Initial Confusion? Relax, Eighth Circuit Has Your Number

Addressing a novel issue regarding when confusion must occur for it to be actionable, the US Court of Appeals for the Eighth Circuit concluded that initial-interest confusion was a viable infringement theory. Select Comfort Corp. v. Baxter, Case No. 19-1113 (8th Cir. May 11, 2021) (Melloy, J.)

Select Comfort owns registered trademarks, including “SELECT COMFORT,” “SLEEP NUMBER” and “WHAT’S YOUR SLEEP NUMBER,” for adjustable air mattresses, which it sells online and in stores across the United States. Baxter sells competing air mattresses online and through a call center. Select Comfort brought a suit asserting trademark infringement, trademark dilution and false advertising theories against Baxter. Select Comfort alleged that Baxter used Select Comfort’s registered trademarks in an identical or confusingly similar manner to advertise Baxter’s mattresses and divert consumers to its website and phone lines instead of Select Comfort’s. Select Comfort also alleged that Baxter made false representations about its products and failed to dispel consumer confusion about the products. At trial, Select Comfort pointed to similar terms in Baxter’s online advertising text, graphics and domain addresses, in addition to examples of actual confusion about the products in Baxter’s call-center transcripts.

Earlier in the case, in connection with summary judgment, the district court found that the relevant consumers were sophisticated as a matter of law, and, citing Eight Circuit precedent, rejected application of a theory of initial-interest confusion. The district court instead instructed the jury that in order to prevail on its trademark infringement claim, Select Comfort had to prove likelihood of confusion at the time of purchase. Based on this limiting instruction, the jury rejected Select Comfort’s trademark infringement claims. Select Comfort appealed.

The Eighth Circuit reversed. The Court explained that the district court erred on the availability of an initial-interest confusion as an infringement theory. For trademark infringement claims, the likelihood of confusion test is a fact-intensive inquiry with many factors. However, circuit courts have not definitively agreed on when confusion must exist. Must confusion occur only at the time of ultimate purchase, or can it also exist during pre-sale? The theory of initial-interest confusion involves the latter scenario, namely, when confusion about a product’s ownership causes a customer to have initial interest in the product, even if there is no actual sale at the time of the confusion. Actionable initial infringement protects competitors from getting a free ride on the goodwill of an established mark if a consumer falsely infers an affiliation between the companies.

In the precedential 2010 Eighth Circuit case Sensient Techs. v. Sensory Effects Flavor, the Court neither rejected nor adopted the initial-interest/pre-sale confusion theory. Instead, it merely found that the theory did not apply where consumers were sophisticated (i.e., where they exercise a high degree of care in purchasing products, a factor weighing against likelihood of confusion). Here, influenced by Lanham Act amendments and other circuit courts, the Court addressed the issue previously left open: whether the initial-interest confusion may be actionable in the Eighth Circuit in cases where the jury is left to [...]

New Perspective on Specific Personal Jurisdiction in Patent DJ Venue

The US Court of Appeals for the Federal Circuit concluded that the minimum contacts or purposeful availment test for specific personal jurisdiction was satisfied where a patent owner sent multiple infringement notice letters and other communications to a resident of California who then filed for declaratory judgment of non-infringement in federal district court in California. Trimble Inc. v. PerDiemCo LLC, Case No. 19-2164 (Fed. Cir. May 12, 2021) (Dyk, J.)

PerDiem accused Trimble of infringing several of PerDiem’s patents. PerDiem exchanged 22 communications with Trimble in California over a period of three months, some through Trimble’s subsidiary ISE in Iowa and other communications through its chief IP counsel in Colorado. The communications started with a letter (sent to ISE in Iowa) that had attached an unfiled complaint and which PerDiem used to try to launch license negotiations. This unfiled complaint asserted nine of PerDiem’s patents. After ISE brought Trimble, its parent, into the discussion, PerDiem accused Trimble’s products of infringing 11 patents and sought to enter into binding mediation on its infringement allegations. PerDiem also threatened to sue Trimble in the Eastern District of Texas and identified the counsel it planned to use for this purpose. Trimble filed for a declaratory judgment of non-infringement in the Northern District of California. The district court dismissed the complaint, relying on the Federal Circuit’s 1998 decision in Red Wing Shoe v. Hockerson-Halberstadt, concluding that it would be unreasonable to assert personal jurisdiction over PerDiem based on its communications. Trimble appealed.

The sole issue in the appeal was whether the district court erred in holding that there was no specific personal jurisdiction over PerDiem in the Northern District of California. The Federal Circuit explained that PerDiem’s contacts with California were far more extensive than those in Red Wing, noting the manner in which PerDiem amplified its threats of infringement as the communications continued, asserted more patents, and accused more of Trimble and ISE’s products of infringement. The Court noted that PerDiem even identified the counsel it retained to sue Trimble and the venue in which it planned to file suit. Overall, the Court found that PerDiem’s 22 communications over the course of about three months fell well outside the “sufficient latitude” the Court sought to grant patentees “to inform others of [their] patent rights without subjecting [themselves] to jurisdiction in a foreign forum” on the basis of three letters sent over a similar time period in Red Wing.

Practice Note: It remains to be seen how useful this case may be in the context of obtaining specific personal jurisdiction over non-practicing entities (or other patent owners) based on sending demand letters into a potential declaratory judgment venue viewed as less hospitable to patent owners.

Arthrex Argument May Be Available in Round Two

The US Court of Appeals for the Federal Circuit found that a party did not waive the Patent Trial & Appeal Board’s (Board) constitutionality argument by raising it for the first time in its opening brief because the Court’s decision in Arthrex, Inc. v. Smith & Nephew, Inc. was issued after the party sought rehearing. New Vision Gaming v. SG Gaming, Inc., Case Nos. 20-1399, -1400 (Fed. Cir. May 13, 2021) (Moore, J.) (Newman, J. concurring in part, dissenting in part)

New Vision appealed two covered-business method (CBM) review final written decisions in which the Board found that all claims of the patents, as well as its proposed substitute claims, were directed to patent ineligible subject matter under 35 U.S.C. § 101. In its opening brief before the Federal Circuit, New Vision requested the Court vacate and remand the Board’s decisions in light of Arthrex. SG Gaming argued New Vision had waived its right to a challenge under Arthrex since it raised it for the first time on an appeal. The Court disagreed, finding that New Vision had not waived its ability to challenge the Board’s decision under Arthrex since Arthrex was issued after the Board’s final written decisions and after New Vision sought Board rehearing. The Court vacated the Board’s final written decisions in the CBMs and remanded for further proceedings consistent with Arthrex without reaching the merits or any other issues.

In her partial dissent, Judge Pauline Newman agreed that Arthrex applied and vacating the Board’s final written decisions was appropriate. She also argued that another threshold issue (venue) should have been resolved, rendering the remand under Arthrex unnecessary and unwarranted. Additionally, Judge Newman agreed with New Vision that since the parties agreed to a different forum for dispute resolution in their license agreement, compliance with the parties’ patent license agreement would be appropriate. Under that agreement, if “any dispute” arose, jurisdiction would be “exclusive” in the appropriate federal or state court in the state of Nevada. New Vision filed suit in the federal district court in Nevada before SG filed CBM petitions before the Board. The Board stated it “[does] not discern, nor has Patent Owner pointed to, any portions of chapter 32 or § 18 of the AIA, or authority otherwise, that explicitly provide for a contractual estoppel defense,” in its decision and proceeded to a final decision despite the forum selection agreement.

Both parties briefed the forum selection question, with New Vision citing the Federal Circuit 2019 decision in Dodocase VR v. MerchSource in which a case was removed from the Board based on an agreed choice of forum. SG countered that the Board’s rejection of choice of forum is an unreviewable “institution” decision under Thryv vs. Click-to-Call. Andrei Iancu, the Director of the US Patent and Trademark Office (USPTO), intervened in the appeal, arguing that the Board’s decision is “final and nonappealable” under 35 U.S.C. § 324(e). As to the Board’s “conduct” in declining to [...]

Prosecution History Prevents Patent Owner from “Intercepting” Win on Appeal

In reviewing whether the Patent Trial & Appeal Board (Board) correctly interpreted the meaning of “intercepting” in the context of Voice over Internet Protocol (VoIP) technology, the US Court of Appeals for the Federal Circuit found that the claim language and prosecution history supported the Board’s decision. The Court thus affirmed the Board’s construction and subsequent finding of obviousness. Uniloc 2017 LLC v. Apple Inc., Case Nos. 20-1403, -1404 (Fed. Cir. May 12, 2021) (Prost, C.J.)

Uniloc owns a patent directed to a system and method for using various VoIP features, such as caller-ID, call waiting, multi-line service, and different levels of service quality known as the “codec specification.” The patent explains that in order to generate revenue for these features, service providers must maintain control over which subscribers have paid for these additional features. To achieve that control, the system employs an enforcement mechanism that sits between the sender of the communication and the intended recipient. The enforcement mechanism ensures that both parties are authorized to use the particular features by intercepting the signaling message, determining whether the client is authorized, and filtering the signaling message based on the authorization. The majority of the claims require authorization related to only one service type. However, one of the claims (claim 18) requires authorization related to at least two service types.

Apple filed a petition for inter partes review (IPR), alleging that all claims of the patent were invalid as obvious over a prior art patent referred to as Kalmanek. Kalmanek discloses signaling messages that are routed through at least one “gate controller,” which can authenticate the identity of the calling party and authorize the services sought. The services include at least caller-ID and enhanced levels of call quality. Kalmanek’s process is accomplished by sending a SETUP message, which the calling party sends to the gate controllers and then to the intended recipient. After receipt, the called party sends a SETUPACK message along a return path to the gate controllers and then to the caller.

During the IPR, Apple asserted that the term “intercepting” a signaling message associated with the call, as recited in all independent claims, should be interpreted to mean “the signaling [message] is received by a network entity located between the endpoints of the call.” Uniloc disagreed and argued that the term should be interpreted as excluding the receipt of a signaling message by the intended recipient of the message. The Board agreed with Apple’s construction and subsequently found that all terms were invalid as obvious with the exception of claim 18. With respect to claim 18, the Board concluded that Apple failed to meet its burden to show that Kalmanek disclosed authorization related to a codec service. Furthermore, the Board opined that even assuming Apple had properly advanced such an argument, it would have lost on the merits.

On appeal, Uniloc challenged the Board’s construction of the “intercepting” term, and Apple cross-appealed the Board’s finding with respect to the non-obviousness of claim 18. The Federal Circuit affirmed [...]

Full Scope of Claimed Invention Must Be Enabled

In a case relating to nucleic acid sequencing, the US Court of Appeals for the Federal Circuit upheld a jury verdict of non-enablement because a skilled artisan would have only known how to successfully practice a narrow range of the full scope of the nucleic acids covered by the asserted claim at the time of the invention. Pacific Biosciences of California, Inc. v. Oxford Nanopore Technologies, Case No. 21-2155, -2156 (Fed. Cir. May 11, 2021) (Taranto, J.)

PacBio sued Oxford for infringement of two patents related to methods for sequencing nucleic acids (such as DNA) using nanopore technology. The methods involve drawing nucleic acids through a nanometer-sized hole formed in a substrate. A voltage is applied to the substrate, and as the nucleic acids pass through the hole, the identity of each nucleic acid is identified based on changes in electric current passing through the substrate.

At trial, Oxford’s lawyer made opening remarks that included references to the potential applications of Oxford’s accused products to the then-emerging global COVID-19 crisis. PacBio immediately objected, and the district court gave exactly the curative instruction that PacBio requested. The district court also required that going forward, the parties give advance notice if they intended to make any reference to COVID-19. Ultimately, the jury found all asserted claims infringed, but also determined that the claims were invalid for lack of enablement under 35 USC § 112. In post-trial motions, the district court denied PacBio’s request that the court grant a new trial because of Oxford’s remark during opening statements regarding the accused products’ potential application to the then-emerging COVID-19 crisis. PacBio appealed.

On appeal, PacBio argued that the jury’s finding of lack of enablement was unsupported by the evidence, citing to testimony from its expert that a person skilled in the art at the priority date would have been able to successfully perform the methods of the asserted claims. The Federal Circuit disagreed, noting that the expert only demonstrated successful practice of the asserted claims for a narrow subset of nucleic acids covered by the claims—namely DNA hairpin molecules. The Court cited evidence where PacBio admitted through a stipulation that it had never performed the nanopore sequencing methods of the asserted claims, meaning its reduction to practice was purely constructive. The Court also noted that Oxford produced evidence that it was not until 2011 (two years after the priority date) that anyone in the field was able to use nanopore sequencing to sequence biological DNA—a different type of nucleic acid within the scope of the asserted claims. Thus, the Court found that PacBio had only demonstrated that a person of skill in the art would have been able to successfully practice a narrow range of the full scope of the nucleic acids covered by the asserted claim. The Court explained that it is not enough for enablement that the relevant artisans knew how to perform some nanopore sequencing before the priority date. Instead, what matters is the scope of the asserted claims, which relate [...]

Targeted Advertising Still Patent Ineligible Subject Matter

The US Court of Appeals for the Federal Circuit found that targeted advertising is still an abstract idea and that a system providing targeted advertising must utilize something more than generic features and routine functions to be eligible for patent protection. Free Stream Media Corp. v. Alphonso Inc., Case No. 19-1506 (Fed. Cir. May 11, 2021) (Reyna, J.)

Free Stream Media, d.b.a. Samba, owns a patent directed to “a system providing a mobile phone user with targeted information (i.e., advertisements) that is deemed relevant to the user based on data gathered from the user’s television.” The system has three main components: (1) a networked device (e.g., a smart TV) that collects primary data, including program information, location, weather information or identification information; (2) a client device (e.g., a mobile device) on which applications run and advertisements may be shown; and (3) a relevancy-matching server that uses the primary data to select advertisement or other targeted data based on a relevancy factor associated with the user. Specifically, the relevancy-matching server “may also be configured to render the targeted data to the user through the networked device and/or the sandboxed application of the client device.”

Samba asserted infringement of the patent against Alphonso. In response, Alphonso filed a motion to dismiss on grounds that the asserted claims of the patent were directed to patent ineligible subject matter under 35 USC § 101. Alphonso subsequently filed a motion for summary judgment of non-infringement. The district court denied the § 101 motion but granted the summary judgment motion. Samba appealed the non-infringement finding, and Alphonso cross-appealed the § 101 finding.

The Federal Circuit started with the § 101 finding by first addressing Alice step 1 (abstract idea). The Court rejected the district court’s finding that the asserted claims were directed to “systems and methods for addressing barriers to certain types of information exchange between various technological devices . . . being used in the same place at the same time,” i.e., to bypass the security sandbox, and not an abstract idea of tailored advertising. To the contrary, the Court found that the asserted claims were directed precisely to the abstract idea of tailored advertising—specifically, gathering information about television users’ viewing habits, matching the information with other content and sending that content to a second device. Reiterating its prior holdings with respect to Alice step 1, the Court explained that the asserted claims only provided for the result of overcoming a security sandbox, and did not at all describe how that result is achieved. The Court also explained that even if the claims did recite a method for bypassing a security sandbox, Samba failed to demonstrate that this was anything more than a mere use of a computer as a tool, or that it somehow “improves the operability of these devices beyond providing a user with targeted content using generic processes and machinery.”

Turning to Alice step 2 (inventive concept), the Federal Circuit explained that the claimed abstract idea of providing targeted advertisements was not [...]

Use is ACTUALLY Measured by Benefit

Addressing whether a service mark owner had established a protectable interest in his marks through actual or analogous use, the US Court of Appeals for the 10th Circuit reversed in part the district court’s grant of summary judgment for the alleged infringer, explaining that by focusing on sales, the district court applied the wrong legal standard for analyzing actual use. Underwood v. Bank of Am. Corp., Case Nos. 19-1349, 20-1087 (10th Cir. Apr. 30, 2021) (Matheson, J.)

In 2010, Erik Underwood and My24HourNews.com (collectively, Underwood) applied for, and were granted, registration of a service mark in Georgia for a computer-animated woman named Erica who verbally reports the news through cell phones and computer programs. In 2012, Underwood registered the domain name for a website, my24erica.com. On the website, E.R.I.C.A. could answer questions and offer recommendations regarding movies and television shows. In 2016, Bank of America filed an intent to use application with the US Patent and Trademark Office for ERICA, a mark for goods and services including voice-controlled information, personal assistant banking and finance services. Underwood sued Bank of America, alleging common law service mark infringement of two marks, E.R.I.C.A. and my24erica.com.

The district court granted summary judgment for Bank of America, concluding that Underwood had not established a protectable interest in either of the marks through actual or analogous use. Underwood appealed.

The 10th Circuit concluded that the district court applied the wrong legal standard and committed two legal errors in its analysis of the issue of actual use of the E.R.I.C.A. mark. First, the district court erred by assuming that in order to establish actual use, Underwood’s customers must have purchased the services offered or Underwood must have generated revenue, because actual use is measured by benefit—not sales to third parties. Second, the district court erred by limiting the services at issue to those listed on the Georgia registration (i.e., newscasting). Instead, the district court should have considered all services identified by the mark, including those on the my24erica.com website (i.e., search engine and personal assistant services). The Court remanded the issue of actual use to permit the district court to address the factual issues under the correct legal standard.

Analogous use of a mark is use in commerce that is non-transactional, e.g., promotional efforts for the goods or services, such as advertising brochures, catalogs, newspaper ads, and articles in newspapers and trade publications. Although actual use need not have a substantial impact on the purchasing public, analogous use must be “of such a nature and extent as to create public identification of the target term with the [user’s] product or service.” To qualify as analogous use, the use must be open and notorious, i.e., “of such a nature and extent that the mark has become popularized in the public mind so that the relevant segment of the public identifies the marked goods with the mark’s adopter.” Because the analogous use in terms of the E.R.I.C.A. mark had large gaps in time; consisted only of PowerPoint presentations at [...]

Tax Court Allows Partial Deduction, Requires Partial Capitalization of Generic Drug Approval Legal Expenses

The US Tax Court determined that a pharmaceutical manufacturer’s legal expenses incurred to defend against a patent infringement suit were eligible for an immediate deduction as ordinary and necessary business expenses, while legal expenses incurred as part of an abbreviated new drug application (ANDA) were not eligible for an immediate deduction and thus had to be capitalized and then amortized over 15 years. Mylan, Inc. & Subsidiaries v. Commissioner, 156 T.C. No. 10 (Apr. 27, 2021) (Urda, J.)

The ANDA process allows for faster approval of a generic drug if the manufacturer can show that the generic drug is sufficiently similar to an approved brand name drug. As part of the ANDA process, the generic manufacturer must file statements certifying that the generic drug does not infringe any brand drug patents, or that such patents are invalid. The generic manufacturer also must send a notification to the holder of any patents covered by the certification statements.

Mylan filed several ANDAs for generic versions of brand name drugs, including Celebrex, Lunesta and Nexium, during the tax years at issue in the case. Considerable legal expenses were incurred as part of filing the ANDAs and making the required certifications and notifications. As a result of those certifications and notifications, patent holders brought approximately 120 patent infringement suits against Mylan. Mylan defended itself against the infringement suits, incurring litigation expenses.

In general, taxpayers may take an immediate deduction for ordinary and necessary business expenses. However, taxpayers must capitalize expenditures that create or enhance a distinct asset or otherwise generate benefits for taxpayers beyond a single tax year. Special rules apply to determine whether expenses related to an intangible asset should be capitalized. The income tax regulations provide that a “taxpayer must capitalize amounts paid to a governmental agency to obtain, renew, renegotiate, or upgrade its rights under a trademark, trade name, copyright, license, permit, franchise, or other similar right granted by that governmental agency.” Taxpayers must also capitalize an amount paid to facilitate an acquisition or creation of an intangible.

Litigation expenses for patent suits may be deducted or must be capitalized depending on the nature of the litigation. Defense of title claims are treated as the acquisition or disposition of a capital asset and must be capitalized. In contrast, patent infringement claims arise in tort and can be deducted in the year the expense is incurred.

Applying these rules to Mylan’s legal expenses, the Tax Court held that expenses related to the preparation of the ANDA, including the certifications and notices, were capital expenses to acquire or create an intangible asset and had to be recovered incrementally over 15 years. However, the Tax Court held that the costs of defending against patent infringement suits is an ordinary and necessary business expense for a generic drug manufacturer and permitted Mylan to deduct its litigation expenses in the year the expense was incurred.

Federal Circuit Puts Patent Infringement Award/Injunction Back in the Box

The US Court of Appeals for the Federal Circuit, exploring the use of Federal Rule of Civil Procedure 60(b)(3) under Ninth Circuit law, affirmed a district court’s ruling setting aside a monetary damages judgment and an injunction for fraudulent misrepresentations by a corporate patent owner’s president concerning prior art. Cap Export, LLC, et al. v. Zinus, Inc., et al., Case No. 20-2087 (Fed. Cir. May 5, 2021) (Dyk, J.)

In 2016, Cap Export sued Zinus seeking a declaratory judgment that claims of a patent owned by Zinus were invalid and not infringed. Zinus countersued, alleging that Cap Export infringed its patent covering a bed frame that can be packed into the headboard for compact shipping (known as a “bed in a box”). Zinus filed a motion for partial summary judgment of no invalidity of certain claims, and the court allowed Cap Export to depose Zinus’s then-president and “testifying technical expert,” Colin Lawrie. During the deposition, Lawrie denied knowledge of the existence of prior art. The district court concluded that the claims were not invalid and entered a judgment and permanent injunction against Cap Export.

Shortly thereafter, Zinus sued another company for patent infringement, and Cap Export discovered an exhibit on the docket describing a sale to Zinus of a bed that had all of the components of the bed (except the headboard) packed inside a zippered compartment in the headboard. Cap Export contacted the third party that sold the prior art beds to Zinus and obtained an invoice bearing the signature of Lawrie, the same witness who denied knowledge of such beds during his deposition. Cap Export moved to vacate the judgment and injunction on the grounds of fraud and misrepresentation under Rule 60(b)(3). After the district court granted the motion, Zinus appealed.

The Federal Circuit analyzed the issue under Ninth Circuit law, which requires evidence that the verdict was obtained through fraud, misrepresentation or other misconduct, and that the conduct prevented the losing party from fully and fairly presenting its defense. Ninth Circuit law further requires that the fraud was not discoverable by due diligence before or during the proceedings. Zinus argued that Cap Export’s counsel should have discovered the emails if they had exercised due diligence and propounded standard document requests for a patent case. Cap Export did not dispute that its written discovery served on Zinus did not specifically seek prior art and that it did not depose the inventor of the patent. Cap Export also did not dispute that although Lawrie’s deposition was taken, it was not taken under Federal Rule of Civil Procedure 30(b)(6).

The Federal Circuit explained that the issue was not whether Cap Export’s conduct fell below the standard of care for attorneys practicing patent litigation, but rather whether a reasonable company in Cap Export’s position should have had reason to suspect the fraud—i.e., that Lawrie had testified falsely—and, if so, whether it took reasonable steps to investigate. The Court found no showing that there was reason to suspect that Lawrie’s statements were [...]

Blueprint Blooper: Floor Plan Copyright Infringement Requires Virtually Identical Copying

Addressing whether a home builder’s floor plans infringed the plaintiff’s architectural copyrights, the US Court of Appeals for the Seventh Circuit affirmed a lower court’s entry of summary judgment against the plaintiff, finding that only a virtually identical design would infringe the plaintiff’s “thin copyright” in its floor plans. Design Basics, LLC v. Signature Construction, Inc., Case No. 19-2716 (7th Cir. Apr. 23, 2021) (Sykes, J.)

Design Basics, described bluntly by the Seventh Circuit as a “copyright troll,” holds copyrights in thousands of floor plans for suburban single-family homes. Design Basics sued Signature Construction (Signature) for infringement of 10 of its designs. Discovery showed that Signature held copies of four of Design Basics’ designs, one of which had been marked up by a Signature employee. Signature moved for summary judgment, relying on a 2017 Seventh Circuit opinion in Basic Designs v. Lexington Homes in which the Court found that Design Basics’ copyright protection in its floor plans was “thin.” The district court granted summary judgment against Design Basics, and this appeal followed.

Relying heavily on Lexington Homes, the Seventh Circuit took the opportunity to clarify the elements of a prima facie case of copyright infringement for works with “thin” copyright protection. The Court explained that to establish infringement, the plaintiff must prove (1) ownership of a valid copyright and (2) copying of original elements of the work. Because ownership was not contested in this case, the Court focused on the copying element. The Court explained that “copying” constitutes two separate questions: Whether the defendant actually copied the plaintiff’s protected work (as opposed to creating it independently) and whether the copying constituted wrongful copying, also known as unlawful appropriation.

Because there is rarely direct evidence of copying, circumstantial evidence may be used to infer actual copying, the Seventh Circuit explained. Proving actual copying by circumstantial evidence requires evidence of access to the plaintiff’s work and evidence of substantial similarity between the two works. The analysis of substantial similarity is not limited to the protected elements of the plaintiff’s work; any similarities may be probative of actual copying. However, the unlawful appropriation prong requires substantial similarities to the protected elements of the copyrighted work. The Court noted that the use of the same term for two different tests has caused confusion, and therefore implemented the term “probative similarity” when referring to actual copying, and “substantial similarity” in the case of unlawful appropriation. The Court went on to explain that in the case of thin copyright protection such as this, proving unlawful appropriation requires more than a substantial similarity; only a “virtually identical” plan will infringe.

The Seventh Circuit then turned to the issues of scènes à faire and merger. Citing its detailed analysis in Lexington Homes, the Court noted that arrangements of rooms in Design Basics’ floor plans were largely scènes à faire, deserving no copyright protection. For example, placement of the dining room near the kitchen and a bathroom near the bedrooms is rudimentary, commonplace and standard, and [...]
