At a Glance
Authority
TIPO — Taiwan Intellectual Property Office (台灣智慧財產局, Taipei; under Ministry of Economic Affairs, R.O.C.). Patent Act (專利法, Republic of China), most recently amended 2019.
Patent types
Three types: (1) Invention patents (發明專利) — 20 years from filing; full examination; (2) Utility model patents (新型專利) — 10 years; products/devices/structures only; registered after formal review without full inventive step examination; (3) Design patents (設計專利) — 15 years; ornamental design.
Grace period
YES — 6 months for applicant's OWN prior disclosures (Patent Act Art. 22(3)). Covers disclosures made by or derived from the applicant. Shorter than US (12 months AIA § 102(b)(1)(A)) and shorter than Japan (12 months as of 2012). EPC: no own-disclosure grace period.
Utility model
YES — 10-year term; REGISTERED without full examination (TIPO conducts only formal + prior art search; does NOT examine for inventive step); PRODUCTS/STRUCTURES only — processes, methods, and chemical compositions are excluded. Faster and cheaper than invention patent. Can be converted to/from invention patent application.
PCT member?
No — Taiwan is NOT a PCT member because it lacks UN membership. Applicants must file separately in each jurisdiction. Taiwan has PPH agreements with USPTO, JPO, KIPO, EPO, CNIPA, and others to accelerate prosecution.
Software patents
Taiwan's Patent Act excludes 'rules and methods for playing computer games or performing mental acts' but does NOT categorically exclude all software. Computer-implemented inventions with technical character and practical industrial applicability are patentable. TIPO examines software patents under technical effect doctrine, similar to EPO but somewhat more permissive.
Design patents
15-year term. Taiwan design patents cover the ornamental appearance of a product (shape, pattern, color, or combination). Partial design patents available (protecting part of a product's appearance). Icon/GUI design patents available since 2014 amendment.
Enforcement
Intellectual Property Court (IPC, established 2008) — specialist IP court in Taiwan; civil and criminal jurisdiction; fast 6–12 month first-instance timelines vs. general courts; specialized IP judges; widely considered one of Asia's better IP enforcement environments.
Industry Context
Taiwan IP in key sectors
TSMC and the semiconductor process node IP arms race
Taiwan Semiconductor Manufacturing Company (TSMC, 台積電, Hsinchu Science Park; NYSE: TSM and TWSE: 2330; founded 1987 by Morris Chang; ~$600–700B market cap 2023–2024; world's most advanced semiconductor foundry): TSMC does not design chips but manufactures chips designed by fabless semiconductor companies (Apple, NVIDIA, AMD, Qualcomm, MediaTek, Broadcom, Intel Foundry Services). TSMC's competitive moat is built substantially on proprietary process node IP — the manufacturing recipes, equipment configurations, photolithography sequences, and materials science that enable transistor densities no other foundry can match. Key TSMC patent domains: (1) FinFET (fin field-effect transistor) process integration: 3D transistor geometry enabling sub-20nm nodes; TSMC's FinFET implementation patents (first TSMC FinFET at 16nm in volume production 2015) cover fin height/pitch/shape control, gate dielectric deposition, source/drain epitaxial growth; (2) EUV (Extreme Ultraviolet Lithography) process recipes: TSMC works in close collaboration with ASML (monopoly supplier of EUV scanners — ASML NXE:3400 series at 5nm, EXE:5000 High-NA at 2nm); while ASML owns the EUV scanner patents, TSMC holds process integration patents for using EUV in its multi-patterning schemes; (3) CoWoS (Chip-on-Wafer-on-Substrate) advanced packaging: TSMC's 2.5D interposer packaging technology for HBM (High Bandwidth Memory) + logic die integration; essential for NVIDIA H100/H200 AI GPU manufacturing; CoWoS capacity is a global constraint in AI accelerator supply chain 2023–2024; integration layer design + TSV (through-silicon via) density patents; (4) N3/N2 process development: 3nm and 2nm node process patents (gate-all-around [GAA] transistors for N2); TSMC's N3 process (manufacturing Apple M3, Qualcomm Snapdragon 8 Gen 3, NVIDIA H100 successor) involves hundreds of patents on photolithography patterning, dielectric film deposition, and etch process chemistry; (5) TSMC-Apple partnership: Apple and TSMC entered a strategic long-term supply agreement around 2012–2014; Apple's A-series and M-series chips manufactured exclusively at TSMC on leading-edge nodes; TSMC-Apple joint process development work generates joint IP in some areas. TSMC files patents primarily at USPTO and Taiwan TIPO. TSMC's semiconductor IP dispute with Samsung: TSMC and Samsung have an ongoing patent dispute (multiple lawsuits in US and Taiwan) over foundry process technology; specific claims relate to FinFET process integration techniques. GlobalFoundries sued TSMC (2019) for 25 process patent claims in the US, EU, and Germany; settled (terms undisclosed) 2021.
HTC and the smartphone patent wars
HTC Corporation (宏達電, Taoyuan; TWSE: 2498; founded 1997 by Cher Wang, H.T. Cho, and Peter Chou; peak market cap ~$33B 2011; significant decline since 2015): HTC was the world's leading Android smartphone manufacturer by revenue in 2011 and was at the center of some of the most significant smartphone patent wars of the 2010s. Key patent litigation: (1) HTC vs. Apple: Apple sued HTC for patent infringement (ITC Investigation No. 337-TA-710 and 337-TA-721; filed March 2010 — Steve Jobs personally oversaw filing); Apple alleged HTC infringed 20 patents related to iPhone's hardware, user interface, and software architecture (including multi-touch, slide-to-unlock, data tap detection); ITC ruled HTC infringed Apple's US 5,946,647 (data tap detection to display phone numbers in text as tappable links) in December 2011; HTC and Apple reached a 10-year global patent licensing agreement in November 2012 (terms undisclosed); the settlement allowed HTC to focus on Android handset business without ongoing litigation burden; (2) HTC vs. Nokia: Nokia filed patent infringement suit against HTC (2012) relating to wireless network patents (standard-essential patents including WCDMA/HSPA, H.264 video codec standards); settled with licensing; (3) Google acquisition of HTC's design division: Google acquired HTC's Pixel design and engineering team for $1.1B in September 2017 (not the full HTC company; Google also received a non-exclusive IP license to HTC's IP portfolio as part of the deal); this gave Google direct hardware development capability for Pixel phones and access to HTC's implementation patents; (4) HTC's remaining business: HTC retained its remaining phone operations (though much diminished) and pivoted to VR hardware (HTC VIVE headsets — SteamVR tracking patents, lighthouse tracking system, VIVE XR Elite). HTC's smartphone patent portfolio: during peak operations, HTC held thousands of US and Taiwan patents on handset design, radio frequency engineering, manufacturing processes, and software UX. After the decline in market share, HTC has monetized portions of its patent portfolio through licensing.
MediaTek, ASUS, Foxconn and the broader Taiwan technology IP landscape
MediaTek Inc. (聯發科技, Hsinchu; TWSE: 2454; ~$40–60B market cap; founded 1997 by Tsai Ming-kai; world's largest mobile chipset vendor by unit volume 2020–2022): MediaTek designs and sells system-on-chip (SoC) solutions for smartphones, smart TVs, tablets, IoT, and automotive. Dimensity mobile platform patents: LTE/5G modem integration patents; heterogeneous multi-core CPU architecture (MediaTek's big.LITTLE implementation); Wi-Fi/Bluetooth combo chip integration patents; AI-integrated NPU (neural processing unit) for on-device inference; HEVC/H.265, VVC/H.266 codec implementation patents; MediaTek competes with Qualcomm (Snapdragon) and Apple (A-series) in flagship mobile chips. MediaTek was for a long time primarily oriented toward mid-range chips where Qualcomm did not focus; the Dimensity 9000/9200/9300 series entered flagship territory from 2022 onward. ASUSTeK Computer Inc. (華碩電腦, Taipei; TWSE: 2357; ~$15–20B market cap): PC motherboard patents (ATX form factor design, BIOS firmware patents, VRM power delivery circuit patents); ROG (Republic of Gamers) gaming peripherals; ASUS ZenFone smartphone display and camera patents; ASUS has a significant US patent filing program. Hon Hai Precision Industry / Foxconn (鴻海精密, New Taipei; TWSE: 2317 + NYSE: HNHPF; ~$40–50B market cap; world's largest electronics contract manufacturer; ~1M+ employees at peak): Foxconn manufactures iPhones, iPads, Xboxes, and other major consumer electronics for Apple, Microsoft, Sony, and other brands; Foxconn's IP is primarily manufacturing-process focused: automated assembly robot patents, precision fixture design for complex assemblies, SMT (surface-mount technology) process patents for sub-millimeter component placement, iPhone chassis CNC machining process patents. CTBC Bank and financial tech: Taiwan fintech patents in mobile payment, blockchain for supply chain. Delta Electronics (Taipei; power electronics, EV charging station patents, industrial automation). Largan Precision (Taichung; smartphone camera optical lens system patents — world's largest smartphone camera lens manufacturer; Apple iPhone rear camera lens array primary supplier; patent disputes with Sunny Optical China). AU Optronics and Innolux: TFT-LCD and OLED display manufacturing patents; contested heavily in cross-licensing disputes with Samsung, LG, and Corning.
Taiwan's utility model system and patent strategy for hardware startups
Taiwan's utility model (新型專利) is one of the most commercially useful aspects of the Taiwanese patent system for hardware companies: (1) How it works: a utility model covers the shape, structure, or composition of an article (product); it does NOT cover processes, methods, or chemical compositions (key limitation). TIPO registers the utility model after a formal examination (checking filing requirements and patentability form) and a prior art search, but does NOT substantively examine whether the claimed invention would have been obvious to a person of ordinary skill in the art (POSITA). The utility model issues much faster (typically 6–12 months) and at lower cost than a full invention patent (20-year term, full examination, 2–4 year pendency); (2) Technical Assessment (技術報告) requirement: unlike most countries with utility models, Taiwan requires that a utility model owner obtain a Technical Assessment Report from TIPO before initiating infringement litigation. The Technical Assessment Report (TAR) assesses the novelty and inventive step of the utility model on the merits. Without a TAR, a utility model can be registered and used as a commercial signal (deterrent) but cannot be enforced in court. The TAR requirement prevents bad-faith enforcement of clearly invalid utility models; (3) Dual filing strategy: Taiwan permits an applicant to file both an invention patent application and a utility model application for the same invention simultaneously — with the caveat that only one of the two rights can be maintained once both are examined; the applicant must choose. This dual-filing approach allows a company to obtain the utility model quickly (6–12 months) for immediate commercial protection while the longer invention patent examination (2–4 years) is pending; (4) Use cases for hardware startups: Taiwanese hardware startups (especially in consumer electronics, power tools, bicycle components, and medical devices) routinely file utility models as their first IP protection before full invention patents are examined; (5) Conversion: a utility model application can be converted to an invention patent application (or vice versa) before examination begins — useful strategic flexibility. Compare: German Gebrauchsmuster [10yr, products, registered]; Czech vzor užitný [4–10yr, products, registered]; Japanese Jitsuyou Shin-an [10yr, products]; Korean Utility Model [10yr, products]. Taiwan's utility model — like most Asian utility models — is a practical tool for fast, low-cost protection of hardware innovations.

FAQ
Frequently asked questions
What is Taiwan's grace period and how does it compare to US and Japan?
Taiwan's Patent Act Article 22(3) provides a 6-month own-disclosure grace period: disclosures made by the applicant (or by a person who learned the invention from the applicant) within 6 months before the Taiwan filing date do not count as prior art that would destroy novelty of a Taiwan invention patent application. This is shorter than the US AIA § 102(b)(1)(A) 12-month own-disclosure grace period and shorter than Japan's 12-month grace period (which was extended from 6 months to 12 months effective April 1, 2012). EPC countries (Germany, France, Netherlands, UK, Sweden, etc.) have NO comparable own-disclosure grace period — any public disclosure before the EPC filing date destroys European patent rights. Practical implications: (1) if an inventor presents research at a conference in Taiwan (without a prior filing), the inventor has a 6-month window to file a Taiwan patent application — but only 6 months, not 12; (2) the grace period is available only for the applicant's own disclosures; third-party independent disclosures within the 6-month window are not covered and would be prior art; (3) for US protection, the US AIA 12-month window provides more time, but the safest strategy remains to file before any disclosure; (4) Taiwan's Patent Act also covers disclosures made by 'exhibition at specified international exhibition' (Art. 22(3)(2)) within 6 months — parallel to EPC Art. 55 but Taiwan's version applies to designated exhibitions rather than the narrow EPC recognized exhibitions list. For companies launching hardware products globally, the best practice remains: file the Taiwan and PCT-equivalent filings before any product launch, trade show demonstration, or press release about the invention.
How did HTC's smartphone patent wars with Apple end and what was the long-term outcome?
HTC's smartphone patent wars with Apple ended with a global settlement in November 2012: Apple and HTC agreed to a 10-year patent licensing agreement covering current and future patents held by both companies, with undisclosed financial terms. The settlement came after the US International Trade Commission (ITC) found in December 2011 that HTC infringed Apple's US 5,946,647 (a patent covering detection of data patterns like phone numbers in text to make them actionable/tappable links) and issued an exclusion order (import ban) against certain HTC products. The settlement resolved this ITC case and all pending litigation between Apple and HTC in multiple jurisdictions. Long-term outcome for HTC: the settlement resolved the immediate litigation but did not reverse HTC's broader commercial decline. HTC peaked in market capitalization at approximately $33 billion in 2011. By 2013–2015, HTC's smartphone market share was rapidly eroded by Samsung in the Android market and by Apple in the premium segment. The patent litigation with Apple had consumed significant legal resources. By 2017, HTC agreed to sell its Pixel smartphone design and engineering division to Google for $1.1 billion, with Google also receiving a non-exclusive IP license to HTC's patent portfolio. HTC retained its VIVE VR headset business. The HTC-Apple case is significant in patent history as an early example of a smartphone patent war's economic destructiveness — the legal costs, management distraction, and supply chain uncertainty contributed to HTC's competitive decline even after settlement. It also illustrated the strategic importance of patent portfolio management in smartphone hardware manufacturing: a patent dispute with a dominant platform holder can be existentially threatening even for a market-leading hardware manufacturer.
Why is TSMC's semiconductor IP so strategically important and how is it protected?
TSMC's semiconductor IP is arguably the most strategically critical manufacturing IP in the world as of 2024: (1) Why it matters: TSMC manufactures essentially all of the world's most advanced semiconductors (below 10nm node) — Apple's A-series and M-series chips, NVIDIA's H100/H200/Blackwell AI GPUs, AMD Ryzen processors, Qualcomm Snapdragon, MediaTek Dimensity. No other foundry can manufacture at 3nm or 2nm in volume. The IP gap between TSMC and its nearest competitor (Samsung Foundry) is estimated at 1–2 process generations; (2) How TSMC's IP is protected: TSMC's process technology IP is protected through a combination of patents, trade secrets, and practical barriers to replication. TSMC holds thousands of US patents, Taiwan patents, and has active patent families in Japan, South Korea, and Europe. Process recipe details (specific equipment settings, gas flow parameters, dielectric film compositions, annealing temperatures) are maintained as closely guarded trade secrets — they are NOT publicly disclosed in patent applications to the extent possible; (3) Trade secret primacy over patents: the most valuable aspects of TSMC's manufacturing know-how are trade secrets, not patents. A patent requires disclosure of the invention to the public. If a semiconductor process recipe is described with enough detail to be enabled, competitors could theoretically study the patent and attempt replication. TSMC deliberately keeps the deepest process recipe details as trade secrets, filing patents primarily on broader architectural concepts (the what and why, not the exact how); (4) Geopolitical dimension: TSMC's IP concentration in Taiwan has become a significant geopolitical concern. The US CHIPS and Science Act (2022) provided $52B in US semiconductor manufacturing incentives, partly to encourage TSMC to build fabs in the US (TSMC announced a $40B fab investment in Arizona). The concentration of advanced semiconductor manufacturing IP in one company in one location is considered a strategic risk by US, European, and Japanese governments; (5) IP litigation: TSMC has been involved in significant patent disputes including with GlobalFoundries (settled 2021 after GlobalFoundries filed suit alleging TSMC infringed 25 process patents) and with Samsung. TSMC trade secret cases are rarer but significant — TSMC has brought criminal charges in Taiwan against former employees who allegedly took process IP to Chinese competitors.
What is Taiwan's utility model (新型專利) and when should it be used?
Taiwan's utility model (新型專利) is a 10-year registered patent for the shape, structure, or composition of a physical article: (1) What it covers: utility models in Taiwan cover the three-dimensional form or structural arrangement of a physical product — the shape, structure, and physical composition (not chemical composition) of a manufactured article. This includes hardware products, mechanical structures, electronic device housings, component arrangements inside a device, bicycle components, tool designs, medical device structures, etc. Importantly, processes and methods are NOT covered — if the invention is a method of manufacturing something, or a software algorithm, or a chemical composition, a utility model is not appropriate; (2) How it works: TIPO registers the utility model after a formal examination (checking required formalities and conducting a prior art search) but WITHOUT conducting a substantive examination for inventive step — the patentable non-obviousness of the claimed invention is NOT assessed before registration. This makes it much faster (6–12 months vs. 2–4 years for a full invention patent) and cheaper; (3) Technical Assessment Report (TAR) requirement: Taiwan requires a utility model owner to obtain a Technical Assessment Report from TIPO before starting infringement litigation. The TAR is a substantive examination of novelty and inventive step. Without a TAR, the utility model exists but cannot be enforced in court. The TAR requirement is a consumer protection measure preventing the proliferation of invalid utility models being used for extortionate litigation; (4) Dual filing strategy: Taiwan allows simultaneous filing of both an invention patent and a utility model for the same invention. The utility model issues quickly (protecting the invention during the longer invention patent prosecution) and the applicant chooses which right to maintain after both are examined. This is a powerful strategic tool: get fast protection via utility model while invention patent examination proceeds; (5) Conversion: a pending utility model application can be converted to an invention patent application before TIPO's initial examination; (6) Best use cases: hardware products with short commercial lifecycle (where 10 years is sufficient); situations where a competitor is about to launch a similar product and fast protection is needed; situations where the invention is in the structure/form domain rather than a process or method.
Why is Taiwan not a PCT member and how does this affect patent filing strategy?
Taiwan is not a member of the Patent Cooperation Treaty (PCT) because PCT membership requires UN membership, and Taiwan is not a UN member state (the People's Republic of China holds the 'China' seat at the UN since 1971, displacing the Republic of China/Taiwan). This creates a significant practical disadvantage for Taiwanese applicants and companies seeking international patent protection: (1) No single PCT application: while a US, European, Japanese, or Korean company can file a single PCT application (with one set of fees and one filing) and effectively placeholder rights in 150+ countries for 30 months, a Taiwanese company must file separate national or regional applications in each target jurisdiction from the outset — USPTO, EPO, JPO, KIPO, CNIPA, etc. — each with separate filing fees and translation requirements. This substantially increases the upfront cost of international patent protection; (2) No 30-month window: PCT provides a 30-month window from priority date to decide which countries to enter (national phase). Taiwanese companies without PCT must typically file within 12 months of their Taiwan priority date in each target country under the Paris Convention. The Paris Convention is available to Taiwan through bilateral mutual recognition agreements; (3) PPH as compensation: Taiwan has actively pursued Patent Prosecution Highway (PPH) agreements with the USPTO, JPO, KIPO, EPO, CNIPA, and other major offices. PPH allows an applicant who has received an allowable claim in one office to request accelerated examination in another office based on the favorable examination results. While not equivalent to PCT, PPH significantly reduces prosecution time and cost in partner offices; (4) Taiwan's WIPO workaround: Taiwan is not a WIPO member (World Intellectual Property Organization) but participates in international patent cooperation through bilateral and multilateral agreements. TIPO has data-sharing arrangements with major patent offices; (5) Practical impact: major Taiwanese semiconductor and electronics companies (TSMC, MediaTek, ASE Group, AU Optronics) build large international patent portfolios by filing directly at USPTO (most important market for licensing and litigation), EPO, JPO, and KIPO. The added cost of non-PCT filing is absorbed as a business cost for companies at this scale. For smaller Taiwanese companies and startups, non-PCT membership significantly increases the financial barrier to international patent protection.
