifth paragraph, the Director of the US Patent & Trademark Office (PTO) granted rehearing and modified the Patent Trial & Appeal Board’s (Board) Final Written Decision after finding that the patentability of a multiple dependent claim should be considered separately as to each of the claims from which it depends. Nested Bean, Inc. v. Big Beings US Pty. Ltd. et al., IPR2020-01234 (PTO Feb. 24, 2023) (Vidal, Dir.) (precedential).

Nested filed a petition for inter partes review challenging claims 1 through 18 of a patent owned by Big Beings. Claims 1 and 2 were independent, and claims 3 to 16 were multiple dependent claims, which depended directly from either claim 1 or 2. The Board granted institution and ultimately issued a Final Written Decision finding that Nested did not establish that claims 1, 17 and 18 were unpatentable, but that Nested had established that claims 2 through 16 were unpatentable.

Big Beings filed a Request for Director review, noting that each of claims 3 to 16 were multiple dependent claims that depended from both claims 1 and 2. Big Beings argued that because the Board found that Nested failed to show that claim 1 was unpatentable, the Board should have also found that Nested failed to show that claims 3 through 16, as depending from claim 1, were unpatentable. The Director granted review.

35 U.S.C. § 112, fifth paragraph, states, in relevant part, “[a] multiple dependent claim shall be construed to incorporate by reference all the limitations of the particular claim in relation to which it is being considered.” Big Beings argued that the statute requires the Board to separately consider the patentability of alternative dependencies of a multiple dependent claim. Nested responded by arguing that the statute should be read so that if any version of a multiple dependent claim is found unpatentable over the prior art, then all versions of the claim should be found unpatentable.

The Director found that this was an issue of first impression. Relying on 37 C.F.R. § 1.75(c) and 35 U.S.C. § 282, the Director concluded that “a multiple dependent claim is the equivalent of several single dependent claims. Thus, in the same way that the unpatentability of multiple single dependent claims would each rise or fall separately, so too should the dependent claims covered by a multiple dependent claim.” The Director also noted that the Federal Circuit in Dow Chemical and Dayco Products explained that “not addressing claim validity on an individual basis is an error and contravenes 35 U.S.C. 282[.]” The PTO Director concluded, quoting the Manual of Patent Examining Procedure (MPEP), that “a multiple dependent claim must be considered in the same manner as a plurality of single dependent claims.”



Patenting a Nice Cool Glass of Nicotinamide Riboside? Claims Covering Milk Invalid under § 101

By on Feb 23, 2023

The US Court of Appeals for the Federal Circuit found that claims covering a naturally occurring composition were not patent eligible under 35 U.S.C. § 101 merely because one component of the composition had been “isolated.” ChromaDex, Inc. v. Elysium Health, Inc., Case No. 2022-1116 (Fed. Cir. Feb. 13, 2023) (Chen, Prost, Stoll, JJ.)

ChromaDex sued Elysium (a former ChromaDex customer) for infringement of its patent directed to dietary supplements containing nicotinamide riboside (NR). Elysium moved for summary judgment, arguing that the asserted claims were invalid under the § 101 prohibition against patenting natural phenomena. After the district court granted summary judgment, ChromaDex appealed.

The asserted claims were directed to a composition comprising:

  • Isolated NR
  • One or more of tryptophan, nicotinic acid or nicotinamide
  • One of 22 carriers
  • Increased NAD+ biosynthesis after eating.

Both parties conceded that milk satisfies every element of the asserted claims with the exception that its NR is not “isolated.” Both parties also conceded that milk is a naturally occurring material and thus not patent eligible under § 101.

On these facts, the issue presented was whether the claim limitation that the NR must be “isolated” (which does not occur in nature) was sufficient to make the claims patent eligible. The Federal Circuit responded “no.”

The Federal Circuit analyzed the asserted claims under two tests: the “markedly different characteristics” test set out in Chakrabarty, and the Alice two-step test (unsure whether Chakrabarty remains controlling precedent).

Under the Chakrabarty test, a claimed composition is not a natural phenomenon if it has “markedly different characteristics” from what occurs in nature. The Federal Circuit found that ChromaDex’s claimed composition had no markedly different characteristics from natural milk. While ChromaDex argued that isolation potentially allowed for unnaturally high concentrations of NR, the claims did not require such concentrations. The claims included compositions structurally and functionally identical to milk and therefore failed the “markedly different characteristics” Chakrabarty test.

Proceeding to the two-part Alice test, under step 1 the Federal Circuit found that the claims were directed to a product of nature because there were no structural differences between the claimed composition and natural milk. Under step two, the Court found that there was no “inventive step” because the claims were merely directed to increasing NAD+ biosynthesis, which was a natural principle that resulted from drinking milk.

Practice Note: During claim drafting, care should be taken to avoid claims that encompass all structural and functional components of a naturally occurring material.



Delayed Disclaimer: Patent Owner Arguments Made during IPR Not a Claim Limiting Disclaimer in That Proceeding

By on Nov 29, 2022
Posted In

Repeating a conclusion from an earlier non-precedential opinion in VirnetX, the US Court of Appeals for the Federal Circuit held that the Patent Trial & Appeal Board (Board) need not accept a patent owner’s arguments as a disclaimer in the very same inter partes review (IPR) proceeding in which those arguments are made. CUPP Computing AS v. Trend Micro Inc., Case Nos. 2020-2262, 2020-2263, 2020-2264, at *11 (Fed. Cir. Nov. 16, 2022) (Dyk, Taranto, Stark, JJ.)

CUPP Computing is the owner of three related patents each entitled “systems and methods for providing security services during power management mode.” After CUPP sued Trend Micro for patent infringement, Trend Micro filed petitions for IPR against all three patents, asserting that several claims of CUPP’s patents were obvious over two prior art references. The Board instituted all three IPR and found all challenged claims unpatentable as obvious. CUPP appealed.

The Federal Circuit affirmed the Board’s conclusions. The principal issue concerned CUPP’s argument that the Board erred in claim construction. In CUPP’s view, all of the evidence required the claimed “security system processor” be remote from a “mobile device processor.” The Court rejected CUPP’s arguments. Starting with the claims, the Court found that they simply required that the two processors be different. Although some claims required the security system to send a wake signal to or communicate with the mobile device, that language did not support CUPP’s remoteness construction. As the Court explained, just as an individual can send a note to oneself via email, a unit of the mobile device can send signals to and communicate with the same device. Indeed, some of the claims teach communication via an internal port of the mobile device, which was consistent with a preferred embodiment disclosed in the specification in which the two processors could be within the same mobile device.

The Federal Circuit then addressed CUPP’s disclaimer arguments. The Court agreed with the Board that CUPP’s statements made during the original prosecution were far from clear and unmistakable, being susceptible to several reasonable interpretations that are contrary to CUPP’s construction. The Court also agreed with the Board that CUPP’s arguments during the Trend Micro IPRs do not qualify as a disclaimer for purposes of claim construction. While a disclaimer made during an IPR proceeding is binding in subsequent proceedings, the “Board is not required to accept a patent owner’s arguments as disclaimer when deciding the merits of those arguments.”

As the Federal Circuit explained, expanding the application of disclaimers to the proceedings in which they are made—as CUPP proposed—is rife with problems. IPR proceedings are more similar to district court litigation than they are to initial examination, and it is well established that disclaimers in litigation are not binding in the proceeding in which they are made. Further, CUPP’s proposal would effectively render IPR claim amendments unnecessary, as patent owners would be free to change the scope of their claims retrospectively without regard to the protections provided by the IPR claim amendment process, such as [...]

Remote Employees Support Patent Venue

By on Oct 13, 2022
Posted In

In a per curiam opinion, the US Court of Appeals for the Federal Circuit denied a petition for a writ of mandamus seeking to direct the district court to dismiss or transfer the underlying case based on improper venue. In doing so, the Court pointed to remote workers residing in the district to find satisfaction in the venue statute. In re Monolithic Power Systems, Inc., Case No. 22-153 (Fed. Cir. Sept. 30, 2022) (Lourie, Chen, Stark, JJ.) (per curiam) (Lourie, J., dissenting)

Bel Power brought suit in the Western District of Texas alleging that Monolithic infringed Bel Power’s patents by selling power modules used in electronic devices. Monolithic had four remote employees working from home in the district. Monolithic moved to dismiss or transfer to the Northern District of California, arguing that because it was a Delaware corporation without property in the district, venue was not proper under § 1400(b). The district court denied both requests, finding that Monolithic maintained a business presence in the district as contemplated by § 1400(b) by soliciting employment in the district and providing employees with equipment used at or distributed from their homes as part of their employment responsibilities.

In denying the motion to transfer, the district court found that Monolithic had not established that the Northern District of California was clearly more convenient. Monolithic filed for mandamus seeking to overturn either ruling.

The Federal Circuit denied relief. With regard to venue, the Court reasoned that “the district court’s ruling does not involve the type of broad, fundamental, and recurring legal question or usurpation of judicial power that might warrant immediate mandamus review.” Instead, the Court credited the factual findings regarding the amount of equipment Monolithic provided to one of its employees in the district for “the sole purpose” of allowing him “to conduct testing and validation as part of his job,” and ruled that post-judgment appeal would be an adequate alternative means for attaining relief. On the issue of transfer (reviewed under regional circuit law), the Court denied for failure to establish a clear abuse of discretion, noting that this “is not a case in which there is only one correct outcome.”

Judge Lourie dissented, arguing that “[m]ost basically, Monolithic lacks a regular and established place of business in the Western District of Texas, as the statute requires in order for it to be sued there.” In his view, “we should not stand back and let the requirements of the statute be eroded by the details of what an employee stores in his or her home.” He noted that judicial efficiency counsels against allowing cases to be tried in venues not permitted by the statute only to be retried in a proper venue. Judge Lourie reasoned that the circumstances relied on by the district court, including job advertisement and storage of product and equipment in the venue, were not meaningfully different from those of Celgene v. Mylan Pharms (Fed. Cir, 2021), where venue was deemed improper. He noted that “[t]he [...]

CAFC Pulls Final Loose Thread in Nike-Adidas Patent Row

By on Sep 22, 2022
Posted In

Issuing a third and final decision, the US Court of Appeals for the Federal Circuit affirmed a Patent Trial & Appeal Board (Board) decision invalidating the last remaining claim of a Nike footwear textile patent. Nike, Inc. v. Adidas AG, Case No. 21-1903 (Fed. Cir. Sept. 1, 2022) (Prost, Chen, Stoll, JJ.) (non-precedential)

Adidas filed for inter partes review of a patent owned by Nike relating to a knitted shoe upper. After lengthy litigation, including two prior appeals to the Federal Circuit, all claims of the Nike patent were invalidated except for one substitute claim. In its second appeal, Nike successfully argued that the Board did not provide Nike an opportunity to respond to a patentability issue raised sua sponte by the Board, which included reference to a knitting textbook. On remand from the second appeal, the parties were given the opportunity to brief the Board on this new reference and argue which party bears the burden of persuasion for the patentability issue raised sua sponte by the Board.

On the merits, the Board determined that the knitting textbook did teach the disputed limitation, agreeing with adidas that a skilled artisan would have understood the textbook to teach the contested limitation, and that there was adequate reason to combine the textbook’s teachings with those of the other prior art references. The Board also concluded that the burden of persuasion must fall on the Board itself when it raised the patentability issue sua sponte. Nike appealed, arguing that the Board effectively placed the burden of persuasion on Nike.

The Federal Circuit first addressed the burden of persuasion as it relates to the grounds first raised by the Board. The Court found that the Board juxtaposed its arguments with adidas’s and that they both relied on the same disclosures and arguments. Because the Board and adidas’s arguments mirrored each other, the Court found it unnecessary to determine whether the petitioner or the Board bears the burden of persuasion. The Court also rejected Nike’s argument that the Board effectively shifted the burden to Nike by stating in its opinion that Nike’s arguments were “unpersuasive” and “inadequate.” The Court cited to its 2016 holding in In re Magnum Oil Tools International, in which it explained that the Board’s language is not the concern but rather the actual placement of the burden of persuasion. The Court found that both the Board and adidas met the burden, and that the burden was not shifted to Nike.

Turning to the Board’s obviousness determinations, the Federal Circuit rejected all of Nike’s arguments. First, Nike argued that the knitting textbook did not teach the claimed method of creating apertures in the fabric by omitting stitches. The Court found that the Board relied on specific disclosures in the reference describing the use of empty needles to product “loop displacement.” Nike also argued that there was no motivation to combine the textbook reference with the other two references and that the Board could not rely on “common sense” [...]

Arthrex, Still Without Director Review, Gets Constitutional Review from Patent Commissioner

By on Jun 2, 2022
Posted In

A panel of the US Court of Appeals for the Federal Circuit considered whether the Patent Commissioner, on assuming the role of the US Patent & Trademark Office (PTO) Director, can constitutionally evaluate the rehearing of Patent Trial & Appeal Board (Board) inter partes review (IPR) decisions. The panel concluded that neither Appointments Clause jurisprudence nor the Federal Vacancies Reform Act (FVRA) impeded the Commissioner from exercising the PTO Director’s authority. Arthrex, Inc. v. Smith & Nephew, Inc. et al., Case No. 18-2140 (Fed. Cir., May 27, 2022) (Moore, C.J.; Reyna, Chen, JJ.)

Approximately one year ago, Arthrex succeeded in the Supreme Court of the United States on its argument that the Appointments Clause of the Constitution was violated unless a presidentially appointed and Senate-confirmed officer (such as the PTO Director) could review the Board’s final IPR decisions. (United States v. Arthrex, Inc.) The case returned to the PTO on remand. At the time, the position of PTO Director was vacant, and there was no acting director. Pursuant to the FVRA, the Commissioner of Patents (a position filled by the Secretary of Commerce) exercised the PTO Director’s authority to review Board decisions and ultimately rejected Arthrex’s challenge to the Board’s unpatentability determination. Arthrex appealed.

Arthrex contended that the Commissioner could not constitutionally exercise the PTO Director’s IPR review authority without running afoul of the Appointments Clause, that the FVRA barred the Commissioner’s exercise of authority and that the Commissioner violated separation of powers. Arthrex also challenged the ruling on the merits. None of these challenges were successful.

First, the Federal Circuit concluded that Arthrex reinforced long-settled Supreme Court precedent that an inferior officer could exercise a principal officer’s authority constitutionally on a temporary basis without violating the Appointments Clause. Here, the Court concluded that the Commissioner’s exercise of the PTO Director’s IPR review authority until a new director was installed presented no problem.

Second, the FVRA provides a statutory framework for the exercise of a principal officer’s duties under certain circumstances, which, if the law applied, would not have allowed the Commissioner to review IPR decisions. However, the Federal Circuit explained that the FVRA narrowly governs only those duties of an officer that are statutorily non-delegable (i.e., which US Congress has required to be exercised personally by the officer). According to the Court, such provisions did not apply here because nothing demonstrated that the PTO Director’s newly created authority to review IPR decisions was non-delegable.

Third, the Federal Circuit rejected Arthrex’s argument that the Commissioner’s service as the PTO Director violated the line of precedent that limits Congress’ ability to circumscribe the president’s removal authority for superior officers. Arthrex contended that the Commissioner, a non-superior officer, could be removed only for “misconduct or nonsatisfactory performance” and therefore could not fill the role of the PTO Director. The panel disagreed, explaining that the president could name an acting director “with the stroke of a pen,” and so the limits on removing the Commissioner from his role as Commissioner [...]

Only under Rare Circumstances Can the Patent Trial & Appeal Board Find Proposed Substitute Claims Unpatentable on Its Own

By on Mar 31, 2022
Posted In

The US Court of Appeals for the Federal Circuit addressed, for the first time, the issue of when the Patent Trial & Appeal Board (Board) may raise a ground of unpatentability that was not advanced by a petitioner in relation to proposed substitute claims. The Court upheld the standard defining the “rare circumstances” in which such a ruling is proper while questioning the Board’s reasoning and application of the standard. Hunting Titan, Inc. v. DynaEnergetics Europe GMBH, Case Nos. 20-2163; -2191 (Fed. Cir. Mar. 24, 2022) (Prost, C.J., Reyna, Hughes, JJ.) (Prost, C.J., concurring).

Hunting Titan challenged DynaEnergetics’ patent in an inter partes review (IPR) based on anticipation and obviousness grounds. The Board found all the original claims of the patent unpatentable as anticipated. DynaEnergetics moved to amend to add proposed substitute claims. Hunting Titan opposed the motion to amend but advanced only obviousness grounds against the proposed substitute claims. The Board determined sua sponte that the proposed substitute claims were unpatentable as anticipated and, therefore, denied the motion to amend. DynaEnergetics requested rehearing, and the Precedential Opinion Panel (POP) reversed the Board’s denial of the motion to amend and determined that Hunting Titan did not prove that the proposed substitute claims were unpatentable.

The POP decided that “only under rare circumstances” should the Board sua sponte raise a ground for unpatentability not advanced by the petitioner in relation to proposed substitute claims. The rare circumstances include only two situations:

  1. When the petitioner is not involved in the motion to amend, such as when a petitioner chooses not to oppose the motion or ceases to participate in the proceeding altogether
  2. When evidence of unpatentability is readily identifiable and persuasive, such as if the substitute claims are unpatentable for the same reasons as the original claims.

The POP stated that in most circumstances, it is best to rely on the adversarial system and expect the petitioner to raise the unpatentability grounds for consideration.

The Federal Circuit upheld the POP’s standard for when the Board may sua sponte find proposed substitute claims unpatentable but also found the POP’s reasoning “problematic” because it placed too much emphasis on the adversarial system. The Court noted that Board proceedings, such as IPRs, are fundamentally a review of an earlier administrative proceeding, as opposed to civil litigation, The POP’s rationale was based on the public interest being served by an adversarial system rather than on the public interest being served by maintaining integrity of the patent system.

The Federal Circuit also questioned the POP’s application of its new standard to the case at hand, noting that the readily identifiable evidence exception should have been applied when the Board found the proposed substitute claims unpatentable for the same reasons it found the original claims to be unpatentable.

In her concurring opinion, Chief Judge Prost noted that “[i]t makes little sense to limit the [Board], in its role within the agency responsible for issuing patents, to the petitioner’s arguments.” Instead, “the Board must determine whether the [...]

Federal Circuit Reverses Judge Stark Decision, Finds Computer Network Patent Eligible

By on Dec 9, 2021
Posted In

The US Court of Appeals for the Federal Circuit concluded that a representative claim was directed to a patent-eligible improvement to computer functionality, and therefore reversed a decision authored by Judge Leonard P. Stark as a sitting judge in the US District Court for the District of Delaware. Mentone Solutions LLC v. Digi International Inc., Case Nos. 21-1202, -1203 (Fed. Cir. Nov. 15, 2021) (Moore, C.J.) (nonprecedential).

Mentone Solutions sued Digi International for infringement of Mentone’s patent directed to an improvement in dynamic resource allocation in a GPRS cellular network utilizing shifted uplink status flags (USF). Digi moved to dismiss under Fed. R. Civ. P. 12(b)(6), arguing that the patent claims were not patent eligible under 35 U.S.C. § 101. The district court granted the motion to dismiss, holding that the representative claim was patent ineligible for being “directed to the abstract idea of receiving a USF and transmitting data during the appropriate timeslots.” Mentone appealed.

The Federal Circuit began its analysis with a detailed explanation of the claimed technology and how its use of a “shifted USF” improved the normal operation of the communication system, noting that the shifted USF specifically allowed a mobile station to access previously restricted multi-slot configurations.

Reviewing the district court’s § 101 eligibility determination de novo, the Federal Circuit applied the Supreme Court’s two-step Alice framework, first determining whether the representative claim was directed to an abstract idea. The Court explained that in cases involving software, step one often turns on whether the claim focuses on specific asserted improvements in the computer’s capabilities rather than on an abstract idea which merely invoked a computer as a tool.

The Federal Circuit compared the claim in issue to those at issue in Packet Intelligence v. NetScout Sys., in which the Court found that the challenged claims were directed to a problem unique to computer networks and that the patent specification provided details on how the solution to the network problem was achieved. In Packet Intelligence, the Court looked to the patent specification to inform its understanding of the claimed invention and found that the specification made clear that the claimed invention solved a challenge unique to computers.

Similarly, in this case, the Federal Circuit explained that the representative claim did not recite generalized steps to be performed on a computer but rather a particular method of breaking the timing between the downlink USF and the subsequent uplink transmission. The Court noted that the term “shifted USF” was coined by the inventor, and that the specification and figures informed the Court’s understanding of the term, the claimed invention, the technical solution and how the elements of the claim work together to provide the solution. The Court concluded that the claimed invention solved a challenge unique to computer networks and was directed to patent-eligible improvements in computer functionality.

The Federal Circuit rejected the district court’s characterization of the claim as directed to the abstract idea of “receiving a USF and transmitting data during the appropriate [...]

Bascom Cannot Save Your Claims if Your Own Patent Says You Used Known Technology

By on Sep 9, 2021

The US Court of Appeals for the Federal Circuit affirmed a district court determination that claims of several patents were patent ineligible under 35 U.S.C. § 101 because they did not recite an innovation with sufficient specificity to constitute an improvement to computer functionality. Universal Secure Registry LLC v. Apple Inc., Case No. 20-2044 (Fed. Cir. Aug. 26, 2021) (Stoll, J.)

Universal Secure Registry (USR) sued Apple, Visa and Visa U.S.A. (collectively, Apple), asserting four patents directed to securing electronic payment transactions, which USR alleged allowed for making credit card transactions “without a magnetic-stripe reader and with a high degree of security” (e.g., allegedly Apple Pay or Visa Checkout). Apple moved to dismiss the complaint under Fed. R. Civ. Pro. 12(b)(6), arguing that the asserted patents claimed patent-ineligible subject matter under 35 U.S.C. § 101. The Delaware magistrate judge, quoting Visual Memory v. NVIDIA (Fed. Cir. 2017), determined that all the representative claims were directed to a non-abstract idea because “the plain focus of the claims is on an improvement to computer functionality itself, not on economic or other tasks for which a computer is used in its ordinary capacity.”

The district court judge disagreed, concluding that the representative claims failed at both Alice steps, and granted Apple’s motion to dismiss. The district court found that the claimed invention was directed to the abstract idea of “the secure verification of a person’s identity,” and that the patents did not disclose an inventive concept—including an improvement in computer functionality—that transformed the abstract idea into a patent-eligible application. USR appealed.

In assessing the claims under the Alice two-part test, the Federal Circuit noted that in cases involving authentication technology, patent eligibility often turns on whether the claims provide sufficient specificity to constitute an improvement to computer functionality itself. For example, in its 2017 decision in Secured Mail Solutions v. Universal Wilde, the Court (at Alice step one), held that claims directed to using a conventional marking barcode on the outside of a mail object to communicate authentication information were abstract because they were not directed to specific details of the barcode, how it was processed or generated or how it was different from long-standing identification practices. Similarly, in its 2020 decision in Prism Technologies v. T-Mobile, where the claims broadly recited “receiving” identity data of a client computer, “authenticating” the identity of the data, “authorizing” the client computer and “permitting access” to the client computer, the Court held at Alice step one that the claims were directed to the abstract idea of “providing restricted access to resources,” not to a “concrete, specific solution.” At step two, the Court determined that the asserted claims recited conventional generic computer components employed in a customary manner such that they were insufficient to transform the abstract idea into a patent-eligible invention.

The claims in issue fared similarly. The district court held that the representative claim was not materially different from the Prism claims, and the Federal Circuit agreed. Although the [...]

Diehr Alice, Yu are Superimposing Novelty onto Patent Eligibility. Love, Newman.

By on Jun 24, 2021
Posted In

The US Court of Appeals for the Federal Circuit affirmed the district court’s grant of a Rule 12(b)(6) motion to dismiss on the basis that, under the two-step Alice analysis, the patent claims—directed to a digital camera—were directed to ineligible subject matter under 35 U.S.C. § 101. Yu, et al. v. Apple Inc., et al., Case Nos. 20-1760; -1803 (Fed. Cir. June 11, 2021) (Prost, J.) (Newman, J., dissenting)

The patent claim under consideration recited an “improved digital camera” that has two lenses, two image sensors, an analog-to-digital converter, a memory and a digital image processor for “producing a resultant digital image from said first digital image enhanced with said second digital image.” Yu conceded that “the idea and practice of using multiple pictures to enhance each other has been known by photographers for over a century” and that the components recited in the claim “are themselves generic and conventional.”

Applying the Supreme Court’s two-step Alice v. CLS Bank test for determining patent eligible subject matter, the Federal Circuit determined at step one that the claim was “directed to the abstract idea of taking two pictures . . . and using one picture to enhance the other in some way.” At step two, the Court held that the claim failed to otherwise define a patent eligible invention because the digital camera “is recited at a high level of generality and merely invokes well-understood, routine, conventional components to apply the abstract idea of [using one picture to enhance the other in some way].” The Court rejected Yu’s attempts to use portions of the patent’s specification to support eligibility, explaining that the eligibility analysis is limited to the literal recitations of the asserted claims.

Then, along came Judge Pauline Newman. With a chainsaw.

In dissent, Judge Newman argued that the majority was improperly enlarging the § 101 analysis to include other “substantive requirements of patentability.” Judge Newman emphasized (twice) that the claim literally recited an electromechanical camera, not an abstract idea. In her view, the camera recited in the claim met the requirements of § 101 as a new and useful machine, without regard to whether the claimed camera also met the novelty requirements of §§ 102 and 103. Referring to the Supreme Court’s 1981 holding in Diamond v. Diehr, Judge Newman wrote that “[i]n contravention of [Diehr‘s] explicit distinction between Section 101 and Section 102, the majority now holds that the [claimed] camera is an abstract idea because the camera’s components were well-known and conventional and perform only their basic functions.” Judge Newman further proclaimed that “the principle that the majority today invokes was long ago discarded.”

Judge Newman also admonished the majority for the destabilizing effects that similar holdings have already had on US patent policy. She noted that “[i]n the current state of Section 101 jurisprudence, inconsistency and unpredictability of adjudication have destabilized technologic development in important fields of commerce,” and that “[t]he fresh uncertainties engendered by the majority’s revision of Section 101 are contrary to the statute and [...]
