For more than 80 years, Clarín has been making x-frame folding chairs. In 1999 it applied for registration of one particular x-frame design as a trademark. The Patent and Trademark Office issued Registration No. 2,803,875 in January 2004. This is the registered mark:
The principal register describes it thus: “a configuration of a folding chair containing an X-frame profile, a flat channel flanked on each side by rolled edges around the perimeter of the chair, two cross bars with a flat channel and rolled edges at the back bottom of the chair, one cross bar with a flat channel and rolled edges on the front bottom, protruding feet, and a back support, the outer sides of which slant inward.”
Clarín was acquired by Greenwich Industries in 1993. We refer to Greenwich Industries as Clarín, the name under which it does business. Harvey Hergott, Clarin’s general manager at the time of the acquisition, left later that year and, after honoring a five-year restrictive covenant, joined Specialized Seating, Inc., in 2001, two years after his son Alfred had founded that business. Specialized competes in Clarin’s principal market: the sale of folding chairs to auditoriums, sports stadiums, convention centers, and other places that need to deploy lots of seats, which owners want to be as light and compact as possible for storage when not in use. Specialized sells a folding chair that to an untrained eye looks like Clarin’s trademark chair. There are differences in construction and detail; the chair is not a slavish knockoff, but the basic design tracks the registered mark. That similarity had led to this litigation in which Specialized sought a declaratory judgment that its design does not violate Clarin’s rights under the Lanham Act, 15 U.S.C. §§ 1051-1129, and Clarín counterclaimed for an injunction.
Clarín has been using the mark long enough for its registration to be “incontestable” under 15 U.S.C. § 1065. The word “incontestable” is misleading, however, because an incontestable mark may be contested, and defeated, on many grounds. The principal effect of incontestable status is to relieve the trademark proprietor of any need to show “secondary meaning”— in other words, whether consumers associate a mark with a particular producer is not relevant when the mark is incontestable. Clarin’s customers buy in bulk and are sophisticated; it is exceedingly unlikely that any of them is confused about who makes which chair. Because the mark is incontestable, however, the absence of confusion does not matter. Still, nine defenses are available to a person charged with infringing an incontestable mark. 15 U.S.C. § 1115(b). Specialized Seating asserted two of these defenses: that “the registration ... was obtained fraudulently” (§ 1115(b)(1)) and that “the mark is functional” (§ 1115(b)(8)).
The district court held a bench trial and ruled in Specialized’s favor on both of these issues.

Clarin chairs with a-back designs failed when the audience at rock concerts, seeking a better view, sat on top of the chairs’ backs and put their feet on the seats. The tubing buckled at the bend in the frame. The b-back design is less likely to buckle when someone sits on it, and it also produces a somewhat wider back, which concert promoters see as a benefit. (Patrons sometimes try to get closer to the stage by stepping through rows of chairs. The gap between b-back chairs is smaller, so they are more effective at keeping crowds in place.)
Having concluded not only that the overall design of Clarin’s chair is functional, but also that each feature is functional, the district judge added that Clarin had defrauded the Patent and Trademark Office by giving misleadingly incomplete answers to the trademark examiner’s questions. The examiner initially turned down Clarin’s proposal to register the design as a trademark, observing that the design appeared to be functional. Clarin replied that the design was chosen for aesthetic rather than functional reasons. (This was not a complete answer, as attractiveness is a
kind
of function. See

that a patent it held on an x-frame chair, No. 1,943,058, issued in 1934, did not include all of the features in the mark’s design. What Clarin did not tell the examiner is that it held three other patents on x-frame designs: No. 1,600,248, issued in 1926; No. 2,137,803, issued in 1938; and No. 3,127,218, issued in 1964. The district judge concluded that the four patents collectively cover every feature of the design submitted for a trademark except the b-back, and that as the b-back is a functional improvement over the a-back Clarin should have disclosed all of these utility patents. Had it done so, the judge thought, the examiner would have refused to register the proposed mark.
Clarin’s appeal was delayed by settlement negotiations. Briefing and argument were deferred until after they broke down. It was further delayed by the district court’s failure to enter a proper judgment, a common problem in the Northern District of Illinois. See, e.g.,
Rush University Medical Center v. Leavitt,
Findings of fact made after a bench trial must stand unless clearly erroneous. Fed.R.Civ.P. 52(a)(6);
Anderson v. Bessemer City,
Clarin tries to evade this standard of review by contending that the district judge’s findings were influenced by legal errors. We don’t see any. The district judge started from the proposition, which the Supreme Court articulated in
TrafFix,
that claims in an expired utility patent presumptively are functional. Since utility patents are supposed to be restricted to inventions that have utility, and thus are functional, that’s a sensible starting point — and since inventions covered by utility patents pass into the public domain when the patent expires, it is inappropriate to use trademark law to afford extended protection to a patented invention.

Jay Franco,
We do not doubt that there are many other available functional designs. Sometimes the function of the functionality doctrine is to prevent firms from appropriating basic forms (such as the circle) that go into many designs. Our contemporaneous opinion in Jay Franco discusses that aspect of the functionality doctrine. This does not imply that preserving basic elements for the public domain is the doctrine’s only role.
Another goal, as TrafFix stressed, is to separate the spheres of patent and trademark law, and to ensure that the term of a patent is not extended beyond the period authorized by the legislature. A design such as Clarin’s x-frame chair is functional not because it is the only way to do things, but because it represents one of many solutions to a problem. Clarín tells us that other designs are stronger, or thinner, or less likely to collapse when someone sits on the backrest, or lighter and so easier to carry and set up. Granted. But as Clarin’s '248 patent states, the x-frame design achieves a favorable strength-to-weight ratio. Plastic chairs are lighter but weaker. Y-frame chairs are stronger but use more metal (and so are heavier and more expensive); some alternative designs must be made with box-shaped metal pieces to achieve strength, and this adds to weight and the cost of fabrication. The list of alternative designs is very long, and it is easy to see why hundreds of different-looking folding chairs are on the market.
What this says to us is that
all
of the designs are functional, in the sense that they represent different compromises along the axes of weight, strength, kind of material, ease of setup, ability to connect (“gang”) the chairs together for maximum seating density, and so on. A novel or distinctive selection of attributes on these many dimensions can be protected for a time by a utility patent or a design patent, but it cannot be protected forever as one producer’s trade dress. When the patent expires, other firms are free to copy the design to the last detail in order to increase competition and drive down the price that consumers pay. See, e.g.,
Bonito Boats, Inc. v. Thunder Craft Boats, Inc.,
Clarín reminds us that a product whose overall appearance is distinctive can be protected under the trademark laws, even though most of the product’s constituent elements serve some function. See, e.g.,
Service Ideas,
Because the district court did not commit clear error in finding Clarin’s design to be functional, it is unnecessary to decide whether Clarín committed fraud on the Patent and Trademark Office. All a finding of fraud does is knock out the mark’s “incontestable” status, and its registration, under § 1115(b)(1). It does not affect the mark’s validity, because a trademark need not be registered to be enforceable. See
Orient Express Trading Co. v. Federated Department Stores, Inc.,
Clarín contends that we should consider this topic even though it does not affect Specialized’s right to sell a copycat chair, because it might matter to attorneys’ fees, but fees have not been awarded. A decision on legal issues just because they might matter to some later dispute would be advisory. Clarín also appears to be concerned that the district judge’s finding of fraud might affect future litigation against a different competitor, but issue preclusion (collateral estoppel) applies only to issues actually
and necessarily
resolved in the first case.
