Patenting Web Advertising? Ask Alice, I Think She’ll Know

In a wide-ranging opinion, the US Court of Appeals for the Federal Circuit affirmed the district court’s grant of summary judgment of invalidity for lack of patent eligible subject matter under 35 U.S.C. § 101 with respect to claims directed to web-based advertising. Chewy, Inc. v. International Business Machines, Corp., Case No. 22-1756 (Fed. Cir. March 5, 2024) (Moore, Stoll, Cunningham, JJ.)

Chewy filed suit against International Business Machines (IBM) seeking a declaration that Chewy’s website did not infringe multiple patents related to web-based advertising. IBM responded by filing infringement counterclaims. After claim construction and discovery, the district court granted Chewy’s motions for summary judgment of invalidity for lack of patent eligible subject matter with regard to the asserted claims of one patent and noninfringement of the asserted claims of a second patent.

The claims of the first patent relate to providing a targeted advertisement from an “information repository” to a user based on the user’s internet search. In affirming the district court, the Federal Circuit first determined that, under Alice step 1, “[t]he claims broadly recite correlating advertisements with search results using a generic process.” The Court noted that the claims “merely recite the concept of identifying advertisements based on search results, without any specificity as to how this is accomplished,” and are directed to “the abstract idea of identifying advertisements based on search results.”

Turning to Alice step 2, the Federal Circuit found that the claims used a generic database and conventional processing steps, and “claimed use of a conventional repository for storing advertisements and associated search results in a well-known way.” Because “the claims recite the generic process for obtaining search results from a search query and using the search results to identify advertisements,” they failed under Alice step 2 and did not claim patent eligible subject matter under § 101.

Regarding the second asserted patent, the district court construed the claim term “selectively storing advertising objects at a store established at the reception system” as requiring the “advertising objects” to be “pre-fetched” and retrieved before the user requested a page on a website. Because it was undisputed that “Chewy retrieves advertisements in response to a user requesting a page” and not before, the district court ruled that Chewy’s website did not meet this claim limitation. Looking to the intrinsic claim construction evidence, the Federal Circuit held that the district court’s claim construction was amply supported by the specification and prosecution history and affirmed the district court’s grant of summary judgment of noninfringement. Of note, the Court explained that the specification made multiple references to pre-fetching as being part “of the present invention” and therefore limited the scope of the claims.

With respect to one asserted claim of the second patent, which did not include the limitation at issue, the district court found that Chewy’s website did not practice the limitation of “establishing characterizations for respective users based on the compiled data” because “the record undisputedly showed they deliver advertisements based on the page the user is currently viewing, [...]

Senate Holds Hearing on Legislative Initiative to Address Patent Eligibility

Seeking to undo the current jurisprudence “mess” on the issue of patent eligibility, the Senate Judiciary Committee’s Subcommittee on Intellectual Property heard testimony on January 23, 2024, on the Patent Eligibility Restoration Act (PERA) (text here). PERA seeks to address the uncertainty and unpredictable outcomes created by the 2014 Supreme Court of the United States decision in Alice Corp. Pty. v. CLS Bank Int’l.

PERA is the latest iteration of 35 USC § 101 patent eligibility reform that Senators Thom Tillis (R-NC) and Chris Coons (D-DE) have been introducing for years. Although the language has been tweaked over time, the bill’s purpose is to eliminate “[a]ll judicial exceptions to patent eligibility” and in their place codify several categories of inventions as unpatentable, such as mathematical formulas; processes that are substantially economic, financial, business, social, cultural or artistic; processes that are mental or purely natural; unmodified human genes; and unmodified natural materials.

The January 23 hearing featured eight witnesses, divided into two panels. The first panel included:

  • Andrei Iancu, former US Patent & Trademark Office (PTO) director
  • Richard Blaylock, testifying on behalf of Invitae Corporation
  • Courtenay Brinckerhoff, partner at Foley & Lardner
  • Phil Johnson, steering committee chair at the Coalition for 21st Century Patent Reform.

The second panel included:

  • The Honorable David Kappos, former PTO director
  • Adam Mossoff, professor at the Antonin Scalia Law School
  • Mark Deem, operating partner of Lightstone Ventures
  • David Jones, executive director of the High-Tech Inventors Alliance.

Harkening back to prior panels, the testimony was largely in favor of reform considering what many characterized as inaction by all other stakeholders. Senators and witnesses alike recognized that legislative reform is likely the only way to gain clarity on § 101 considering the Supreme Court’s failure to take up more than 100 certiorari petitions seeking review, many with the Solicitor General’s endorsement.

During the first panel, Blaylock testified that PERA would improperly provide patent eligibility to new uses of natural phenomena, such as genetic material, and therefore “would stifle innovation and harm patient care in the fields of diagnostic genetic testing and precision medicine.” Iancu testified in response that “all human invention is the manipulation of nature towards practical uses by humans on this planet . . . and it should be eligible for a patent.” Brinckerhoff’s testimony also opposed Blaylock’s view; she explained that considerable research and development is needed to develop new uses for isolated natural products and would be disincentivized without patent eligibility. Brinckerhoff highlighted an important theme at the hearing: “PERA would bring eligibility back in line with other countries” by permitting patents on methods of detecting new diagnostic markers, thus maintaining international competitiveness. Lastly, Johnson testified that “[j]ust because something is eligible doesn’t mean it’s patentable” and stressed the importance of using §§ 102, 203 and 112 as additional filters to determine patentability.

During the second panel, venture capitalist Deem testified that “the United States is failing many of our most innovative startups” because [...]

Struggling to Master the Alice Two-Step: Search Result Display Ineligible for Patent Protection

The US Court of Appeals for the Federal Circuit affirmed a district court’s dismissal of a lawsuit involving two software patents directed toward enhancements to search result displays, finding that both patents claimed subject matter that is ineligible under 35 U.S.C. § 101. IBM v. Zillow Group, Inc., Case No. 22-1861 (Fed. Cir. Jan. 9, 2024) (nonprecedential) (Prost, Hughes, JJ.) (Stoll, J., dissenting).

IBM sued Zillow for infringing five patents. Claims from two of the patents were dismissed. For the remaining three patents, Zillow filed a motion to dismiss, arguing that all three patents were ineligible under § 101. The district court granted Zillow’s motion to dismiss, finding the asserted claims ineligible. IBM appealed.

Only two of the patents were subject to the appeal. The first patent was directed to a graphical user interface that improves search and selection based on user input to produce better results, and the second patent was directed to improvements in how to display search results to users.

IBM raised two arguments on appeal:

  • The district court erred in dismissing both patents, because the complaint and IBM’s inventor declaration were enough to show patent eligibility and—at minimum—survive the pleading stage.
  • The district court failed to resolve a claim construction dispute over a term in the second patent.

The Federal Circuit began by providing a primer on the Alice two-step process for evaluating patent eligibility. For step one, courts must “determine whether a patent claim is directed to an unpatentable law of nature, natural phenomena, or abstract idea.” When the patent involves software, claims are ineligible where they merely describe a process or system that uses a computer as a tool applied to an otherwise abstract idea. For step two, courts must analyze whether the claims simply describe an abstract method. If the claims instead go further and transform an otherwise abstract idea into something new via an “inventive concept,” then the subject matter may be patentable.

Turning to the appeal, the Federal Circuit first addressed whether IBM’s complaint and inventor declaration should have been enough to establish subject matter eligibility at the pleading stage for either patent. Applying the Alice two-step test, the Court found that they were not and upheld the district court’s dismissal.

For the first patent directed to a graphical user interface, the Federal Circuit agreed with the district court’s conclusion that the patent had three clear indicia of abstractness. First, the process could be done with pen and paper. Second, the claim language was result-oriented. Third, the patent focused on intangible information. The Court also found that the claims did “not disclose any technical improvement” to computer software. Thus, the claims failed at Alice step one. The Court found that IBM fared no better at step two, explaining that IBM’s argument for an inventive process hinged on the inventor declaration, which made no reference to the patent’s actual claim language. The Court explained that “[s]imply including allegations of inventiveness in a complaint, detached from what is claimed or discussed in [...]

Same Applicant, Similar Claims Support Obviousness-Type Double Patenting Rejection

The US Court of Appeals for the Federal Circuit affirmed a Patent Trial & Appeal Board obviousness-type double patenting rejection, finding that an unexpected mechanism of action does not render the known use of a known compound nonobvious. In re: Institut Pasteur, Case No. 22-1896 (Fed. Cir. Dec. 13, 2023) (Taranto, Clevenger, Stoll, JJ.) (nonprecedential).

Institut Pasteur filed a patent application directed to peptides derived from human basic proline-rich lacrimal protein and claimed, among other things, a method for treating pain comprising of administering 10 to 300 mg/day of the peptide for seven days. The examiner rejected the claims for obviousness-type double patenting over another patent application filed by Pasteur, which was directed to diagnostic and therapeutic uses of human basic proline-rich lacrimal protein and peptides derived therefrom.

Pasteur appealed to the Board, which affirmed the examiner’s rejection. Rather than appeal the Board’s decision to the Federal Circuit, Pasteur sought continued examination of the application and modified the claims to specify that the method of treatment was for human patients, was in a dose of 1 mg/kg to 2 mg/kg at 10 to 300 mg/day, and should not induce pharmacodependence or tolerance in the patient. The examiner rejected the amended claims for obviousness-type double patenting over the same application. On appeal, the Board issued another decision agreeing with the examiner. Pasteur appealed this decision.

Pasteur argued that the Board’s second decision was unsupported by substantial evidence because the Board applied a legally flawed prima facie obviousness analysis and disregarded the secondary indicia of nonobviousness presented in a declaration submitted by Catherine Rougeot, the named inventor of the application.

The Federal Circuit disagreed with Pasteur and affirmed the Board’s rejection. As for Pasteur’s argument that the Board disregarded the differences between the claims of the patent application and the claims of the other application, the Court noted that the Board “explained why each claim limitation was obvious in light of the [other application].” With respect to Pasteur’s argument that the Board improperly relied on inherency when finding one limitation of the filed application to be satisfied, the Court concluded that “[i]t is settled that inherency may supply a missing claim limitation in an obviousness analysis.”

As for Pasteur’s challenge to the Board’s consideration of the secondary indicia of nonobviousness presented in the Rougeot declaration, the Federal Circuit found that the Board’s analysis was supported by substantial evidence. The Court made clear that Pasteur failed to prove that the benefits claimed by the application were unexpected compared to the closest prior art since unexpected mechanisms of action do not ipso facto make the known use of known compounds nonobvious. The Court also noted that Federal Circuit precedent did not demand a finding of nonobviousness simply because one limitation was found to be satisfied through inherency. The Court was similarly unpersuaded by the long-felt need described in the Rougeot declaration because any need for the subject matter claimed by the patent application was already satisfied by the subject matter claimed by the other [...]

PTO Creates Separate Design Patent Bar

The US Patent & Trademark Office (PTO) published its final rule, creating a separate design patent bar where admitted design patent practitioners will practice in design patent proceedings only. (88 Fed. Reg. 78644 (Nov. 16, 2023).)

Prior to this rulemaking, there was a single patent bar for those who practice in patent matters before the PTO, including in utility, plant and design patent proceedings. PTO regulations previously required that all patent bar practitioners pass a registration exam and possess specific and stringent scientific and technical qualifications, such as an engineering degree or substantial course work in physics, biology, chemistry or the like.

The new rule creates a separate design patent bar that still requires members to pass the current registration exam but permits applicants to have a bachelor’s degree, master’s degree or PhD in any of the following areas from an accredited college or university:

  • Industrial design
  • Product design
  • Architecture
  • Applied arts
  • Graphic design
  • Fine/studio arts
  • Art teacher education.

The new rules expanding the patent bar admission criteria are intended to encourage broader participation and to keep up with the ever-evolving technology and related teachings that qualify someone to practice before the PTO. Practitioners currently admitted before the PTO will not be impacted by the change and can continue to prosecute utility, plant and design patents.

The rule will take effect on January 2, 2024.

PTO Provides Guidance for Computer-Related Design Patent Applications

The US Patent & Trademark Office (PTO) published a notice regarding supplemental guidance for PTO personnel examining design patent claims containing computer-generated images. 88 Fed. Reg. 80277 (Nov. 17, 2023).

The guidance clarifies how to satisfy the article of manufacture requirement under 35 U.S.C. 171 for ornamental designs relating to computer-generated icons shown on a display panel, as discussed in Section 1505.01(a)(I) of the Manual of Patent Examining Procedure (MPEP). According to the guidance, “the mere display of a computer-generated electronic image . . . on a display panel does not constitute statutory subject matter under 35 U.S.C. 171.” However, a computer icon or a graphical user interface (GUI) shown on a display panel (e.g., a computer screen, monitor, computer display system, mobile phone screen or virtual/augmented reality goggles) is more than a mere display of a picture on a screen because it constitutes an integral and active component in the operation that is embodied in and/or applied to a programmed computer displaying the computer icon or the GUI. Thus, if a computer icon or GUI is properly presented and claimed (e.g., the drawing fully discloses the design as embodied in the article of manufacture), it is eligible under 35 U.S.C. 171.

In addressing the foregoing distinctions, the guidance sets forth specific standards for PTO personnel, including consideration of the complete disclosure when evaluating whether a design claim containing a computer-generated electronic image complies with the article of manufacture requirement. For example, given that computer icons or GUIs are considered to be two-dimensional images, which standing alone are surface ornamentation (i.e., an ornament, impression, print or picture), the guidance stipulates that the title and the claim should not be for a computer icon or a GUI alone, but rather an article of manufacture, such as a “display panel with a computer icon.” The guidance further provides examples of acceptable claim language and specific examination scenarios for evaluation.

Distinguishing Drinkware—Provisional Priority Determined Differently in Pre- and Post-AIA Patents

In a precedential final written decision, the Patent Trial & Appeal Board concluded that a patent does not need to contain a claim supported by a provisional application’s disclosure to draw priority to that provisional for prior art purposes post America Invents Act (AIA). Penumbra, Inc. v. RapidPulse, Inc., IPR2021-01466, paper 34 (PTAB Mar. 10, 2023) (designated precedential Nov. 15, 2023) (Melvin, Cotta, Wisz, APJs).

Penumbra filed an inter partes review (IPR) petition targeting a patent directed to a “thrombectomy system,” which is a system for removing blood clots in the brain. Penumbra challenged the claims on four different grounds, and each included the Tiegen reference. Therefore, the petition would fail if the Tiegen reference was not prior art.

The challenged patent was filed on July 18, 2019, and drew priority to a provisional application filed on October 24, 2018. Tiegen drew priority to two provisional applications—one dated December 12, 2018, and another dated July 24, 2018. Whether Tiegen was prior art thus depended on whether the challenged patent could draw priority to its provisional application, and whether Tiegen could draw priority to its July 24, 2018, provisional. RapidPulse challenged Tiegen on both bases.

First, the Board assessed the proper priority date for the challenged patent. The Board explained that in order for the patent to draw priority to its provisional application, that provisional application had to provide written support for the challenged patent’s claims. Penumbra argued that the challenged patent’s provisional application did not have written support for the claimed “prevent[ing] forward flow.” RapidPulse responded, arguing that the disclosure of a “minimal amount of momentum from the fluid column” disclosed the claimed “preventing forward flow.” Forward flow generates momentum from the fluid column, so minimizing momentum required preventing fluid flow, according to RapidPulse. RapidPulse also pointed to embodiments that had substantially no forward flow from the distal end of the system.

Penumbra responded by explaining that the provisional application required forward flow in some embodiments, and nothing in the specification stated that the flow should be prevented. The Board agreed, explaining that the provisional application included embodiments with forward flow, and while the provisional recited some embodiments with small amounts of forward flow, the provisional did not indicate that the low forward flow was significant. The Board observed that “one cannot disclose a forest in the original application, and then later pick a tree out of the forest.”

Having determined that the priority date of the challenged patent was July 18, 2019, the Board turned to the priority date of Tiegen. The Board distinguished the present case over Dynamic Drinkware, a 2015 US Court of Appeals for the Federal Circuit case. Dynamic Drinkware states that for prior art purposes, a prior art patent can only draw priority to a provisional application if the prior art patent contains a claim supported by that provisional application. The Board explained that Dynamic Drinkware does not apply post-AIA. Instead, the Board found that, based on the language of AIA 35 [...]

PTO Director Requests Input on Patent Trial & Appeal Board Decision Regarding Duty of Candor

On May 3, 2023, the Patent Trial & Appeal Board granted a motion for sanctions brought by Spectrum Solutions LLC against Longhorn Vaccines & Diagnostics LLC.[1] The resulting sanctions order canceled five Longhorn patents. The Board found that Longhorn failed to meet its duty of candor by selectively and improperly withholding material results inconsistent with its patentability arguments directed to the canceled claims covering chemical compositions, collection systems and methods for biological specimen collection, including preserving biological samples, killing pathogens and preventing nucleic acid degradation. Now, US Patent & Trademark Office (PTO) Director Katherine Vidal has initiated sua sponte review of the Board’s sanctions order.

In her order issued October 27, 2023, the Director authorized further briefing by both parties, as well as amicus curiae briefs in response to the Board’s decision and analysis for the Director’s review. The Director particularly seeks input on the following issues in the context of situations where relevant factual evidence has been withheld during an America Invents Act proceeding:

  • Which PTO regulations are implicated? Do such regulations include 37 C.F.R. § 1.56?
  • Is it an appropriate sanction for the Board to deem the claims unpatentable in its written decision? Is such a sanction proportionate to the harm caused by the party, taking into account the integrity of the patent system?
  • What other sanctions are appropriate, either in addition to or in place of applying adverse judgment in a final written decision to deem claims unpatentable?

Amicus briefs (of no more than 20 pages) limited to the issues and questions identified above should be submitted to Director_PTABDecision_Review@uspto.gov no later than four weeks after the October 27, 2023, entry date of the order.

For further details, see Order (Paper 133) in each of the listed IPR proceedings.

Chilly Adventures: Design Patent Prior Art Comparison Applies to Article of Manufacture

Addressing a matter of first impression concerning the scope of prior art relevant to a design patent infringement analysis, the US Court of Appeals for the Federal Circuit concluded that “to qualify as comparison prior art, the prior-art design must be applied to the article of manufacture identified in the claim.” Columbia Sportswear North America, Inc. v. Seirus Innovative Accessories, Inc., Case Nos. 21-2299; -2338 (Fed. Cir. Sept. 15, 2023) (Prost, Reyna, Hughes, JJ.)

Columbia owns a design patent that covers an ornamental design of a heat reflective material. Seirus markets and sells products (e.g., gloves) made with material that it calls HeatWave. An image of Columbia’s patented design and Seirus’s HeatWave material appear below:

Columbia Patented Design

Seirus HeatWave

Columbia sued Seirus for infringement. After the district court granted summary judgment of infringement, Seirus appealed to the Federal Circuit. The Court issued its decision in Columbia I, concluding that the district court improperly declined to consider the effect of Seirus’s logo in its infringement analysis and resolved certain issues that should have been left to the jury. The Court therefore vacated summary judgment and remanded for further proceedings.

On remand, the district court held a trial. Before trial, the district court limited admissible comparison prior art to “wave patterns of fabric,” declined to instruct the jury that “prior art” referred to prior designs of the claimed article of manufacture, and declined to instruct the jury that it did not need to find that any purchasers were deceived or that there was any actual or likelihood of confusion among consumers in the marketplace. Seirus was permitted to admit three prior art references that disclosed fabric, and Columbia was precluded from distinguishing the references by arguing that they did not disclose heat reflective material. The jury returned a verdict of noninfringement. Columbia appealed.

Among other things, Columbia challenged the exclusion of evidence and jury instructions concerning comparison prior art, and the jury instructions implicating Seirus’s logo.

The Federal Circuit began by discussing the appropriate prior art comparison in the context of design patent infringement. Citing its 2008 en banc decision in Egyptian Goddess v. Swisa, the Court explained that under the ordinary-observer test governing design patent infringement, prior art can help highlight distinctions and similarities between the claims and the accused design. For instance, when a claimed design is close to a prior art design, small differences between the accused design and the claim design are likely to be important. Conversely, if an accused design copied a particular feature of the claimed design that departs from the prior art, the accused design is likely to be regarded as deceptively similar to the claimed design, and thus infringing.

The question of first impression before the Federal Circuit was the proper scope of comparison prior art that may be [...]

PTO Issues Oral Hearing Guide for Patent Trial & Appeal Board Proceedings

On August 31, 2023, the US Patent & Trademark Office (PTO) published an Oral Hearing Guide to aid parties with oral arguments before the Patent Trial & Appeal Board. The newest Oral Hearing Guide updates the 2019 Oral Hearing Guide published on August 30, 2019, and is meant to be read in conjunction with the procedures set forth in the 2019 PTAB Trial Practice Guide.

The Oral Hearing Guide addresses the following topics:

  • PTO locations for oral hearings
  • Request for an oral hearing
  • Notification of hearing in ex parte and reexamination hearings
  • Notification of hearing in America Invents Act (AIA) trials
  • Authorized persons to present oral arguments
  • Attendance at hearings
  • Guidelines for counsel during argument.

With a few minor exceptions, the administrative processes and procedures largely mirror those set forth in the 2019 Oral Hearing Guide and the 2019 PTAB Trial Practice Guide. The key changes are summarized below.

A Request for Oral Hearing in ex parte and reexamination proceedings must be filed as a separate paper with the required fee paid within a non-extendable time period. The Board will issue a Notice of Hearing to the parties involved once a case has been scheduled for oral argument, typically eight weeks before the scheduled hearing session. The Notice of Hearing provides information about the scheduled hearing, including the date, time, location, appearance options and general information about the oral hearing procedures before the Board.

In trial proceedings under the AIA—i.e., inter partes reviews (IPRs), covered business method reviews (CBMs or CBMRs), post-grant reviews (PGRs) and derivations—each party to a proceeding is afforded an opportunity to present its case before at least three members of the Board and is notified of the date and location options of an oral hearing in a Scheduling Order. The Guide further elaborates on the processes for requesting an oral argument, including the issuance of the Notice of Hearing (or Scheduling Order) when an oral hearing is requested. The Scheduling Order notifies the parties of the finalized hearing date, time and location. Once the Board has issued a Hearing Order, parties requiring a different arrangement should contact the Board with their request.

The Guide stipulates that the parties should state in their respective requests for oral argument whether they prefer a video hearing or an in-person hearing, and for in-person hearings, which available location the party prefers. To the extent the parties disagree, they should meet and confer. If the dispute cannot be resolved by meeting and conferring, the parties should inform the Board of each party’s individual preferences. The Board will notify the parties of its decision in accordance with current office policy.

The Guide further provides updated information stipulating that optional demonstrative exhibits must be marked with the words “DEMONSTRATIVE EXHIBIT – NOT EVIDENCE” in the footer and further elaborates on the procedures for parties to request pro hac vice admission for non-registered patent practitioners to participate in proceedings. Finally, the Guide discusses [...]
