Branding Function Patent Yet Another 1[01] to Bite the Dust

by | Apr 20, 2023 |

Addressing the patentability of claims directed to digital image branding functions, the US Court of Appeals for the Federal Circuit affirmed a district court’s determination that claims across three related patents were invalid under 35 U.S.C. § 101 for lacking patent-eligible subject matter. Sanderling Mgmt. Ltd. v. Snap Inc., Case No. 21-2173 (Fed. Cir. Apr. 12, 2023) (Chen, Cunningham, Stark, JJ.)

Sanderling owns three patents, each titled “Dynamic Promotional Layout Management and Distribution Rules.”  The three patents share a common specification and are generally directed to a method using distribution rules to load digital imaging branding functions to users when certain conditions are met. The specification explains that a distribution rule is “a rule used in determining how to target a group of end users, for instance, a rule that determines that only a group of end users having certain characteristics and/or match a certain requirement.”

Sanderling asserted each of the three patents against Snap in the Northern District of Illinois. Snap moved to transfer venue to the Central District of California and to dismiss the case under Fed. R. Civ. P. 12(b)(6) for failure to state a claim based on the allegation that the asserted patents’ claimed ineligible subject matter under § 101. After the case was transferred, the Central District of California found the claims patent ineligible and granted Snap’s motion to dismiss. Sanderling appealed.

The Federal Circuit reviewed the decision by engaging in the two-step Alice framework for subject matter eligibility. Under step one, the Court determined that the claims were directed to the abstract idea of providing information—in this case, a processing function—based on meeting a condition (e.g., matching a GPS location indication with a geographic location). The Court explained that for computer-related inventions, the relevant question is whether the claims are directed to an improvement to computer functionality or to an abstract idea. The Court found that the claims in issue were not directed to an improvement in computer functionality, but instead to the use of computers as a tool—specifically, a tool to identify when a condition is met and then to distribute information based on satisfaction of that condition.

Even if directed to an abstract idea, patent claims may still be eligible under step two of the Alice framework if there are additional features that constitute an inventive concept. The Federal Circuit, however, found that the claims failed this step also. The Court explained that if a claim’s only inventive concept is the application of an abstract idea using conventional and well-understood techniques, the claim has not been transformed into a patent-eligible application of an abstract idea. The distribution rule of the asserted claims was just that: the application of the abstract idea using common computer components. Accordingly, the Court affirmed the district court’s decision that the patent claims were invalid under § 101.

Practice Note: On appeal, Sanderling argued that the district court erred at step one of the Alice analyses by failing to construe certain claim terms that were allegedly crucial to the determination. [...]

Context Is Key in Claim Construction

by | Apr 20, 2023 |

The US Court of Appeals for the Federal Circuit reiterated that intrinsic evidence trumps extrinsic evidence in determining the meaning of claim terms. Sequoia Technology, LLC v. Dell, Inc. et al., Case Nos. 21-2263; -2264; -2265; -2266 (Fed. Cir. Apr. 12, 2023) (Stoll, Lourie, Dyk, JJ.)

Sequoia Technology owns a patent directed to data storage methods involving storing the same data across multiple physical disk drives to make up a virtual disk drive. Sequoia asserted the patent against several companies, all based on a product sold by Red Hat. During litigation, the parties disputed the construction of the terms “computer-readable recording medium,” “disk partition” and “logical volume.” Related to the latter two claim construction issues, the parties construed the term “used or not used” in the context of an extent’s usage in an “extent allocation table.”

The district court adopted Red Hat’s construction of “computer-readable recording medium” to include transitory media (i.e., signals or waves). The district court found no clear language in the specification that excluded transitory media and found Red Hat’s extrinsic evidence to be persuasive, “particularly given the lack of any substantive rebuttal from Sequoia’s expert.” For “disk partition” and “logical volume,” the district court agreed with Red Hat and construed “disk partition” to mean a “section of a disk that is a minimum unit of a logical volume” and “logical volume” to mean an “extensible union of more than one disk partition, the size of which is resized in disk partition units.” These constructions require that a logical volume is constructed by whole disk partitions, not subparts of disk partitions such as extents. The district court also construed the phrase “used or not used” in the limitation “extent allocation table for indicating whether each extent in the disk partition is used or not used,” adopting Red Hat’s construction that “used or not used” means that an extent “is or is not storing information.”

Following claim construction, the parties stipulated that under the district court’s claim construction of “logical volume” and “disk partition,” the accused products did not infringe the asserted claims. The parties also stipulated that under the district court’s construction of “computer-readable recording medium,” certain claims were subject matter ineligible under 35 U.S.C. § 101 as including transitory media. Sequoia appealed.

The Federal Circuit concluded that the district court erred in construing “computer-readable recording medium.” Starting with the claim language, the Court noted that the claim recited a “computer-readable recording medium storing instructions” and not simply a “computer-readable medium.” The Court reasoned that an ordinarily skilled artisan would understand transitory signals to be incompatible with the claimed invention because such fleeting signals would not persist for sufficient time to store instructions. Turning to the specification, the Court explained that although the specification did use open-ended “including” language to describe a computer-readable medium, the relevant portion of the specification defined computer-readable media as “including compact disc read only memory (CDROM), random access memory (RAM), floppy disk, hard disk, and magneto-optical disk,” all of which are non-transient [...]

The Alice Eligibility Two-Step Dance Continues

by | Mar 2, 2023 |

The US Court of Appeals for the Federal Circuit affirmed a district court’s dismissal of a Fed. R. Civ. P. 12(b)(6) motion, holding that patent claims directed to abstract ideas and lacking inventive steps that transform abstract ideas into patent-eligible inventions fail the Alice two-step test and are not patent eligible under 35 U.S.C. § 101. Hawk Tech. Sys., LLC v. Castle Retail, LLC, Case No. 22-1222 (Fed. Cir. Feb. 17, 2023) (Reyna, Hughes, Cunningham, JJ.)

35 U.S.C. § 101 states that laws of nature, natural phenomena and abstract ideas are not patentable. The Supreme Court of the United States in Alice v. CLS Bank Int’l (2014) articulated a two-step test for examining patent eligibility: a patent claim falls outside § 101 if it is directed to a patent-ineligible concept such as an abstract idea and lacks elements sufficient to transform the claim into a patent-eligible application.

Hawk Technology sued Castle Retail alleging infringement of its patent directed to security surveillance video operations in Castle Retail’s grocery stores. The patent relates to a method of viewing multiple simultaneously displayed and stored video images on a remote viewing device of a video surveillance system using result-based functional language. Castle Retail moved to dismiss on the basis that the claims were not patent eligible under § 101. After conducting a technology briefing, the district court granted the motion. The district court ruled that the claims were abstract because surveillance monitoring is a common business practice and the claims recited little more than taking video surveillance and digitizing it for display and storage in a conventional computer system, and the claims did not limit the abstract idea to a new technological improvement in video storage/display that could transform the abstract idea into a patent-eligible invention. Hawk Technology appealed.

The Federal Circuit, reviewing de novo, affirmed. Addressing Alice step one, the Court found that the patent’s required functional results of receiving/digitizing video images, converting images to selected format and storing/displaying/transmitting the images were similar to claims that the Court previously ruled as abstract. The results-oriented claim language failed to concretely recite how the claimed invention improved the functionality of video surveillance systems and was therefore abstract. Regarding Alice step two, the Court analyzed the claim elements, both individually and as an ordered combination in light of the specification, for transformative elements. The Court explained that although the claims recited the purported inventive solution and referenced specific tools/parameters, they neither showed how monitoring and storage was improved nor required anything other than off-the-shelf, conventional computer, network and display technology for gathering, sending and presenting the specified information.

Procedurally, the Federal Circuit found that the motion to dismiss was not decided prematurely because the technology briefing was purely a procedural step conducted in each patent case and there was no evidence that the district court’s decision hinged on new facts constituting matters beyond the pleadings. Hawk had argued that because the district court considered Castle’s testimony and evidence, it was required to convert the [...]

Tag, You’re It: Sanctions Award Must Reflect Violative Conduct

by | Dec 22, 2022 |

The US Court of Appeals for the Federal Circuit determined that an accused infringer was entitled to a new trial relating to validity issues but still faced sanctions for its continuous disregard of its discovery obligations. ADASA Inc. v. Avery Dennison Corp., Case No. 22-1092 (Fed. Cir. Dec. 16, 2022) (Moore, Hughes, Stark, JJ.)

ADASA owns a patent relating to methods and systems for commissioning radio-frequency identification (RFID) transponders. ADASA sued Avery Dennison for patent infringement, alleging that its manufacture and sale of certain RFID tags infringed ADASA’s patent. Both parties sought summary judgment following discovery. Avery Dennison asserted that the patent was ineligible for patent protection under 35 U.S.C. § 101, and ADASA argued that the asserted claims were not anticipated or obvious based on the book RFID for Dummies. The district court granted ADASA’s motion on validity and denied Avery Dennison’s motion for patent ineligibility. Prior to trial, ADASA moved in limine to exclude Avery Dennison’s damages expert’s testimony related to certain licenses, and the district court granted the motion.

At trial, ADASA entered licenses into evidence as part of its damages case and alleged that they reflected lump-sum agreements to practice the asserted patent. The district court declined to include a jury instruction on lump-sum damages and a lump-sum option on the verdict form, observing that Avery Dennison’s expert had not offered a lump-sum damages opinion and concluding that the licenses alone were insufficient for the jury to award lump-sum damages. The jury returned an infringement verdict and awarded ADASA a running royalty of $0.0045 per infringing RFID tag, which resulted in an award of $26.6 million.

In its post-trial motions, Avery Dennison moved for a new trial, arguing it was reversible error for the district court to exclude its damages expert’s testimony and to decline to provide a jury instruction for a lump-sum damages award. Before the district court ruled on its motion, Avery Dennison revealed to ADASA that it had discovered additional previously undisclosed RFID tags in its databases. A subsequent investigation determined that the number of undisclosed tags was more than two billion. Avery Dennison agreed to pay an additional $9.5 million in damages, which corresponded to the royalty rate determined by the jury. ADASA subsequently moved for sanctions. The district court award $20 million in sanctions after finding that Avery Dennison had engaged in protracted discovery failures and a continuous disregard for the seriousness of the litigation and its expected obligations. The sanctions award corresponded to a $0.0025 per-tag rate applied to both the adjudicated and late-disclosed tags. Avery Dennison appealed.

Avery Dennison challenged the district court’s summary judgment rulings, its denial of a new trial and its imposition of sanctions. The Federal Circuit affirmed the district court’s patent eligibility determination, finding that the patent “is directed to a specific, hardware-based RFID serial number data structure designed to enable technological improvements to the commissioning process,” which “is not a mere mental process,” and concluded that the claim was directed to patent-eligible subject matter.

Does Not Compute: Faster Processes Aren’t Enough for Subject Matter Eligibility

by | Oct 27, 2022 |

In yet another opinion addressing subject matter eligibility and application of the Supreme Court’s Alice decision, the US Court of Appeals for the Federal Circuit found claims directed to graphical displays and user interfaces subject matter ineligible as directed to abstract ideas. IBM v. Zillow Group, Inc., Case No. 21-2350 (Fed. Cir. Oct. 13, 2022) (Reyna, Hughes, Stoll, JJ.) (Stoll, J., dissenting in part).

IBM sued Zillow for allegedly infringing several patents related to graphical display technology. The district court granted Zillow’s motion for judgment on the pleadings that sought a ruling that two of the asserted patents claimed patent-ineligible subject matter under 35 U.S.C. § 101. IBM appealed.

On appeal, the Federal Circuit applied the Alice two-step analysis to determine whether the claims at issue were directed to a patent-ineligible concept, such as an abstract idea, and if so, whether additional claim elements (considering each element both individually and as an ordered combination) transformed the nature of the claim into a patent-eligible application. As discussed in the Supreme Court Alice and Mayo decisions, the second step is “a search for an ‘inventive concept’—i.e., an element or combination of elements that is ‘sufficient to ensure that the patent in practice amounts to significantly more than a patent upon the [ineligible concept] itself.’”

The representative claim of the first patent was directed to a method for coordinated geospatial and list-based mapping, and the method steps recited viewing elements having “geospatial characteristics” in a given viewing area of a map space and displaying a list of the elements in that space. The user then draws a selected area within the map space, having elements that may be inside or outside of the selected area. The elements having the geospatial characteristics within the selection area are selected and those outside the selected area are deselected. The map display and the list are then synchronized and concurrently updated to reflect what has been selected and deselected.

The district court concluded that “the patent was directed to the abstract idea of responding to a user’s selection of a portion of a displayed map by simultaneously updating the map and a co-displayed list of items on the map,” reasoning that the claimed method could be performed manually, for example, by putting a transparent overlay on a printed map, drawing on it with a marker, and then blocking off the “unselected area” of the map and corresponding list items with opaque paper cut to appropriate sizes. To choose a different “selection area,” the user would erase the prior markings, remove the paper and start over. The district court noted that “alterations to hardcopy materials were made or auditioned in this manner” long before computers, and concluded that “[t]he [] patent merely contemplates automation using a computer.”

The Federal Circuit agreed that the claims failed to recite any inventive technology for improving computers as tools and were instead directed to an abstract idea for which computers were invoked merely to limit and coordinate the display of information based [...]

The Name of the Game Is the Claims, Even if Specification Is Shared

by | Oct 20, 2022 |

Once again addressing the application of Alice, the US Court of Appeals for the Federal Circuit partially reversed a district court’s dismissal of several patents as subject matter ineligible for error in analyzing their claims together because of a shared specification despite different claim features. Weisner v. Google LLC, Case No. 021-2228 (Fed. Cir. Oct. 13, 2022) (Reyna, Hughes, Stoll, JJ.) (Hughes, J., dissenting in part)

Sholem Weisner sued Google for infringement of four related patents describing ways to “digitally record a person’s physical activities” and use the digital record. The patents’ common specification described how individuals and businesses can sign up for a system to exchange information (e.g., “a URL or an electronic business card”), and as they encounter people or businesses that they want recorded in their “leg history,” the URLs or business cards are recorded along with the time and place of the encounters. Google moved to dismiss the suit under Fed. R. Civ. P. 12(b)(6), arguing that the patent claims were directed to ineligible subject matter under 35 U.S.C. § 101, and that Weisner had failed to meet the minimum threshold for plausibly pleading his claim of patent infringement under the Twombly and Iqbal standards (Twiqbal). The district court agreed and granted dismissal under Twiqbal. After holding a hearing on patent ineligibility, the district court also granted dismissal under § 101 but granted Weisner leave to amend his complaint. In his amended complaint, Weisner added infringement allegations, allegations related to patent eligibility and an “Invention Background and System Details Explained” section. Google again moved to dismiss the amended complaint based on both § 101 and Twiqbal, which the district court granted. Weisner timely appealed.

The Federal Circuit applied the Alice two-step analysis to determine whether the claims at issue were directed to a patent-ineligible concept, such as an abstract idea, and if they were, whether the elements of each claim, both individually and as an ordered combination, transformed the nature of the claim into a patent-eligible application. As discussed in the Supreme Court cases Alice and Mayo, the second step is “a search for an ‘inventive concept’—i.e., an element or combination of elements that is ‘sufficient to ensure that the patent in practice amounts to significantly more than a patent upon the [ineligible concept] itself.’”

There were four asserted patents in issue. For the first two patents, Weisner attempted to argue that the claims improved “the functioning of the computer itself” or “an existing technology process” by “[1] automatically recording physical interactions and [2] limiting what is recorded to only specific types of interactions that are pre-approved and agreed to by an individual member and a vendor member.” However, the Federal Circuit was unconvinced that this was the type of improvement found in Enfish to bring claims into the realm of inventiveness. Instead, the Court agreed with the district court that, consistent with past precedent, this was no different than travel logs, diaries, journals or calendars used to keep records of a person’s location, and that [...]

New Patent Eligibility Bill May Impact What Subject Matter Is Patentable

by | Aug 18, 2022 |

On August 2, 2022, Senator Thom Tillis (R-NC) introduced the Patent Eligibility Restoration Act of 2022. Senator Tillis’s bill addresses patent subject matter eligibility by modifying 35 U.S.C. § 101 to mitigate areas in which it has been considered problematic in view of recent judicial decisions/exceptions construing it while retaining its core features. For some in the biotechnology space, “problematic” Supreme Court decisions have included May Collaborative Services (2012), Myriad Genetics (2013), Alice Corp. (2014) and their Federal Circuit progeny.

The core features for eligibility will remain in the statute as: “[w]hoever invents or discovers any useful process, machine, manufacture, or composition of matter, or any useful improvement thereof, may obtain a patent therefore.”

The bill provides express exceptions, including:

  • A mathematical formula, apart from useful invention or discovery
  • An unmodified human gene, as that gene exists in the human body
  • An unmodified natural material, as that material exists in nature.

However, the bill further states that genes or natural material that are “purified, enriched, or otherwise altered by human activity, or otherwise employed in a useful invention or discovery,” would not be considered unmodified and would be eligible for patents. One of the goals of the bill is to override case law that has made it  difficult to receive patents on diagnostics inventions and otherwise blurred the line between what inventions are considered abstract.

Processes that are excluded from eligibility under the bill include:

  • Nontechnological economic, financial, business, social, cultural or artistic processes
  • Mental processes performed solely in the human mind
  • Processes occurring in nature wholly independent of, and prior to, any human activity.

Under current law, the question of what constitutes a technological solution that would render an otherwise abstract idea patent eligible is a hotly contested one often determined on a case-by-case basis. The European Patent Convention’s eligibility exclusions include presentations of information and mathematical methods. However, if there is a technical use applied to those types of inventions, they are patent eligible.

The bill was reportedly drafted following three years of work by Senator Tillis’ team, including a series of US Senate hearings in 2019 with Senator Chris Coons (D-DE) and meetings with an array of industries. Updates will be posted to the IP Update blog as legislative developments warrant.

PTO Presentation Seeks to Clarify Subject Matter Eligibility Requirements

by | Aug 18, 2022 |

On August 9, 2022, the US Patent & Trademark Office (PTO) gave a public presentation, “Subject Matter Eligibility Under 35 U.S.C. § 101: USPTO Guidance and Policy.” During the presentation, the PTO indicated that its goal is to identify eligible subject matter and not reject patent applications under 35 U.S.C. § 101 where possible. However, subject matter eligibility must be determined in accordance with Supreme Court precedent as set forth in Bilski v. Kappos (2010); Mayo Collaborative Servs. v. Prometheus Labs, Inc. (2012); Association for Molecular Pathology v. Myriad Genetics, Inc. (2013); and Alice Corp. v. CLS Bank International (2014). The PTO presented several biotech examples demonstrating how subject matter ineligible claims could be redrafted to encompass eligible subject matter.

The PTO presented a detailed explanation of the two-step subject matter eligibility flowchart in MPEP § 2106 and emphasized the differences between the two prongs of Step 2A. The first prong is to evaluate whether the claim recites a judicially recognized exception to eligibility. If the claims do not recite an exception, they qualify as eligible subject matter. If the claims do recite a judicial exception, the analysis proceeds to the second prong of Step 2A, which is to evaluate whether the claims recite additional elements that integrate the exception into a practical application of the exception. If the claims do recite additional elements integrating the exception into a practical application of the exception, they qualify as eligible subject matter. If the claims do not do so, the analysis proceeds to Step 2B to determine whether the claims recite additional elements that amount to significantly more than the judicial exception.

While there is significant overlap between Step 2A prong two and Step 2B, the PTO noted that under Step 2A prong two, the additional elements may be well understood, routine, conventional activity, unlike in Step 2B. For example, if conventional steps were used to affect a particular treatment or prophylaxis for a disease or medical condition, or if conventional material was used in an unconventional application, the claims would be subject matter eligible.

The PTO warned against claiming methods as a series of mental processes, mere data gathering or steps that merely apply the judicial exception.

As noted, the PTO highlighted techniques for transforming subject matter ineligible claims into subject matter eligible claims. These techniques include reciting properties that naturally occurring compositions do not possess, showing that the claimed composition possesses properties not found in naturally occurring compositions, using a conventional material or conventional method in an unconventional application and specifying a particular treatment.

Practice Note: Readers may be interested in an IP Update Legislative Alert reporting on a bill introduced by Senator Tillis to amend §101, which can be found here.

Standard Techniques Applied in Standard Way to Observe Natural Phenomena? Not Patent Eligible

by | Jul 28, 2022 |

In what may be another blow to diagnostic patents, the US Court of Appeals for the Federal Circuit affirmed the patent ineligibility of claims that it held to be directed to detecting natural phenomena by conventional techniques. CareDx, Inc. v. Natera, Inc., Case No. 2022-1027 (Fed. Cir. July 18, 2022) (Lourie, Bryson, Hughes, JJ.)

CareDx is the exclusive licensee of three Stanford University patents directed to diagnosing or predicting organ transplant status by using methods to detect a donor’s cell-free DNA (cfDNA). When an organ transplant is rejected, the recipient’s body destroys the donor cells, releasing cfDNA from the donated organ’s dying cells into the blood. Detecting the naturally increased levels of donor cfDNA (due to the deteriorating organ condition) can be used to diagnose the likelihood of an organ transplant rejection.

The representative claims were summarized as having four steps for detecting a donor’s cfDNA in a transplant recipient:

  1. “Obtaining” or “providing” a “sample” from the recipient that contains cfDNA
  2. “Genotyping” the transplant donor and/or recipient to develop “polymorphism” or “SNP” “profiles”
  3. “Sequencing” the cfDNA from the sample using “multiplex” or “high-throughput” sequencing, or performing “digital PCR”
  4. “Determining” or “quantifying” the amount of donor cfDNA.

CareDx filed two lawsuits, one alleging that Natera’s kidney transplant rejection test infringed the patents, and another alleging that Eurofins Viracor’s various organ transplant rejection tests infringed one of the patents. Natera and Eurofins moved to dismiss the complaints for failing to state a claim because of a lack of patent-eligible subject matter under 35 U.S.C. § 101. The magistrate judge who reviewed the motions recommended that they be denied, finding that the claims were a “purportedly new, unconventional combination of steps” to detect natural phenomena. Although the recommendation was vacated with regard to Natera because the complaint was amended, the district court adopted the magistrate’s recommendation as to Eurofins with modified reasoning that the patent “specifications raise doubts about the patents’ validity” by suggesting that the steps were neither new nor unconventional. Still, the district court was wary of ruling prematurely and denied the motion so that the parties could conduct discovery to develop the record on what was considered conventional in the art.

Following expert discovery relating to § 101 eligibility, Natera and Eurofins moved for summary judgment on patent ineligibility. The district court denied summary judgment, citing a factual dispute as to the conventionality of the techniques for performing the claimed methods. Natera and Eurofins moved for certification of interlocutory appeals of the district court’s denial. After conferring with the parties, the district court agreed to reconsider its decision in view of case law raised in the certification motion. After reconsideration, the district court granted the summary judgment motions of ineligibility, finding that the asserted claims were directed to the detection of natural phenomena—specifically, the presence of donor cfDNA in a transplant recipient and the correlation between donor cfDNA and transplant rejection—and concluding that based on the specification’s many admissions, the claims recited only conventional techniques.

CareDx appealed, arguing [...]
