Industrial Design Patents

Industrial design patents (called simply 'design patents' in the US) protect the ornamental appearance of a manufactured article — what something looks like rather than how it works: DESIGN PATENT SCOPE: a design patent protects the new, original, and ornamental design of an article of manufacture; the single claim is always in the form: 'The ornamental design for [article name], as shown and described'; the drawings ARE the claim — the scope of protection is defined by what is shown in solid lines in the design patent drawings; broken lines in design patent drawings indicate environmental features — they are not claimed and not part of the protected design; WHAT DESIGN PATENTS COVER: the overall appearance of a product (shape; surface ornamentation; configuration; color in some jurisdictions); graphical user interface (GUI) elements (Apple; Google; Samsung extensively use design patents for icon designs; screen layouts; swipe animations; icon grids); packaging design (Coca-Cola bottle shape; Leatherman tool shape; OXO Good Grips handle); product configurations (Apple iPhone rounded rectangle; AirPods case shape; Stanley Quencher cup with handle holes); WHAT DESIGN PATENTS DO NOT COVER: functional features (features that are driven entirely by their function with no alternative ornamental choices); methods and processes (no process claims); internal components invisible during normal use; CONTRAST WITH UTILITY PATENTS: utility patent = HOW something works (function; mechanism; process); design patent = WHAT something looks like (appearance; form; ornament); utility: multiple claims; design: single claim; utility: 20 years from filing; design: 15 years from grant (post-AIA; pre-AIA: 14 years); utility: maintenance fees due; design: no maintenance fees; CONTRAST WITH TRADE DRESS: trade dress (Section 43(a) Lanham Act): protects product appearance that has acquired distinctiveness identifying source; advantages of design patent over trade dress: no distinctiveness requirement; no need to prove acquired secondary meaning; defined term of protection (not potentially unlimited); advantages of trade dress over design patent: potentially unlimited duration; covers functional configurations when proven non-functional via secondary meaning; both can coexist: Apple protects iPhone appearance via both design patents and trade dress.

The Apple v. Samsung smartphone litigation is the most consequential design patent case in US history, ultimately reaching the Supreme Court and fundamentally changing how design patent damages are calculated: THE CORE DISPUTE: Apple sued Samsung in the Northern District of California in 2011, asserting multiple intellectual property rights including three design patents: US D593,087: the rectangular front face of the iPhone with rounded corners and a black bezel; US D618,677: the beveled edge bezel of the iPhone; US D604,305: the colorful grid of icons displayed on the iPhone screen (graphical user interface); APPLE'S THEORY: Samsung's Galaxy S, Galaxy S II, and other Android phones infringed Apple's design patents and trade dress by copying the iPhone's distinctive appearance; JURY VERDICT (August 2012): jury awarded Apple $1.049 billion in damages; included both design patent and trade dress damages; design patent damages calculated under 35 U.S.C. § 289 which provides that an infringer shall pay the 'total profit' from the infringer's 'article of manufacture'; Samsung argued this should be profits on the component (display; housing) not the entire phone; FEDERAL CIRCUIT AFFIRMED: Federal Circuit affirmed most of the jury verdict; reduced some to $930M; SAMSUNG'S SUPREME COURT PETITION: Samsung petitioned the Supreme Court to consider: What is the 'article of manufacture' for § 289 design patent total profit calculation — the entire phone or just the component that includes the patented design?; SUPREME COURT (December 2016): unanimous reversal; 'article of manufacture' can be a component of the sold product, not necessarily the entire sold product; the relevant article of manufacture is the 'thing that was made' and to which the design was applied; the Court established a four-factor test for determining which components are the relevant article; REMAND AND SETTLEMENT: after remand for further proceedings, the parties ultimately settled in June 2018; final settlement amount undisclosed; Samsung had paid Apple $548 million prior to settlement; IMPACT ON DESIGN PATENT STRATEGY: after Apple v. Samsung, design patents for consumer electronics, software GUIs, and consumer products became significantly more valuable as offensive and licensing assets; companies dramatically increased design patent filing rates after 2012-2016.

Industrial design protection internationally requires either using the WIPO Hague Agreement system (most efficient for multiple countries) or filing separately in each country: THE HAGUE SYSTEM (WIPO HAGUE AGREEMENT): ONE INTERNATIONAL REGISTRATION COVERING MULTIPLE COUNTRIES: file a single international application with WIPO; designate up to 100+ contracting parties (countries); one set of fees; one filing; one language; WIPO processes the application and transmits to designated offices; each designated office can refuse (based on local requirements) within 6-12 months; if no refusal, the design is protected in that country; TERM: 5-year initial registration; renewable in 5-year increments for up to 25 years (most countries); USPTO JOINED 2015: US is now a contracting party; HAGUE fees: basic fee (CHF 397 for one design) + designation fees per country (varies: EU EUIPO ~CHF 62; US $729 for one design variant); ADVANTAGES: administrative efficiency; single renewal; single ownership changes; WHO USES IT: consumer electronics companies; fashion; automotive; luxury goods for multi-market design protection; MAJOR COUNTRY SYSTEMS: EU (EUIPO): EU Community Registered Design (CRDS); covers all 27 EU member states with one filing; EUIPO fee ~€350 (1 design); €230 for 2nd-10th designs in same class; 5-year terms; up to 25 years; EU Community Unregistered Design Right (CUDR): automatic protection for 3 years from first disclosure in EU; US: 35 U.S.C. §§ 171–173; 15-year term (post-AIA); USPTO design patent application; CHINA: State Intellectual Property Office (CNIPA); 15-year term; high-volume filer (Chinese domestic companies); important for consumer goods market and manufacturing; JAPAN: Japan Patent Office (JPO); interior design protection; GUI protection recently enhanced; KOREA: KIPO; GUI design protection; INDIA: Design Act 2000; 10+5 year term; UK (post-Brexit): UKIPO registered design; 5-year renewable; separate from EU now; DESIGN PATENT vs. COPYRIGHT: in US, design patent must be filed (no automatic protection); copyright on product designs is theoretically available but limited (useful article doctrine: Varsity Brands v. Star Athletica S.Ct. 2017 — separability test for copyright in useful article design); fashion industry: copyright of surface decoration (print patterns) but not clothing silhouette; design patent for 3D article shapes.

The most sophisticated IP strategies use design and utility patents together — they protect different aspects of the same product and address different competitive threats: THE COMPLEMENTARY PROTECTION FRAMEWORK: UTILITY PATENT COVERS THE FUNCTION: how the product works; the technical mechanism; the process; the algorithm; anyone who builds a product with the same function infringes regardless of appearance; utility patents have broader scope but require disclosing how the invention works; DESIGN PATENT COVERS THE APPEARANCE: what the product looks like; anyone who makes a product with the same ornamental appearance infringes regardless of whether they copied the function; design patents are narrower in scope but much faster and cheaper to obtain; COMBINED STRATEGY EXAMPLES: SMARTPHONE: utility patents on touch screen recognition algorithms; battery charging circuits; antenna designs; display technology → PLUS design patents on the screen GUI layout; app icons; device silhouette with rounded corners; CONSUMER PRODUCT (Stanley Quencher cup): utility patent on the handle attachment mechanism; vacuum insulation technology → PLUS design patent on the distinctive cup shape; handle hole configuration; MEDICAL DEVICE: utility patent on the biosensing algorithm; electrode configuration; wireless transmission → PLUS design patent on the device form factor; screen layout; physical button placement; PRACTICAL ADVANTAGES OF EARLY DESIGN PATENT FILING: FASTER TO ISSUE: design patents typically issue in 12-16 months vs. 2-3 years for utility; can provide early protection during a product's critical first-to-market period; CHEAPER: USPTO design patent fee $960 (small entity); utility patent $800 (small entity) just for basic filing + $800 examination + $1,200 search; prosecution total $15,000-25,000 with attorney; NO MAINTENANCE FEES: design patents do not require maintenance fees; utility patents require $1,600 + $3,600 + $7,700 at 3.5; 7.5; 11.5 years (large entity); DESIGN AROUND STRATEGY: when evaluating a competitor's design patent, determine what appears in solid lines (claimed) vs. dashed lines (unclaimed environment); modify the ornamental elements shown in solid lines; if you can achieve the same function with a different appearance, you may avoid infringement; PORTFOLIO BUILDING: file utility applications first to establish priority date for the technical invention; file design applications concurrently for the implemented product's appearance; file continuation design applications as the product design evolves through production.
