Design Patent

A design patent protects the ornamental appearance — the visual, aesthetic, or decorative aspects — of an article of manufacture. This includes: the shape and configuration of an object (e.g., the curved rectangular form of a smartphone); surface ornamentation applied to an article (e.g., a pattern on fabric or a graphical user interface icon); or a combination of shape and surface ornamentation. A design patent does NOT protect: the functional aspects of a design (how something works — that requires a utility patent); any design that is purely functional with no aesthetic component; the article of manufacture itself (you cannot design-patent the generic article, only its particular ornamental appearance). The single claim in a design patent is standardized: 'The ornamental design for [article of manufacture], as shown and described.' The drawings entirely define the scope of protection — unlike utility patents, where the written claims define scope, in design patents the drawings are the claim. Solid-line features are claimed; broken-line features are not part of the claimed design and appear only for environmental context. Famous design patents: Apple's D618,677 (original iPhone's rounded rectangle front face); Crocs' shoe design (D517,789); the Statue of Liberty (U.S. Design Patent 11,023 — one of the earliest U.S. design patents); computer icon and GUI designs are common subject matter for design patents.

Design patent infringement is analyzed under the Egyptian Goddess test, established by the Federal Circuit en banc in Egyptian Goddess, Inc. v. Swisa, Inc., 543 F.3d 665 (Fed. Cir. 2008). The test: 'An ordinary observer, giving as much attention as would a purchaser of such goods, who is familiar with the prior art, would be deceived into thinking the accused design is the same as the patented design, such that they would purchase the accused design thinking it was the patented design.' Key elements: (1) The observer is an 'ordinary observer' familiar with the prior art — not a design expert, but someone who knows what similar designs exist in the market. If the prior art includes many similar designs, the ordinary observer will be more discriminating and require more similarity for infringement. (2) The comparison is between the OVERALL APPEARANCES of the patented and accused designs — not feature-by-feature comparison. (3) Functional aspects are excluded from the comparison — if a design feature is purely functional (the only possible way to achieve a function), it is not considered in the infringement analysis. (4) The accused design does not need to be identical — 'substantially similar' is sufficient. But the similarity must be enough that the ordinary observer would be deceived into thinking they are the same design. Prior art context: if the patented design is very similar to prior art, even small differences between the patented and accused designs may be meaningful to an ordinary observer familiar with those prior art designs. A patent on a very crowded design space has a narrow scope of protection.

Design patent infringement provides two potential damages measures, one of which is unique to design patents and potentially very powerful: (1) Total profit under 35 U.S.C. § 289: the infringer's TOTAL PROFIT from the sale of the 'article of manufacture' to which the patented design was applied. Unlike utility patent damages (which require apportionment of the patent's contribution to the overall product's value), § 289 traditionally allowed recovery of total profit from the entire infringing product with no apportionment. This made design patent damages potentially enormous — Samsung's case is the most prominent example. Apple v. Samsung Electronics, 580 U.S. 53 (2016): Samsung infringed Apple's design patents covering the iPhone's rounded-corner rectangle front face, bezel, and colorful app icon grid. The district court awarded Samsung's total profits from smartphone sales ($399M). The Supreme Court reversed and remanded, holding that the 'article of manufacture' to which the design was applied could be a COMPONENT of the product (e.g., the front face of the phone), not necessarily the entire phone. The case was remanded to determine whether the relevant article is the phone or a component. This 'article of manufacture' question has been heavily litigated since — the Federal Circuit has not fully settled it, and different components can be the relevant article depending on the facts. (2) Reasonable royalty under § 284: the patent holder may alternatively (or additionally where § 289 is insufficient) recover a reasonable royalty — the same standard as utility patent reasonable royalty damages (hypothetical negotiation, Georgia-Pacific factors). In practice, § 289 total profit claims are often pursued because they can be larger than reasonable royalty awards, especially for infringement of designs on consumer products.

Design patents and trade dress are two overlapping but distinct forms of protection for product appearance. Design patent: (1) Federal patent statute (35 U.S.C. § 171). (2) Protects ornamental appearance of articles of manufacture — shape, configuration, surface ornamentation. (3) 15-year term from grant — fixed, not renewable. (4) No requirement of distinctiveness or secondary meaning — just novelty and non-obviousness. (5) Protection begins on grant date, not on use. (6) Strong, clear scope defined by drawings. (7) Total profit damages under § 289. Trade dress: (1) Federal Lanham Act (15 U.S.C. § 43(a)) and state unfair competition law. (2) Protects distinctive product appearance that functions as a source identifier (tells consumers who made it). (3) Indefinite duration — lasts as long as distinctiveness and use continue. (4) Requires distinctiveness: either inherent distinctiveness (unusual, unique appearance) or secondary meaning (consumers have learned to associate the appearance with a particular source). (5) Must be non-functional — purely functional design features cannot be trade dress (Traffix Devices v. Mktg. Displays, S.Ct. 2001). (6) Can be registered as a trademark (very difficult to obtain registration for product shape/configuration). (7) Infringement: likelihood of confusion standard. Strategy: file both. Design patents are strong for immediate, clear protection — especially during the critical early commercial period when copying is most damaging. As the product gains market recognition, trade dress protection grows stronger. The combination creates overlapping layers of protection: design patent for 15 years, trade dress potentially indefinitely if the appearance becomes distinctive.

Yes — graphical user interface (GUI) elements, icons, and computer-generated images displayed on a screen or other display device can be protected by design patents. The article of manufacture is the display device (screen, monitor, mobile device) showing the design. USPTO examination of GUI design patents: (1) The design must be ornamental and must be embodied in an article of manufacture — the display showing the image qualifies. (2) The claim covers 'the ornamental design for a display screen with [icon/GUI element/animated sequence], as shown and described.' (3) The drawings show the GUI element as displayed on a device (often shown with broken lines for the device/screen frame, solid lines for the GUI design). (4) Animated sequences can be patented as design patents showing multiple views of each animation frame; each frame view is a stage in the animation sequence. Scope and infringement: GUI design patent infringement is judged by the same Egyptian Goddess ordinary observer test. The comparison is between the overall visual appearance of the patented GUI design and the accused design as displayed. Functional elements of a GUI (a button that must be shaped a certain way to convey its function) are excluded. Key examples: Apple has extensive GUI design patents covering iOS icon designs, app switcher animations, and screen layouts. Google has design patents on Android GUI elements. Many tech companies maintain GUI design patent portfolios as part of their overall IP strategy. International: Hague Agreement allows international registration of GUI designs in participating countries. The EU (EUIPO) is a major destination for GUI design protection globally.
